Senior Full-stack Engineer (Frontend Specialisation) - Team AI
At Pleo, we’re on a mission to revolutionise the way businesses manage company spending. No more outdated processes, clunky spreadsheets, or frustrating delays - we believe spend management should be seamless, empowering, and surprisingly effective for finance teams and employees alike. We’re creating tools that promote autonomy, foster trust, and let businesses focus on what truly matters.
Our culture is built on transparency, collaboration, and a deep commitment to innovation – which is reflected in our spending solution. At Pleo, you’ll join a passionate team shaping the future of work, all while having some fun along the way.
The Role
At Pleo, our Senior Engineers play a pivotal role in driving technical excellence within teams. What does that mean? While working closely within the AI Enablement team, you’ll spend a good portion of your time coding and hands-on problem-solving, helping to sprinkle intelligence (through Large Language Models, Machine Learning, etc.) to improve features and products across the Pleo platform. You will build technology that enables other product teams in the company to apply large language models to their problem spaces to better serve our customers.
As a Senior Engineer, you will also contribute by taking ownership of key projects and components, mentoring junior engineers, and fostering a culture of collaboration. You’ll have a significant role in improving the scalability, performance, and robustness of our platform, and will collaborate closely with product teams to deliver impactful solutions.
We’re looking for people who others can look up to for technical expertise and leadership. You’ll help shape the technical direction for the team, ensuring best practices in both code and culture.
Join our team of Pleo pioneers who thrive on scaling at pace and prioritise our customers’ needs. Help us solve complex problems with innovative solutions and a touch of magic. No expense reports. No time wasted.
What you’ll be doing
- Design, develop, and maintain scalable AI-powered products and features. There is product engineering at the heart of this. You’ll join customer calls, ideate on customer problems, come up with solutions, build and ship this to customers, and learn and iterate.
- Work closely with other product and data teams to integrate AI capabilities into our platform.
- Build and optimize robust data pipelines to support AI-driven features.
- Develop and improve the scalability, performance, and reliability of our back-end infrastructure.
- Collaborate with product managers, designers, and other engineers to define, architect, and build new customer-facing features.

- Ensure seamless integration between back-end and front-end systems and other components of the platform.
What you bring

- Experience in back-end technologies such as Node.js, Java, or Kotlin.
- Experience with relational databases such as PostgreSQL or MySQL.
- Experience with distributed systems and micro-services architecture.
- Interest or experience in AI: Application of LLMs, RAG, embeddings, vector databases, prompting, and machine learning.
Who you’ll be working with and reporting to
You’ll report to our Engineering Manager and work closely with teams in Spend Decisions. Our team of six is highly collaborative and dedicated to building AI-powered features starting with using LLMs to catch expenses that are out-of-policy. You’ll also have the chance to partner with teams across Spend Insights, Platform AI, Users & Controls, etc. to ensure success.
How you’ll develop in this role
In your first three months at Pleo, you’ll:
- Lead one of the many features we have planned for the AI powered out-of-policy checks for expenses and in so doing reduce the time it takes to review and bookkeep.
- Collaborate with the many teams across Spend Decisions and Spend Insight to improve our automation offerings with AI.
- Grow your skills in AI product engineering and feature delivery, taking on new challenges as the company continues to scale.
We’re committed to helping you develop your career, whether that means taking on bigger projects, stepping into leadership, or acquiring new skills in AI engineering.”

Why join us?
Working at Pleo means you're working on something very exciting: the future of work. Our mission is to help every company go beyond the books. Pleo itself means ‘more than you’d expect’, and it’s been the secret to our success over the last 8 years. So it’s only fitting that we’d pass this philosophy onto our customers to help them make the most of their finances.
We think company spending should be delegated to all employees and teams, that it should be as automated as possible, and that it should drive a culture of responsible spending. Finance teams shouldn’t be siloed from the rest of the organisation – they should work in unity with marketing, sales, IT and everyone else.
Speaking of working in unity, our values tell the story of how we work at Pleo. We have four core values, the first of which is ‘champion the customer’, which means we address real pain points that businesses face. Next up is ‘succeed as a team’, which highlights how our strength lies in our diversity and trust in each other. We also ‘make it happen’ by taking bold decisions and following through to deliver results. Last but not least, we ‘build to scale’, creating lasting solutions that address today’s challenges and anticipate tomorrow’s needs.
So, in a nutshell, that's Pleo. Today we are a 850+ team, from over 100 nations, sitting in our Copenhagen HQ, London, Stockholm, Berlin, Madrid, Montreal and Lisbon offices —and quite a few full-time remotes in 35 other countries! Being HQ'd out of Copenhagen means we're inspired by things like a good work-life balance. If you don't work in the office with us, we'll help you set up the best remote setup possible and make sure you still have time to connect with your team.
