Who Are We Looking For?

A Senior Software Engineer who ships reliable, scalable systems — and uses AI pragmatically to move faster. Strong fundamentals (design, data, testing), end-to-end ownership of complex work, and a bias for clear prompts, scoped context, and measurable results.

What You’ll Be Doing

As a Senior Software Engineer, you will:

🤖 Use AI agents for ideation, diffs, code generation and docs — and own the outcomes

🧩 Create and reuse task-focused agents/sub-agents with clear success criteria

🛡️ Configure and operate (or equivalents) to provide least-privilege, task-specific context and tools

⚙️ Design & build event-driven services that are resilient, modular, and easy to reason about (human & AI)

🔗 Define clean service boundaries & contracts to enable independent deployment

📈 Develop & optimise streaming and batch data pipelines; measure and improve performance

🔄 Own the full product development lifecycle: uncover problems, shape solutions, deliver working software, launch to users, and close the loop with real-world feedback

✅ Raise quality via TDD, comprehensive tests, CI/CD, and strong production observability

🤝 Partner with Product & Design to turn customer problems into simple, shippable solutions

🧑 🏫 Mentor teammates through reviews, pairing, and knowledge sharing; help set engineering standards

📣 Share your work proactively within Engineering and with the wider community

Who You Are

You’ll thrive in this role if you:

✅ Experience with event-driven architectures and distributed patterns

✅ Track record with high-volume data (streaming & batch) and performance tuning

✅ Hands-on with Node.js, Kafka, PostgreSQL, React, microservices

✅ Solid testing discipline (unit/integration/e2e) and observability skills

✅ Clear communication and documentation; you unblock others and land outcomes

✅ Practical use of AI coding agents (e.g., Cursor, Claude Code) for planning, implementation, refactors, and tests

🧩 Curious about or experienced in infrastructure engineering is a plus
