What You Will Be Doing

  • Turn detection problems into well-posed ML problems with a clear hypothesis, baseline, and success criteria
  • Build, label, and version the datasets used for training and evaluation
  • Design, train, and tune models; analyze their errors and feed the findings back into data, features, or architecture
  • Define evaluation protocols: metrics, splits, held-out test sets, and thresholds tied to product constraints such as false-positive rate and latency
  • Take models from experiment to production on AWS together with MLOps and software engineers, including packaging and inference optimization
  • Monitor deployed models for drift and drive retraining when needed
  • Keep experiments reproducible and documented, and present results and trade-offs to engineering and product

What We Need From You

  • 3+ years of hands-on experience as a Machine Learning Engineer, Data Scientist, or Applied Scientist, with models delivered to production
  • Bachelor’s or Master’s degree in Computer Science, Mathematics, Statistics, or a related field
  • Strong Python and the scientific stack (NumPy, pandas, scikit-learn, PyTorch or TensorFlow)
  • Solid grounding in statistics and ML fundamentals: bias/variance, class imbalance, leakage, calibration
  • Practical experience with AWS for data storage and training workloads
  • Clear written and spoken English

Nice to Have

  • Experience with experiment tracking and model registries (MLflow, Weights & Biases, or similar)
  • Experience optimizing and packaging models for inference (quantization, distillation, ONNX, Docker)
  • Knowledge of file formats and binary analysis
  • Background in cybersecurity, threat detection, or another adversarial domain
  • Publications, open-source contributions, or a competitive ML track record

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.
