About Share Share is a venture-backed internet infrastructure network building Africa's backbone. The company aggregates underutilized telecom infrastructure, fiber, subsea cables, and data centers, and provides ISPs with scalable access to bandwidth without traditional upfront costs. Through an open access model, local internet providers can deliver dramatically faster speeds to their subscribers without raising their own costs. Share's network spans thousands of kilometers of fiber, 12 infrastructure providers, and 10 data centers, reaching over 8 million people across East Africa. The platform team builds the software that makes this work: billing, payments, subscriber management, RADIUS based network authentication, and integrations with ISP billing systems and mobile money providers. We are replacing legacy, non API systems with a modern API platform, and real money is already flowing through the system. This is a small, high intensity engineering team building core infrastructure under real deadlines. You will own entire domains, not tickets. The role We are hiring a VP & Staff Software Engineer to take ownership of the platform's most critical technical domains: the payments pipeline (collections, revenue splitting, treasury operations), the billing engine (subscription lifecycle, cycle management, automated renewals), and the integration layer (BSS/OSS sync with partner systems). You will work directly with the CTO and a small team of engineers to ship production systems that handle real financial transactions for real ISP partners. This is the most senior individual contributor role on the engineering team. You are expected to make architectural decisions, write production code, review others' work, and unblock the team when they hit technical walls. You will not manage people. You will build systems. What you will own Payments domain: SasaPay collections integration (C2B API, STK push, IPN handling), revenue split engine (per partner, per BNG percentage logic), ChoiceBank treasury operations (withdrawals, internal transfers, OTP flows), and the payment completion handler that bridges payment confirmation to subscriber activation. Billing engine: Subscription and BillingCycle lifecycle, automated renewal cron, grace period enforcement, plan change mid cycle logic, and the event driven communication triggers that notify subscribers at every billing moment. Integration layer: Splynx adapter (plan sync outbound, subscriber sync inbound, activation webhooks), custom webhook delivery engine, and the event routing that connects domain events to external system notifications. Architecture decisions: Service boundaries, event contracts (Kafka), data model evolution (Prisma/PostgreSQL), API design for both public and private endpoints, and the migration strategy from the legacy Next.js monolith to the NestJS microservices platform. Technical environment Backend (where you will spend most of your time) NestJS monorepo with 7 microservices (CRM, Billing, Payments, Ledger, Communications, Provisioning, Integrations) TypeScript end to end PostgreSQL with Prisma ORM (shared database, service scoped access) Kafka message bus (migrating from RabbitMQ) for inter service communication (send/emit patterns) Redis for caching, queues, rate limiting, and idempotency REST API gateway with Swagger documentation Payments and financial systems SasaPay (OAuth 2.0, C2B collections, B2B transfers, IPN webhooks) ChoiceBank BaaS API (KYC, internal transfers, OTP based withdrawal confirmation) Revenue split engine with per partner/per BNG/per plan configuration Double entry ledger (AccountTransfer, AccountLedgerEntry, AccountRevenueSplit) M Pesa STK push integration via SasaPay as collections gateway Infrastructure and tooling GitHub Actions CI/CD, SSH deployment to VMs Sentry for error monitoring, Loki + Pino for structured logging (being implemented) Circuit breaker patterns, provider failover, webhook signature verification FreeRADIUS integration for network subscriber provisioning (PPPoE credentials, plan attributes) Legacy system (active, being migrated) Next.js application with API routes (the payments module you'll be refactoring lives here today) Shared Prisma schema with the new platform Active development continues on both repos simultaneously during migration Requirements Non negotiable 7+ years of professional software engineering experience, with at least 3 years in backend systems handling real financial transactions (payments, billing, ledger, or treasury) Deep TypeScript/Node.js expertise. You should be able to design a NestJS microservice from scratch, not just work in one. Production experience with payment gateway integrations (M Pesa, Stripe, Adyen, or similar). You understand STK push flows, webhook idempotency, callback signature verification, and reconciliation. Strong PostgreSQL skills. You can design schemas for financial data, write migrations, and reason about transaction isolation and locking. Experience with event driven architectures (Kafka, RabbitMQ, or similar). You understand the difference between request reply and fire and forget patterns and when to use each. You ship. You can take a spec document and turn it into production code without waiting for someone to break it into small tasks. Strong preference Experience in East African fintech or mobile money ecosystems (M Pesa, SasaPay, Airtel Money). Understanding of Kenya's payment infrastructure and regulatory environment. Experience with ISP billing systems, RADIUS protocols, or telecommunications platforms. Experience with Prisma ORM and NestJS specifically. Production experience with multi tenant SaaS platforms (provider scoped data, API key auth, webhook delivery). Track record of migrating monolithic systems to microservices while keeping production running. AI augmented engineering (required mindset) We expect every engineer at Share to use AI tools as a daily part of their workflow. This is not optional and not aspirational - it is how we operate. Our entire project planning, specification, and documentation process runs through AI assisted sessions. Our codebase includes AI readable context files. We use Claude for architecture decisions, code review, spec generation, and technical writing. What this means for you: You already use AI coding assistants (Claude, Cursor, Copilot, or similar) daily and can articulate how they change your workflow - not just autocomplete, but architectural reasoning, spec review, and debugging. You are comfortable working with AI generated specifications and can critically evaluate them, push back where they are wrong, and extend them where they are incomplete. You see AI as a force multiplier that lets a small team operate at the capacity of a much larger one. You are not threatened by it; you are faster because of it. You are willing to contribute to improving our AI assisted workflows - better prompts, better context files, better session structures. What we offer A seat at the table while we build the technical backbone of Africa's next generation internet - the decisions you make here will be visible in how entire ISP partners run their networks. Competitive salary and meaningful equity in a mission driven, investor backed company (US incorporated; Kenya operating entity). Private health and wellness benefits - we'll walk through these during the process. A high ownership environment with a steep but well supported learning curve, and a team that writes things down.

Worldwide, over 100,000 agents across more than 15,000 branches use Reapit to run their businesses, manage properties, collect rent, engage clients, and provide outstanding customer service every time. What you'll be doing Reporting to the Director of Engineering, you'll operate as a highly senior, technically hands-on backend engineer, embedded into a squad and owning delivery of substantive, cloud-native services end-to-end. Ad-hoc client interaction, supporting requirements discovery and technical solutioning where needed. Architecting, building and shipping complex, high-performance distributed services in C# and .NET Core 8/9 - primarily serverless on AWS Lambda - setting the technical bar for the squad and owning delivery of substantive feature sets end-to-end. Designing data models and persistence patterns across Aurora RDS MySQL and DynamoDB - picking the right tool for the workload, tuning for performance at scale, and modelling for both transactional and high-throughput access patterns. Building resilient, event-driven systems with SQS and related AWS messaging primitives - idempotency, retries, dead-letter handling, and clean separation of concerns across services. Owning each feature's solution end-to-end - partnering with Business Analysts who capture high-level problems and workflows, then driving product thinking, scoping, trade-offs and delivery yourself. Leveraging Claude Code and advanced agentic workflows at pace - orchestrating sub agents, managing context, running parallel workstreams and embedding AI native engineering patterns into everyday delivery. Designing clean, well versioned, well documented APIs that other engineers enjoy consuming - treating developer experience and contract stability as first class concerns. Inputting into architecture and technical direction in collaboration with Principal Engineers - making considered, well reasoned decisions on service boundaries, data design, messaging patterns, consistency guarantees and performance. Championing a high quality engineering culture - test coverage, peer review, CI/CD discipline via GitHub Actions, Infrastructure as Code, secure coding, observability and performance - aligned to the Reapit Global Technology Strategy, Reapit Connect and agentic tooling. Mentoring and up levelling engineers around you through pairing, PR review, architectural guidance and practical coaching on AI assisted development. Who we're looking for At Reapit, we prioritise hiring individuals who share our values and possess the right attitudes and behaviours for