Submarine Senior Systems​/Platform Engineer San Diego ca

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. This Full Time role based in San Diego, CA, US requires an experienced leader responsible for driving requirements, architecture, and interface governance while coordinating cross‐discipline teams and serving as the primary liaison with government stakeholders and shipboard integration teams.

Key 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 point of contact 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, Magic Draw).
• 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).

Required Qualifications

• 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).

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 Dev Sec Ops/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.

Benefits & Perks

• 100% employer‑paid health, dental, and vision coverage
• 401(k) with 6% match
• Industry‑leading PTO package and continuing education reimbursement
• Hybrid onsite/remote work environment, long‑term stability with a prime contract, and opportunities for rapid career growth
