Role
Who you are
- We're looking for a hands-on, detail-oriented engineer who is passionate about identifying failure risks early in the design cycle, driving cross-functional collaboration, and delivering hardware that performs reliably in the harshest real-world environments
- Bachelor’s degree in Electrical Engineering, Mechanical Engineering, Materials Science, or a related field (Master’s preferred)
- 5+ years of hands-on reliability engineering experience, preferably in electromechanical systems or sensors
- Proven track record in testing and validating hardware components for long-term field performance
- Strong understanding of physics of failure and reliability engineering principles, particularly for electronic, optical, or mechanical systems
- Experience with environmental and mechanical stress testing, including test design, execution, and result interpretation
- Familiarity with reliability analysis tools and techniques: FMEA, Weibull analysis, SPC, HALT/HASS, and accelerated life testing
- Proficiency in scripting or automation using tools such as Python, MATLAB, or LabVIEW
- Experience working with reliability test equipment such as environmental chambers, vibration tables, thermocouples, strain gauges, and data acquisition systems
- Strong communication and collaboration skills to work effectively with design, systems, manufacturing, and test teams
What the job involves
- As we continue to develop and deploy cutting-edge autonomous technologies, we are seeking a Senior Reliability Engineer (REL) to lead efforts in ensuring the long-term performance, durability, and robustness of critical hardware systems
- This role is a key part of our Hardware Reliability team, with a focus on driving reliability strategy, testing, and validation across a broad range of electromechanical components, including sensors
- Lead reliability engineering efforts across hardware programs, ensuring components and systems meet demanding performance, environmental, and durability requirements
- Apply Design for Reliability (DfR) principles throughout the product lifecycle, from concept through production, to proactively mitigate failure risks
- Develop and execute comprehensive test strategies to uncover failure modes, validate off-the-shelf and custom hardware, and model expected field performance
- Translate FMEA and reliability risk analyses into targeted test plans with clearly defined objectives, acceleration factors, and pass/fail criteria
- Plan and run Design of Experiments (DOE) to isolate root causes and address key reliability concerns
- Design and optimize test fixtures and setups to evaluate hardware under electrical, thermal, mechanical, and environmental stresses (shock, vibration, thermal cycling, etc.)
- Drive and support failure analysis investigations, collaborating closely with design, manufacturing, and component teams to identify root causes and implement corrective actions
- Leverage data analytics tools (e.g., Python, JMP, MATLAB) to automate testing workflows, perform reliability modeling (e.g., Weibull, Monte Carlo), and extract actionable insights from test data
- Champion continuous improvement in reliability processes and tools across hardware engineering teams
Our take
The last decade has seen a major uptick in the number of startups and companies dedicated to supporting consumers to build good health habits, typically around food and fitness. That enthusiasm is now quite rightly being extended to how we sleep.
Eight Sleep makes “smart” mattresses and mattress covers (for regular mattresses) that use machine learning and other artificial intelligence-based algorithms to improve your sleep both by changing temperature and monitoring other physical parameters to provide an overall picture of your health.
The company is focused on two levers for growth. First, building out more technology through additional products and acquisitions, exemplified by the introduction of Span Health’s fitness-tracking app. Secondly, international expansion in Europe, where it has got off to an impressive start in the UK.
