The Principal Systems Engineer, Telematics ECU leads system-level execution and integration for connected vehicle platforms, driving system requirements and supporting end-to-end architecture decisions across hardware, SoC/modem, RF, software, and vehicle domains.

In addition, this role leads system integration, bring‑up, certification readiness, and validation to ensure secure, reliable connectivity. It partners with brands and suppliers, collaborates across hardware, software, and test teams, and offers expert technical guidance through all development phases, including board bring‑up and performance assessments while mentoring domain specialists.

• Lead system requirements gathering and traceability for telematics features, connectivity, diagnostics, and compliance.
• Assist in architecture trade-offs, performance/power estimations, RF capacity planning, and coverage/reliability targets; validate against vehicle constraints.
• Contribute to building and maintaining performance models to guide design choices; drive cross‑functional reviews and support domain signoffs with domain owners.

• Partner with hardware/RF leads to define system-level hardware and RF requirements and constraints (cellular/GNSS, eSIM, Wi‑Fi/Bluetooth, power, antenna/RF chains) and ensure they flow to silicon, RF, and PCB partners.
• Co‑review schematic/PCB progress, RF performance criteria, EVT/DVT/PVT builds, and thermal/EMC/ESD/reliability status; surface and track risks jointly with hardware/RF owners.
• Assist with coordination of lab bring‑up and RF debug plans; ensure defects are logged, owned, and resolved by the right domain experts; track antenna performance and coexistence mitigation with the hardware/RF teams.

• Lead ECU integration activities into vehicle networks (CAN/CAN FD, Ethernet, LIN as applicable) in partnership with network owners.
• Define and execute system and RF integration tests across bench, HIL, RF chambers, and in‑vehicle with cross‑domain peers; triage issues across hardware, firmware, modem stack, and applications with clear ownership and hand‑offs.
• Coordinate supplier and carrier deliverables with clear requirements, acceptance criteria, and documentation; flag risks early with supplier/carrier leads.

• Partner with SoC/modem, BSP, and middleware leads on SoC/modem selection, boot chain (UEFI/U‑Boot, secure boot), BSP, middleware, and driver integration; co‑evaluate performance/power trade‑offs.
• Support alignment of data, voice, V2X, and cloud feature roadmaps with backend and mobile teams; jointly ensure diagnostics, logging, security, and OTA readiness via system‑level plans.
• Ensure carrier and certification requirements are embedded into design and validation in partnership with modem and RF SMEs.

• Thoughtful Problem Solver & Communicator: Thinks analytically, critically & creatively and communicates with clarity, direction & purpose.
• Attentive Listener: Listens actively while withholding judgment and advice. Clarifies intentions & motivations to anticipate and address potential conflicts & avoid misunderstanding.
• Drives Diversity: Acts from a deep‑rooted belief that we build better teams & products when we empower & learn from the broadest spectrum of humanity.
• Leads with Integrity: …
