Job Description:

Senior Software Engineer

Full Remote as long as UK based

We're looking for a Senior Software Engineer to join a fast-moving team building tools used by thousands of real-world users. You'll collaborate closely with Product, Design, and Customer Success to solve meaningful problems, not just tick technical boxes. You'll mentor others, contribute to architectural decisions, and engage directly with customers to make sure what you're building actually works for them.

What You’ll Be Doing

• Writing production-grade software in Ruby on Rails and React Native
• Leading on technical and architectural decisions across the stack
• Collaborating cross-functionally with Product, Design, and Customer Success
• Mentoring junior engineers and reviewing code with kindness and clarity
• Engaging with customers to understand pain points and improve the product
• Improving developer workflows, testing practices, and engineering processes

You’ll Thrive Here If You...

• Have deep experience in Ruby on Rails
• Are confident with React Native or React.js
• Communicate complex ideas simply and clearly — both in code and conversation
• Value user needs over technical perfection
• Enjoy mentoring, sharing knowledge, and working in an open, feedback-driven culture
• Want to ship frequently and iterate fast — we’ve built great tools to support this

Why Join

• Autonomy: You’ll have real input into what we build, not just how
• Impact: Your code will ship to real users — often within hours
• Culture: Pragmatic, friendly, and focused on collaboration and learning
• Growth: We support personal development and welcome your ideas at every level

Interested?

Apply now and let’s talk. Even if you’re not sure you meet every requirement if this sounds like a fit, we’d love to hear from you.

Please Note: You must be based in the UK with full working rights.
