## Description

About the company

Our client is a fast-growing software company.

The role

Raydar is recruiting for this role on behalf of our client. Own the machine learning layer of a production software product, covering model integration, data pipelines and the testing frameworks that confirm changes work. This is a hands-on engineering seat as one of the earliest engineers, with real influence over architecture and a focus on frequent releases to live users.

What you'll do

\- Own AI features from design through deployment, including how models are instructed, how they pull in information and how they call other services.

\- Create automated evaluation tooling ahead of new releases so model changes are verified rather than assumed.

\- Bring response time and running costs down to levels that hold up under real production load.

\- Diagnose unclear product problems and determine whether the cause is the model, the data or the user experience, then resolve them.

\- Release to production weekly and monitor how changes behave in real use.

\- Make early architecture decisions that will shape the platform for years.

## Requirements

What we're looking for

\- A computer science degree, ideally from a highly ranked institution.

\- Solid practical Python experience developing AI and ML services.

\- Experience creating LLM evaluation systems that successfully caught regressions.

\- A track record of launching AI-driven software to live users, beyond research prototypes or internal demos.

\- Experience at a company known for a rigorous engineering bar.

\- Experience working at a growth-stage startup.

Bonus points

\- Contributions to the wider developer community, such as published work or personal projects.

\- Background in machine learning or model tuning.

\- Experience in commerce or marketplace environments.

\- Base salary: USD 150,000 to 250,000 per year
