• Build and extend APIs (GraphQL/REST via AshGraphql/AshJsonApi or Phoenix controllers) that serve real production traffic
  

• Integrate LLM APIs (Claude, Gemini) and vector databases into product features (semantic search, embeddings, retrieval -based workflows)
  
• Use AI coding assistants effectively to accelerate development without sacrificing code quality
  
• Understand the business implications of AI -powered features and their impact on user experience and product strategy
  

• Instrument features with product analytics (PostHog) to track usage and inform iteration

• Workflow logic, versioning, and multi -step business processes modeled declaratively in Ash
  
• 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
  
• Deployment, release management, and scaling on Fly.io
  
• Production debugging, monitoring, and performance tuning
  

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: Fly.io, 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 Ash's 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 Fly.io (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 don't 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
