Avionics System Engineering

Avionics Systems Engineer
Los Angeles, CA
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 rise of heavy-lift launch vehicles is shifting the industry from an era of mass constraint to one of mass abundance, and we believe this new era demands a fundamentally different class of spacecraft. Engineered to survive the harshest radiation environments and to fully capitalize on today's and tomorrow's massive rockets, K2 satellites deliver unmatched capability at constellation scale and across multiple orbits.
With multiple launches in 2027 and plans to scale to 100 satellites a year, we're Building Bigger — helping develop the solar system and build toward a Kardashev Type II (K2) civilization. If you are a motivated individual who thrives in a fast-paced environment and you're excited about contributing to the success of a high-growth Series D-funded company, we'd love for you to apply.
The Role
You will be responsible for system design, analysis, testing and integration of avionics on some of the largest, most powerful, rapidly designed and manufactured satellites. You will have the unique opportunity to collaborate with a cross functional team of engineers to make impactful architecture trades, design new spacecraft hardware, and manage the overall avionics system implementation. You will be the Responsible Engineer for Avionics interfacing, harnessing, instrumentation, RF components, and GNC actuators. You will help establish production test requirements and support vehicle avionics integration to enable high-rate production and constellation launch cadence. In your first two years, you will have qualified hardware for flight, completed avionics integration on the satellite bus, and flown your first spacecraft.
Responsibilities

Serve as Responsible Engineer for Avionics system design, performance, and hardware across the computing, power system, instrumentation, RF components, GNC sensors, and harnessing on the satellite bus
Collaborate closely within the cross functional Engineering teams to capture requirements, lead design trades, and integrate the design into the spacecraft systems
Create and update technical documentation including system diagrams, schematics, interface control documents, procedures, test/anomaly reports
Execute Avionics component and system testing on flight hardware through development acceptance, qualification, and integration testing
Support spacecraft integration testing, production issue dispositions, troubleshooting failures, and managing overall spacecraft risk
Design, develop and build Avionics production infrastructure
Write modular, reusable test, analysis, and automation software in Python and Rust
Effectively manage and communicate project plan, milestones, and schedule execution
Qualifications

• Bachelor's degree in aerospace, mechanical, or electrical engineering or any equivalent combination of education and experience
• 2+ years of experience in the documentation, development, testing, and integration of space-grade avionics systems
• Ability to work in a fast-paced and high velocity start-up atmosphere
• Creative problem solver that can assess risk and make collaborative design and development decisions

Hands-on experience with environmental testing for space electronics and harnessing such as thermal, thermal vacuum, vibration, shock, radiation, and EMI/EMC testing per SMC-S-016
Competence with electrical test equipment (multimeters, oscilloscopes, network analyzers, etc.)
Strong presentation experience in highly technical design forums and reviews (Preliminary Design Reviews, Critical Design Reviews, Flight Readiness Reviews, etc.)
Proficient with NX or similar CAD software including electrical harness routing
Expertise in PCB schematic capture and board layout, ideally using Altium or similar software
Experience with Linux, Bash, C++, MODBUS
Experience with vehicle level testing including writing test procedures, creating robust and efficient test sequencing, and analytical data review to evaluate hardware health
Compensation and Benefits:

Base salary range for this role is $100,000 - $150,000 + 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!
If you need a reasonable accommodation as part of your application for employment or interviews with us, please let us know.
Export Compliance
As defined in the ITAR, "U.S. Persons" include U.S. citizens, lawful permanent residents (i.e., Green Card holders), and certain protected individuals (e.g., refugees/asylees, American Samoans). Please consult with a knowledgeable advisor if you are unsure whether you are a "U.S. Person."
The person hired for this role will have access to information and items controlled by U.S. export control regulations, including the export control regulations outlined in the International Traffic in Arms Regulation (ITAR). The person hired for this role must therefore either be a "U.S. person" as defined by 22 C.F.R. § 120.15 or otherwise eligible for a federally issued export control license.
