## About the Role

write code but builds systems. You are the right fit if you:* Are forward-thinking and keep current with rapid tech advancements.* Have realised that raw coding is becoming commoditised, and you now find your flow state in high-level architecture, managing agents, enforcing code quality, and doing more with less.* Dislike manual work that AI can solve and proactively automate your workflows.* Are driven by impact, thrive in an early-stage environment, and never say "that's not my job."* Are eager to learn, aware of your technical blind spots, and build greatcamaraderie with your team.Must-Haves (Non-Negotiable)* Polyglot Mindset: Our core backend is Java 21.