success. Whilst all the listed qualities are desirable, don't worry if you don't meet all of them, we'd still like to hear from you. A proven senior-to-staff-level backend engineer with deep, current expertise in C# and .NET Core 8/9 - you can architect and lead design of distributed REST API microservices at scale. Authority in AWS serverless architecture - Lambda first, with strong working knowledge of API Gateway, SQS, Step Functions, EventBridge and IAM, and a track record of shipping production workloads on this stack. Deep data expertise across Aurora RDS MySQL and DynamoDB - complex schema and access pattern design, query tuning, indexing, single table vs multi table trade offs, and a pragmatic view on consistency, scaling and cost. Proven track record designing event driven systems with SQS (and adjacent AWS messaging) - idempotency, ordering, retries, dead letter handling and operational robustness. Strong API design sensibility - versioning, documentation, throttling, backwards compatibility and an obsession with the developer experience of the services you own. A strong product brain. You're comfortable operating without a traditional Product Owner - partnering with BAs on high level problems, then making sensible product trade offs, prioritising ruthlessly and owning the solution through to delivery. Strong communication skills and comfortable with ad hoc client interaction - able to join a requirement or technical solutioning session, ask the right questions, and translate outcomes into shippable work. A proven track record with Claude Code and advanced agentic workflows - you can evidence shipping real work via multi-agent patterns, orchestrating sub agents, managing context, defining custom commands/skills and scaling AI assisted delivery across a team. Rigorous engineering standards - fluency with Git-based workflows, trunk-based development, CI/CD (ideally GitHub Actions), Infrastructure as Code (AWS CDK or Terraform), comprehensive testing (unit, integration and contract), and a genuine commitment to observability, performance and secure by default coding. Technical leadership without the title - a track record of lifting teams through pairing, mentoring, PR review and example, rather than through line management. A pragmatic, outcome oriented mindset - biased to shipping, comfortable with ambiguity, and able to make sensible calls on scope, technical debt and sequencing under time pressure. Nice to have: hands on experience with OpenSearch and/or AWS AppSync - both feature in our stack and would accelerate time to value, but neither is essential. What your impact and success looks like As a Backend Engineer we expect your success and impact over the stages of your contract with us to look something like this: Within 1 month Fully onboarded onto the Reapit stack - Reapit Connect, the relevant .NET services and AWS environments - shipped first production endpoints and / or services. Established trusted working relationships with the Director of Engineering, Principal Engineers, Business Analysts and the relevant squad. Configured Claude Code and our approved agentic tooling to our internal standards, and started running meaningful work through multi agent patterns. Built a clear, independent view of the target services, data model, database schemas, messaging topology and immediate delivery priorities - and surfaced any early risks or recommendations. Within 3 months Owning end-to-end delivery of substantive services - taking from BA-level problem statement through to production on Lambda, Aurora and DynamoDB, with you driving the product trade-offs as well as the engineering. Recognised as a go to technical voice within the squad - inputting into architectural decisions alongside Principal Engineers, raising the quality bar on PRs, and unblocking complex backend, data and messaging problems. Meaningfully influenced our wider engineering practice - patterns you've introduced for agentic delivery, Claude Code usage, serverless design or data modelling. Shipped APIs and services that are visibly well designed, well documented and performant - other engineers find them pleasant to consume, and they hold up under production load. Left a well documented, well tested, maintainable footprint - so that whether the contract is extended or handed over, the work continues to deliver value without you in the room. What's in it for you? We operate a Flexible Working Policy and there is no expectation around in-person attendance, beyond occasional ad hoc project meetings in our Solihull or London offices. You can expect an industry competitive day rate. Don't tick all the boxes? Neither do we We care about our industry and want it to become a more inclusive and diverse place to work. So, we're driven by hiring not only by experience and relevance for the role but by sharing our values and the right attitudes and behaviours for success.

We feel we have an empowering environment where everyone is supported and respected, and we want you to feel this too.
