Empower Your Career
We're seeking a
Senior Full Stack Engineer
to play a key role in delivering high-quality, scalable systems across our most important programmes.
This mandate focuses on building an ultra-fast, highly performant modern web application using
Next.js, React, TypeScript, and GraphQL
within a highly secure environment.
This role is hands-on and delivery-oriented, requiring true end-to-end ownership.
You will have the scope to heavily influence both frontend and backend architecture, establish performance baselines, and lead by example within our engineering teams.
We are looking for a highly proactive engineer who thrives when navigating legacy constraints and who takes the initiative to find solutions rather than waiting to be given the answer.
Key Responsibilities
End-to-End Architecture:
Design and build production-grade, highly performant systems across the entire stack using
TypeScript, React, Next.js, and Node.js
.
Proactive Problem Solving:
Take absolute ownership of technical challenges.
Autonomously investigate issues, propose robust solutions, and drive them to completion without waiting for detailed, top-down instructions.
Complex Integrations & Legacy Constraints:
Architect resilient software solutions that successfully navigate strict enterprise constraints,



including seamless integration with legacy systems and complex, disparate third-party APIs.
GraphQL Mastery:
Architect and implement robust
GraphQL
APIs on the backend (resolvers, schemas, query optimisation) and seamlessly consume them on the frontend with modern caching strategies.
High-Performance Frontend:
Ensure optimal Core Web Vitals and lightning-fast render times by leveraging advanced Next.js features (SSR, SSG, client-side routing).
Secure Development:
Architect full-stack solutions that adhere to the strictest security standards, working safely within a highly secure enterprise environment to protect sensitive data and prevent vulnerabilities at every layer.
Ecosystem Management:
Build and maintain systems within complex monorepo architectures, ensuring clean separation of concerns and shared tooling.
DevOps & Testing:
Develop and maintain CI/CD pipelines using GitHub Actions or TeamCity.
Implement robust full-stack test automation practices, including containerised workflows using Docker.
Cloud-Native Deployment:
Leverage AWS-native services to deploy reliable, scalable applications.
AI Tooling Adoption:
Champion the adoption of GenAI and agentic tools where they tangibly improve engineering productivity, code quality, or system capability.
What You Bring
Senior-Level Expertise:
Proven experience operating at a Senior Engineer level within modern,



high-performing engineering teams.
Self-Starter Mindset:
A highly proactive approach to engineering.
You are known for hunting down answers, researching architectural trade-offs independently, and bringing fully formed solutions to the table.
Constraint-Driven Design:
Demonstrated ability to design up-to-date software around legacy systems and execute highly complex API integrations securely and reliably.
Full-Stack TypeScript Mastery:
Deep, hands-on expertise writing production-grade
TypeScript
on both the client and the server.
Frontend Excellence:
Mandatory, proven experience building complex, high-performance applications using
React and Next.js
.
Backend & API Design:
Extensive commercial experience building scalable backend services in
Node.js
and designing/implementing
GraphQL
APIs from scratch.
Security & Performance:
A strong track record of building performant applications (optimising bundle sizes, rendering strategies, database queries) specifically within highly regulated or secure environments.
Infrastructure & CI/CD:
Experience deploying and operating workloads on AWS, managing CI/CD pipelines, and working with Docker.
AI Fluency:
Exposure to GenAI and agentic engineering tools, with a practical, delivery-focused mindset on how to use them safely.
What We Offer
Meaningful, hands-on engineering work across complex, enterprise-grade platforms.
Clear growth pathways from Senior to Staff and beyond.
A low-ceremony, delivery-focused environment that values engineers who proactively own outcomes.
Competitive remuneration and benefits.
The opportunity to work alongside highly experienced engineers on challenging, high-impact systems.
