About the role

About You and The Role

As a Mechanical Hardware Reliability Engineer, you will be responsible for defining and delivering the Safety and Reliability attribute of our latest drone-delivery systems. You’ll combine deep knowledge of failure phenomena in electromechanical devices, hands-on experimentation, and statistical modeling to ensure Zipline’s latest drone-delivery platforms survive the most demanding environments on Earth.

Your work will span from early architecture decisions, like where to apply redundancy, fail-operational strategies, and fault tolerance through the definition of accelerated tests, coding reliability models, and verification methods. You’ll uncover risks early, provide data to risk-based decisions, and guide design teams with clear, actionable recommendations. In doing so, you’ll directly shape the long-term reliability and safety of Zipline’s autonomous aircraft and ground infrastructure.

What You'll Do

  • ◆Own the reliability strategy for mission-critical mechanical subsystems or entire systems, applying Design-for-Reliability (DfR) and Physics-of-Failure (PoF) principles.
  • ◆Translate system reliability targets into design-level requirements, verification plans, and objective pass/fail criteria.
  • ◆Lead DFMEA efforts with cross-functional teams to identify early risks and drive mitigation.
  • ◆Develop Accelerated Life Testing (ALT) and environmental test campaigns to validate long-term hardware performance.
  • ◆Author test plans and procedures with clear, data-driven pass/fail criteria.
  • ◆Lead failure analysis and structured root cause investigations, from component to system-level.
  • ◆Lead failure analysis and structured root-cause investigations, translating findings into design, manufacturing, or operational actions.
  • ◆Sign off on test verification results and assess hardware readiness for flight from a reliability standpoint.
  • ◆Define operational life limits and service intervals using a combination of test data, field returns, and statistical models.
  • ◆Advocate cross-functionally for reliability: maintain an appropriately high reliability bar based on risk assessment and stage of program
  • ◆Improve Zipline’s reliability methods, tools, standards, and decision-making processes as the company scales.

What You'll Bring

  • •B.S. or M.S. in Mechanical Engineering, Materials Engineering, or a related technical discipline.
  • •Strong mechanical engineering fundamentals and the ability to reason from first principles about hardware behavior and failure.
  • •Hands-on experience developing and validating safety-critical electromechanical systems through delivery to customers.
  • •Experience applying reliability methods such as DFMEA, accelerated-life testing, environmental testing, failure analysis, or life modeling.
  • •Strong technical communication skills, including the ability to:
  • •explain complex technical issues clearly;
  • •synthesize ambiguous information into a coherent problem statement;
  • •write concise, decision-oriented technical documentation; and
  • •drive cross-functional alignment on reliability trade-offs and technical decisions around design, supply-chain, quality, manufacturing, finance, and operations.
  • •Demonstrated ownership and practical problem-solving ability, including driving technically complex issues through resolution.
  • •Ability to learn quickly, independently develop new technical depth, and adapt as program needs evolve.
