Job description

We're hiring a hands-on Lead Engineer to design, build, and ship product features across our Go microservices and modern React front-end.

You'll work directly with our engineering leadership, Head of Product, and designer, taking end-to-end ownership of complex problems while pushing the boundaries of how engineers leverage AI both in product and in their daily workflow.

This is a building-first role. We expect you to be delivering significant cross-stack features independently within your first two months.

What You’ll Be Doing

• Design and ship new features across our Go microservices and React (Remix) front-end
• Own complex problems end-to-end — from database design to user experience
• Collaborate with engineering leadership, PM, and designer to deliver high-impact product improvements
• Build internal tooling to accelerate the entire team

Infrastructure & Developer Experience (Secondary)

• Maintain and improve our Kubernetes (GKE) infrastructure
• Contribute to CI/CD, observability, and developer workflows
• Help optimize our AI-assisted development tooling and practices

Must-Haves

• Active AI tool usage — you're already coding with AI assistants daily (Cursor, Claude Code, etc.)
• 7+ years senior engineering experience with strong full-stack product development
• Formal or informal experience providing technical leadership
• Systems thinking and ability to navigate complex technical systems
• Proven track record of shipping products
• Go familiarity or strong experience with Java, Scala, C#, Rust, Python or TypeScript
• Modern React (Remix/react-router or similar frameworks)
• Some DevOps experience with production systems and deployment
• Strong written and verbal communication skills for remote, async-friendly setup
• Self-driven and able to work autonomously

Bonus

• Significant DevOps/Cloud experience (Google Cloud, Kubernetes, microservices)
• GraphQL API design in microservice environments
• Event-driven architectures (Kafka)
• Distributed database experience (Cassandra, ScyllaDB)
• TailwindCSS utility patterns

What We Offer

• £100k-£120k base + meaningful equity
• London-based, hybrid
• Direct influence at critical inflection point
• Work with experienced founders (CEO: 6x founder, ex-CPTO SuperAwesome acquired by Epic Games)
• Proven product-market fit, blue-chip clients
• Profitable, venture-backed, choosing our own path
