Senior Fullstack Engineer

We're looking for a senior engineer to join our small, collaborative engineering team. This is a hands-on role where you'll be designing and building the systems that power our platform, while helping set the technical direction for how we grow.

You'll be a go-to person for architectural decisions and a mentor to the engineers around you. We're after someone who's as comfortable pairing with a junior developer as they are making calls on system design. You don't need to have used every part of our stack. What matters most is that you're experienced, pick things up quickly, and enjoy getting stuck into hard problems.

What You'll Be Working With

Our stack includes TypeScript, React, and React Query on the frontend, with AWS Lambda, Node.js, and PostgreSQL on the backend, running on AWS cloud infrastructure. You'll work across both sides of the stack, so comfort in either direction matters.

We care more about how you think and approach problems than whether you've used every tool in this list before.

What You'll Be Doing

Technical Leadership You'll play a key role in shaping how we build things. That means owning architectural decisions, identifying the right trade-offs between speed and sustainability, and making sure our systems are reliable and performant. You'll contribute to our product roadmap from a technical perspective and help the team navigate complex dependencies and risks.

Building This isn't a role where you stop writing code. You'll be hands-on daily, delivering high-quality solutions across the stack, improving our development workflows, and tackling the harder problems that come with a growing platform.

Growing the Team You'll mentor engineers across the team, helping them develop their skills and confidence. You'll also be involved in recruitment, from screening candidates and reviewing code challenges to helping shape how we onboard new joiners.

Communicating You'll regularly translate technical concepts for non-technical stakeholders. Being able to explain the "why" behind decisions clearly and calmly is a big part of this role., Flexible hybrid working. Two days a week in our Central London office in Farringdon, the rest from wherever works for you.

No out-of-hours support. We believe great work happens when people have balance.

Real influence. You'll have direct input into architectural decisions and the technical direction of a growing SaaS platform.

A learning culture. Dedicated time and support for developing new skills, working with modern cloud-native technologies.

A collaborative team. We genuinely enjoy working together and supporting each other's growth.

Do you have experience in TypeScript?, You'll likely have:

• Strong commercial experience designing and building systems across the full stack in production
• Deep experience with TypeScript, Node.js, SQL, and relational databases
• Solid experience with React or similar frontend frameworks
• Experience with cloud infrastructure, ideally AWS and serverless architectures
• A track record leading the delivery of complex technical projects and bringing others along with you
• A thoughtful approach to system design, making pragmatic choices that balance quality with pace
• The ability to communicate well and work effectively across different disciplines

It'd be great if you have, but it's not essential:

• Experience building or scaling SaaS products
• Familiarity with event-driven architectures
• A background working with integration-heavy platforms
• An interest in security best practices

We're more interested in how you approach problems than how long you've been doing it.
