Dose Senior Developer Full-time Stockport (Thursdays) / Remote Competitive, depending on experience About Naturecan Naturecan is a fast-growing, multi-market health and wellness company operating across e-commerce, pharmacy, and clinical healthcare. We run regulated operations in the UK, Germany, and beyond - across brands including Naturecan, Mycannabis, and Dose. Our technology team sits at the heart of that growth. We build and maintain the platforms that underpin every part of the business - and we're scaling fast. About the Dose Platform Dose is our UK medical cannabis clinic - CQC-registered and GPhC-registered pharmacy, pre-launch, and built to deliver a full end-to-end digital treatment pathway. We are now launching a brand-new, world-class digital platform to power the full patient treatment pathway: from initial consultation and prescribing through to dispensing, fulfilment, and ongoing care. This is a greenfield build with a clear brief: scalable, secure, and built to a standard that can expand across EU and global markets. We are at a pivotal moment, and this role sits at the heart of it. The Role We are looking for an experienced Senior Developer to join a small, high calibre engineering team and help architect and build the Dose platform from the ground up. You will work closely with the IT Director, lead developer, clinical stakeholders, and product management to deliver a product that meets the rigorous demands of a regulated healthcare environment - while being fast, elegant, and built to last. This is not a ticket grinding role. We want someone who takes ownership, thinks about the wider system, and cares about the quality of what they ship. What You'll Do Architect and build core features of the Dose platform - from patient onboarding through to prescription management and fulfilment integration. Work across the full stack, with a focus on backend services, APIs, and secure data handling in a regulated environment. Collaborate with the IT Director and lead developer on system design, code review, and technical decision making. Contribute to the establishment of engineering standards, CI/CD pipelines, and testing frameworks from an early stage. Integrate with third party clinical systems, pharmacy platforms, and payment providers. Ensure the platform is built to meet CQC, GDPR, and relevant healthcare compliance requirements. Participate in sprint planning, retrospectives, and cross functional delivery discussions. Skills & Experience We're looking for someone with most of the following - you don't need to tick every box: 5+ years of professional software development experience, with strong backend skills in Bun.js (or Node.js), TypeScript, React or comparable JavaScript libraries. Experience designing and building RESTful APIs and microservices at scale. Solid understanding of relational databases (PostgreSQL or similar) and data modelling. Familiarity with cloud infrastructure - GCP, AWS - and infrastructure as code practices. Experience with CI/CD tooling (GitHub Actions or similar) and automated testing. Strong knowledge of security best practices, particularly around authentication, authorisation, and sensitive data handling. Experience working in regulated or compliance heavy environments (healthcare, fintech, or similar) is a strong plus. Comfortable working in small teams where ownership and initiative matter as much as technical skill. Familiarity with AI assisted development workflows - using tools for ticket creation, code assistance, documentation, and engineering efficiency. Ability to take end to end ownership of features - driving work from technical design through to production without needing to be managed at every step. UI experience is a plus. Interview Process Initial call (30 mins) Technical review - (1 hour) Team meet - working practices, Q&A Offer Dose is part of the Naturecan group. We are committed to building a diverse and inclusive team and welcome applications from all backgrounds. What We Offer Salary: Competitive, depending on experience Location: Stockport office (Thursdays) - open to fully remote for the right candidate Pension: Company pension scheme Health: Private health insurance Staff discount: Naturecan group product discount AI Tooling: Claude Enterprise access across the team - AI assisted development workflows embedded in how we work Culture: Small team, big ambition - you'll have genuine ownership and direct access to decision makers Process: Two week sprints, retrospectives, pair working practices, Q&A Offer: Meaningful equity conversation for the right candidate

