* Developing, testing, and deploying backend services and APIs (Python preferred, e.g. Django, FastAPI)
* Working closely with founders, design, growth, and other engineers to ship high-impact features
* Ensuring scalability, performance, security, reliability and maintainability across the full stack
* Contributing to cloud infrastructure setup and optimisation (AWS, GCP or Azure), containerisation, deployment pipelines, monitoring and optimisation
* Implementing CI/CD pipelines, automated testing, monitoring, and related DevOps practices

* An ability to solve complex problems, work under shifting priorities, and thrive in a fast-paced startup environment
Why this is a compelling opportunity
* You’ll work side-by-side with experienced founders who’ve previously built and exited VC-backed startups
* Competitive salary plus equity, offering genuine upside
* A chance to help shape a generational product and scale it from a small team to large global deployments
