Job description

At Liberis, we are on a mission to unleash the power of small businesses all over the world – delivering the financial products they need to grow through a network of global partners.

At its core, Liberis is a technology‑driven company, bridging the gap between finance and small businesses. We use data and insights to help partners understand their customers’ real‑time needs and tech to offer tailor‑made financial products. Empowering small businesses to grow and keep their independent spirit alive is central to our vision.

Since 2007, Liberis has funded over 50,000 small businesses with over $3bn – but we believe there is much more to be done. Learn more about Liberis by visiting https://www.liberis.com/.

The role

At Liberis, we’re building a global engineering team that thrives on autonomy, ownership, and impact. Our engineers don’t just write code – they solve real‑world problems for small businesses, shaping products that unlock opportunity at scale. We believe in empowering teams to make decisions, move fast, and take full responsibility for the solutions they deliver. You’ll join a team where curiosity is encouraged, experimentation is celebrated, and collaboration across Product, Data, and Engineering is the norm.

As a Senior Engineer, you will be a key mentor to other members of the Engineering team – supporting us to continually develop and push the boundaries of what a scaling, multi‑product FinTech organisation can achieve.

The interview process

• Screening call with Chess (Internal Recruiter) (30 mins)
• Video interview with the Hiring Manager (45 mins)
• In‑person code‑pairing interview with a member of Engineering team (1 hour)
• Video interview with the wider Liberis team (1 hour)

What We Think You’ll Need

• Proven success writing code in two or more programming languages.
• Willingness to learn our tech stack – mostly C# .net, Node, and React.
• Proven experience developing APIs and services.
• Understanding of working with Agile methods, such as Extreme Programming, Kanban, or Scrum.
• Experience mentoring more junior team members.
• Resilience in early‑stage business situations, where requirements are evolving and experimentation is required.
• Bonus points if you have experience with cloud technologies (we are moving to GCP); experience using highly collaborative methods such as ensemble, mob, or pair programming; experience writing financial software; or experience with Test‑Driven Development.

N.B. – there is an ‘on‑call’ element to this role, which Chess will outline at the screening stage.

If this opportunity feels like the right fit for your next career move, we’d love to hear from you!

Our hybrid approach

At Liberis, we embrace flexibility as a core part of our culture, while also valuing the importance of the time our teams spend together in the office.
