Senior Fullstack Engineer

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.

Please note: applications will not be reviewed before 3rd January 2026 as our team will be taking a well-deserved break for the end of year celebrations.

Please take your time before applying and review the application tips carefully.

Transparency is important to us so we also wanted to share some insights about what we're looking for in applications to ensure you can set yourself up for success

Some of the key reasons why previous candidates didn't make it past the application screening stage include:

CV writing and content: it was very clear that many of the CVs we saw were very generic and AI generated. There is no issue with leveraging AI to help with CV writing, there was little indication of what real impact the candidates had in their previous experience. You might have heard of the "Achieved X, as measured by Y, by doing Z" formula (credit Laszlo Bock ~2014), this is a great way to give a clear picture of what you have actually worked on. A link to the company websites of your previous roles is also a huge help
Application care: every single application we receive is reviewed by a human (yes, hundreds of them) because we believe that candidates' efforts should be matched by an equal level of human care. This means that we expect a similar level of attention put into your application. Read and answer the application questions carefully, they make a huge difference in our decision-making process
Profile to role fit: this is a very unique Software Engineering role for our Demo experience team. We require solid experience working across the full stack and aligning with non-technical colleagues such as Sales professionals. Previous candidates have grossly underestimated this aspect of the role and failed because they were looking for very niche backend-focused, specialised payment systems work removed from business interactions. Do not apply if this is what you're looking for or if you can't demonstrate relevant experience
