Joby Overview

Located in Northern California, the Joby Aviation team has been steadily working toward our goal of providing safe, affordable, fully electric air transportation that is accessible to everyone. Imagine an air taxi that takes off vertically, then quietly and quickly carries you over the congestion below, giving you back that time you’d otherwise spend sitting in traffic. Technology has advanced to the point where designing and operating an all-electric aircraft is completely viable. Our team has been discreetly designing and flight testing this vehicle and is looking for talented individuals to see it through certification and high rate production.


The HIRF and Lightning Certification Engineer will be the focal for design, qualification, and certification activities related to HIRF and Lightning compliance across all of engineering, including grounding, static, EMI, EMC, etc. This role will serve as the internal Subject Matter Expert as well as the primary external point of contact with regulatory agencies and industry standards groups for aircraft, system, and equipment level HIRF and Lightning considerations. The most important traits at Joby are a positive attitude towards the project, strong work ethic, and being able to self-manage and learn new skills. Forward thinking and the ability to adapt quickly to a fast-paced environment are a must. It is preferred that this individual be an FAA DER or candidate. 


This position will be responsible for:

  • Determining and interpreting the certification basis and establishing the compliance strategy – including means and methods of compliance

  • Establish relevant design development and certification plans that will support Type Certification
  • Convey and document requirements in a way that clearly breaks down the regulations and guidance material
  • Develop engineering specifications for airframe bonding, HIRF protection, and lightning protection 
  • Review designs, develop solutions, and ensure compliance with the airworthiness standards
  • Planning out test campaigns, overseeing test article fabrication, and witnessing tests in order to demonstrate that applicable designs show compliance with airworthiness standards
  • Interfacing with certification authorities as required (FAA, EASA, etc.)


This position requires candidates to have or be:

  • Expert-level understanding of design standards and verification methods for HIRF and lightning protection of aircraft, static dissipation, and electromagnetic interference and compatibility
  • Expert-level understanding of RTCA/DO-160 Environmental Conditions and Test Procedures for Airborne Equipment – specifically sections related to induced signals, radio frequencies, lightning, and electrostatic discharge
  • Previous experience with HIRF and lightning aspects of aircraft certification
  • Previous FAA certification experience with avionics and electrical systems and/or equipment (TSO, TC/ATC, STC, etc.)
  • Basic knowledge of 2X.1309 analyses and processes, including Advisory Circular 23.1309-1E, SAE ARP4761, and SAE ARP4754A
  • The ability to question traditional assumptions in the application of regulations, guidance material, and engineering specifications
  • The ability to read, review, and create technical schematics, engineering specifications, and engineering drawings
  • At least 10 years of relevant aviation or aerospace industry experience
  • A Bachelor of Science in an applicable engineering discipline
  • Proficient in English
