Job Title :

System integration Engineer(Diagnostics)

Location:

Foster City, CA Job Description:

Key Responsibilities Diagnostic Algorithm Design & Implementation:

Architect and implement real-time diagnostic monitors in modern C++, including signal-level plausibility checks, degradation detection, and fault isolation logic. Perform software unit testing, HIL testing, and automated regression tests to validate diagnostic algorithms prior to final implementation

Diagnostic Requirement Engineering:

Author formal diagnostic monitor requirements (detection thresholds, debounce strategies, fault response actions) traceable to system-level or component level failure modes; verify requirements against fleet and bench data.

Data-Driven Analysis & Validation:

Leverage large-scale fleet data in Databricks to characterize faults, tune detection thresholds, validate algorithm performance (detection rate, false-positive rate), and drive continuous improvement.

Fault Troubleshooting & Root Cause Analysis:

Lead investigation of field-reported faults using telemetry, logged data, and replay tools; identify root causes spanning hardware, firmware, calibration, and environmental factors.

Documentation & Knowledge Transfer:

Produce clear technical specifications, design documents, and service procedures that enable Fleet Operations technicians to diagnose and resolve faults efficiently.

Continuous Improvement:

Monitor fleet-wide diagnostic KPIs; propose and implement algorithm refinements, new monitors, and process improvements.

Qualifications Experience:

.6 8 years of professional experience in diagnostics, embedded controls, or vehicle systems engineering within the automotive, autonomous vehicle, aerospace, or robotics industry.

Required Skills Vehicle Diagnostics Expertise:

Working knowledge of diagnostic standards and protocols (UDS / ISO 14229, DTC management, OBD-II / SAE J1979) and communication buses (CAN, LIN, Automotive Ethernet).

Data Analysis:

Proficiency with Python for data analysis and visualization; experience working with large-scale telemetry datasets (Databricks, or equivalent). C++

Proficiency:

Strong, demonstrable C++ development skills in production or safety-critical environments;

Control & Estimation Theory:

Hands-on experience designing and implementing control algorithms, state estimators, or model-based diagnostic observers.

Problem Solving:

Proven ability to systematically decompose complex, multi-domain problems and drive them to root cause under ambiguity.

Communication:

Excellent written and verbal communication skills; able to present technical analyses and recommendations to both engineering peers and non-technical stakeholders. Preferred Skills Experience with implementing prognostics or vehicle health monitoring Experience with HIL/SIL testing frameworks for diagnostic validation.
