Introduction

We’re on the lookout for a Phoenix Elixir Engineer who’s passionate about building robust, scalable web applications. You’ll work closely with designers, frontend developers, and product managers to create high-quality backend services and APIs using Elixir, Phoenix, and Ash Framework. We’re seeking someone with a strong foundation in functional programming principles and experience with Phoenix-based applications.

This role is suitable for a Mid to Senior-Level developer who’s confident in Elixir fundamentals and excited to contribute to our growing product ecosystem. A lead position is available for the right candidate with extensive experience. We’re also happy to welcome Rubyists and Ruby on Rails experts looking to migrate their skillset to Elixir Phoenix, as the transition path is well-established and many concepts carry over effectively.

Through our self-sovereign data infrastructure, we enable individuals and businesses to create Personal Data Accounts that unlock secure, ethical, and interoperable data flows. We’re building the backbone of a new digital economy — one that’s private, human-first, and future-ready.
