Job Description

Senior AI Full Stack Developer — Arithmiks

You will take an AI feature from a feasibility question on a client's data through to a shipped product — the model, the API around it, and the interface a real user touches.

Validate whether a client's data supports the product they want, and build the pipeline or model that proves it.

Build the full-stack product around that model — React on the front, Node or Python on the back, deployed on real cloud infrastructure.

Write the evaluation, monitoring, and runbooks the client's own team will operate after handover.

Work directly with clients from the first call, without an account layer between you and the decision.

Requirements

4+ years building production software, with real experience taking an ML or LLM feature from prototype to production.

Strong React and Node or Python, and comfort owning a feature across the full stack, not just one layer of it.

Hands-on experience with at least one major cloud provider.

Judgement about where intelligence genuinely helps a product and where it's just noise.

Client-facing experience in a consulting or studio setting.
