Messy spend management is tricky business. And tedious processes are a lose-lose situation for all involved, not just finance. At Pleo, we're changing that. We build spend solutions that make managing money seamless, empowering, and surprisingly effective for finance teams and employees alike - with a vision to help all businesses ‘go beyond’.

The word ‘Pleo’ actually means ‘more than you’d expect’, and living by that mantra has been the secret to our success over the last 10 years.

Now, we’re at a pivotal moment in our journey; every move we make has a direct impact on our 40,000+ customers, our business, and our collective success. We need people who take pride in uncovering customer needs, who turn complex problems into simple solutions, challenge the way things are done (respectfully), and always aim high. With great ambitions driving us forward, we can’t say we’ve got this whole thing figured out. And frankly, that’s half the fun! What we can say is that we’re a driven, progressive, and, importantly, a kind bunch of 850+ people from over 100 nationalities, all committed to delivering the future of business spending, together.

Small but mighty. That’s the best way to describe our Mobile Core team. Our vision? To empower product teams to build, maintain, and monitor mobile app features with an eye for quality, consistency and scale. How does that sound?

We’re looking for a Senior Engineer with a passion for technical excellence and a knack for crafting ambitious, forward-thinking strategies. If you thrive on enabling fellow engineers through a rock-solid, innovative platform, we’d love to hear from you!

If you’re excited to play with hot reload in React Native instead of recompiling your builds? Come on over!

If we said, iOS or Android, and you said “yes”, you’re the one that we want (ooh ooh ooh 🎶)!

Our app stands on a solid foundation, but we’re looking for a Senior Engineer who can reinforce and future-proof it while embracing opportunities to innovate. Bring us your unique insights, deep technical know-how, and strategic thinking, and we promise a supportive, growth-oriented environment filled with awesome humans.

The nitty gritty skills you’ll need

  • You have experience developing and maintaining React Native mobile apps

  • You're strong in TypeScript

  • You’re familiar with the Backend-for-Frontend (BFF) design pattern

  • You have hands on experience building native mobile apps for iOS and/or Android

  • You have proficiency with CI/CD processes and tools such as Fastlane or Github Actions

  • You have experience building quality apps with the trending E2E testing frameworks (Maestro/Detox/Jest)

  • A deep understanding of current industry trends and best practices

  • Demonstrated ability to define and drive a technical strategy for a platform team

We'll geek out if you

  • Have a strong grasp of testing tools and automation

  • Believe in quality and maintainability over quick fixes

  • Stay ahead of the curve, continuously exploring the latest tools and techniques

Your colleagues say you:

  • Bring a strong problem-solving mindset and thrive on tackling complex challenges at scale

  • Enjoy coaching others and helping them grow as engineers

  • Are motivated by a strong passion to learn and continuously improve

  • Bring a positive, welcoming attitude - you’re someone that they’d love to grab a coffee with (virtual or not!)

  • Work in English with ease (it's our company language)

Show me the benefits!

  • Your own Pleo card (no more out-of-pocket spending!)

  • Lunch is on us - with catering in our Lisbon, Copenhagen and London offices or a monthly lunch allowance paid directly together with your salary in other markets 🍜

  • Private health insurance to ensure you’re fit in body and mind to do your best work

  • In [location], we offer 25 days of holiday + your public holidays

  • We offer flexibility/remote working options

  • Option to purchase 5 additional days of holiday through a salary sacrifice

  • We’re trialing MyndUp to give our employees access to free mental health and well-being support with great success so far ❤️‍🩹

  • Access to LinkedIn Learning - acquire new skills, stay abreast of industry trends, and fuel your personal and professional development continuously

  • Paid parental leave - we want to make sure that we're supportive of families and help you feel that you don't have to compromise your family due to work 👶
