London, Greater London, United Kingdom Fractal Full time
Job Title: Machine Learning Engineer

The Opportunity

This is a high-reward position for an individual passionate about leading the forefront of the Intelligence Age, enabling human organisations to work with increasingly complex systems of agents.


About Fractal

We're creating the first 'Human x Agentic Orchestration Layer'. This layer sits across both human and agent intelligence, passing work from human to machine (model, agent, tool), and back again.


About the Role

You'll be at the forefront of defining how AI orchestration works at scale as part of our Founding Team.


Your Responsibilities:
  • Pioneer AI agent development and implementation within our orchestration platform
  • Design sophisticated systems for intelligent task planning, delegation, and coordination between AI agents and human workers
  • Architect scalable production-ready systems in cloud environments (AWS) with focus on performance, reliability, and cost optimisation
  • Develop complex workflows for task routing and execution across multiple AI models and human operators
  • Create robust monitoring and evaluation systems to track agent performance and workflow efficiency
  • Integrate various AI models and tools into our orchestration layer, ensuring seamless interoperability
  • Work with relational, non-relational, and graph databases to manage and process data efficiently
  • Drive technical initiatives independently from problem identification through solution implementation
  • Contribute to the development of our core orchestration engine and its underlying architecture

Required Experience

Your experience should match well with the following. We value drive, work rate, and tenacity above all else.


What We Offer

We offer 6-figure salary (£120k - £180k), flexible to your experience + Equity. You should want to be an owner more than you want to be an employee.

We treat and compensate like owners from day one, offering equity packages that reflect your contributions.
