Job description

The Role 

As K2's Crypto Engineer, you will own the architecture and design of our Type-1 cryptographic integrations across the spacecraft and ground segment. You will carry these designs cradle-to-grave - from concept and trade studies, through implementation and integration, to NSA certification and accreditation, and into on-orbit operations. You'll define how K2's satellites protect command, telemetry, and mission data; partner with NSA, government customers, and certification authorities; and ensure our COMSEC architecture meets the bar for national-security missions while fitting the pace and scale of a high-volume satellite production line. This is a foundational role: you'll set the cryptographic standards the rest of the program builds against. 

Responsibilities 

  • Own the end-to-end architecture and design of Type-1 cryptographic integrations across the spacecraft, payload, and ground segment 
  • Lead crypto designs from concept and trade studies through implementation, integration, certification, and on-orbit operations 
  • Define COMSEC architecture for command, telemetry, and mission data protection, including encryption, key management, and key loading approaches 
  • Serve as K2's primary technical interface to NSA, certification authorities, and government customers on cryptographic certification and accreditation 
  • Drive the certification and accreditation effort, developing the artifacts, test evidence, and documentation required to achieve and maintain approval to operate 
  • Partner with flight software, avionics, RF, ground, and security teams to integrate cryptographic functions into the broader system architecture 
  • Support COMSEC handling, key management planning, and operational procedures for on-orbit fleet operations 
  • Identify and mitigate cryptographic and supply-chain risks across design and production 
  • Establish reusable cryptographic standards, interfaces, and processes that scale across K2's satellite production line 

Qualifications 

  • Bachelor's degree or higher in electrical engineering, computer engineering, computer science, or a related discipline 
  • 5+ years of engineering experience with cryptographic systems, COMSEC, or secure communications 
  • Direct experience with NSA Type-1 cryptographic equipment, integration, and certification processes 
  • Working knowledge of key management, key loading, and COMSEC handling requirements 
  • Experience taking a hardware or system design through certification and accreditation to operational use 
  • Strong systems-level thinking with the ability to reason from first principles across hardware, software, and RF boundaries 
  • Ability to work in a fast-paced, autonomously driven, and demanding startup atmosphere with competing priorities and aggressive schedules 

Nice to Have 

  • Experience with spacecraft, satellite, or other space-system cryptographic integrations 
  • Familiarity with cryptographic modernization initiatives and current NSA-approved algorithms and equipment 
  • Experience with RMF/ATO, JSIG, or other accreditation frameworks 
  • Background in RF, link design, or secure command and telemetry systems 
  • Experience supporting on-orbit or fielded operations 

Additional Requirements 

  • Ability to travel up to 25% of the time 
  • Active Top Secret or Top Secret SCI clearance required; ability to obtain and maintain access to additional programs as needed 
  • Ability to work irregular business hours to support critical project timelines or operations 
  • This role requires access to information controlled under ITAR/EAR; applicants must be a U.S. Person as defined by applicable regulations 

Compensation and Benefits 

  • Base salary range for this role is $160,000 - $245,000 + 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
