Job description

Senior Full Stack Developer -TypeScript / Node.js / React

We're looking for a talented Senior Full Stack Developer with a strong backend focus to join a growing engineering team. This isn't a role for someone who simply works with React and Node.js—it's an opportunity for an engineer who genuinely understands how modern web applications and cloud infrastructure work from end to end.

You'll be involved in maintaining and improving existing production systems, supporting day-to-day engineering activities, and contributing to the development of a new platform. The role offers a mix of complex technical challenges alongside essential business-critical work, requiring someone who takes pride in ownership and delivery.

What You'll Be Doing

• Maintaining and enhancing existing production applications.


• Contributing to the design and development of a new platform.


• Building and supporting scalable backend services and APIs.


• Investigating, troubleshooting, and resolving issues across the full stack.


• Working closely with teammates through collaboration and paired programming.


• Improving system performance, reliability, and scalability.


• Supporting infrastructure and deployment processes within AWS.


• Taking ownership of tasks and proactively identifying areas for improvement.

What We're Looking For

We're interested in engineers who enjoy understanding how things work beneath the surface.

You'll ideally have experience with:

Core Technologies

• TypeScript


• Node.js


• React


• JavaScript

Cloud & Infrastructure

• AWS


• Infrastructure as Code (CloudFormation or similar)


• ECS / Fargate


• Lambda


• API Gateway


• SQS


• DynamoDB


• PostgreSQL


• Redis / ElastiCache


• Load Balancers (ALB/NLB)

Engineering Fundamentals

• HTTP and networking concepts


• Caching strategies


• Linux environments


• Git (including rebasing, merge strategies, and branching workflows)


• Testing and debugging


• Performance optimisation and scalability

What Makes Someone Successful Here?

You'll thrive if you:

• Have strong problem-solving skills and can debug independently.


• Enjoy understanding systems end-to-end, from frontend through to infrastructure.


• Are comfortable working across different areas of a technology stack.


• Take ownership and proactively improve systems without needing constant direction.


• Enjoy learning and developing your skills.


• Are a team player with strong communication skills.


• Leave your ego at the door and focus on building great software.

Nice to Have

• Experience with event-driven architectures.


• Serverless development experience.


• Exposure to scaling high-traffic applications.


• Experience working within small, fast-moving engineering teams.

Why Join?

This is an opportunity to join a close-knit engineering team where you'll have genuine ownership, exposure to modern cloud technologies, and the chance to make a significant impact on products used by real customers. You'll work alongside experienced engineers who value collaboration, continuous learning, and technical excellence.

We're much more interested in mindset, problem-solving ability, and engineering depth than ticking every box on a checklist. If you're passionate about software engineering and enjoy learning, we'd love to hear from you.
