Full Stack Engineer

Do you want to build a product that investigators use to track real financial crime across blockchains? Are you excited about turning complex graph data into something intuitive and fast? Do you want your code to directly help catch bad actors? Elliptic is looking for Full Stack Engineers to join our growing Investigations team. This is a chance to work at the intersection of technology and financial crime prevention, building tools that compliance teams worldwide rely on to trace fund flows, uncover illicit activity, and protect the global financial system. We’re hiring at multiple levels. Your responsibilities, scope of ownership, and compensation will be based on the level you join at and your experience. We’ll determine the level during the interview process so you don’t need to work out where you fit before applying. You'll join a collaborative team of web and data engineers, working closely with the product team to ship features that make investigators faster and more effective. The work is technically interesting and has real impact. The team cares about quality, gives you space to do your best work, and offers real ownership across the stack. The impact you will have: As a Full Stack Engineer on the Investigations team, you'll play a part in shaping how compliance teams track and prevent financial crime. You'll work across the full stack, contributing to investigative workflows that help users trace fund flows, visualize complex transaction networks, and uncover patterns in blockchain data. Working closely with product and data engineers, you'll help turn complex data into simple, useful product features and contribute to the platform's speed, precision, and usability. What you will do - Build and improve investigative workflows that empower compliance teams to track fund flows across blockchains - Work across the full stack (React/Redux frontend, Node.js/NestJS backend, data layers) to ship product features - Contribute to data visualizations for complex transaction flows and network graphs, making the complex feel simple - Help improve platform speed and precision by working on queries, frontend responsiveness, and features that make investigators faster - Collaborate closely with product, data engineers, and cross-functional teams to deliver meaningful value - Write clean, well-tested code and participate in code reviews - Contribute to technical discussions, raising trade-offs and risks where you see them What you will achieve in the first 6 months: - Ship production features across frontend and backend that improve the investigator experience - Take ownership of work that matches your level from well-defined tickets to open-ended problem statements that need you to shape the approach. - Improve production readiness across the platform through better observability, resilience, and error handling - Build strong working relationships with data engineers, web engineers, product, and DevOps - Contribute to the team's delivery rhythm and help raise engineering standards through reviews and consistent patterns You will be a great fit here if you - Care about writing clean, reliable code and enjoy working across backend, frontend, and data systems to build great products - Can break down product problems into well-scoped technical tasks, with the level of independence appropriate to your experience - Demonstrate good judgment (or a clear trajectory toward it) in balancing technical quality with shipping pace knowing when to invest in robustness and when “good enough” is the right call. - Communicate clearly with non-engineers (product, stakeholders) about technical decisions and progress - Are curious about the domain and genuinely find blockchain data and financial crime prevention interesting - Focus on what really matters by delivering meaningful results that serve both users and the business Our ideal candidate has: - 2-4+ years of professional software engineering experience - Strong experience with modern JavaScript
