Submarine Senior Systems/Platform Engineer

XSITE LLC • San Diego, CA

80d

About The Position

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. You’ll 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.

Requirements

• Bachelor’s 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).

Nice To Haves

• 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.

Responsibilities

• 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.

Benefits

• 100% employer-paid health, dental, and vision coverage
• 401(k) with 6% match
• Industry-leading PTO package
• Continuing education reimbursement
• Hybrid onsite/remote work environment
