We are early-stage, fully funded, and moving fast. We are building something that genuinely matters in a market that has not changed in decades.
The Role
We are looking for a Backend Developer to help build the systems that power Hyalli. You will work closely with our lead developer and founding team to design, build, and maintain the backend infrastructure behind our web and mobile platform. This is a hands-on role.

- Modelling and managing data — including personal data — in a way that respects user privacy and meets GDPR requirements
- Contributing to technical decisions around stack, infrastructure, architecture, and deployment
- Writing clean, tested, maintainable code
- Iterating quickly based on real user feedback
What We Are Looking For
- Proven experience with server-side languages — C#, Python, Java, Node.js, or similar
- Strong knowledge of RESTful API development (ASP.NET Web API or equivalent)
- Solid understanding of database design — SQL, T-SQL, PL/SQL, Entity Framework or similar ORM tools
- Working knowledge of GDPR-compliant frameworks and data protection principles
- Experience with Agile development environments
- Someone who writes code they would be happy to come back to in six months
Nice to have: experience in proptech, fintech, or consumer-facing platforms
