From the original posting
K2 is building the largest and highest-power satellites ever flown, unlocking performance levels previously out of reach across every orbit. Backed by over $1 billion in total funding from leading investors including Altimeter Capital, ICONIQ, Kleiner Perkins, Lightspeed Venture Partners, Redpoint Ventures, and T. Rowe Price — and with over $1 billion in signed contracts across commercial and US government customers, we're mass-producing the highest-power satellite platforms ever built for missions from LEO to deep space.
The Role
You will be responsible for designing some of the highest power systems ever flown in space. You will be able to develop a broad range of power electronics devices ranging from power switching to power conversion components capable of operating in the harshest space environments. In your first 6 months you will prototype your first high power devices and execute environmental and performance testing to refine your designs. In your first year you will qualify your hardware for flight and begin designing even more capable devices for future generations of spacecraft. In your first two years you will have flown your power devices in space and developed novel designs across all power domains.
Responsibilities
- Develop power electronics for large spacecraft with power systems ranging from 20kW to 100kW capability
- Serve as Responsible Engineer for flight hardware from conception through flight
- Qualify your designs through environmental testing including vibration, shock, thermal, and thermal vacuum testing
- Work with partners/customers to define interfaces between the power system and various spacecraft loads
- Develop models to analyze and verify power system performance
Qualifications
- Bachelor’s degree in electrical engineering
- 5+ years of professional design experience with power electronics (research and extracurricular academic projects qualify)
Nice to Have
- Proficient with circuit simulation tools such as LTspice
- Experience with environmental testing for space electronics such as thermal testing, vibration testing, TVAC testing, shock testing, radiation testing, and EMI/EMC testing
- Experience with high performance kW scale isolated power converter design
- Experience with load switch design and power path protection schemes
- Experience with power stage component selection for use in radiation environments
- Knowledge of filter design for stability, noise rejection, and surviving threat signals
- Experience programming in C/C++, Python, or Matlab
Compensation and Benefits:
- Base salary range for this role is $160,000 - $210,000 + 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
If you don’t meet 100% of the preferred skills and experience, we encourage you to still apply! Building a spacecraft unlike any other requires a team unlike any other and non-traditional career twists and turns are encouraged!
