Time to grow. Time to thrive.
We are Nmbrs. We build smart business software that removes unnecessary complexity for SMEs and the professionals who support them. Nmbrs brings together four established product organisations—Payroll, Accounting, Invoicing and Reporting—with teams across the Netherlands, Sweden and Portugal.
We are one brand with a shared ambition, while continuing to work from the expertise and strengths of our individual organisations. We join forces where it makes sense, while keeping teams, expertise and decision-making close together.
For this role, you’ll join Nmbrs Payroll in Lisbon, working closely with the colleagues in your local team while being part of the wider Nmbrs organisation.
As a ML Engineer, you’ll play a pivotal part in building advanced machine learning solutions. Ranging from salary benchmarking and predictive analytics to anomaly detection, all leveraging our extensive payroll data. Your work will help drive Nmbrs toward our vision of a self-driving payroll application.

The success of a business depends on the well-being of the people that choose to work for it. And because employee satisfaction greatly relies on the smooth operation of HR processes, we’ve developed smart cloud software that makes the daily work of all involved professionals easier. By trusting our software to take care of their processes, they can take care of their people.
What makes our product unique is that it integrates both HR and payroll processes in one seamless workflow, and allows employees to have all their HR needs at their fingertips in one intuitive mobile app. Our technology automates many repetitive tasks and delegates those that require manual input directly to the people that can best supply it. With Nmbrs, HR managers, payroll professionals, accountants, and employees can collaborate in a way that reduces errors and saves everyone valuable time.
We believe that the time saved with our products is best spent on growth. We get excited when we see accountants make their businesses grow by servicing more and larger customers. And when HR departments can grow their ambitions. But ultimately, we do this for the employees. Our mission succeeds when all the people in the workplace not just get their payslips in time but also get the attention they deserve to achieve personal and professional growth.
Our vision for employee well-being transcends beyond our software. From the day we launched our company, we’ve practiced what we preach by setting the same high standards for our workplace as we’ve done for our products. With self-directing teams in three European cities, we’re inclusively collaborating across cultures. We believe this makes Nmbrs a great company to work for – and work with.
