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. 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. * 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., We extend equity participation to every full-time team member, recognizing and rewarding your direct contributions to our success. This includes periodic equity refreshments based on performance, ensuring that as Eight Sleep grows and succeeds, so do you - perfectly aligning your achievements with the broader triumphs of the company. Pay grows rapidly as you accumulate experience with Eight Sleep and translate it into concrete impact. ## Related Videos - [Leveraging Large Language Models for Legacy Code Translation: Challenges and Solutions](https://www.wearedevelopers.com/videos/1157-leveraging-large-language-models-for-legacy-code-translation-challenges-and-solutions) - [Dirty Tests And How To Clean Them](https://www.wearedevelopers.com/videos/515-dirty-tests-and-how-to-clean-them) - [Leading with Reliability: Applying SRE Principles to Build Stronger Engineering Organizations](https://www.wearedevelopers.com/videos/100185-leading-with-reliability-applying-sre-principles-to-build-stronger-engineering-organizations) - [Building a hypercar from scratch](https://www.wearedevelopers.com/videos/607-building-a-hypercar-from-scratch) - [More efficient software for more efficient microchips](https://www.wearedevelopers.com/videos/1164-more-efficient-software-for-more-efficient-microchips) - [Stop Guessing, Start Measuring: Evaluating RAG Systems with Synthetic Test Data](https://www.wearedevelopers.com/videos/1982-stop-guessing-start-measuring-evaluating-rag-systems-with-synthetic-test-data) ## Related Articles - [What is Software Engineering?](https://www.wearedevelopers.com/magazine/289-what-is-software-engineering) - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk) - [Top Characteristics of a Software Engineer](https://www.wearedevelopers.com/magazine/166-top-characteristics-of-a-software-engineer) - [Highest Paying Tech Companies for Developers](https://www.wearedevelopers.com/magazine/220-highest-paying-tech-companies-for-developers) - [Software Engineer Career: Things You Should Know](https://www.wearedevelopers.com/magazine/143-software-engineer-career-things-you-should-know) - [Best Countries for Software Engineers](https://www.wearedevelopers.com/magazine/267-best-countries-for-software-engineers)
