• Real-time interactive features built with Phoenix LiveView
  
• Vector DB-backed features such as semantic search embeddings storage and retrieval-augmented workflows
  
• Background jobs and async processing (Oban or similar)
  
• Database design query optimization and migrations in PostgreSQL
  
• Integration with third-party services and internal microservices
  
• Local development standardized via Docker and dev containers

Tech Stack

• Languages: Elixir
  
• Frameworks: Phoenix Phoenix LiveView Ash Framework (AshPostgres AshGraphql/AshJsonApi Ash Authentication as applicable)
  
• Databases: PostgreSQL Vector DB (pgvector Pinecone Weaviate or similar)
  
• AI/LLM: Claude Gemini (API-level integration) Claude Code Cursor GitHub Copilot or similar
  
• Analytics: PostHog
  
• Infrastructure: Docker Dev Containers CI/CD pipelines
  
• Other: Oban/background jobs GraphQL/REST APIs Git
  

• Have hands-on experience with Elixir and specifically the Ash Framework (not just Phoenix alone)
  
• Understand Ashs resource/action/policy model well enough to extend it not just follow existing patterns
  
• Have built real-time or interactive features with Phoenix LiveView
  
• Have worked with vector databases and understand embeddings similarity search and retrieval patterns
  
• Have integrated LLM APIs (Claude Gemini or similar) into production features not just used them as coding tools
  
• Are comfortable using product analytics tools like PostHog to inform engineering decisions
  
• Are comfortable working in Docker-based dev container environments
  
• Have experience deploying and operating applications on (or similar platforms)
  
• Actively use AI coding assistants and understand their strengths and limits
  
• Care about writing code that other people can read and maintain
  

• Genuinely enjoy understanding the business context behind features not just executing specifications
  
• Are comfortable asking "why" and challenging assumptions to ensure decisions align with business goals
  
• Have experience collaborating with product business and non-technical stakeholders
  
• Can translate between technical and business language effectively
  
• Enjoy working on systems that serve real users at real scale and care about user impact
  
• Demonstrate ownership mindset: you think about long-term implications not just shipping code
  
• Learn fast and dont need to be told twice
  
• Are curious about how your work affects the broader business and product strategy
  

• Real Ash Framework experience > general Elixir/Phoenix experience alone
  
• Business acumen and product thinking > years of experience
  
• Communication and collaboration skills > individual technical prowess
  
• AI-fluency (both as a coding tool and as a feature you build) > years of experience
  
• Clear thinking and strategic mindset > buzzwords
  
• Ownership mindset and business impact focus > following instructions
  
• Side projects experiments GitHub repos or well-documented failures are a big plus
  

• Experience with AshAdmin AshStateMachine or AshPaperTrail
  
• Experience building RAG (retrieval-augmented generation) pipelines
  
• Exposure to observability tooling (Grafana Prometheus or similar)
  
• Experience in product-driven or cross-functional engineering environments
  
• Familiarity with Specification-Driven Development (SDD) or similar methodologies
