Job description

Senior Software Engineer - Java

Would you like to be part of the journey in one of Europes fastest growing fintechs?

About Mynt

Mynt is an all-in-one corporate card and spend management platform on a mission to reinvent business banking. By combining smart software with cards and payments infrastructure, we remove manual, time-consuming admin from how companies manage spending.

We’re growing fast across the Nordics and have secured significant funding to support our continued expansion in Sweden and internationally.

Mynt is a tech‑first, product‑driven company where teams are empowered to solve real problems and build things that matter. We’re a licensed e‑money institution, card issuer, and payment processor, operating under the supervision of the Swedish Financial Supervisory Authority. Through strong partnerships with leading players such as Fortnox and Nordea — and many more on the way — our solutions are now live across all Nordic countries.

Joining Mynt means helping shape both a category‑defining product and a company that’s still early in its journey. With 100+ colleagues (and growing), we’re building teams that value ownership, momentum, and customer impact.

About the Role

We are looking for talented developers who are passionate about building high-quality software and enjoy working in an entrepreneurial environment where you can truly influence both the product and the company’s direction.

At Mynt, you will work in a modern codebase using the latest technologies, with a high level of ownership and responsibility from day one.

You will join an ambitious and experienced team with backgrounds in scale‑ups, finance, and consulting. We work in agile sprints, combining close collaboration with a strong sense of individual autonomy.

As a Backend Developer, you will focus on building robust business logic and scalable APIs for both web and mobile applications, working closely with product managers in each domain. Our development process is rooted in agile principles, clean code, and CI/CD. Testing, TDD, and automation are integral parts of how we ensure quality and maintain speed.

You will also contribute to architectural decisions and have the opportunity to help shape and build new products from an early stage, using technologies such as Java, MongoDB, MySQL, Redis, AWS, Docker, and CircleCI.

Qualifications

• Bachelor’s degree in Engineering, Computer Science, or equivalent experience
• At least 1+ years of experience in backend development using Java
• Ability to write clean, maintainable, and well-documented code
• A collaborative mindset with a passion for solving problems as part of a team
• Fluent in Swedish and English

What we can offer you

• Be part of an amazing team in a fast-growing scale-up.
• Work closely with a fun, high-performing team.
• Enjoy a flexible working environment with a great office location in central Stockholm.
• Shape your own development and responsibilities based on your passion and interest.

Our Values

• Solve for the customer
• Take ownership
• Create lasting impact
• Do it together
• Have fun
