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 a Full Stack Engineer 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.
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 will play a key role in shaping how compliance teams track and prevent financial crime.
- You'll work across the full stack, building and improving 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 turn complex data into simple, useful product features and help drive the platform's speed, precision, and usability forward.
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 end-to-end.
- Develop and optimize data visualizations for complex transaction flows and network graphs, making the complex feel simple.
- Improve platform speed and precision by optimizing queries, improving frontend responsiveness, and shipping 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 that raise the quality bar for the team.
- Contribute to technical design discussions, raising trade-offs and risks early.
What you will achieve in the first 6 months:
- Ship multiple production features across frontend and backend that improve the investigator experience.
- Take ownership of medium-sized pieces of work from ambiguous problem statements through to shipped outcomes.
- 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 quality 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 independently break down ambiguous product problems into well-scoped technical tasks.
- Show good instincts for trade-offs between technical quality and shipping speed.
- 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, not just another job.
- Focus on what really matters by delivering meaningful results that serve both users and the business.
Our ideal candidate has:
- 3-4+ years of professional software engineering experience.
- Strong experience with modern JavaScript and TypeScript across backend (Node.js/NestJS) and frontend (React/Redux) development.
- Solid understanding of building and maintaining scalable UI applications and APIs, with the ability to make informed decisions about technology choices.
- Comfortable working with databases and writing SQL queries, and partnering with data engineers on integration points.
- Some experience or comfort with data visualization, particularly libraries or tools for rendering complex network graphs and transaction flows.
- Actively uses AI coding assistants (Copilot, Cursor, Claude, etc.) as part of their daily workflow, can critically evaluate AI-generated code, and understands when AI tools are useful and when they're not.
Bonus Points for:
- Experience with cloud technologies such as AWS Serverless, API Gateway, Kubernetes, and Terraform.
- Familiarity with monitoring tools like DataDog and general observability best practices.
- Interest or experience in cryptocurrency and blockchain technology.
- Experience with graph databases or visualization libraries for rendering complex network data.
Job Benefits
- Hybrid working and the option to work from almost anywhere for up to 90 days per year.
- £500 Remote working budget to set up your home office space.
- $1,000 Learning & Development budget to use on anything (agreed with your manager) that contributes to your growth and development.
