What do Machine learning engineers in London work on?

The roles on this page divide roughly into two clusters. One cluster is product-facing ML engineering: building, training, and evaluating models that ship inside real products. Wayve's postings, for instance, include simulation-focused roles and a performance tooling position centred on profiling and optimising model training and inference across cloud and embedded hardware. The other cluster sits closer to infrastructure and operations: designing and maintaining the pipelines, GPU clusters, and deployment systems that let models reach production. Anaplan's three postings cover this ground explicitly, from an MLOps engineer managing Kubernetes and CI/CD pipelines to a platform lead responsible for FinOps frameworks and generative AI deployment. A smaller strand covers domain-specific work: Mind Foundry's national security roles require onsite client engagement and comfort operating in ambiguous environments. Across all postings, the day-to-day work involves writing production code, making architectural decisions, and collaborating with cross-functional teams rather than pure research.

Skills and experience employers ask for

Python and model evaluation appear in the majority of these postings, and PyTorch, LLMs, and distributed training each appear in roughly half or fewer. GPU work, CI/CD, Docker, and Kubernetes cluster together, reflecting the infrastructure strand. PhD is mentioned in a minority of postings. All counts are mentions in descriptions across this sample of postings, not stated requirements, so the same posting may mention a skill without making it mandatory.

Machine Learning Engineer roles that state a salary

The employers' own advertised ranges, for individual roles at different levels — not an average and not a market rate.

London office, hybrid or remote?

Most postings on this page are listed as onsite, a smaller share are hybrid, and a minority are fully remote. No posting has an unknown work mode. Onsite roles include the Mind Foundry national security positions, which explicitly name London and client-facing work as reasons for the arrangement. The Anaplan MLOps postings do not state a work mode in the sample summaries, so candidates should confirm arrangements directly. Where hybrid or remote is listed, the specific days in-office or geographic constraints are not stated in the fact pack.

Make your application specific to the work

  1. Check the work arrangement first Most roles on this page are listed as onsite; confirm the exact expectation before applying, as some employers do not specify split days or location flexibility.
  2. Review the seniority signals Many postings do not state a seniority level explicitly, so read the summary for signals like team leadership, architectural ownership, or mentoring responsibilities to gauge where a role sits.
  3. Match your infrastructure or product track Postings here divide between ML product work and MLOps infrastructure; tailor your application to show relevant depth in whichever track the role describes, as the skills overlap but the emphasis differs.
  4. Note security clearance requirements Mind Foundry's national security postings may carry clearance requirements that are not fully stated in the summaries; contact the employer early if eligibility is uncertain.

Questions about Machine Learning Engineer jobs in London

Only one posting on this page advertises pay: Cohere's Senior ML Systems Engineer, Frameworks and Tooling, which lists a range of £295,000–535,000. The remaining postings do not state a salary, so that single figure cannot be treated as representative of the group.

Visa sponsorship is not mentioned in the fact pack for any of these postings. You would need to check each employer's application page directly.

A PhD is mentioned in a minority of postings in these listings, but it is a description mention rather than a stated requirement in every case. The Mind Foundry summaries specify a STEM degree or equivalent, not specifically a doctorate.

One posting is listed as intern level. A large share of postings do not state a seniority level, and the remainder skew toward senior, staff, and lead grades, so genuinely entry-level openings are scarce in this snapshot.

Wayve, Waymo, Anaplan, Mind Foundry, Scale AI, Cohere, Graphcore, and Nebius each have more than one posting in these listings. All other employers represented here have a single posting.
