About this role

Join Elliptic as a Senior Backend Engineer to tackle complex problems in blockchain risk management. Work on high-throughput backend services and contribute to a values-led company focused on employee growth.

Description

Do you want to be part of the future of value transfer? Are you excited about solving problems that have never been solved before? Are you looking for a values led company, which cares about the growth of its employees? Elliptic's Real-time Risk team builds the engine that powers how our customers screen, monitor, and act on blockchain risk. We own the data pipelines, scoring infrastructure, and continuous monitoring systems that keep compliance teams ahead of financial crime, in real time, at enterprise scale.

Responsibilities
  • Design and build robust, high-throughput backend services supporting real-time risk scoring, screening, and continuous monitoring workflows.
  • Work closely with data engineering teammates to deliver personalised intelligence to our customers, enabling unique, customer-specific views of the blockchain.
  • Contribute to world-class sanctions reporting infrastructure that compliance teams and regulators depend on.
  • Help scale the system to support Elliptic's growing enterprise customer base, identifying and resolving performance and reliability bottlenecks.
  • Take ownership of technically complex areas, driving architecture and implementation decisions with sound trade-off reasoning.
  • Review code, raise the technical quality of the team, and mentor engineers where appropriate.
  • Collaborate with product, data, and engineering stakeholders to translate compliance requirements into well-designed, maintainable systems.
Requirements
  • 5+ years of professional software engineering experience building and operating production backend systems.
  • Strong TypeScript/Node.js experience, with the ability to write clean, well-tested, production-ready code.
  • Proven experience working with complex event-driven, streaming, or queue-backed architectures (e.g. Kinesis, Kafka, SQS, or similar) in a production environment.
  • Solid understanding of distributed systems trade-offs: consistency, availability, latency, and failure modes.
  • Experience working with NoSQL and caching technologies, with comfort reasoning about data access patterns and performance.
  • A track record of contributing to technically complex codebases, and the ability to communicate architectural thinking clearly.
  • AI fluency: you actively use AI tools to accelerate your work, and can demonstrate how you apply them effectively in engineering contexts.
Conditions & 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.
  • Holidays: 25 days of annual leave + bank holidays.
  • An extra day for your birthday.
  • Enhanced parental leave: we provide eligible employees, regardless of gender or whether they become a parent by birth or adoption, 16 weeks fully-paid leave.
  • Private Health Insurance - we use Vitality!
  • Full access to Spill Mental Health Support.
  • Life Assurance: 4 times your salary to your beneficiaries.
  • £100 cryptocurrency for you!
  • Cycle to Work Scheme.
