About the job
Our Mission
Dex exists to help people find work that matches their strengths and interests. Too many talented individuals feel disconnected from their jobs, leaving potential untapped. Dex aims to close this gap by using technology to connect people with opportunities where they can thrive. By supporting more people in doing what they love, we hope to build a happier and more productive world.
We are beginning this journey by connecting ambitious software engineers with companies that value their skills.
About Dex
Dex is backed by investors such as a16z Speedrun, Concept Ventures, and angels from OpenAI, Wise, ElevenLabs, and Meta's board. Our team of 12 works out of the Borough of London. We value ambition, directness, and kindness, and look for people who are authentic and proactive. While we support flexible schedules, we typically meet in person around three times each week.
Role Overview: Founding Machine Learning Engineer
- This position centers on machine learning engineering, not research or prompt engineering. A solid grasp of how embeddings represent meaning and how attention affects retrieval is important.
- Large language models (LLMs) are part of the toolkit, but the focus is on understanding and solving problems at the model level, not just using APIs.
- The main goal: build a system that can quickly and accurately stack-rank candidates for new roles in seconds.
- Ownership of the representations and scoring models that power Dex’s ability to match engineers with companies.
- The matchmaking engine developed will underpin future features, including candidate-focused products, automated outreach, and improved sourcing tools.
- Strong engineering skills are as important as machine learning expertise.
What You'll Do
- Lead machine learning projects, delivering efficient and reliable systems.
Location
This role is based in London, with in-person collaboration expected several times a week.
