Machine Learning Engineer, Performance Tooling

Wayve; London (KY); Hybrid; USD 120,000 - 180,000; Full time

Job summary

Wayve is seeking a Software Engineer, AI Performance Tooling to join the AI Performance Tooling team, accelerating model training and inference across cloud and embedded hardware. You will design self-service performance tools, predict latency and compute costs, and work with model, compiler, runtime, platform, and hardware teams to turn measurements into actionable recommendations.

This full-time, hybrid in-office role embeds you in a fast-moving environment where ownership and cross-team

Qualifications

• Hands-on performance engineering in complex systems.
• Own a tool or service end to end — design, delivery, and adoption by other teams.
• Strong Python skills, and comfort profiling and instrumenting large production codebases.
• Hands-on experience developing deep learning models with PyTorch.
• Data analysis skills to turn noisy measurements into conclusions you can defend.
• Judgment to turn an ambiguous performance question into a measurable one, and to prioritize what matters.
• Quantitative communication clear enough to influence another team’s priorities.

Responsibilities

• Design and build reliable, self-service performance tools that scale across models, hardware targets, and development workflows.
• Shape how Wayve measures and predicts AI performance, and set the standards other teams build on.
• Model theoretical peak for a platform, compare with achieved performance, and pinpoint where efficiency is lost at layer and op level.
• Predict latency, memory, utilization, and compute cost of a model or recipe change before spending compute.
• Own monitoring and regression alerting across model builds and training runs.
• Work with training and runtime engineers to set performance targets and make the case with data.

Job description

Before the detail, here's the challenge you'd help us solve.

We build the embodied intelligence that moves real vehicles safely, and the ecosystem a billion machines will run on in the future. Very few people in AI can say this. Every role here, whatever the team, plugs into that.

Here’s what this particular role covers.

The role

You’ll join the AI Performance Tooling team within Wayve’s AI Performance organization, which makes model training and inference faster, more efficient, and more predictable across cloud and embedded hardware. Our mission is to enable data-driven AI performance decisions across priority workloads and hardware targets: Measure performance teams can trust; Monitor trends and catch regressions; Predict the cost of changes before we run them; Advise on bottlenecks and prioritized opportunities.

You’ll build tools that reason across the AI stack — models and operators, compilers, runtimes, accelerators, and distributed training infrastructure — turning profiling data into a clear picture of where time, memory, power, and compute go, and what proposed changes will do to latency, throughput, compute spend, and capacity.

You’ll work closely with model, compiler, runtime, platform, and hardware teams, bringing a cross-stack view that turns measurement into clear recommendations.

Key responsibilities

• Design and build reliable, self-service performance tools that scale across models, hardware targets, and development workflows.

• Shape how Wayve measures and predicts AI performance, and set the standards other teams build on.

• Model theoretical peak for a platform, compare with achieved performance, and pinpoint where efficiency is lost at layer and op level.

• Predict latency, memory, utilization, and compute cost of a model or recipe change before spending compute.

• Own monitoring and regression alerting across model builds and training runs.

• Work with training and runtime engineers to set performance targets and make the case with data.

About you

In order to set you up for success as a Software Engineer, AI Performance Tooling at Wayve, we’re looking for the following skills and experience.

Essential

• Deep, hands-on performance engineering in complex systems: profiling, roofline analysis, latency and throughput optimization, and root-causing what limits a workload.

• A track record of owning a tool or service end to end — design, delivery, and adoption by other teams.

• Strong Python skills, and comfort profiling and instrumenting large production codebases.

• Hands-on experience developing deep learning models with PyTorch.

• Data analysis skills to turn noisy measurements into conclusions you can defend.

• Judgment to turn an ambiguous performance question into a measurable one, and to prioritize what matters.

• Quantitative communication clear enough to influence another team’s priorities.

This is a full-time role based in-office. At Wayve we want the best of all worlds so we operate a hybrid working policy that combines time together in our offices and workshops to fuel innovation, culture, relationships and learning, and time spent working from home.

A quick, honest note before you apply.

Wayve is not a mature, fully-structured place with the playbook already written. Much of how we work is still being written, and if you join, you’ll help write it. That suits people who want real ownership more than people who need a settled structure from day one.

If that sounds like the kind of problem you want to spend your time on, we’d really like to hear from you.
