About the role

Key responsibilities & impact

Full-stack features across React, Node/Python, Postgres/Supabase, and AWS (Lambda, ECS, SQS, S3, Dynamo, RDS), N8n, and OpenAI Agents SDK
LLM orchestration pipelines and agentic workflows that distill complexity into intuitive context/action architectures — always keeping the human in the loop
A unified memory layer that blends relational, non-relational, and vector databases seamlessly
AI-accelerated development tooling — spec-to-code pipelines, self-documentation, test scaffolding, and automations that make the team faster
Modular, scalable infrastructure designed for heavy AI workloads and built to last

Requirements

What you’ll need

3–5 years of hands-on software engineering experience, with a meaningful portion building AI-native systems
Deep comfort with LLMs, agentic AI orchestration, prompt engineering, embeddings, vector databases, and applied ML
Strong full-stack foundation: React, Node.js, Python, Postgres/Supabase, AWS (Lambda, ECS, S3, Dynamo, RDS), N8n, OpenAI Agents SDK
A proven track record architecting pipelines, agent frameworks, and data orchestration layers that integrate LLMs, embeddings, and automation — systems that reason, adapt, and scale intelligently
A systems thinker who values elegance, modularity, and velocity — and builds with the craftsmanship and curiosity of someone pushing the boundaries of what software can be
How to stand out: Show us what you've shipped. Links to repos, agentic applications in production, infra diagrams you're proud of, or hard problems you solved with LLMs, agentic workflows, or ML pipelines — any of these go a long way.
