Senior Software Engineer, Kaluza

• These are the practices and behaviours we see most in our top engineers and value deeply, but we don't expect everyone to tick every single box. If you're excited by the role and can see yourself thriving here, we’d love to hear from you
• Experience shipping production software: You have a depth of experience in either a front-end or back-end of a modern stack, and potentially an openness to stretch across both as you navigate our diverse ecosystem
• AI coding tools: You build with tools like Cursor or Claude Code, can walk us through work you’ve shipped this way and review AI output as rigorously as a colleague’s pull request
• Able to navigate a complex, high-stakes domain: You keep complex energy logic legible across microservices, knowing exactly when to use sync vs async to prevent cascading failures
• Cloud and operational ownership: You're comfortable deploying on major cloud platforms using shared tooling. You fully own your software in production, which includes participating in an out-of-hours on-call rota
• Strong product sense. You ask the “why” before building, and you can describe a time when user feedback or metrics changed what you shipped
• Clear written communication. You write specs, pull request descriptions and post-mortems with enough clarity and context that either a human teammate or an AI agent can immediately act on them
• A multiplier for your team: You mentor peers and proactively shape how the team works; introducing conventions, checks or shared context that makes everyone else’s output consistently better
• We want to meet people from all walks of life. The more inclusive we are, the better our work will be, and we recognise talent on merit and potential. If you’re excited about the role but don’t tick every box, we’d still love to hear from you

Desirable

• Reporting To: Software Engineering Manager
• You’ll join a technology community of product-focused and data-led product and platform engineers working at scale
• Ave a diverse ecosystem, spanning TypeScript on AWS, Go on GCP and Scala, we index on product-minded problem solving over language purity
• As a Senior Engineer you’ll own a slice of the product end-to-end, from design through to production, and you’ll build AI coding agents as your default. We’re looking for someone whose judgement is worth more than their typing speed
• From your first day you’ll have paid access to Claude Code, with a budget we don’t ration, and access to the systems you need through MCP. Our tools and conventions evolve quickly, and you’ll directly impact how we build from here
