Backend Engineer - Java

What you'll do

• 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.

What you'll bring

• 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.

Nice to have

• Experience with digital assets, blockchain protocols, custody solutions, or traditional financial services.
• Familiarity with application/network security best practices and secure coding patterns.
• Experience using AI tooling to accelerate development workflows.
• Experience with cloud providers, especially Google Cloud Platform (GCP).
• Front-end experience with React (for cross-functional collaboration).
