Job summary

Nothing is building a new kind of technology company focused on design, emotion, and human creativity at the heart of products. We’re hiring in San Francisco with remote options for the right candidate, offering a compelling base salary and competitive compensation.

You will own core system services, run small models on real hardware, and connect capabilities across platform and app layers. You’ll work closely with software, model, and hardware engineers across devices and cloud.

Qualifications

• Experience delivering complex systems from architecture to implementation.
• Strong fundamentals in concurrency and resource management.
• Experience with on-device inference or constrained platforms.
• Ability to explain trade-offs and iterate without a fixed spec.

Responsibilities

• Build core system services, abstractions and APIs for a platform others can build on.
• Ensure small models run reliably on real hardware within latency, battery and thermal budgets.
• Connect model capabilities to platform and app layers to complete end-to-end tasks.
• Decide deployment across wearable, phone, computer or cloud based on task and hardware.

Job description

Nothing 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 role

AI 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.

What you'll do

• Build 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

What you'll bring

• You’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

Nice to have

NPUs or other accelerators, embedded or OS platforms, developer-facing APIs and SDKs. Model optimization, such as quantization, is a bonus. Android experience helps, but deep AOSP knowledge isn't required. Neither is a research background. This role is about building the system.

Location

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

Nothing offers excellent benefits and competitive compensation packages. The base salary pay range for this role is $164,000 - 248,000 USD. Qurrent is an equal opportunity employer and is committed to inclusion, diversity, and equity in the workplace.
