The Role
We are hiring a Software Engineer (Core Banking & Payments) to work from our Luxembourg office and spearhead our financial infrastructure's evolution. We believe the most resilient payment systems are built by engineers who operate at the intersection of deep technical mastery and direct proximity to the customer's financial workflow.
As a Software Engineer focusing on the Core Banking and Payments domain, you will bridge the gap between our automotive dealers’ financing needs and our core banking transition. Partnering with our lead payment engineer, you will replace our current BaaS providers with a high-performance, proprietary system. You will own the technical architecture on the front lines, ensuring our technical stack delivers the precision and scale required for a regulated environment.
What do you need to be successful in this role?
- Expert C# & .NET Engineering, mastery of the .NET ecosystem with a focus on building high-performance, distributed backend systems.
- You have a proven track record of shipping scalable, production-grade architectures where technical clarity and long-term maintainability are the default.
- Core banking & ledger logic, a strong professional background in regulated financial environments. You understand the mechanics of ledgers, payment orchestration, and the complexities of migrating from BaaS providers to Core Banking Platforms.
- Mission-critical ownership: Demonstrated ability to own features end-to-end. You don't just "write code"; you analyze customer financing workflows, define rigorous technical requirements, and take full accountability for the reliability of every transaction you process.
- Highly effective stakeholder communication, capable of seamlessly translating deep technical concepts for non-technical stakeholders (customers, product managers) and clearly translating business objectives into prioritized engineering tasks.
- Practical experience leveraging modern developer tools (such as agentic coding or advanced automation techniques) to achieve significantly accelerated development velocity while rigorously upholding code quality standards.
What will you find working at INFINIT?
- Competitive Salary and Equity: We offer highly competitive salaries and a stake in our success with share options because we're building this together.
- Diverse and Inclusive Team: Join a dynamic and international team in excess of 8 nationalities. You'll have the chance to work with experienced professionals from around the world, fostering a rich learning environment.
- Inspiring Mission: We are dedicated to revolutionizing business financing and making a positive impact on the European economy. Your work at INFINIT will have a lasting effect on businesses and communities.
- Health and Well-being: Your health matters to us. You will have access to top-quality Health Insurance as well as some awesome gym membership discounts.
- Quality Time Together: We foster a sense of community with annual gatherings and bi-weekly office team gatherings. You're more than welcome to join us for quality time.
- Personal Time Off: Enjoy flexibility with your personal time off.
- Flexibility and Ownership: We trust our team and we are goal-oriented. Enjoy the flexibility of hybrid working 3 days a week in one of our Luxembourg office and 2 days at home.
