Technical Lead, Machine Learning

Our client is an AI-native product company built to replace how billions of people manage their digital lives — starting with email, notes, and task tools that were never designed to be AI-native. It's backed by multi-million-dollar investment and built remote-first from day one, with a clear target: cut the time it takes users to get everyday things done by roughly 90%. That means solving the problems most AI products avoid — long-running workflows, persistent context, and reliable behavior under real-world, non-deterministic conditions. The team is small and high-talent-density by design, not by necessity, and moves at a pace that matches the scale of what it's building.

As Technical Lead, Machine Learning, you own the execution layer of the company's intelligence — translating research direction into reliable, scalable, production-grade ML systems. This role sits at the intersection of research, infrastructure, and product: you're responsible for making models trainable, deployable, observable, and performant under real-world constraints.

• Own end-to-end ML system execution: data pipelines, training workflows, evaluation systems, inference architecture, deployment

• Fine-tune and adapt models using state-of-the-art methods — LoRA, QLoRA, SFT, DPO, distillation

• Architect and operate scalable inference systems, balancing latency, cost, and reliability

• Design and maintain data systems for high-quality synthetic and real-world training data

• Implement evaluation pipelines covering performance, robustness, safety, and bias, in partnership with research leadership

• Own production deployment, including GPU optimization, memory efficiency, latency reduction, and scaling policies

• Collaborate closely with application engineering to integrate ML systems cleanly into backend, mobile, and desktop products

• Make pragmatic trade-offs and ship improvements quickly, learning from real usage

• Work under real production constraints: latency, cost, reliability, and safety

• You've built or shipped real ML systems used by people, not just demos

• You're comfortable working with large models and understanding their failure modes

• You write strong, production-grade code and care about system correctness

• You're self-directed, pragmatic, and take full ownership of outcomes

• You communicate clearly and collaborate well in small, high-trust teams

Python · PyTorch / JAX · GPU-based training and inference systems

• Research and models reliably translate into production-ready solutions with clear performance and quality targets

• ML pipelines, training loops, and inference systems are stable, efficient, and maintainable

• Production issues are detected, debugged, and resolved quickly, minimizing user impact

• Team members are supported, aligned, and able to deliver high-impact ML work with minimal friction

• Iterations on models and systems are measurable, safe, and improve user experience over time

The best products in the world are built by small, world-class teams. Decisions are made collectively, at rapid speed — balancing high-quality shipping with fast learning. You'll be expected to bring structure, exercise judgment, and execute independently.

Compensation and benefits are competitive and vary by location; the package includes base salary and equity, discussed openly with you as part of the process.

If there's a fit, expect 3–4 interviews total, followed by a prompt, transparent decision.
