Backend Engineer

About Echo

Echo delivers frontier-hardened software across the enterprise software supply chain.
Echo's containers, libraries, OS packages, VMs, and more are built and patched from source by agentic pipelines, and continuously vetted for supply chain threats. With us, developers and agents can build with secure-by-default software that's compatible with the tools and versions they already use.

We're looking for a Backend Engineer to join our team and take ownership of the core of our platform: the backend systems behind our artifact factory and CVE remediation, and the services and integrations our customers rely on.

What you'll do

• Own the core backend of Echo's platform: the services and AI workflows behind our artifact factory, CVE remediation, and the customer-facing product

• Drive backend architecture and technical decisions, working closely with Product and other engineers from planning through delivery

• Build integrations with the tools our customers already use, such as registries, or vulnerability scanners

• Scale our APIs and data pipelines to handle large volumes of vulnerability, package, and build data

What you bring

Required

• 5+ years of backend development experience (Node.js preferred)

• Strong background in designing and implementing microservices-based architecture

• Extensive experience with cloud environments, particularly AWS

• Hands-on experience with CI/CD pipelines, build automation, and deployment processes

• Hands-on experience with databases (SQL/NoSQL) and distributed messaging systems (e.g. Kafka, RabbitMQ)

• Proven ability to optimize performance and scalability in backend systems and services

• Excellent communication skills and proven ability to work effectively in cross-functional teams

Preferred

• Experience with workflow engines (e.g. Temporal) and analytical databases (e.g. ClickHouse)

• Familiarity with software supply chain or vulnerability data
