About This Role

This is a hands-on engineering role to design, build, and ship production ML systems that power real customer-facing products. This zero-to-one role offers significant technical ownership within an early-stage Silicon Valley startup building a core AI platform.

Responsibilities

  • Design, build, and deploy production-grade ML systems solving real-world problems
  • Develop models for high-quality parsing and extraction across structured and semi-structured data, including HTML
  • Select the right technical approach per problem, including fine-tuning, RAG, reinforcement learning, hybrid systems, or deterministic solutions
  • Fine-tune and RL-train models as needed, iterating based on live performance
  • Optimise systems for low latency and low cost without sacrificing quality
  • Own the full ML lifecycle: data collection, feature engineering, training, evaluation, deployment, monitoring, and iteration
  • Build scalable ML pipelines and low-latency inference systems suitable for production
  • Collaborate closely with product and platform engineers to integrate ML into customer-facing applications
  • Define best practices around experimentation, model versioning, evaluation, and monitoring

Requirements

  • 10+ years of experience in machine learning, applied AI, or related engineering roles
  • Strong fundamentals in machine learning, statistics, and algorithms
  • Demonstrated experience deploying ML systems into production environments
  • Deep hands-on experience with Python and ML frameworks such as PyTorch, TensorFlow, or scikit-learn
  • Experience with LLMs, embeddings, fine-tuning, RAG pipelines, and reinforcement learning
  • Experience optimising production systems for performance, latency, and cost
  • Familiarity with modern ML infrastructure and data stacks, including cloud platforms, feature stores, vector databases, and orchestration tools
  • Ability to operate effectively in fast-moving, ambiguous startup environments

Qualifications

  • 10+ years of experience in machine learning, applied AI, or related engineering roles

Nice to Have

  • Experience building parsing, extraction, or transformation systems
  • Background in personalization, search, recommender systems, or NLP
  • Early-stage startup experience or building systems from scratch
  • Prior mentorship or technical leadership experience
  • Experience working with privacy-sensitive or regulated data
