We are looking for an Elixir Developer to join our team building backend services for scalable, production-grade applications. This is not a role where you simply execute PRDs. Instead, you will be a business-minded engineer who deeply understands the product use cases, business objectives, and strategic implications of technical decisions.
You will design and extend backend services using the Ash Framework, working across resources, actions, and data layers to ship features rapid without sacrificing correctness. Our backend is Elixir/Phoenix with Ash as the core application framework, backed by PostgreSQL, deployed on Fly.io. You will spend most of your time inside Ashs resource-oriented patterns rather than hand-rolling boilerplate.
This is a framework-deep role with a business-first mindset.
Key Responsibilities
- Business Product Collaboration: Work closely with product managers and business stakeholders to understand use cases, market context, and business objectives before diving into technical implementation
- Ask critical questions about business impact, trade-offs,
and long-term implications of technical decisions
- Communicate technical constraints, risks, and opportunities in business-friendly language to non-technical stakeholders
- Contribute to architectural and strategic decisions by providing context on how technical choices affect business outcomes
- Technical Design Development: Design and build Ash resources, actions, calculations, and policies for core product features with a deep understanding of their business purpose
- Write clean, testable Elixir code following OTP and Phoenix conventions
- Build interactive, real-time UI where needed using Phoenix LiveView
- Design and maintain PostgreSQL schemas, migrations, and query performance with business scalability in mind
- Build and extend APIs (GraphQL/REST via AshGraphql/AshJsonApi or Phoenix controllers) that serve real production traffic
- AI Advanced Features: Integrate LLM APIs (Claude, Gemi
