Project focus

You’ll join an established product engineering team working on a live employee benefits platform, splitting your time roughly evenly between Python backend and React frontend. The work centres on the self-service customer portal and internal tools: improving existing features, shipping new ones end to end, building REST APIs and partner integrations, and keeping the platform fast and reliable.
