About Nanogram

Nanogram is a TikTok-style mobile feed where every item is a short, AI-generated browser game - anyone can make one from a prompt.

The role

You'll turn specs into finished mobile screens, fast. We have a design system and a component toolbox; specs come in from product and screens go out to engineers - pixel-perfect Figma with every state (empty, error, offline, loading), built so a Sofia engineer can implement without asking a question. Throughput and cleanliness are the job.

This isn't a design-lead role - you'll work inside the system rather than inventing one, and there's no team under you. It's also not a brand or marketing design role, not UX research, and not game art (the games themselves are generated; this is the app around them). A strong mid-level designer who wants to execute beats a senior who wants to direct.

What you'll do

  • Turn product specs into pixel-perfect Figma screens, fast.

  • Design every state of a screen - empty, error, offline, loading - not just the happy path.

  • Build screens with auto-layout, components and variants that a Sofia engineer can implement without back-and-forth.

  • Work inside our existing design system and component toolbox.

What you bring

  • Mobile app design first: iOS/Android consumer apps, ideally social, short-form or gaming.

  • Fluent in HIG and Material without being religious about either.

  • Strong mid-level operator, not a design lead - productive from day one inside an existing system.

  • Fast, clean Figma execution: spec to pixel-perfect screens with all states, using auto-layout, components and variants.

  • A portfolio showing full flows, not just hero shots.

  • At least one stretch at a product company, not only agencies.

  • Roughly 3-5 years of experience.

Nice to have

  • Motion and micro-interactions (Rive, Lottie, After Effects).

  • Game UI/HUD work.

  • Icon and illustration ability.

  • Comfortable with AI image tools for artwork.

  • Basic prototyping.

  • Gaming background.

Logistics

  • Location: Sofia, in person, from day one. This isn't flexible - you'll sit with core engineering.

  • Full-time.

  • Compensation: base + equity.
