Senior Software Engineer, Distributed Networks

Job description

Job responsibilities

• Design and implement new features for the Distributed Service Bus, including gossip protocols, OSPF-style link-state routing, and flow control mechanisms
• Build and extend the gRPC proxy layer that enables existing services to communicate transparently over the DSB mesh
• Debug complex distributed networking issues spanning tactical radios, UDP/TCP transports, and mesh routing — from packet captures on deployed assets to cloud infrastructure
• Collaborate with product teams across business lines to deploy DSB onto new hardware platforms and support migrations from legacy communication buses
• Design and implement protocol-level optimizations for bandwidth-constrained RF links, including compression, prefix routing, and priority-based QoS scheduling
• Write RFCs and technical design documents for new protocol features and API surfaces
• Build deterministic simulation harnesses that allow the same production code to run in fully reproducible test environments
• Improve observability through Prometheus metrics, Grafana dashboards, and CLI tooling (dsbtool) for live mesh inspection and debugging

Job requirements

• 5+ years of professional software engineering experience
• Proficiency in a systems programming language (Rust, C, C++, or Go)
• Strong understanding of networking fundamentals: TCP/UDP, socket programming, MTU, multicast, TLS/mTLS
• Experience building or maintaining distributed systems (message buses, RPC frameworks, consensus protocols, or similar)
• Familiarity with asynchronous programming models (async/await, event loops, futures)
• Comfort working with Protocol Buffers and/or gRPC
• Ability to read packet captures and use network debugging tools (tcpdump, Wireshark, etc.)
• Must be eligible to obtain and maintain a U.S. Secret security clearance
