Job Description
We're looking for a Founding Backend Engineer with entrepreneurial DNA to build the API infrastructure that powers AI agent orchestration. You're a technical generalist who ships production code daily while shaping both our technology and engineering culture. You’re a life-long learner and lead with curiosity.
We believe in an AI-first mindset – not just in the products we build for customers, but in how we work. Use AI to 10x your productivity, automate tedious tasks, and ship faster than traditionally possible.
Our philosophy: Build pencils, not pens. Ship in weeks, not months. Let customer feedback and AI acceleration guide our iteration.
Tech Stack: Python, FastAPI, GraphQL, PostgreSQL, DynamoDB, AWS/ECS, Terraform, Databricks, WebSockets, Message Queues (SQS/Redis), Event-driven architectures
Why This Role?Customer Impact – Build infrastructure that delivers AI magic to enterprise users
AI-Powered Development – Use AI tools (Claude Code, Cursor, Copilot, etc.) to ship 10x faster
Product Ownership – Shape product decisions, not just implement specs
Technical Variety – APIs in the morning, agent orchestration after lunch, infrastructure by evening
Entrepreneurial Environment – Your ideas matter, your impact is immediate
Design and build APIs (FastAPI/GraphQL) for AI agent data access
Implement event orchestration for multi-agent workflows (message queues, pub/sub, task management)
Create MCP servers and async communication systems (SQS, Redis, event streams)
Design database schemas optimized for customer access patterns
Build real-time capabilities via WebSockets
Think customer-first when designing developer experiences
Use AI tools to accelerate development and automate repetitive tasks
Partner with AI Architect and Data Engineer on system design
Own infrastructure/DevOps when needed (startup life)
70%+ hands-on coding while making architectural decisions
Generalist expertise – databases, APIs, infrastructure, queuing systems, and more
Product mindset – build for customer delight, not technical elegance
Startup experience – thrive in ambiguity, ship fast, make decisions with incomplete data
AI-first approach – use AI to transform both what we build AND how we build it
Python proficiency – ready to hit the ground running
Event-driven systems – message queues, async patterns, distributed architectures
Enterprise scale – built real production systems, not just prototypes
Founded something or been employee #1-10
Specific experience: Kafka, RabbitMQ, Celery, Temporal, vector DBs
Built developer-loved APIs or AI-powered products
Full-stack capabilities or polyglot programming
Owner mentality – think like a founder
AI acceleration – constantly ask "how can AI make this faster/better?"
Customer obsessed – every technical decision serves the user
Pragmatic builder – know when good enough beats perfect
Self-directed – figure things out without hand-holding
