Remote Back-End Engineer (Senior, FinTech / Kotlin, Spring / LATAM, Europe)#25903

About the Position

We are seeking a Remote Back-End Engineer (Senior, FinTech / Kotlin, Spring / LATAM, Europe)#25903 to join our team. This role is focused on supporting projects that prepare our systems for AI integration. You will be working on building out new services and refactoring older systems.

Project Description

We are unveiling the intricacies of the largest financial market in the world: structured finance. This $16+ trillion market serves as the foundation for essential activities that promote financial freedom, such as consolidating credit card debt, refinancing student loans, purchasing homes, and launching small businesses.

Our data analytics platform delivers exceptional transparency into investment performance and risk for lenders and Wall Street investors involved in structured products. As a data-driven organization, we effectively manage critical loan data and develop modern analytical tools that empower strategic decision-making for responsible lending. In essence, we are committed to preventing a recurrence of the 2008 global financial crisis by providing the data and tools necessary for informed, data-driven decisions, contributing to a safer financial landscape for everyone.

Responsibilities

• Contribute to new code and infrastructure: Build a new service that connects our Deal Data Layer to our products. The Deals Service may include integrations across multiple services. In addition, old systems will need to transition to the new service and support existing workflows in parallel, enabling backwards compatibility.
• Upgrade existing services and monolith: Manage and upgrade systems, ensuring backward compatibility and minimal service disruption. Integrate new services with various existing systems.
• Collaborate across engineering teams: Work with frontend, data, and cloud engineers to coordinate upgrades and validate that services remain stable, performant, and compliant.
• Follow best practices for testing and monitoring: Integrate testing best practices into all work. Ensure tests are well written and resilient. Integrate monitoring and observability into everything you build.

Requirements

• Kotlin + Spring (highest priority): Candidates should be hands-on and comfortable building production services using Spring. We’re specifically looking for more than surface-level familiarity. They should understand how Spring works under the hood (dependency injection, transaction management, performance considerations, etc.), not just how to use it.
• General JVM/Backend Fundamentals (equally critical): Strong understanding of JVM internals and performance. Solid experience with databases (querying, indexing, performance tuning). Ability to design and debug distributed systems.

Nice to Have

• Scala (secondary priority): Candidates should have working familiarity and be comfortable navigating and contributing to Scala codebases.
• Systems Design, JavaScript, TypeScript, React, Web components, FrontEnd microservices

We Offer

• Work your way: Enjoy the freedom to work from anywhere, with flexible hours that match your natural rhythm.
• Plenty of time to recharge: Take 15 paid vacation days, 10 additional unpaid days if needed, plus all national holidays.
• Meaningful, long-term projects: Dive into exciting 1–5+ year projects using the latest in AI, cloud, and more.
• Support beyond the job: We help cover things like advanced language courses, gym memberships, and mentorship programs to help you grow.
• Work with global clients: Collaborate directly with international teams to create real impact.
• Make extra cash: Earn bonuses for referring great people or bringing in new business opportunities.
• Great people, no micromanagement: Join a supportive, results-focused team where you’re trusted to do your best work.
