Note: The job is a remote job and is open to candidates in USA. Fuse Energy is an energy startup building an integrated energy company using technology, renewable generation, batteries, grid infrastructure, real-time power trading, and AI. The Senior Mobile Engineer will own mobile features end to end across iOS and Android, including dynamic user interfaces and consumer-facing AI features. The role involves collaborating with backend, AI, web, and design teams while helping shape product direction and maintaining a high standard of mobile craft.

Responsibilities

• Build dynamic UI. AI composes a different experience for each customer from the components you build, and there's no established pattern to follow
• Ship vision models that run on the device. Balcony scan to panel count, meter photo to instant quote, and fault detection that catches dangerous meter faults a human would miss
• Make AI native to the product rather than a chat window stapled to the side
• Own features end to end, from architecture through to shipped, polished UI
• Work closely with our backend and AI engineers and designers
• Set the bar for mobile craft. We care how things look and feel, not just whether they work
• Help define product direction, not just execute it. We want people who dig into the "why", not just the "how"

Skills

• 5+ years building mobile applications, deep in Swift or Kotlin with the range to work across both. You've stayed hands-on throughout
• You don't stop at the client. You've worked beneath the framework and reached into the backend
• Demonstrated ownership, able to speak to decisions you drove, not just tasks you completed
• Strong communication skills and ability to collaborate effectively across product, design, backend and web
• Genuinely AI-native. You get real leverage from agents without handing over your judgement
• We have an office in London, but we hire anywhere in the world

Benefits

• Eligibility for equity
• Biannual bonus scheme
• Fully expensed tech to match your needs
• Private health insurance
• Breakfast and dinner allowance for office-based employees
• We hire anywhere in the world
