Full Stack developer, Software Product (AI)

About Nothing

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 Team

The AI & Services team is where we stop improving existing things and start inventing what’s missing. We are the studio within the machine, tasked with exploring the bleeding edge of human-computer interaction. We don't just build websites; we build intelligence that feels alive. We are working to make tech feel less like a tool and more like a companion. This is a space for high-speed experimentation, where we prototype relentlessly to find the "magic" before scaling it to millions of users globally. If you want to build the future of how people talk to their devices, this is where it happens.

What You'll Do

•
Rapidly prototype and ship novel AI interfaces—from chat and voice to multi-modal interactions—that define the next generation of the Nothing OS experience.

•
Translate wild, experimental concepts into robust, production-grade full-stack applications using Next.js, React, and Node/Python.

•
Optimise the "feel" of AI; you will obsess over latency, real-time performance, and the micro-interactions that make a digital assistant feel responsive and human.

•
Define and architect the underlying patterns and frameworks that power our AI service layer, ensuring our experimental code can scale to a global user base.

•
Work directly with hardware and OS teams to blur the lines between web, mobile, and embedded surfaces, creating a seamless continuity across devices.

•
Collaborate with Product Designers to invent entirely new interaction models, moving beyond the traditional screen-tap paradigm.

•
Manage your own deployment pipelines and infrastructure choices, ensuring we maintain a high velocity of shipping without breaking production.

What We're Looking For

•
Deep Product Pragmatism: You have a bias toward shipping. You understand that a working prototype in a user's hands is worth infinitely more than perfect code on your local machine.

•
Technical Excellence: You bring battle-hardened experience with React and Next.js, backed by strong backend skills in Node.js or Python. You know your way around microservices and cloud-native infrastructure.

•
A Drive to Own It: You are comfortable working in ambiguity. You don't wait for a ticket to be defined; you see the goal, grab the necessary API keys, and build the solution.

•
AI Fluency: You have hands-on experience or a deep curiosity for APIs, MCPs, LLMs, and vector databases. You understand the unique constraints of building with non-deterministic models.

•
Design Sensibility: You care deeply about how things look and feel. You understand that in consumer tech, the quality of the animation is just as important as the quality of the algorithm.

•
Cross-Platform Mindset: You can think outside the browser, understanding how web technologies can drive experiences on mobile and embedded systems.

•
Curiosity: You are constantly playing with new tools (RAG systems, agents) not because you have to, but because you want to see what they can do.

How We Work

We build better tech by moving fast. That speed demands direct collaboration and shared creative energy. We believe the best work happens when we're together.

•
Location: London (Kings Cross & Farringdon offices).

•
Working Pattern: This is a full-time, in-office role (5 days a week). We move fast, and that means being physically present. We design flexibility around personal needs, but we focus on the magic that sparks when we’re all in the same room.

•
Commute: We ask that you live within a 60-minute commute of your home office location.
