What you’ll be doing

Reporting to the Director of Engineering, you'll operate as a highly senior technically hands-on engineer, embedded into a squad and frequently working Forward Deployed - direct with clients to understand, shape and ship solutions to their workflows.

You'll be expected to own outcomes end-to-end across the stack.

• Architecting, building and shipping complex, high-performance Full Stack Type Script applications across React front-ends and with some BFF Node back-end work, setting the technical bar for the squad and owning delivery of substantive feature sets end-to-end.
• Operating as a Forward Deployed Engineer - sitting shoulder-to-shoulder with clients to elicit requirements, shape solutions, prototype in the room and translate messy real-world workflows into production-grade software.
• 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.
• Interpreting our design system to craft beautiful, highly interactive UX workflows from low-fidelity inputs - you don't wait for polished Figma to produce polished UI.
• Inputting into architecture and technical direction in collaboration with Principal Engineers - making considered, well-reasoned decisions on patterns, frameworks, state management, API design and performance.
• Championing a high-quality engineering culture - test coverage, peer review, CI/CD discipline via Git Hub Actions, secure coding, accessibility (WCAG) and performance - aligned to the Reapit Global Technology Strategy, Reapit Connect, Elements, Design System 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 Full Stack Engineer with deep, current expertise in Type Script, React and Node - you can reason about and build across the entire stack, from database and API design through to DOM and UX performance.
• Authority in React and the modern front-end stack - component-driven architecture, design systems, advanced state management (Redux Toolkit, Zustand, Tan Stack Query or Apollo), modern toolchains (Vite, ESBuild) and package managers (pnpm/yarn/npm).
• Strong Node. js back-end skills - RESTful and Graph QL API design, integration patterns, relational and No SQL data modelling, and a practical understanding of deploying into modern cloud and serverless environments (AWS and Cloud Flare preferred).
• Exceptional communication - genuinely client-ready.

You've operated as a Forward Deployed Engineer or in comparable client-facing roles, and you can run a discovery session, push back politely on a bad requirement, and turn a whiteboard conversation into shippable code.

• 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.

• A keen eye for design. You can interpret a design system and produce beautiful, intuitive, highly interactive UX workflows without needing high-fidelity mock-ups handed to you.
• 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.

This is non-negotiable.

• Rigorous engineering standards - fluency with Git-based workflows, trunk-based development, CI/CD (ideally Git Hub Actions), comprehensive testing (Jest, React Testing Library, Playwright), and a genuine commitment to accessibility, 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.
• What your impact and success looks like

As a Full Stack 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, Elements, the Design System and other tooling and the relevant product codebases - with a working local development environment and first pull requests merged.
• Established trusted working relationships with the VP of Engineering, Principal Engineers, Business Analysts, Design and the relevant squad, plus initial exposure to the client(s) you'll be working with directly.
• Configured Claude Code and our approved agentic tooling to our internal standards and started running meaningful work through multi-agent patterns - not just using an assistant, but orchestrating it.
• Built a clear, independent view of the target problem space, the existing architecture and the immediate delivery priorities - and surfaced any early risks or recommendations.

Within 3 months

• Owning end-to-end delivery of substantive feature sets and client-facing workflows - taking from BA-level problem statement through to production, with you driving the product trade-offs as well as the engineering.
• Running productive, confidence-inspiring client sessions in a Forward Deployed capacity - eliciting real workflow requirements, prototyping in-session, and translating outcomes into shippable work.
• Meaningfully influenced our wider engineering practice - patterns you've introduced for agentic delivery, Claude Code usage, front-end architecture or UX craft are being adopted by other squads, not just yours.
• Shipped user-facing UX that is visibly on-brand, accessible and polished - interpreted from the design system with minimal input from Design.
• 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 front-end and back-end problems.
• 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.
