Skills
Must have
- 5+ years building and running production software, having owned something from problem statement to production
- Comfortable working across the full stack, not precious about which layer
- Strong in TypeScript and modern backend architecture, conceptually
- Care about how things are built as well as whether they work
- Can talk to non-technical stakeholders without a PM in the room
- At ease working fully remotely and takes initiative to stay close to people
- English is the working language of this role
Nice to have
- Think like an owner: started, run or helped build something of your own
- Shipped a React Native app that real people used every day
- Worked in an operations-heavy business (field service, logistics, industrial, energy)
- Put AI-driven workflows into production
- Built internal tooling, codegen or developer-experience work other engineers adopted
- Worked with IoT, telemetry or time-series data at scale

Senior Fullstack Engineer (F/M/X)
Full remote — Europe · Product & Engineering
Who are we?
In 2017, after more than ten years in the lift industry across Europe and Asia, Benoît Dupont noticed a system stuck in its ways where speed takes priority over quality and frontline teams remain invisible.
With Jade Francine, he founded WeMaintain to put technology, trust and people back at the heart of building maintenance. Their ambition: give technicians back their autonomy, rely on in-house IoT technology, and deliver a service designed for users and clients.
Based in Paris, London, Singapore and Hong Kong, we maintain lifts, escalators, automatic doors and fire safety systems. With 350+ employees, we combine on-the-ground expertise with data-driven management to deliver maintenance that is high-performing, transparent and sustainable.
In April 2026, Otis, the world's largest elevator and escalator company, became our majority shareholder. We keep running as we always have: same team, same brand, same mission. What changes is the scale of what we can go after, and the means behind us to do it.
We don't just maintain buildings. We transform how they're operated.
Why join us
Because here, you don't have to choose between impact and stability.
Large groups often offer stability, but little room to manoeuvre. Smaller organisations allow more freedom, but sometimes without clear direction.
At WeMaintain, we strike the right balance:
- Real autonomy, with modern tools and strong support
- A culture built on trust, transparency and respect
- Genuine opportunities for growth and internal mobility
- A team that values commitment, perseverance and the drive to make things happen
And our values guide us every day:
- Care: Working with respect and kindness, internally as well as with our customers
- Grit: Seeing things through, with high standards and determination
- Uniqueness: Daring to be yourself, sharing your ideas and challenging the status quo
Who we're looking for
We're looking for a Senior Fullstack Engineer who wants to own problems, not tickets.
You get handed a problem before anyone has decided what the answer should be. You help our product managers shape it, you build it, and you take it to production. The whole arc is yours. That suits people who like to argue about what gets built. It would frustrates people who would rather receive a groomed backlog and a clear spec, and people who would rather be left alone to code.
