Job Title: Electrical Engineer
Location: Sunnyvale, CA - Onsite
Employment Type: Full-Time with L&T Technology Services (LTTS).
Summary:
We are seeking a mid- to senior-level Hardware Engineer to support bring-up, validation, and debugging of new sensor modules for Meta’s wearable hardware platforms. This role is highly hands-on and lab-focused, working at the intersection of hardware, firmware, and system integration. The ideal candidate is comfortable powering up early hardware, issuing firmware commands, and debugging complex system-level issues.
Job Responsibilities:
- Perform hardware bring-up of new wearable sensor modules from first power-on through functional validation
- Debug system issues across sensors, power, interfaces, and firmware
- Use firmware / low-level commands (UART, I²C, SPI, shell, or vendor tools) to configure, test, and debug hardware
- Validate sensor performance, functionality, and reliability under different operating conditions
- Execute and refine test plans, validation procedures, and debug checklists
- Collaborate closely with firmware, system, and mechanical teams to resolve issues quickly
- Work with schematic, layout, and datasheet reviews to identify potential design risks
- Document findings, root causes, and recommendations clearly for cross-functional teams
- Support rapid iteration cycles typical of early-stage wearable development
- Direct technicians, engineering designers or other technical support personnel as needed.
Skills:
- Good EE fundamentals in power and analog domain.
- Solid hands-on experience in lab equipment, such as oscillating scope, differential probes.
- Software Debugging is must
- Ability to drive projects with high ambiguity, multiple paths, and fuzzy future to clarity.
- Experience in consumer electronics and working with vendors/contract manufactures is a plus.
- Understanding of battery, thermal, and system integration is a plus.
- Experience in developing automated tests and validation is a plus.
Education/Experience:
- Bachelor's degree in engineering required.
- Direct experience with hardware bring-up of complex systems or modules
- Strong familiarity with sensor technologies (IMUs, optical, bio-sensing, environmental, etc.)
- Comfortable using firmware or diagnostic commands for hardware control and debug
- Proficient with lab equipment: oscilloscopes, logic analyzers, DMMs, power supplies
- Experience debugging I²C, SPI, UART and related low-speed interfaces
What Success Looks Like
- Able to independently bring up new sensor hardware with minimal documentation
- Quickly isolates issues across HW/FW boundaries
- Communicates findings clearly and drives issues to closure
- Thrives in fast-paced, ambiguous development environments
- Trusted by cross-functional partners as a hands-on bring-up and debug expert
