Back End Developer

Who You Are

You're a seasoned Backend Engineer with 5+ years of experience who thrives on building

products from zero to one. You're a technical leader who can own an entire product's backend

architecture, make architectural decisions, and mentor junior engineers. While

backend-focused, you understand frontend concepts well enough to review code and ensure

smooth integration. You understand that in an early-stage startup, you need to balance technical

excellence with pragmatic choices that get products to market quickly. You're excited about

taking full ownership of backend systems while building and guiding a small engineering team.

Responsibilities

- Take complete ownership of backend architecture for one core product vertical - from

design to delivery to ongoing optimization

- Lead and mentor 2-3 junior engineers while maintaining hands-on involvement in critical

features

- Design and build robust APIs using Python (FastAPI/Django/Flask) that power our web

and mobile applications

- Build and optimize cloud infrastructure on AWS and Azure, implementing

containerization with Docker and orchestration with Kubernetes

- Set up monitoring and observability using Grafana and related tools, ensuring system

health at scale

- Integrate with third-party AI services including LLM APIs (OpenAI, Anthropic, etc.) and

voice technologies (STT/TTS)

- Establish engineering best practices including CI/CD pipelines, code reviews, and testing

strategies

- Partner directly with founders and product teams to translate business requirements into

scalable backend solutions
