Hardware Reliability Engineer - Watch System Reliability

Apple • Cupertino, CA

9h • Onsite

About The Position

At Apple, we don’t just follow industry standards—we push beyond them. We value creative problem-solving, dynamic thinking, and the ability to quickly adapt to new technical challenges. If you’re excited about tackling tough problems and shaping the future of amazing products, we’d love to have you on board! In this role, you’ll collaborate with diverse hardware teams to ensure our products are not only durable and reliable, but also built to exceed expectations. From early concepts to field returns, you’ll lead cross-functional teams, design innovative reliability tests, and drive continuous product improvements. Come join our team!

As a System Reliability Engineer, you will define and defend product durability from early architecture through mass production. Rather than reacting to failures late in the cycle, you will characterize the fundamental balance between real-world life stress and product strength—developing targeted accelerated test methodologies, isolating failure mechanisms early, and converting empirical data into actionable design risk assessments. Your work directly steers cross-functional design decisions to ensure our products deliver an uncompromised customer experience over their full operating life.

Requirements

• B.S. in Mechanical Engineering, Materials Science, Electrical Engineering, Applied Physics, or a related discipline.
• 7+ years of hands-on industry experience in hardware reliability engineering, product validation, or failure analysis.
• Deep, practical background in physical failure analysis techniques (e.g., Optical Microscopy, X-ray/CT, SEM/EDS, cross-sectioning).
• Proven track record of methodically driving complex mechanical or electrical failures to fundamental root causes.
• Proven history of developing custom reliability test suites from first principles.
• Authoring detailed engineering test specs.
• Bringing up automated fixtures under tight NPI schedules.
• Demonstrated ability to construct concise, high-signal technical presentations (Keynote/PPT).
• Communicate complex technical trade-offs with conviction across multi-disciplinary engineering and executive teams.
• Willingness and ability to travel internationally up to 10% to support factory builds, audit vendor labs, and oversee critical test bring-up.

Nice To Haves

• M.S. or Ph.D. in Materials Science, Mechanical Engineering, Electrical Engineering, Applied Physics, or an equivalent field.
• Mastery of reliability statistics and modeling tools (JMP, Python, or R), including Weibull analysis, accelerated test modeling (Arrhenius, Peck, Coffin-Manson), sample size determination, and degradation analysis.
• Experience taking complex, compact electromechanical systems or wearable devices from early concept through mass production ramp.
• Specialized knowledge in one or more core degradation modes: adhesive/seal integrity, drop/impact shock dynamics, environmental ingress, corrosion kinetics, or material fatigue.
• Proven ability to navigate high ambiguity, challenge assumptions with rigorous data, and mentor junior engineers on analytical rigor and decision-making.

Responsibilities

• Define and defend product durability from early architecture through mass production.
• Characterize the fundamental balance between real-world life stress and product strength.
