Senior ML Engineer (NLP) – Build Core AI Platform in London

We are looking for a Senior Machine Learning Engineer (Natural Language Processing) to join our team. You will be an early shaper of the design and architecture of the ML/AI technology at the core of our platform, and work closely with the founding team to deliver 10x value to our clients. As an early-stage startup, we pride ourselves on our ability to roll up our sleeves and build from scratch. You'll ship code frequently, iterate quickly based on feedback, and still meet the stringent security, performance, and uptime requirements our clients expect.

We all love to build, scale, and grow: our leadership team has a strong track record of building products, scaling teams, and driving growth, and our ambitious engineers join us from leading tech companies and unicorns. If you're passionate about turning complex problems into simple, elegant solutions, this role is for you. You'll have a meaningful opportunity to shape our engineering culture from the ground up.

What you'll do:

• Develop ML/AI functionality at the core of our platform, owning end-to-end design and implementation.
• Solve abstract, open-ended problems using modern AI tools and models across the entire data and engineering stack, working closely with a highly capable team.
• Train, evaluate, and deploy models for intelligent document processing, web data parsing, classification, search, and matching.
• Design and run experiments to explore new approaches, models, and data usage that improve our agents/LLMs, balancing innovation and pragmatism and clear trade-offs.
• Ensure our AI products evolve quickly and safely by applying strong development and testing practices.
• Continuously improve our data science and AI practices, helping define standards, processes, and tooling that align with industry best practices.

What you bring:

• You are an effective and self-driven builder.
• 3+ years of experience as a machine learning/AI engineer in product-centric settings.
• Experience in production-level Python.
• Experience implementing AI projects (prompt engineering, fine-tuning, multi-agent frameworks, LLMs, conversational AI).
• Strong understanding of modern AI tools and approaches.
• Bachelor's or Master's degree in Computer Science or a related field.
• Excellent communication skills and ability to work collaboratively in a fast-moving environment.

Our Offer:

• Tackle meaningful problems with real-world impact.
• Competitive salary and equity package.
• Join us onsite in our offices in London or Porto.
• Flat hierarchy with direct access to founding team.
• Top-of-the-line equipment.
• Private health insurance, plus sick and compassionate leave as needed.
