We work in a remote-only model, in a team of experienced engineers where autonomy, technical reliability, and responsible decision-making matter.
Your responsibilities
- Working with data: preparation, analysis, feature engineering, validation.
- Projects involving vision computing, predictive maintenance, and time series.
- Implementing models as APIs and integrating them with client systems.
- 10–20% research — as needed, but the job is primarily delivery.
- Opportunity to expand into LLM/RAG, if desired.
Our requirements
- At least one commercially deployed ML project.
- Strong knowledge of:
- at least one DL framework (PyTorch or TensorFlow).
- Ability to run the full ML lifecycle:
- SQL knowledge sufficient for analytics and basic transformations.
- Basic familiarity with cloud (AWS/GCP/Azure).
