Elliptic has helped trace and disrupt over $21.8 billion in illicit crypto laundered across blockchains, from sanctioned nation states to organized crime networks hiding funds through token swaps and unregulated exchanges. It’s how compliance and investigations teams fight back, tracking and screening transactions with 99% market coverage.
The Customer Platform is what makes that possible at enterprise scale. We build a secure customer environment and strong platform foundations that help teams ship confidently and keep Elliptic enterprise-ready.
We’re looking for a Full‑Stack Software Engineer to help us design and build the customer-facing experiences and platform services that power authentication, governance, user management, and operational tooling.
The impact you will have
As a Full‑Stack Software Engineer on the Customer Platform team, you will help deliver secure, scalable features that shape the “front door” experience for Elliptic customers and enable product teams to build and ship safely.
You’ll work across frontend and backend, partnering with designer, and other engineers to turn enterprise requirements into reliable, user-friendly experiences.
Through this work, you’ll play an important role in helping Elliptic be the definitive choice for enterprises and financial institutions, by strengthening the operational infrastructure and development platform that the business depends on.
What you will do
- Build and maintain full‑stack features across web UI and APIs, from design through to production.
- Work with a broad variety of platforms, standards and paradigms, such as Auth0, OAuth2, SAML, SCIM, and event-driven architectures
- Deliver secure customer-facing capabilities such as login/signup flows, user management, governance, and enterprise features.
- Design and evolve backend services and APIs for shared platform components to support Elliptic’s growth (e.g., authn/authz, API gateways, and related supporting services)
- Collaborate with other product teams to make it easy and safe to integrate with Customer Platform capabilities.
- Take part in technical design reviews, planning, and code reviews, raising quality and clarity.
What you’ll bring
- 3–6 years’ software experience building production services in TypeScript/Node.js (or equivalent) and modern web apps (React or similar).
- Strong fundamentals in web engineering: HTTP, APIs, authentication/authorisation concepts, and secure coding practices.
- Cloud experience in a production environment (AWS or equivalent).
- Database proficiency: comfortable with SQL (Postgres or similar).
- A structured approach to problem-solving: you can explain trade-offs and make pragmatic decisions.
- Strong collaboration and communication: you work effectively across engineering, product, design, and operations.
Nice to have
- Experience with Node.js frameworks such as NestJS or Express.
- Familiarity with identity and enterprise auth standards (SAML, SCIM, OAuth/OIDC).
- Hands-on experience with Terraform, Kubernetes, or infrastructure-as-code tooling.
- Experience with observability platforms (metrics, tracing, alerting).
- Exposure to API gateways (e.g., Kong/Envoy Gateway) and multi-tenant SaaS patterns.
Don’t meet every requirement?
If this role excites you but your experience doesn’t perfectly match every bullet point, we’d still love to hear from you. We value curiosity, willingness to learn, and diverse perspectives just as much as specific tool experience.
Ensuring that people of all backgrounds, identities, and experiences feel welcome at Elliptic is an ongoing priority for us. We believe diverse thinking enables us to solve problems in new ways — benefiting both our team and our customers.
