Submarine Senior Systems/Platform Engineer Full TimeSan Diego, CA, US30+ days agoRequisition ID: 1035ApplySalary Range:$125,000.00 To $150,000.00 Annually Position: Submarine Senior Systems/Platform Engineer Location: San Diego, CA (Hybrid considered) Clearance Requirement: Secret (TS/SCI preferred) Employment Type: Full-time Position Overview XSITE LLC is seeking a Lead Systems Engineer / Platform Architect to set technical direction and own the architectural baseline for submarine platform capabilities at the hardware–software boundary. Youll operate as a technical authority and chief integrator—driving requirements, architecture, and interface governance; coordinating cross-discipline teams; and serving as the primary liaison with government stakeholders and shipboard integration teams. This role emphasizes leadership, decision-making, and stakeholder alignment over hands-on implementation. What Youll Do • Own the technical baseline: Define and evolve CONOPS, system architecture, and interface control; maintain traceability from mission needs to verification evidence. • Lead integration by influence: Orchestrate HW/SW integration across labs, SIL/HIL, and shipboard environments; set entry/exit criteria and readiness gates. • Governance & decision-making: Chair or support design reviews (SRR/SDR/PDR/CDR), TIMs, CCBs, and technical risk boards; run trades and document decisions. • Requirements leadership: Establish verification strategies and allocation; ensure requirements and ICDs remain synchronized with delivered capability. • Stakeholder liaison: Serve as the primary technical POC with Navy customers, primes, and suppliers; align roadmaps, constraints, and test/sealift schedules. • Quality & reliability oversight: Direct teams building diagnostics, regression suites, and observability; ensure platform reliability and performance targets are met. • Digital/MBSE leadership: Guide SysML modeling, model governance, and alignment with requirements/data artifacts (e.g., DOORS/Jama Cameo/MagicDraw). • Cyber & networks coordination: Oversee integration for tactical networks and platform cyber posture (RMF/ATO considerations, DISA STIG/SRG alignment). • Plan the lifecycle: Shape the SEMP, V&V/TEMP approach, integration plans, and sustainment strategies; measure progress with meaningful technical metrics. Note: This is a leadership/architect role. Hands-on coding or bench work is not the primary focus (though you should be able to read logs, designs, and code when needed). Travel: Occasional lab/shipyard/test-range events as program needs dictate. Required Qualifications • Bachelors in Engineering, Computer Science, Information Systems, Applied Science, Physics, or related field. • 10+ years in systems/platform engineering with 5+ years leading multi-disciplinary teams or major subsystems. • Demonstrated ownership of system architecture, ICDs, and requirements for complex, safety- or mission-critical systems. • Experience leading integration and V&V across embedded devices, onboard servers, and tactical networks. • Proficiency with requirements management (e.g., DOORS/Jama) and MBSE/SysML practices and governance. • Strong communication and stakeholder management skills; proven record presenting to government customers and leadership. • U.S. Citizenship; Secret clearance (TS/SCI preferred). Preferred Qualifications • Undersea/maritime domain experience (submarine C5I, combat systems, edge compute). • Knowledge of open architecture standards (e.g., SOSA, CMOSS, OMS/UCI) and deterministic comms (MIL-STD-1553, CAN, RS-422/485). • Familiarity with DevSecOps/CI/CD at the platform level and enterprise/tactical networking (routing, VLANs, QoS). • Cybersecurity/RMF/ATO awareness (DISA STIGs/SRGs) and supply/supplier integration oversight. • Exposure to HIL/SIL, digital twins/simulation, and reliability engineering. Success Looks Like • A stable, scalable architectural baseline with clear, enforced interfaces and decision records. • Predictable integration cycles and readiness reviews that surface risks early and retire them on schedule. • Measurable improvements in platform reliability, performance, and deployment cadence to the Fleet. • High stakeholder confidence through clear communication, artifacts, and on-time technical milestones.
