  • Must have hands-on experience with tree-based models (XGBoost or LightGBM) and regression, model evaluation, and explainability (SHAP).
  • Should have practical LLM experience: prompting, tool calling, retrieval-augmented generation, embeddings and vector search.
  • Should have experience with ML pipelines and model deployment on a major cloud, and with Git, testing and code review.
  • Should have strong statistics and metrics knowledge, including error metrics.
  • Must have google cloud experience (Vertex AI, BigQuery, Gemini, Vector Search), or an equivalent cloud (AWS/Azure).

  • Design the GenAI agent: tool calling, retrieval-grounded generation, session memory, guardrails, human approval for actions and layered prompt-injection protection.
  • Define evaluation: golden test sets, groundedness, tool-routing accuracy and release gates, and run regular quality reviews.
  • Define serving and MLOps practice with the architect and DevOps: model registry, pipelines, drift monitoring, retraining and rollback.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
