Safety & Reliability Engineer

About the role

This position focuses on ensuring the safety and reliability of hydrogen-electric powertrains for aviation. The work involves conducting various system safety analyses, such as FHA, PSSA, and FTA, in accordance with ARP4761A standards. A key aspect of the role is to develop and execute reliability predictions and analytical models to meet specific RAM targets and certification objectives, contributing directly to the airworthiness of new aerospace technologies.

The engineer will define Built-In-Test (BIT) coverage and system health monitoring requirements, integrating observability into system architectures. This includes generating clear, verifiable safety and reliability requirements that align with program goals and airworthiness objectives. Success in this role means effectively defining and recommending reliability test strategies, and analyzing in-service data to drive product improvements and inform maintenance strategies.

The role also requires developing and communicating robust safety arguments for complex systems, particularly fuel cell technologies, to both internal and external stakeholders. The individual will support certification activities, which includes engaging with regulatory bodies, attending familiarization meetings, and participating in technical reviews to ensure compliance with aerospace certification frameworks like CS-23 and CS-E.

The listed salary range for this position is between $60,000 and $90,000 USD.

Skills that matter here

• ARP4761A: This standard guides the system safety analyses, including FHA, PSSA, SSA, FTA, FMECA, CCA, PRA, and ZSA, that the engineer will perform.
• Reliability analyses: The role requires performing various reliability analyses, such as prediction, FMECA, FTA, and PoF, to support RAM targets and certification.
• MIL‑HDBK‑217F: Working knowledge of this and other reliability standards like FIDES and Telcordia is needed for developing reliability predictions.
• BIT strategies: The engineer will define Built-In-Test strategies and system health monitoring architectures to embed observability into system designs.
• ARP4754: Familiarity with this standard for systems development processes and safety-critical certification frameworks is beneficial.
• Aerospace certification: An understanding of aerospace certification processes, such as CS-23 and CS-E, is necessary to support regulatory engagement and technical reviews.

Who this role suits
