[Hiring] Applied AI Engineer @Nothing Technology

Role Description

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. Your job: turn what models can do into agents that get real things done for people.

It's hands-on and backend-first, and full-stack when it needs to be. One week you're prototyping something new. The next, you're making it reliable enough to ship. We're open on seniority; what matters is what you've built, how you think, and how fast you learn.

What you'll do

• Build agents that use tools, data, and app capabilities to finish real tasks
• Build the backend they run on: services, APIs, storage, and sync between devices and the cloud
• Solve the hard backend problems: concurrency, state, and data flow across services and devices
• Work with our on-device AI and systems engineers to plug agents into the platform
• Write evals against real tasks, chase down every failure, and ship the fix
• Own the task end to end, frontend included
• Build with coding agents every day, and know when your own judgment should win

Qualifications

• You've shipped working software: at a job, in your own projects, or in open source
• A backend-first mindset: services, APIs, concurrency, storage, and how data moves through a system
• You've built with LLMs or agents, or can show us you'd pick them up fast and use them on a real problem
• You can take a vague idea and turn it into something that works
• You learn by building, testing, and breaking things
• You like small teams where everyone builds

Requirements

• Shipped agent products, full-stack products, or distributed backend systems
• Python, JavaScript/TypeScript, and Rust are all relevant, but strong fundamentals matter more than a list of frameworks

Benefits

• Excellent benefits
• Competitive compensation packages
• Base salary pay range for this role is $159,000–$242,000 USD
