Our Mission

About 5% of supply chain emissions are a result of last-mile logistics and transportation, and as e-commerce booms, emissions are set to increase by more than 32% in the top 100 cities globally.

We are on a mission to become the largest ecosystem of sustainable vehicles in the world; by enabling the electrification of commercial fleets in Europe by connecting fleet operators and service providers in one platform.

Our Values

Move fast: Done is better than perfect.

  • We work on small iterations: Learn, build, test, monitor and repeat
  • The planet needs action now
  • We lead change in our industry
  • There is no better timing than now to execute our vision, but the window is short

Be passionate and purposeful: Deeply care about everything we do.

  • Believe in our mission, for a better future. Believe in tech for good, let’s have an impact together
  • Be obsessed with our product, customers and industry
  • Be part of something that matters

Strong opinions loosely held.

  • Speak up, be opinionated but listen and stay open
  • We are building this together

We win and lose together.

  • We optimise for the success of our mission rather than ourselves
  • We empower each other
  • We value transparency and being straightforward
  • We don’t like egos
  • You succeed with Papaya

Have fun: Enjoy the ride!

  • We are a group of friends solving big challenges
  • We celebrate our success
  • We learn from our failures
  • We come to work through choice not a necessity
  • We don’t take ourselves too seriously
  • We make our products fun

The Role

We are seeking a highly motivated and experienced front-end lead developer to join us.

As we strive to provide our customers with a "World-class product experience", you will have the opportunity to shape the user experience and interface of our products, ensuring they are intuitive, visually appealing, and highly functional.

This is a position that requires both technical expertise and strong mentoring abilities to guide and support less experienced developers in their professional growth.


  • Collaborate within a cross-functional team, including back-end developers, designers, and product managers, to design elegant and user-friendly solutions
  • Build and ship features our customers will love
  • Our customers are at the heart of our product; you will have the chance to listen to and understand real-time customer feedback and turn it into valuable features
  • Mentor and guide less experienced developers, providing technical support, code reviews, and constructive feedback to help them improve their skills and grow professionally
  • Architect, develop and maintain scalable, modular, and reusable front-end components and libraries
  • Stay up to date with industry trends and emerging technologies, and provide recommendations on incorporating new tools and frameworks into our development process
  • Experience with responsive design, cross-browser compatibility, and performance optimization is a plus
  • Familiarity with back-end technologies (e.g. Node.js, Ruby) is a plus
  • Be a self-starter and able to work independently, whilst also being a team player

Our Tech Stack 💻

We like to keep it simple and use the right tool for the right time so it is likely to change, but currently, we are using:

    • React
    • TypeScript
    • NextJS
    • Vercel / Cloudflare
    • Ruby on Rails API - REST and GraphQL
    • PostgresQL
    • Redis
    • AWS / Heroku
