Senior Backend Engineer

While your primary focus will be strengthening our backend systems, we're not looking for someone who only wants to live in that layer. At Onetrace, engineers are expected to think and work like full stack product engineers - flexible, collaborative, and willing to jump into whichever part of the stack will best solve the problem. That might mean refining APIs and scaling services one day, and the next day pairing with a frontend engineer or tweaking infrastructure to remove a bottleneck. If you only want to stay narrowly in the backend, this role isn't the right fit. But if you enjoy seeing the bigger picture and contributing across boundaries, you'll feel right at home., As a Senior Backend Engineer at Onetrace, you'll strengthen our backend systems and empower the entire engineering team to build with confidence and velocity. You'll tackle technical debt, evolve our architecture for scale, and create well-documented patterns and tooling that make our platform more resilient, performant, and developer-friendly. This isn't a role where you "own the backend" in isolation. You'll collaborate across the stack, working closely with other engineers, product managers, and designers to ensure our platform foundations enable great product experiences. From refining API design to optimising performance and observability, you'll be the driving force behind the systems that keep Onetrace running smoothly and growing fast.

WHAT YOU'LL DO

• Design, build, and maintain backend services using Node.js and TypeScript
• Evolve our architecture for scalability, performance, and maintainability
• Refactor and modernise legacy systems to reduce technical debt
• Design and enhance RESTful APIs, ensuring consistency, security, and clear documentation
• Integrate with both internal and external services, building reliable, well-tested connections
• Implement and improve observability: logging, metrics, monitoring, and alerting
• Optimise database performance across MongoDB and SQL-based systems
• Introduce and maintain patterns, tooling, and frameworks that improve developer experience
• Collaborate cross-functionally to translate product requirements into technical solutions
• Mentor engineers through code reviews, pairing, and knowledge-sharing sessions

Good communication skills
