Elliptic is developing AI-powered tools that enable compliance teams to investigate crypto transactions more quickly and with greater confidence.Elliptic'scopilotalready reduces compliance review times by 50%.

Our Automation Forge team is at the heart of this effort, designing the backend systems and AI integrations that power Elliptic's copilot, an AI-driven assistant created to streamline and enhance digital asset risk management.

We are seeking a backend-focused Software Engineer to help design and build the APIs, workflows, and services that enable this innovation. This is an exciting opportunity to experiment and drive innovation in a dynamic space.

The impact you will have:

As aSoftware Engineer on theAutomation Forgeteam, you will help design and deliver scalable, reliable services that power Elliptic’s copilot and other AI‑driven features.

You’ll partner with product managers, web engineers and your engineering lead to turn complex blockchain data into intelligent, user‑friendly experiences that help compliance teams trace fund flows, uncover deeper patterns, and respond to risk with greater speed and confidence.

Working collaboratively across disciplines, you’ll contribute to impactful features and continuously improve quality, reliability, and innovation across the platform. Through this work, you’ll play an essential role in advancing Elliptic’s mission to make crypto markets safer, more transparent, and more efficient.

What you will do:

• Design, build, and maintain backend services and event-driven systems using TypeScript and Node.js.

• Develop APIs and workflows that integrate AI and LLM frameworks to power Elliptic's copilot and other intelligent features.

• Design, optimise, and query data models across relational and NoSQL databases.

• Collaborate with cross-functional teams to deliver features from concept through to production.

• Take part in technical design reviews, planning sessions, and code reviews to continuously improve system quality.

• Contribute to infrastructure and observability practices alongside the team — you won't own this alone, but you'll be expected to care about how your services run in production.

What You'll Bring

• 3–6 years of backend engineering experience with TypeScript and Node.js like NestJS or Express.

• Proven ability to design, build, and maintain robust, well-documented APIs and integrate with external systems.

• Hands-on experience with AWS services (e.g., Lambda, ECS, S3) in production environments.

• Proficiency in SQL databases (PostgreSQL or similar) and familiarity with NoSQL solutions.

• A methodical, analytical approach to system design, architecture, and technical trade-offs.

• Excellent communication and collaboration skills, working effectively with engineering, product, and design teams.

Nice to Have

• Familiarity with LangChain or other LLM/AI frameworks. If you haven't used these yet but are eager to learn, that counts too.

• Hands-on experience with Terraform, Kubernetes, or infrastructure-as-code tooling.

• Experience with observability platforms like Datadog (metrics, tracing, alerting).

• Familiarity with distributed or event-driven architectures (SNS, SQS, etc.).

• Interest in cryptocurrency, blockchain technology, or compliance though we're happy to bring you up to speed.

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.
