Senior Frontend Engineer (Accounting Integrations)

Pleo • Lisbon, NY

About The Position

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.
About the role
We’re looking for a Senior Frontend Engineer to join our Accounting Experience (AX) team at Pleo. In this role, you’ll help us build reliable, high-quality accounting experiences that customers trust: exporting, reporting, and accounting setup flows that need to be correct, debuggable, and easy to evolve. If you enjoy owning complex user journeys end-to-end, collaborating tightly with product and backend, and raising the quality bar for a critical domain, this is the opportunity for you.

Requirements

• Strong experience building and maintaining complex React + TypeScript applications in production
• A systems mindset for frontend: you design state models, failure modes, and recovery paths, not just screens
• Solid product judgment and communication skills, especially when aligning trade-offs with engineers and non-engineering stakeholders
• A track record of improving quality and operability through testing, observability, and good debugging practices
• Comfort working in domains where correctness matters (e.g., fintech, accounting, compliance-heavy B2B)
• The willingness to mentor others and share knowledge in a way that scales the team

Responsibilities

• Own end-to-end delivery of frontend work in finance-critical flows (reporting, exports, accounting setup), from discovery through release and follow-up
• Drive frontend architecture decisions for complex stateful experiences (e.g., async job flows, progress and error states, etc)
• Partner with backend engineers to shape clear contracts that make the UI resilient and supportable in production
• Raise the quality bar through pragmatic testing, predictable state management, and strong PR hygiene to reduce regressions and rework
• Collaborate closely with product, design, and domain experts to validate edge cases and semantics early
• Mentor and support other engineers by sharing patterns, reviewing code with context, and making the “right way” the easy way

Benefits

• Your own Pleo card (no more out-of-pocket spending!)
• Lunch is on us for your work days - enjoy catered meals or receive a lunch allowance based on your local office
• Comprehensive private healthcare - depending on your location, coverage options include Vitality, Alan or Médis
• We offer 25 days of holiday + your public holidays
• For our Team, we offer both hybrid and fully remote working options
• Option to purchase 5 additional days of holiday through a salary sacrifice
• We use MyndUp to give our employees access to free mental health and well-being support with great success so far
• 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
