Senior Software Engineer

Senior Software Engineer – Backend (TypeScript / Node.js)

Remote (UK)

Circa £150,000

This opportunity is with a growing B2B technology company building backend-heavy products used by enterprise customers in a regulated space. The platform focuses on reliability, data correctness, and operational robustness.

The business is continuing to scale its engineering function and is investing in strengthening the foundations of its backend systems as both the product and customer base grow.

The Role:

They're looking for a Senior Backend Software Engineer to join one of their product engineering teams, with a focus on building and running services in TypeScript / Node.js.

This is a hands-on role working on core backend services that underpin the product. You'll take ownership of meaningful technical areas, contribute to architectural decisions, and help raise engineering standards as the team grows.

What You'll Be Doing:

• Building and operating backend services in TypeScript / Node.js
• Owning services end-to-end, including production support
• Working with data-heavy systems where correctness and reliability matter
• Integrating with third-party APIs and external systems
• Improving performance, observability, and resilience
• Contributing to system design and architectural decisions
• Helping set and uphold engineering best practices, and acting as a senior presence in the team

What They're Looking For

• Strong backend engineering experience with TypeScript / Node.js
• Experience working with modern backend frameworks and production databases
• Familiarity with cloud-native environments (AWS or similar), containers (Docker), and orchestration (e.g. Kubernetes)
• Experience operating and improving production systems, not just building features
• A quality-focused mindset and a clear understanding of what "good" looks like in backend engineering
• Comfort working in complex, evolving systems with real-world reliability requirements

Industry background isn't the priority — they're looking for solid senior backend engineers who care about building dependable systems.

Why Consider It?

• A chance to work on meaningful backend problems
• Exposure to complex data flows and reliability challenges at scale
• Real influence over how systems are built, operated, and improved
• An environment that values ownership, pragmatism, and engineering quality
