Job description

The Role 

As a Principal Integration & Test Engineer, you will help hone K2's approach to subscale and full vehicle production, qualification testing, and operation. Your work will span most technical disciplines at the company and will require building consensus from disparate stakeholders. You will be asked to help mentors others while serving as a critical driver for on-time delivery and mitigating mission risk. Our goal is to develop a fully autonomous constellation and that starts on the ground. You'll be the driver of constellation-level control to realize this goal.  

Responsibilities 

  • Develop company-wide standards for vehicle test (manual and automated) used to confirm spacecraft hardware and software flightworthiness
  • Operate spacecraft (interpret telemetry, send commands) during system tests at the factory, test facilities, launch sites, and during pre-launch operations 
  • Act as a test conductor (and sometimes POC) for environmental test campaigns
  • Mentor more junior members of the team
  • Interface with customers to scope testing performed on their payloads, based on expected functions and failure modes of interest
  • Manage relationships with launch vehicle providers, including contractual deliverables such as interface control documents and environmental test plan justifications 
  • Lead high-visibility (proto)qualification campaigns for development and flight hardware 
  • Assess risks associated with different integration and test approaches, justify test reductions and optimize vehicle build/test flows for at-rate production 

Qualifications 

  • Bachelor's degree in electrical, aerospace, mechanical, computer, or other relevant engineering discipline 
  • 8+ years of experience in an integration/test/automation engineering role  
  • 5+ years of experience testing and troubleshooting spacecraft and their related components and systems, including subsystem checkouts and system acceptance testing 
  • Experience with environmental testing, such as thermal vacuum or random vibration 
  • Experience working in a clean room and with ESD-sensitive equipment 
  • Hands-on experience using electrical test equipment (PSU, Oscilloscope, DMM, etc.) 
  • Hands-on experience with HITL/HWIL or Flatsat software verification testbeds 
  • Excellent conflict resolution and negotiation skills 

Nice to Have 

  • Proficient in Python and/or Rust 
  • Experience with Linux systems 
  • Experience managing contractual interfaces (e.g. customer, launch vehicle) 

Compensation and Benefits 

  • Base salary range for this role is $175,000 - $200,000 + equity in the company 
  • Salary will be based on several factors including, but not limited to: knowledge and skills, education, and experience level 
  • Comprehensive benefits package including paid time off, medical/dental/vision coverage, life insurance, paid parental leave, and many other perks
