Performance Sr. Staff Stability & Control / Performance Engineer
Posted on 10/24/2022
Mountain View, CA, USA
Experience Level
  • The goal of the S&C and Performance group at Wisk is to perform linear and non-linear stability & control analysis, size flight control surfaces, evaluate flight characteristics, calculate performance data and assist the safety team to build the first fully autonomous all-electric aircraft that performs and operates safely in an urban air-mobility environment
  • The successful candidate has direct hands-on experience developing and testing fixed wing aircraft and/or rotorcraft, from initial concept through flight testing and certification, with the technical breadth necessary to interface with all engineering functions such as Systems & Safety Engineering, Hardware, Software, Manufacturing, Test, and Certification. In this role, the candidate must be a highly motivated, self-starting individual with a broad set of skills and never afraid of facing complex technical challenges
  • B.S. in Aerospace Engineering, or another relevant discipline
  • 8+ years of experience doing detailed S&C and/or Performance analysis on fixed wing aircraft and/or rotorcraft
  • Gained strong knowledge of performance methodologies and associated software development for performance data reduction & expansion tools
  • Developed performance data for inclusion in Aircraft Flight Manual (AFM), Flight Planning and Cruise Control Manual (FPCCM), etc
  • Developed test plans based on an understanding of the certification requirements and associated means of compliance for fixed wing aircraft and/or rotorcraft
  • Excellent understanding of key concepts and equations for performance and handling qualities analysis
  • Experienced with scripting languages and Simulation tools (e.g. Fortran, Python, MATLAB)
  • You are a highly motivated, self starting individual with a broad set of skills and never afraid of facing complex technical challenges
  • You are a solution oriented individual with a strong analytical mindset
  • You have an ability to question traditional assumptions and apply your knowledge to novel eVTOL designs and operational scenarios
  • You have strong communication skills and can easily tailor your communications to suit the audience
  • You can adapt quickly or propose changes needed to achieve early results in a timely fashion
  • You embrace challenges and take commitments and deliver results within reasonable expectations
  • You are a positive team player
  • Develop, modify, and run in-house tools, including 6DoF simulation models, to analyze aircraft static & dynamic flight characteristics and performance during take off, hover, transition, climb, cruise, descent and landing
  • Estimate critical performance parameters, such as stall speeds, best rate of climb, climb ceiling, maximum range, noise profiles and energy reserves
  • Define aerodynamic smoothness criteria and perform trade-studies to optimize the aircraft design, including wing design, tail volume, control surface sizing and sensor requirements
  • Support the GNC team to assess, verify and validate control laws and envelope protection functions to ensure safe operations and compliance with the relevant certification and design requirements
  • Plan and participate in both wind-tunnel and flight tests to analyze stability & control and performance data to support certification, including instrumentation requirements and parameter identification for simulator matching
  • Develop tools & processes for performance data reduction & expansion, and optimization of flight mission planning for safe operations of an autonomous aircraft
  • Author and review certification documents to show compliance with FAR Part 23/27 requirements
Desired Qualifications
  • M.S. in Aerospace Engineering, or another relevant discipline
  • 12+ years of aircraft performance analysis experience working on complex aerospace systems
  • Understanding of fixed-wing and/or rotorcraft aerodynamics, including familiarity with the use of RANS CFD codes and lower fidelity tools such as Xfoil & AVL
  • FAA Flight Analyst Designated Engineering Representative (DER) or previous experience working on an aircraft certification program
  • Familiarity with relevant aerospace standards and handling qualities rating systems (FAA, ASTM, NASA, MIL-STD-1797, MIL-F-8785, ADS-33, etc.)
  • Knowledge of rotorcraft performance and the theories associated with propeller and rotor-driven propulsion
  • Experience with wind tunnel, simulation and flight testing for aircraft performance and flight characteristics
  • Previous experience with the various phases of an aircraft development program, from conceptual design thru certification and in-service support
