Hardware Engineer ADAS and High Speed Design
L&T EPS | 4-7 years | B.Tech / M.Tech | Onsite | Permanent
Role Overview
Own the complete design and development of ADAS hardware comprising power modules, SoC, camera, Ethernet, and DDR interfaces-from requirements and circuit design through board bring-up, debugging, and validation.
Key Responsibilities
- Own hardware development: Translate ADAS requirements into hardware architecture and drive design, development, bring-up, and validation.
- Develop circuit designs: Select components, develop schematics in Altium, and maintain the BOM for power modules, SoC, camera, Ethernet, and DDR interfaces.
- Guide PCB implementation: Define layout constraints and review placement, stack-up, routing, grounding, and decoupling for high-speed performance and EMI/EMC.
- Verify design margins: Perform WCCA, power-budget calculations, and power-sequencing checks to confirm operation across specified conditions.
- Review SI/PI results: Assess simulation findings and incorporate necessary schematic and PCB improvements.
- Bring up and debug hardware: Verify power rails, clocks, resets, and interfaces; investigate failures and implement corrective actions.
- Drive hardware validation: Develop test plans, execute functional and electrical tests, and document results against hardware requirements.
- Resolve EMI/EMC issues: Investigate test failures, implement design corrections, and verify their effectiveness through retesting.
- Support system integration: Work with software and system teams to resolve hardware-software interface and integration issues.
- Maintain design documentation: Document design calculations, reviews, test results, and revisions throughout development.
Required Skills and Expertise
- Hardware Design: Strong fundamentals in analog, digital, and mixed-signal circuits, component selection, schematic design, and board-level debugging.
- SoC & Interfaces: Hands-on design experience with SoC-based hardware, DDR memory, Ethernet, and camera interfaces, including power, clock, and reset requirements.
- Power Module Design: Experience with power supply design, power budgeting, regulator selection, power sequencing, decoupling, and power distribution.
- High-Speed PCB Design: Understanding of PCB stack-up, controlled impedance, differential routing, length matching, termination, return paths, and crosstalk mitigation.
- Altium Designer: Proficiency in schematic capture, component libraries, BOM generation, and PCB layout review.
- Worst-Case Circuit Analysis (WCCA): Ability to evaluate component tolerances, voltage and temperature variations, and circuit operating margins.
- Signal & Power Integrity (SI/PI): Understanding of simulation methods and results, including reflections, crosstalk, timing margins, and power distribution network performance.
- EMI/EMC Troubleshooting: Practical experience identifying noise sources and coupling paths, implementing grounding, filtering, shielding, and layout corrections, and verifying improvements.
- Bring-Up & Validation: Experience with board power-on, interface verification, fault isolation, and root-cause analysis using oscilloscopes, multimeters, and logic analyzers.
