## The Role

We are hiring a Software Engineer (B2B Lending & Payments) to take ownership of the financial infrastructure that powers how our clients finance their assets through INFINIT. We believe the most resilient lending and payment systems are built by engineers who operate at the intersection of deep technical mastery, genuine product judgment, and direct proximity to the client’s financing workflow. This is not a ticket-execution role. You will work with business stakeholders and clients to understand why a problem matters before deciding what to build then use agentic coding to ship the how fast and well. Partnering with other engineers owning this domain, you will own two deeply connected responsibilities. First, crafting the best possible experience for a client going through a loan application, from the moment they submit a request to the moment financing is confirmed, every step should feel clear, fast, and trustworthy. Second, ensuring that every payment executed throughout the loan lifecycle (interest accruals, supplier disbursements, reimbursement) is processed correctly, securely, and without exception. Third, supporting the physical audit and due diligence workflows that allow us to maintain control over the collateral throughout the life of the loan. You will be the person the rest of the team pings when something in this domain breaks.

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, loan origination, and payment execution and the cost of getting any of it wrong.

- 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.
- Flexible Benefits: Access Flexible Retribution benefits through a convenient mobile app
- Health and Well-being: Your health matters to us. You will have access to top-quality Medical & Mental Health Insurance
- Coporoate gym discount
- 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.
- Birthday 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 our Paris office and 2 days at home.
