About ve2ventures

We’re ve2ventures, a venture studio that invests in external startups and also builds our own companies from the ground up. We’re a mix of entrepreneurs, product people and tech experts who love building innovative products. Together, we’re building the world’s largest sports and media tech ecosystem.

In 2 years, we’ve grown to a team of 60+, working on over 20 ventures and supported by 35 investors. As our startups grow, so does our need for strong technical talent. That’s where you, our new Machine Learning Engineer, come in. You’ll join the data science team behind PadelPlay, our padel performance platform. It turns data from a wearable sensor into shot detection, technique feedback and AI coaching for thousands of players.

The Role

As a Machine Learning Engineer, you’ll own models from the first look at the data through to production. You’ll build, evaluate and ship the ML and AI features players use after every session. You’ll work closely with the app, backend and product teams, and as you grow you’ll take on more of the technical decisions about how we model, deploy and monitor what we build.

What You’ll Do

• Own the full ML lifecycle: data collection and labelling, feature engineering, training, rigorous evaluation, deployment and monitoring.
• Design evaluation that holds up in the real world. That means testing on users the model hasn’t seen, and being honest about what the numbers can and can’t tell us.
• Build and maintain the data pipelines and serving infrastructure behind our models (serverless functions, queues, object storage, SQL/NoSQL databases) across dev, staging and production.
• Build LLM-powered features such as our AI coach: prompt design, tool calling, retrieval, multi-language output and guardrails, using APIs from OpenAI, Anthropic and TypesafeAI.
• Use AI-assisted, agentic development in your own workflow (e.g. Claude Code) to move fast without cutting corners.
• Turn product questions from the PM and coaches into clear experiments, and explain the results to non-technical stakeholders.
• Help improve our tooling, reproducibility and code quality as the team grows.

What You Bring — Required

• 3–5 years of experience as an ML Engineer, Data Scientist or similar, with models you’ve taken to production.
• Strong Python and the standard ML stack (pandas, NumPy, scikit-learn; PyTorch or similar).
• Solid grounding in classical ML and evaluation: cross-validation, avoiding leakage, handling class imbalance, choosing the right metric.
• Experience deploying and maintaining models or data services on a cloud platform (Azure preferred).
• Hands-on experience with LLM APIs (OpenAI, Anthropic or similar).
• Comfort with SQL and working with messy, real-world data.
