Senior Fullstack Engineer

Messy spend management is tricky business. 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 Software Engineer to join our Demo Experience team at Pleo. In this role, you will enable multiple internal customers & stakeholders to experience, test and showcase Pleo and will be part of Pleo’s Platform organization. If you're excited about improving our sales demo experience and increasing our sales conversion rate, making our product development process easier, or enabling our internal partners to integrate by becoming a solid API ecosystem player, then this is the opportunity for you! You will report to our Senior Engineering Manager and work closely with teams across multiple departments, especially Go-to-market, to ensure success. Our team of four (including you) is highly collaborative and dedicated to improving and enabling the demoability of Pleo.

What You’ll Be Doing

• Lead initiatives to design, build, and maintain innovative solutions to drive efficiency across multiple departments
• Collaborate with cross‑functional teams to identify opportunities for improvement in demo, sandbox, and test accounts experience
• Participate in code reviews, post‑mortems, and provide mentorship to other engineers
• Proactively address technical debt and guide the team through technical challenges and migrations
• Contribute to the execution, delivery, and quality of projects within the team

What You Bring

• Expertise in server‑side languages, especially Kotlin, while also having experience working with Node.js and frontend technologies like React using TypeScript
• Experience with distributed systems, microservices, and cloud environments (e.g., AWS, Kubernetes)
• Proficiency with relational databases like PostgreSQL, testing frameworks (e.g., JUnit, Testcontainers), and observability tools like Grafana
• A proven ability to design and develop APIs
• Strong problem‑solving skills and a collaborative mindset to mentor and upskill your teammates
• A proven ability to lead large projects, manage ambiguity, and maintain high standards for code quality and reliability
• A proven ability to work autonomously and collaborate with non‑technical stakeholders

Why is this role a good fit for you

• You love having end‑to‑end ownership of software engineering.
• You’re keen to develop your leadership skills.
• You are impact driven and enjoy collaborating with internal users & stakeholders.

This role is not a good fit for you

• You require structured guidance from a Product Manager (this role is very autonomous).
• Interacting with business stakeholders gives you nightmares.
• You can’t balance short‑term and long‑term oriented work.

How You’ll Develop In This Role

• Lead initiatives to improve how well our commercial organization can demonstrate Pleo for prospective customers and partners, directly impacting how well they can sell our products.
• Collaborate with product teams to improve how they make sure their features and products can be demonstrated.
• Grow your full‑stack skills, taking on new challenges as the company continues to scale.
