In this role, you'll go beyond writing excellent code; you'll shape our technical direction, elevate our engineering practices, and mentor engineers across the organisation to help the company deliver the next iterations of our product, the BUX App.
To do this, you will have the help of other very experienced colleagues, the freedom to brainstorm and suggest new ideas, and the time to execute those ideas in a high-quality way.

Take project requirements, design solutions, and document them in RFCs (Request for Comments)
Follow, learn, apply, and advocate for modern software development practices across the team and organisation
Analyse technical challenges (e.g., scalability), raise awareness of technical debt, and proactively address system issues before they impact users
Help grow the technical skills of less experienced colleagues and collaborate across teams on planning and execution of broader impact projects
Discuss technical solutions with Product Owners, support colleagues with complex problems, and diagnose and resolve live user issues or monitoring alerts in a thought-out, planned, and organised manner

Excellent command of Git and collaborative workflows (e.g., GitFlow)
Excellent knowledge of core system-design concepts and common microservices design trade-offs
Ability to own, be responsible and accountable for the success of projects where own direct code contribution is combined with mentoring of less experienced colleagues
Excellent command of Java, Kotlin and the Spring framework ecosystem
Experience working with transactional Kafka and event-sourcing architectures
A solid understanding and working knowledge of GCP (with focus on Kubernetes)
