    About Limio


    Limio is on a mission to enable Go-To-Market teams to accelerate revenue by optimising every sales channel. Online, through partners, sales teams or AI agents, Limio makes omnichannel commerce simple. Limio is a startup founded by Amaury de Closset and Daniel Morton (GoCardless, Zuora, BCG, Three) and backed by leading founders and angels. We count OpenText, The Economist, and Employ as customers.

    We're looking for a Senior Full-Stack Engineer to join our Technology team to champion good development practices, increase team productivity and tackle the most exciting challenges. Limio, a growing startup, values hands‑on engagement from our developers. Expect to contribute directly, ship code, and be passionate about creating a meaningful impact working within a close‑knit team.

    The Opportunity


    We're looking for a Senior Full-Stack Engineer to own and drive the architecture of our core product. This is a hands‑on opportunity to shape the future of our platform. You'll collaborate closely with other full‑stack engineers, offering mentorship to junior team members and lead the way in resolving intricate back‑end challenges that shape our future.

    We are excited about the possibilities of AI and use it as a productivity enhancer and in the software lifecycle. We use tools such as co‑pilot, cursor, codex, claude code and coderabbit everyday. As a Senior Engineer you will be responsible for further AI adoption to improve developer efficiency, as well as incorporating AI into our products.

    What You'll Be Doing


    Collaboration & Mentorship

    • Set the direction for coding standards for the team
    • Lead by example in PR reviews, pair programming, and design sessions

    • Champion best practices for using AI to enhance code quality, review cycles, and overall software development lifecycle.
    • Figure out new use cases for AI and push the team to be on the cutting edge of AI possibilities. Experimentation with AI is actively encouraged.

    Customer‑Centric Development

    • Collaborate with Product and Customer Success to build features that matter
    • Create technical documentation that is engaging for developers
    • Support customer onboarding and adoption of new frameworks with technical expertise
    • Contribute to customer support when needed – yes, even our CEO and CTO do

    • Frontend: React, Typescript

    • Strong architectural instincts and a track record of setting technical direction
    • The ability to write clear technical documentation and thoughtful design docs
    • A bias for action and the confidence to work autonomously on complex problems
    • A natural appetite to help and mentor others, thinking of yourself as an enabler as much as a doer
    • Experience working in fast-paced environments (startups, scale-ups, or lean teams)

    Bonus Points

    • Experience building AI features and the technical infrastructure supporting it

    Why Join Limio?
