Senior Frontend Engineer (Accounting Integrations)
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.
What you’ll be doing
As a Senior Frontend Engineer, you will:
- 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
To put things into context, our roadmap includes work like scaling export/reporting experiences (including async patterns), improving self-serve error handling, and making accounting flows more consistent and understandable. You can expect to work with the following tech stack and tools:
- Modern JavaScript, CSS and Web APIs
- Component-based, declarative UIs (we use React)
- CSS-in-JS (we use styled-components)
- Linting and testing frameworks (Vitest)
- Static types (we use TypeScript)
- Data fetching and mutations (we use tRPC, SWR)
- Grafana for observability
- LaunchDarkly for feature flagging, used to ship incrementally and decommission old paths safely
What you bring You’ll thrive in this role if you have:
- 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
Why is this role a good fit for you
This role is a good fit for you if:
- Like owning a problem space end-to-end and being trusted to drive it forward
- Enjoy turning ambiguity into clear execution plans and predictable delivery
- Care about quality, operability, and building systems that are easy to support and evolve
- Collaborate well across disciplines and communicate progress in a way that builds confidence
- Like mentoring and improving how the team works, not just shipping individual tickets
This role is not a good fit for you if:
- Prefer being handed clearly scoped tasks without needing to shape the plan
- Avoid responsibility for validation, follow-up, or production outcomes
- Dislike collaboration or treat knowledge as something to protect rather than share
- Prefer optimizing for speed at the expense of quality and long-term maintainability
We’re committed to helping you develop your career, whether that means taking on bigger projects, stepping into leadership, or acquiring new skills in engineering.
