Research Engineer, Machine Learning (UK VISA SPONSORSHIP)

Employer: Anthropic

Position: Research Engineer, Machine Learning (RL Velocity)

Salary: £370,000 – £630,000 

Job Type: Full Time.

Work location: London

FULL JOB DESCRIPTION

Anthropic’s mission is to create reliable, interpretable, and steerable AI systems. We want AI to be safe and beneficial for our users and for society as a whole. Our team is a quickly growing group of committed researchers, engineers, policy experts, and business leaders working together to build beneficial AI systems.

The RL Velocity team owns the efficiency and reliability of our RL Science stack – the infrastructure, tooling, and systems that let researchers iterate quickly on training runs. As a Research Engineer on the team, you’ll build and improve the core platform that underpins how we do RL at Anthropic, removing bottlenecks that slow down research and making it easier for the broader org to ship better models faster. This is high-leverage work: small improvements to velocity compound across every researcher and every run.

Your Responsibilities include:

• Build and improve the RL training infrastructure that researchers depend on day-to-day

• Identify and remove bottlenecks across the RL stack: debugging, profiling, and rearchitecting where needed

• Partner closely with researchers and with adjacent engineering teams (inference, sandboxing, and many more) to understand pain points and ship tooling that makes them faster

• Own the reliability and performance of research runs end-to-end

• Contribute to design decisions that shape how Anthropic does RL at scale

Work schedule 

Full time role 

You will have

• Have strong software engineering fundamentals and a track record of building performant, reliable systems

• Have worked on ML infrastructure, distributed systems, or research tooling

• Care about enabling other people’s work and find leverage through platforms rather than individual experiments

• Are comfortable operating across the stack, from low-level performance work to RL algorithms

• Have a bias toward shipping and iterating quickly, with a mix of high agency and low ego

• Strong candidates may also have

• Experience with large-scale distributed training (RL, pre-training, or post-training)

• Familiarity with JAX, PyTorch, or similar ML frameworks

• A track record of operating at the edge of research and infra in a fast-moving environment

Requirement 

• Minimum education: Bachelor’s degree or an equivalent combination of education, training, and/or experience

• Required field of study: A field relevant to the role as demonstrated through coursework, training, or professional experience

• Minimum years of experience: Years of experience required will correlate with the internal job level requirements for the position

• Location-based hybrid policy: Currently, we expect all staff to be in one of our offices at least 25% of the time. However, some roles may require more time in our offices.

Benefit 

Visa sponsorship: We do sponsor visas! However, we aren’t able to successfully sponsor visas for every role and every candidate. But if we make you an offer, we will make every reasonable effort to get you a visa, and we retain an immigration lawyer to help with this.
