Software Engineer (Full-stack AI) London · Old Street · Onsite (5 days/week)
Hey, we're Skippr AI. Your new interface is an agent. We build an AI agent, led by voice and vision, that operates software for people: they just ask, and it onboards them, guides them, and does the work. Drop it into your product with two lines of code and every user gets a live agent on day one. The same agent shows up wherever your users are — embedded in your product, in the meeting room, or across your team's tools. We're a small, 100% AI-native team in Old Street, London, backed by Bessemer Venture Partners, Moonfire, and angels from Google, Twilio, and Meta. We don't just build agents — we use AI to optimise our own work every single day. If that sounds like your kind of problem, we should talk.
What you'll do
- Modern stack: Build scalable, real-time systems. We value diverse backgrounds and skills — some experience with a modern stack like ours (Hono, React, Neon, TypeScript, Python) or with AI-powered apps and agents is beneficial, but it isn't a strict requirement.
- Own features end-to-end: From intuitive user interfaces to scalable backend services and AI agent orchestration.
- Agentic experience: Shape an intuitive experience for a voice-first agent, and build the system behind it — tool use MCP, memory, and real-time voice & vision.
- Work closely with the founders: Shape and build our vision, balancing moving fast now with scaling later.
This role is for you if
- You have at least 4 years of experience as a software engineer.
- You're a 0→1 builder who has shipped to production — ideally rapidly shipping apps and building scalable systems in containerised environments.
- You have at least 2 years of experience in a startup.
- You know what it means to build something from scratch that real people actually use or pay for.
- You use coding agent tools like Claude Code or Codex as your daily driver.
- You thrive in ambiguity. You can juggle shifting priorities, and decide when to let small fires burn and when to dive in.
This role is not for you if
- You want remote or hybrid work. We believe early-stage startups win by moving fast in the same room — this is an in-office role, five days a week in our Old Street office.
- You dislike ambiguity. Priorities shift, experiments fail, and new opportunities appear. If you prefer stable roadmaps, this isn't the place.
- You don't enjoy 0→1 environments. Early-stage means wearing multiple hats, solving unscoped problems, and building with imperfect information.
What we offer
- Competitive salary plus meaningful equity (EMI options): Everyone here has skin in the game and upside if we win.
- The chance to define entirely new markets for AI agents.
- Real influence on architecture: You'll make foundational decisions on our platform and SDK that shape how future engineers and customers build on top of it.
- Exposure across the startup stack: Beyond code — sit in on user interviews, shape product strategy, and get a front-row seat to how startups actually grow.
- Comprehensive benefits: Pension, private health insurance, and 25 days holiday plus bank holidays.
- A team that's genuinely excited: We're obsessive about the problem, love what we're building, and keep the culture sharp but supportive.
