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. ## Description 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. ## Related Videos - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Migrating half a million users to a new payment service provider](https://www.wearedevelopers.com/videos/730-migrating-half-a-million-users-to-a-new-payment-service-provider) - [AI Pair Programming with GitHub Copilot at SAP: Looking Back, Looking Forward!](https://www.wearedevelopers.com/videos/1546-ai-pair-programming-with-github-copilot-at-sap-looking-back-looking-forward) - [Next Level Enterprise Architecture: Modular, Flexible, Scalable, Multichannel and AI-Ready?](https://www.wearedevelopers.com/videos/1017-next-level-enterprise-architecture-modular-flexible-scalable-multichannel-and-ai-ready) - [Nest.js - TypeScript in the backend can also be clean](https://www.wearedevelopers.com/videos/1033-nest-js-typescript-in-the-backend-can-also-be-clean) - [Enterprise Python: Software That Lives Long And Prosper](https://www.wearedevelopers.com/videos/946-enterprise-python-software-that-lives-long-and-prosper) ## Related Articles - [Top-Paying Tech Jobs (with Salaries)](https://www.wearedevelopers.com/magazine/372-top-paying-tech-jobs-with-salaries) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Where to Find Entry-Level Software Engineering Jobs](https://www.wearedevelopers.com/magazine/397-where-to-find-entry-level-software-engineering-jobs)
