Product ML Engineer

Stack

Responsibilities

• ▹Embed directly within a product team (SMB, Scaler or Enterprise) on focused ML problems tied to clear customer and business outcomes
• ▹Own ML projects end to end: frame the problem, choose the approach, execute the plan, ship the feature and monitor its performance in production
• ▹Make the build vs. buy decision: when to fine-tune or build a model yourself versus integrating an external model, API or existing library
• ▹Move from idea to production quickly, on projects scoped in weeks, prioritising rapid iteration and customer impact
• ▹Work closely with the ML team, leveraging shared infrastructure, evaluation tooling and expertise
• ▹Stay close to users: get rapid feedback, monitor how people use what you've shipped and drive the next iteration
• ▹Balance technical depth with pragmatism: know when deeper modelling is necessary and when an existing solution is good enough
• ▹Write production code in the product team's codebase rather than working primarily in research notebooks
• ▹Own quality in production: build sound evaluations, monitor performance and investigate failures once the feature is live

Requirements

• ▹2+ years of hands-on experience building and shipping ML-powered products, with strong experience in PyTorch or equivalent frameworks such as TensorFlow or JAX
• ▹Applied-science depth: fine-tuning vision or diffusion models, designing meaningful evaluations and debugging training runs
• ▹Pragmatic builder who happily uses an external model, API or existing library when that is the fastest route to value
• ▹Product-minded: success measured through shipped features, user behaviour and business outcomes
• ▹Comfortable moving between experimentation and production engineering, writing maintainable code in a real product
• ▹Strong ownership: able to take an ambiguous ML problem and drive it through to production
• ▹Enjoys short feedback loops and iterating quickly

Nice to have

• ▹Experience shipping generative image models or diffusion models into production
• ▹Experience evaluating third-party AI APIs against internal alternatives
• ▹Experience working in a fast-growing startup or directly within a product team
