Senior AI Engineer

London, England, United Kingdom
Who we are
 
Nothing exists to make tech feel exciting again.
 
We’re building a different kind of company, one that puts design, emotion, and human creativity at the heart of everything we do. From the way our products look to how they sound, feel, and function, we care about the details that make technology not just useful, but inspiring.
 
This is a place for the curious. The creators. The ones who ask why not and mean it. If you're drawn to bold ideas, fast moves, and work that actually makes you feel something, you’ll fit right in.
 
We're not here to follow the rules. We're here to make better ones.
 
About Nothing
 
Founded in London in 2020, Nothing is a design-led tech company building an alternative to the industry giants. Our products – from award-winning smartphones to expressive audio and wearables – blend iconic design with intuitive engineering to put people and creativity back at the centre of consumer tech.
 
Backed by GV (Google Ventures), EQT Ventures, C Ventures, and influential investors like Tony Fadell (iPod), Casey Neistat, and Kevin Lin (Twitch), we’ve grown from startup to global challenger in just a few years.
 

The Role:

We’re looking for a **Senior AI Engineer** to help us reimagine what mobile AI can be. This isn’t about bolting models onto apps. It’s about designing, prototyping, and building experiences that feel new—where AI is less a feature and more a living part of the product. You’ll join a small, design-oriented research and development team. We like people who are curious, product-minded, and a little restless—people who want to break the mould and try things that haven’t been done before. One week you might be experimenting with speech recognition or generative sound; the next, building a service that scales to millions. You’ll own projects end to end, obsessing over details and making sure the work doesn’t just function but feels right.

Responsibilities:

  • Leverage the latest technologies to build transformative experiences across our portfolio of devices 
  • Ideate, build and iterate quickly on projects that span speech recognition, sound and  image generation, behavioural understanding and data collection at scale
  • Develop and fine-tune models to power cloud and on-device AI functionalities
  • Use the latest AI technologies to create transformative experiences across our devices
  • Take full ownership of projects, from concept to production, with an obsession for getting the details right

Requirements:

  • Strong track record shipping AI-powered features in fast-paced, high-growth environments
  • Have worked as a Software Engineer in a high-growth, fast-paced environment 
  • A generalist mindset: you’re comfortable moving across the stack, from mobile apps to APIs to backend services
  • Bachelor degree or above, major in computer science, software engineering, artificial intelligence or related fields, with proven experience of hands-on development
  • Deep curiosity about large language models (LLMs) and excitement to integrate them into mobile experiences
  • An eye for design and user experience, and the ability to work closely with designers to craft intuitive products
We’re at the very beginning of what AI can mean on personal devices, and we want builders who see that as an opportunity to shape the future. If you’re excited to work in a place where ideas move fast, details matter, and design and engineering meet in unexpected ways, we’d love to hear from you. Tell us what you’ve built, what excites you about AI, and how you’d like to push the boundaries with us.
 
 
What we offer
  • A chance to shape the voice of one of the most exciting tech brands
  • Fast-paced and creative environment with global reach
  • A culture that values curiosity, creativity, and doing things differently
  • A commitment to building a diverse, inclusive, and welcoming workplace for all
