You’ll likely be a good fit if you bring: Strong TypeScript and Angular experience Genuine Java strength, especially around API integrations Comfort working across front end, back end and data Strong product instinct and the ability to ask why something should be built, not just how Practical experience or strong fluency with AI coding tools Clear communication with product, client and engineering stakeholders Good judgement around quality, maintainability and long-term stability Ability to own work end to end without needing every next step defined Tech stack The core stack includes: TypeScript with Angular Java, with some Python Google Firebase PostgreSQL Google Cloud Storage You do not need to have used every part of the stack, but strong Java, modern TypeScript and Angular will set you up well. Working arrangement This is a remote New Zealand-based contract role. The client and wider team are based in the United States, so some daily overlap with the US west coast may be needed. The exact working pattern will be agreed together. The initial engagement is expected to run for around four months, with the possibility of extension if things go well.
