Job Description:

Senior & Staff Software Engineers – TypeScript, AWS, Serverless | Backed by the UK’s Top Subscription Business

We’re hiring Senior and Staff Engineers for one of the most exciting start-ups in the UK tech scene—backed by the UK’s most successful subscription company (yes, the one from Dragons’ Den that became the most profitable business to ever walk away without an offer!).

Now led by a CTO who is ex-Palantir, this well-funded team is building a next-gen B2B platform that’s set to revolutionise subscription technology. Their mission? Help businesses deeply understand their customers, not just rely on one-size-fits-all tools.

Why Join?

• Startup energy, zero investor pressure: With strong internal backing, they’re free to prioritise quality over quick wins.
• Early team opportunity: Join as they enter a major growth phase and shape the future of the platform.
• Tech-forward environment: Build scalable, event-driven systems using cutting-edge tools.

Tech Stack & What They’re Looking For:

• Strong hands-on experience with React and TypeScript but other stacks will be considered
• Deep familiarity with AWS (Lambda, DynamoDB, SQS, SNS, ECS)
• Proven ability to take product requirements and deliver production-ready systems
• Background in event-driven architecture and RESTful API design

Location: London (Hybrid flexibility available)

If you’re passionate about building high-impact systems and want to be part of a mission-driven, product-focused team, we’d love to hear from you.
