Senior Software Engineer

Full Stack - Ruby on Rails, React

Up to £120k DOE

Fully Remote - must be UK based

We're looking for a senior, hands-on engineer who still loves being deep in the code, but is ready to play a bigger role in shaping how a product and engineering team evolves.

This is a fully hands-on role where you'll spend the majority of your time building and shipping software in Ruby on Rails and React, while also acting as a technical role model for the team. You'll work closely with the Head of Engineering on architectural direction, help raise the bar on engineering quality, and mentor other engineers through example.

What you'll be doing

Designing, building, and maintaining high‑quality software across the stack, primarily in Ruby on Rails and React
Taking a lead role in technical and architectural decisions, partnering closely with the Head of Engineering
Staying deeply hands‑on while setting patterns and standards others can follow
Mentoring and supporting engineers across different levels through code reviews, pairing, and informal coaching
Collaborating closely with Product and Design to shape solutions, not just implement tickets
Championing testing, clean code, and maintainable systems
Continuously improving engineering practices, tooling, and ways of working

What we're looking for

Significant experience building and running production systems with Ruby on Rails
Strong experience with React and modern frontend practices
A track record of making sensible architectural decisions in growing codebases
Someone who enjoys being a technical leader without stepping away from hands‑on work
Clear communicator who can explain trade‑offs and decisions to both engineers and non‑engineers
A pragmatic mindset: focused on solving user problems rather than chasing theoretical perfection

What's in it for you

Salary up to £120,000, depending on experience
Fully remote role, UK‑based
A senior position with real influence over architecture and technical direction
The chance to work in a small, experienced team where quality and autonomy are valued
Space to mentor others while continuing to grow technically yourself

We're proud to be an equal opportunities employer and encourage applications from all backgrounds.
