✔️ High-impact work in a fast-growing startup

✔️ Strong engineering culture – collaborative, pragmatic, product-focused

✔️ Solid object-oriented design & scalable architecture skills

✔️ Experience working across the full stack in production

✔️ Leadership experience – mentoring, managing, growing engineers

✔️ Confident making technical decisions & trade-offs


✨ Nice to Have

➕ Experience with Golang (or strong desire to move into it)

➕ Legacy system modernisation / migration

➕ Kubernetes / cloud-native experience

➕ High-throughput, data-heavy systems

➕ Experience in regulated domains (e.g. healthcare)
