Job Summary

We are seeking a Senior Software Engineer to take technical ownership of embedded software development for advanced undersea acoustics systems.

• Collaborate with the Project Manager to plan sprints, define milestones, and track execution.
• Design and implement secure software interfaces for integration with external systems and third-party platforms.
• Contribute to containerized deployments and overall system design using Kubernetes in secure environments.
• Apply cybersecurity principles, NetBoot approach, SBOM standards, performance monitoring and fault location techniques.
• Support system-level observability and integration with upper-tier logging frameworks (e.g., Fluentd).
