Machine Learning Engineer

Company

We train models that predict how well someone will perform on a job better than a human can. Our platform sources, vets, and onboard expert contractors who help train AI models across a wide range of domains. The technology is used by the top five AI labs. We grew from a $1‑$500M run rate in the last 17 months, averaging 11% week‑over‑week growth in July, 18% in August, and 19% in September, and we maintain profitability while scaling quickly.

Role

As a Machine Learning Engineer, you’ll be a key contributor to the backbone of our core product : models and systems that power talent discovery, evaluation, and trust. You’ll blend generalist backend engineering with applied machine learning, designing and deploying models, building scalable infrastructure, and collaborating with product and operations teams to solve real‑world problems.

Responsibilities

Research, train, and deploy production ML models (fraud / cheating detection, candidate engagement and conversion prediction, search / recommendation).

Build backend infrastructure and APIs to serve ML models at scale.

Collaborate with product engineers, sourcing / operations, and other teams to align models with business impact.

Run experiments, analyze results, and iterate quickly to improve model and product performance.

Wear multiple hats—sometimes data scientist, sometimes backend engineer—always a problem solver.

Qualifications
