The Role
The role involves developing AI-powered features using React and Python/Django, ensuring ownership of product features while collaborating closely within a small team.
Summary Generated by Built In

About the role: You'll join Celara to help an established business go all-in on agentic AI to transform how their team works. You'll own product features end-to-end on their AI-powered platform, from understanding the why through shipping.

The exciting part is helping a profitable, established company move through the agentic AI revolution from the inside. It’s not a big established AI org - but you'd have the opportunity to be one of the first there doing this kind of work, with outsized input on how it gets shaped.

The work: The stack is mostly React (Ant Design, Jest) on a Python/Django backend, deployed on Azure with Docker and CI/CD. We want someone who is strong with agentic workflows, constantly learning, and has a product mindset.  

You will be expected to lead through to a solution with flexibility and confidence. Some days you're deep in React; some days you're tracing product flows end-to-end; some days you're poking at SQL Server queries or wiring up Azure / OpenAI / Anthropic infra. We care more about how you approach unfamiliar problems than which boxes you've already ticked.

Why this is interesting

    • Shape how AI gets built into a working business, not maintain what's already there

    • Small, flexible team — decisions happen fast, you'll wear multiple hats

    • A strong CTO who's a real mentor — you'll learn a lot working with them

    • High autonomy by default; you'll often be a strong voice in the room on agentic dev practices, and we want you to push us

Requirements

    • 5+ years building production web apps; track record of owning what you ship

    • Strong React + TypeScript fundamentals

    • Comfortable with REST APIs, Jest, and SQL basics

    • Current with agentic AI development — Claude Code, Codex, MCP, building tools

    • Curious generalist — you don't need to be an Azure or SQL Server expert, but you should be able and willing to learn, dig in and figure things out

    • Self-directed; happy in a small team where roles are fluid

    • Strong English, spoken and written

    • Nice to have: Python/Django, Azure, Docker/CI/CD in production.

What we offer:

    Real ownership over features. A small, strong technical team — no bureaucracy. Work on AI tooling that demonstrably changes how a real business operates. Competitive compensation (we'll share a range early in the process).

Skills Required

  • 5+ years building production web apps
  • Strong React + TypeScript fundamentals
