Description

Sumsub is a leading full-cycle verification platform that enables scalable compliance. From identity and business verification to ongoing monitoring, our platform adapts to different risk appetites and market demands, ensuring global compliance. It allows customizing analytics and workflows with a no-code interface. Over 4,000 clients — including Bitpanda, Wirex, Avis, Bybit, Vodafone, Duolingo, Kaizen Gaming, and TransferGo — trust Sumsub to accelerate growth, prevent fraud, and maintain compliance worldwide. Now we are looking for a Senior Backend Engineer to build the core backend of our Case Management platform. This role is an exciting opportunity to shape a central product with complex data models and high business impact. What You Will Be Doing: Design and build core backend services for the Case Management system that unifies multiple compliance and risk products. Model and implement complex domain logic for cases, signals, entities, and investigation workflows. Design data structures and APIs that allow investigators to work with large, interconnected datasets from a single interface. Build scalable backend solutions that support high data volumes and evolving product requirements. Collaborate closely with frontend, product, and other backend teams to deliver end-to-end features. Take strong ownership of backend architecture decisions and continuously improve performance and maintainability. About You: Strong experience in backend development with a focus on data-heavy and domain-rich systems. Confident in designing data models, APIs, and backend architectures for complex products. Solid understanding of databases and data access patterns (MongoDB, ClickHouse, or other SQL/NoSQL systems). Able to work autonomously, make technical decisions, and take responsibility for outcomes. Product-oriented mindset with an interest in building systems that real users rely on daily. Comfortable collaborating in a senior engineering team with shared ownership of the platform. What We Offer: Remote-first, trust-based culture. Work from the place that works best for you. No mandatory office days, no attendance trackers. In some locations, we provide offices or coworking spaces, but the choice is yours. True flexibility. We do not fix you to a 9-to-5 schedule. You can adjust your working hours when needed, as long as your day stays productive and in sync with the team. Extra time off. Your birthday is a holiday here. Add to that 10 personal days each year, seven sick days without paperwork, and extra time to enjoy Christmas and New Year. Time to rest is part of the deal. Work that matters. Our mission is to build a digital world that is secure, accessible and inclusive for everyone. From fighting fraud to making online services easier and safer to use, your work will have a real impact on how people experience trust online. Compensation. We offer fair and transparent pay, benchmarked to the market. Truly global. We work across continents and time zones, with teammates and customers from all over the world. You will run campaigns that cross borders, cultures, and languages, and see your ideas land worldwide. Growth built in. Clear goals, open feedback and personal development plans. We support your progress with learning opportunities and by covering role-specific events, from design conferences to marketing forums. Team offsites. Sometimes just Slack is not enough. That is why we meet in person a few times a year. Trips are fully covered, so you can meet, collaborate, and recharge together. Getting you set up. We make sure you have access to the tools and hardware you need to do your work well. Friendly by design. Our logo is a dog for a reason. We keep things human, open and kind. We welcome individuality, quirks and different perspectives, because that is what makes our work smarter and more fun. The hiring stages: TA screening -> Hiring Manager Interview -> Assignment -> Final Interview. Sounds like a great opportunity for your career development? Then go ahead and apply! We are a global community of innovators, creators, and thinkers, and we believe that diversity fuels our innovation. Sumsub is proud to be an equal opportunity employer, committed to building a diverse and inclusive workforce.
