Question 1

How quickly can I hire a Machine Learning contractor on consultant.dev?

Accepted Answer

Senior ML contractor roles typically fill within 2 weeks. The ML contractor market is smaller and more specialised than general software engineering, top profiles are placed quickly. Specifying the ML stack (PyTorch, TensorFlow, scikit-learn), the use case (CV, NLP, LLMs, tabular), and whether you need research-oriented or production-focused work will attract the right specialist.

Question 2

What should I look for when hiring a Machine Learning contractor?

Accepted Answer

Assess domain fit first, LLM engineering, computer vision, and classical ML require different depth. Production ML contractors should demonstrate MLOps experience: model serving, monitoring, retraining pipelines, and infrastructure (SageMaker, Vertex AI, MLflow). Research-oriented ML contractors bring different value. For applied ML roles, Python proficiency and cloud platform familiarity (AWS, GCP, Azure) are near-essential. Review prior production deployments, not just notebook-based experimentation.

Question 3

What are typical Machine Learning contractor engagement lengths?

Accepted Answer

ML contractor engagements vary widely by project type. Proof-of-concept and feasibility projects run 4-12 weeks. Production ML pipeline builds run 3-9 months. MLOps platform engineering roles often extend to 12+ months as ongoing platform ownership. LLM integration projects in 2026 are typically 3-6 months. Define success metrics and handover expectations upfront, ML projects have a higher ambiguity risk than conventional software delivery.
