Software Engineer, On-Device AI

About this role

About NothingNothing exists to make tech feel exciting again. We’re building a different kind of technology company, one that puts design, emotion, and human creativity at the heart of everything we do. From the way our products look and feel to how we communicate and show up in culture, we believe technology should make you feel something. Founded in London in 2020, we’ve grown from idea to global challenger in just a few years. Backed by GV (Google Ventures), EQT Ventures, and C Ventures, and investors like Tony Fadell (iPod), Casey Neistat, and Kevin Lin (Twitch), we’re now sold in 40+ markets with millions of users worldwide.

About the teamAI should run on the devices you carry, work across all of them, and actually get things done. That's a hard problem, and we're solving it from the operating system up. You'll build the foundations that make this work: the system services that keep small models running reliably on real hardware, and the APIs that connect them to everything else. The problems are open. The hardware is real. You'll own them end to end.

Skills & QualificationYou've owned complex systems work, from architecture to hands-on implementation and debugging

Strong systems fundamentals: concurrency, resource management, API design and performance trade-offs

Experience with on-device inference, inference runtimes, device software or another resource-constrained platform. Or proof that you learn fast across all of them

You make progress without a spec, explain trade-offs clearly and change course when the data says so

You question familiar architectures instead of copying them

Strong programming skills and the range to use what the problem needs. E.g. Rust, Python and JavaScript

ResponsibilitiesBuild core system services, abstractions and APIs for a platform others can build on

Have small models running reliably on real hardware: memory, scheduling and resource management, all inside tight latency, battery and thermal budgets

Connect model capabilities to the platform and app layers, so they finish real tasks end to end

Decide what runs where: wearable, phone, computer or cloud, based on the task, privacy and the hardware on hand

Prototype fast, profile on real hardware across CPUs, GPUs and NPUs, and ship what works

Work side by side with software, model and hardware engineers

How we workLocation: San Francisco, we are open to remote for the right person, with regular time in person with our SF team.
