Backend Engineer - Java (Crypto)

• Design, build, and maintain core Java services and APIs that power custody and asset-management workflows with emphasis on correctness, availability, scalability, and performance. • Integrate internal modules and external services into a unified platform while maintaining data integrity and reliable inter-service communication. • Produce clean, well-documented, testable code and set quality standards through code reviews and engineering best practices. • Troubleshoot and resolve issues in distributed systems using observability tooling (health checks, metrics, tracing, logging) to identify and eliminate bottlenecks. • Collaborate with product managers, designers, security, and other engineering teams to translate product requirements into secure, maintainable technical designs. • Contribute to reliability and incident-response processes, including post-incident analysis and remediation.

• 4+ years of software engineering experience delivering production-grade systems in high-stakes or regulated environments. • Expert-level proficiency in Java and familiarity with the JDK internals. • Hands-on experience with microservice architectures, RESTful APIs, and messaging systems (e.g., Kafka). • Strong systems-design skills with a security-first mentality and proven experience building fault-tolerant systems that are supported in production. • Solid testing mindset — unit, integration, and end-to-end testing strategies and automation. • Clear communicator who can explain technical concepts to both technical and non-technical stakeholders across distributed teams. • A sense of ownership and willingness to drive features end-to-end.
