Front End Engineer; Web Core

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.

We at Pleo are on a mission to make spend management surprisingly effective and empowering. We build a product used by thousands of companies across Europe, and our web app is a core part of that experience.

We’re hiring a Staff Engineer to join Web Core — our frontend platform team. The Web Core team exists to enable product engineers across Pleo to build and ship high-quality web software. We own the foundations of the web stack (tooling, patterns, architecture, reliability of the developer workflow), and we partner closely with product teams to make delivery faster, safer, and more consistent.

• Build and maintain a web platform that teams use to efficiently deliver excellent web experiences.

• Drive technical excellence across Pleo’s web applications (architecture, patterns, quality, performance, accessibility).

• Improve developer experience (DX) through tooling, CI reliability, and fast feedback loops.

• Steward shared web foundations (libraries, conventions, golden paths) and support adoption.

• Facilitate and contribute to the broader frontend community at Pleo.

As a Staff Engineer in Web Core, you will be a force multiplier
. You’ll work across teams and systems to remove constraints and raise the bar for how we build and run web software.

• Set technical direction for parts of our web platform, and drive alignment across teams.

• Identify the biggest leverage opportunities for web engineering at Pleo (quality, delivery speed, reliability) and execute on them.

• Partner with product engineers and leads to design solutions that fit the wider ecosystem.

• Build and evolve internal tooling, frameworks, and golden paths that scale across teams.

• Improve the reliability and usability of our CI and local developer workflows.

• Coach and mentor engineers, and help grow technical leadership in the frontend community.

• Contribute hands-on in code. This role blends strategy and execution. You should expect to be coding a meaningful part of the time.

• Building and maintaining complex web applications at scale.

• Type Script and modern frontend engineering (React experience is a plus).

• Designing maintainable systems (including frontend-facing APIs and platform boundaries).

• Testing practices and tooling (unit, integration, end-to-end) and a strong quality mindset.

• CI/CD and developer productivity improvements (faster, more reliable feedback loops).

• Observability and monitoring practices for web systems (metrics, logging, tracing, alerting).

• Working effectively across teams and stakeholders, and communicating tradeoffs clearly.
