Job Title: Firmware Software Engineer III
Duration: 12 Months 
Location: Redmond,  WA
 
Summary
We are looking for a Firmware Engineer to join our wearables research team, whose mission is to design, build, and test prototype systems for future wearables experiences. We are specifically looking for a candidate with a broad set of experiences, including deep knowledge of embedded software development, the ability to quickly solve problems, work in new technology areas, and drive ambiguous concepts into prototypes.
 
Responsibilities

• Develop and debug firmware for a wearable device that includes multiple sensors and cameras, application processor running Android and co-processor(s)
• Develop firmware on micro-controllers or BSPs for embedded linux, leverage peripherals, manage power consumption, support boot loaders, and schedule real-time tasks (RTOS)
• disciplines
• Develop test applications to interface with a variety of peripherals
• Test the developed firmware with the hardware
• Document designs and performance analysis

 
REQUIRED Qualifications

• B.S. degree in Computer Science, Electrical Engineering, or equivalent experience
• 5+ years of SW/FW experience.
• 3+ years experience with embedded architectures such as ARM Cortex, or processors running AOSP/Embedded Linux, such as QC Snapdragon Wearables or AR2G1.
• 3+ years experience with high and low speed peripherals and buses, and developing and modifying drivers for them.
• Ability to describe their previous use of logic analyzers or protocol decoders to debug/troubleshoot.
• Ability to autonomously identify, report, and solve problems with minimal direction.
• Ability to work in a dynamic, high-paced environment where job duties may change frequently

 
PREFERRED Qualifications

• Experience with AOSP/Embedded Linux driver development and associated frameworks, like kconfig, device tree, Android, Yocto, Build root.
• Familiarity with HW-in-the-loop testing, CI/CD, build system configuration / scripting.

 
Top 3 Must-Have Skills:
1. Embedded Software Development ? 5+ years of software/firmware (SW/FW) experience ? Deep knowledge of embedded architectures (ARM Cortex, AOSP/Embedded Linux, QC Snapdragon Wearables, AR2G1) ? Proven ability to develop and modify drivers for high/low speed peripherals and buses 
2. Firmware Debugging & Hardware Interface ? 3+ years experience using logic analyzers or protocol decoders for debugging and troubleshooting firmware ? Skilled in developing test applications to interface with a variety of hardware peripherals 
3. Microcontroller & Embedded Linux Development ? 3+ years experience developing firmware on microcontrollers or BSPs for embedded Linux (QC Snapdragon Wearables or AR2G1) ? Ability to manage power consumption, support boot loaders, and schedule real-time tasks (RTOS).
 
Preferred Skills:

• Experience with AOSP/Embedded Linux driver development and associated frameworks, like kconfig, device tree, Android, Yocto, Build root ? Familiarity with HW-in-the-loop testing, CI/CD, build system configuration / scripting.

 
Degrees/Certifications:

• B.S. degree in Computer Science, Electrical Engineering, or equivalent experience.

 
Day-to-Day Responsibilities:

• Work with lead and peers to understand your program tasks, attend team stand ups and deliver features per program milestones. 

 
About the Team:

• Part of a ten person FW team developing experiences for wearables research.

 
How is success defined?
1. Perform day-to-day responsibilities. 2. Work autonomously, navigate ambiguity, and collaborate cross-functionally.
 
Unique challenges?

• The prototyping scale of work means that we make decisions on the balance of speed and rigor. Additionally, we have to adapt our plans as we discover what works, or doesn’t work, while building prototypes.

 
What makes this role interesting?

• Our team tackles the risky HW/FW tech maturation to make possible lightweight, high powered wearable experiences for customers, with the goal of transferring technology to our product partners to scale.

 
Value Added/Experience Gained:

• You will collaborate with world-class experts in a dynamic environment that fosters creativity, impact, and continuous learning, driving breakthroughs that shape the future of Meta's products and services.

 
Interview Process:

• 3 ROUNDS  ROUND 1 - SCREEN - Proctored 10 min pre-screen question (no interviewer help.)   \
• If pass, then: ROUND 2 - CODING - 60 min coding screen with two engineers (with option to end at 30 min mark if signal isn’t strong.)  
• If pass, then (optional):  ROUND 3 (Optional) - BEHAVIORAL - 45 min behavioral with CWAM
