As a Senior Software Engineer on the Financial Platform team, you'll help build the systems that ensure Perk's financial data is accurate, traceable, and audit ready. You'll work on expanding the platform to support increasingly complex financial flows, with a focus on building reliable reconciliation and reporting systems that operate automatically and at scale. Rather than applying short term fixes, you'll design and implement durable solutions that improve the integrity and transparency of our financial infrastructure. You'll also help translate and untangle complex business logic across our ERP integrations, ensuring every transaction moving through Perk is correctly represented across systems. Through thoughtful engineering practices, strong ownership, and a focus on auditability, you'll contribute to a codebase that gives Finance and the broader business confidence in the numbers behind the platform. Are you a Software Engineer who thrives on real ownership? At Perk, we know that we feel most fulfilled when we can own the problem and the solution. This means taking responsibility for the entire lifecycle of a feature, from being part in understanding what our customers pains are with our product team, design documents, coding to deployment, and measuring impact. You will see how your technical decisions move the needle for our customers daily. We prioritize autonomy and pragmatism, giving you the space to solve complex problems without unnecessary friction. Engineering excellence here is measured by the reliability and simplicity of the systems you build to power a global platform. How we work At Perk, we believe the best work happens when great people come together in small teams, with a shared sense of purpose.

Each team to decide how to contribute to Perk's company goals. We care about impact, and we trust our people to deliver it. AI at Perk AI is embedded in how we work and what we build. On the engineering side, it spans the whole workflow: our Notion, Jira, GitHub and Slack are AI connected so you get up to speed fast, and day to day it helps with specifying features, writing and reviewing code, and automated AI PR review on every pull request. When something goes wrong in production, AI surfaces context across systems quickly. We also embrace agentic coding, using AI as an active collaborator, not just a prompt by prompt co pilot. We expect candidates to use AI tools in our coding interviews. The bar is understanding your code and owning what you produce. That reflects how we work every day. Some examples of what it means to be a Senior at Perk Shape the bigger picture. You won't just build features, you'll refine the what to build and why.

Whether it's coordinating a cross squad initiative, contributing to one of our engineering guilds (where engineers from different teams align on shared technical topics), or pairing with architects on solution discovery, you'll operate comfortably beyond your immediate team. Raise the bar for everyone around you. Senior engineers at Perk are mentors, coaches, and bar raisers. You'll support less experienced colleagues through direct mentorship, thoughtful feedback during reviews, and by modelling what great engineering looks like in practice. You'll help Engineering Managers understand where the team needs to grow technically, and you'll use spaces like guild meetings, design doc reviews, and pairing sessions to lift the overall standard.

Senior Software Engineer Location: London (flexible working with 3 days per week regularly expected in office) Job Type: Full-time Salary & equity: £100k+ Tech Stack: React, Typescript, Python, C#, Azure Must-Haves: Experience: 8+ years, including a track record of shipping production systems Back-end experience - ideally Node.js/TypeScript in a production API context and comfortable reading across other languages (C#, Python) Solid grasp of distributed systems fundamentals: async queues, event-driven workflows Track record of hiring and growing engineerings Comfortable in a startup environment where you're building the process alongside the product What will make your CV stand out: Experience with LLM/RAG pipelines in production (embeddings, vector search, retrieval quality measurement) Familiarity with Autodesk Platform Services / AEC data formats (IFC, Revit, ETABS, SAFE, or similar) Experience with Windows desktop application development (.NET / WPF / native integrations) Background in construction, structural engineering software, or document-intensive vertical SaaS Knowledge of graph-based data models, entity resolution, or knowledge graph tooling Having said that, don't worry too much about having experience with the specific tech stack - we are generally looking for people with strong core engineering skills and principles. The team are polyglots who believe specific technologies are just tools for tackling problems. The Company Structural engineering firms need effective design change management to avoid costly delays and manual design change propagation. Structural engineers work across a fragmented ecosystem of tools with no shared source of truth - ETABS models, SAFE analyses, Autodesk drawings, Excel specs, PDFs, emails. Bite is building an effective automated design change management product for structural engineering firms preventing costly delays, manual design change propagation, and errors. Our platform does two things that today require weeks of manual work: natural-language search across a project's entire file ecosystem, and cross-file impact detection ("I changed Column C7 in the structural model - what drawings, schedules, and specs are now out of date?"). Both are powered by a single underlying engineering-knowledge graph built on content-addressed file storage, per-file structured extraction, and a canonical entity resolver that unifies concepts across file formats. The Role You'll be one of the first engineering hires. You'll work directly with the founders across the full stack: a Node/TypeScript backend API, a React frontend, a C#/WPF Windows desktop connector, and Python ML/RAG workers. The codebase is in production and serves paying customers. You'll own significant parts of it, drive the architecture of the entity-resolution layer that everything else depends on, develop contracts between our services and eventually help hire and mentor the team that grows around you. This is an early role at a really exciting company with everything that implies - equity, influence over the technical direction, and the kind of hard problems that don't exist at bigger companies. What You'll Own: Ship features across the full stack. The platform is polyglot by design - you don't need to be expert in every layer, but you need to be comfortable moving across them. Strong in at least one of (but comfortable reading the other): Node.js/TypeScript backend Python async/ML pipelines Experience designing and evolving APIs and async event-driven systems (queues, workers, content-addressed storage) The instinct to keep things simple under pressure Comfortable having high ownership and autonomy. This is a very hands-on, delivery-focused role in a start-up environment. Because of this, there are always times when we need to come up with a short-term tactical solution to deliver something a little quicker than we would like. You will have a strong focus on code quality but also on flexibility and pragmatically paying off tech debt. We believe passionately in thorough automated testing so, whilst we don't necessarily care about strict TDD practice (i.e. tests DRIVING the development - written first), every PR must have the appropriate E2E tests, unit tests or eval harnesses. We own and have responsibility for the entire platform - its deployment and its reliability - so we also completely control our own CI and CD processes. The team is an autonomous and empowered multi-disciplinary one. Hiring Process We have a culture of respecting people's time and we know you'll have loads of other options, therefore we have a quick turnaround time and will let you know as soon as we can after each stage. Ask ANYTHING. The whole process is as much about making sure we're a fit for you as much as the other way around. Initial screening call (5 mins) Call with the VP of Engineering where you'll show us some of your code (30 mins) Pair with and get to know a member of our engineering team (1-2 hours) Reference checks + offer Must Haves Good communication skills - we are constantly communicating in very technical language to each other one minute; semi-technical language to (for e.g) the product manager the next; and in layman's terms to non-technical people the next. We value clarity above speed. Strong core engineering skills - we are generally looking for strong engineers with experience building reliable systems and taking responsibility for them, not necessarily people with a lot of (or any!) experience in our specific tech stack. Kindness, curiosity, optimism & drive - we, as a team and as a company, believe in being kind over being nice. We are constantly giving and receiving constructive feedback and we are always trying to be empathetic. We're all growing together and on a mission to create something bigger than ourselves that will leave a mark. We have to be optimistic when we hit inevitable roadblocks, curious about everything, and driven to be at the forefront of creating new products and change.