About HelmGuard We're building agent-native risk infrastructure: risk management and trust building, delivered by AI agents, for a world increasingly run by them. As more decisions and transactions run through agents, the volume of risk to manage and trust to establish is growing very fast. Today both functions are fragmented, split across internal teams, point products, and outside consultants, and rebuilt from scratch whenever someone needs an answer. HelmGuard brings them onto one platform and runs them continuously: our agents sit on top of proprietary data and reassess as conditions change, rather than at fixed checkpoints. So our customers spend their time deciding and acting on what matters, not assembling the evidence to get there. Hundreds of billions of dollars are spent across risk management and trust building annually. These funds are going to be reallocated to agent-native solutions in the next five years, and we will capture that spend. We've grown to seven-figure revenue within months of product launch, on the back of multi-year contracts with leading enterprises in financial services, regulated technology, and healthcare. Our founders come from Palantir and academic institutions: Oxford, Stanford, and ETH. We're backed by leading UK and US institutional investors and exceptions angels from Meta, Isomorphic Labs, Palantir, SpaceXAI, and more. We're hiring across founding-team roles for people who want outsize impact, the influence over direction and culture that comes only from joining this early, and pre-Series A equity upside. Your Impact In this role, you'll be the critical node for our platform's adoption. Once a customer signs, it's on you to make them successful. You'll expand the relationship, and turn each account into a reference customer that defines how we sell to everyone who comes after. The customers you make successful in year one become the basis of everything we build in year three. The Role As a Forward Deployed Engineer (FDE), you own our enterprise accounts end-to-end and get your hands dirty with related development. You're the first person our customers call and their trusted counterpart. You sit across the table from CSOs, VPs of Risk, heads of compliance, and you turn their messiest workflows into something that runs on our platform. Our platform is user-friendly, but we find great value in staying close to customers and understanding their needs. Expect roughly one to two customer meetings per week per account, plus the async work around it, driving adoption, configuring the platform, chasing requirements, helping decide what features to implement and implementing them, keeping things moving. You'll own a dozen plus accounts at any given time. This is the closest thing we have to a founding-team role outside the founders. You'll be partnering directly with our CTO to help shape what the company becomes. What You Will Do Own strategic accounts: adoption, expansion, renewal, the whole thing Run weekly working sessions with senior stakeholders; drive the agenda, close the loop Configure the platform to fit each customer's reality Manage the async cadence: emails, follow-ups, status updates, internal escalations Translate customer needs into prioritized product feedback that actually changes the roadmap Hold your own in procurement, security review, and contract conversations Ship code with Claude Code. When a customer needs a UI fix, a small feature, or a bug squashed, you do it. You don't need to be an engineer today, but you need to want to ship by month three. We'll teach you. You Probably Have 2-5 years of experience doing something hard and impressive Real commercial instinct: you've sold, negotiated, or owned customer outcomes in a way you can point to Comfort being the single point of accountability when something is on fire Bonus Solutions architect, deployment strategist, customer engineer, or similar background at a technical enterprise company Experience at a Series A/B enterprise startup (GRC, cyber or legal tech in particular) Background in risk, compliance, or financial services Experience in software development Culture and Values We value a diversity of perspectives and experiences. We also hold a small set of core beliefs that reflect how we operate, and share them transparently with candidates so the fit is clear from the outset. Put Customers First. Our customers buy outcomes from us, not features. We judge every decision by whether it delivers on that promise. Take Ownership. Founding-stage means problems don't come pre-scoped. You see something that needs doing, scope it, ship it, own the outcome. We expect this from everyone, and provide you the backing to execute on it. Work Hard, With Gratitude. This is the most consequential window for building enterprise software in a generation. We work hard because the opportunity is rare, and we do it with gratitude for the moment, for the people we get to build it with, and for the customers willing to bet on us this early. Say the Silly Thing. The best ideas usually start out sounding half-baked, so we'd rather you say the silly thing than sit on it. We want you opinionated and willing to argue, and just as willing to change your mind when someone makes a better case. Disagreement here is a contribution, not a risk. Working at HelmGuard Location. King's Cross, London (Gridiron building). We're built around in-person collaboration and expect most days to be in-office, with flexibility for the days that need it. Compensation. Top decile for the London market, with meaningful EMI-eligible options. Perks. Daily team lunch and specialty coffee, a roof terrace overlooking King's Cross, on-site showers for those who enjoy active commuting, and serious per-engineer AI tooling and API budgets. Tech Stack. TypeScript, Node.js, React, Tailwind, OpenAPI, Express, Azure (Container Apps, Service Bus, Front Door, Entra ID), Postgres, Terraform, GitHub Actions, Docker. Anthropic-first AI with in-house evals and scaffolding. Claude Code throughout.
