We’re Unitary — an AI startup building systems that combine human expertise with intelligent agents to automate complex customer operations. Our technology powers trust & safety and content moderation at scale, analysing millions of daily images and videos to make the online world safer.


We’ve raised $25M+ from Creandum and Plural, and are growing fast — expanding our product, team, and global impact.


The Role

We’re looking for a Machine Learning Engineer to help design, build, and deliver AI-powered automation for our customers. You’ll collaborate directly with users to understand their workflows, prototype intelligent “Virtual Agents,” and scale these into production systems.

You’ll work across the full stack — from ML pipelines to deployment — ensuring our solutions are fast, reliable, and impactful.

  • Design and implement AI systems that automate customer workflows
  • Contribute to the Virtual Agent development platform
  • Integrate and optimise ML models in production
  • Drive reliability, observability, and performance across AI services
  • Collaborate with customers and internal teams to deliver scalable solutions


About You

  • Strong skills in Python and applied Machine Learning
  • Passion for solving real-world problems with AI
  • Interest in agentic AI systems, MLOps, and Kubernetes
  • Excellent communicator who thrives in a collaborative, remote-first team
  • Excited to shape a growing startup and have a visible impact


Nice-to-haves: experience with CI/CD, Terraform, LLMs, or startup environments.


Why Unitary

  • Remote-first within 3 hours of UK time
  • Competitive salary + equity
  • Flexible hours and generous parental/sick leave
  • Annual budgets for learning and wellness
  • 3 annual team off-sites across Europe


Join us to build AI systems that make the internet safer — and smarter.
