• Establish security requirements for RF communications, telemetry, and command systems
• Implement cryptographic key management for space and ground systems
• Secure network infrastructure, including air-gapped and classified environments
• Design secure boot chains, trusted execution environments, and hardware root of trust implementations

• Lead cross-functional security reviews involving hardware, firmware, and software teams
• Mentor engineers on systems security best practices across the full stack
• Drive security integration into Dev Sec Ops  pipelines and hardware development
• Interface with government customers on security accreditation requirements (RMF, ICD 503, NIST 800-53)

• Ensure compliance with DFARS, CMMC, ITAR, and aerospace security standards

Qualifications:

• Bachelor's degree in Computer Science, Information Security, or a related field
• 12+ years of experience in Cybersecurity with focus on systems, embedded or infrastructure security
• Experience with hardware security principles (secure boot, TPM, HSM, side-channel attacks)
• Experience securing embedded Linux, RTOS, or bare-metal systems
• Demonstrated knowledge of cryptography implementation in resource-constrained environments
• Expertise in network security, including air-gapped architectures and secure enclaves
• Active Secret clearance, or ability to obtain and maintain one
• U.S. citizenship is required, due to program requirements

These Qualifications Would Be Nice To Have:

• Master's degree in Computer Science, Information Security, or related field
• Active TS/SCI clearance

• Knowledge of satellite communication protocols and RF security
• Familiarity with DO-178C, DO-254, or similar safety-critical development standards
• Hardware reverse engineering or penetration testing experience
• Certifications:
  
  CISSP, GIAC (GPEN, GXPN), CEH, or equivalent
• Experience with FPGA security or hardware design tools (Vivavo, Quartus)

Additional Requirements:

• Sit at desk and operate computer, keyboard and office equipment for extended periods
• Use hands with dexterity to operate controls, tools and technical equipment, as needed
• Read technical documents, drawings, and computer screens requiring close and distance vision
• Move between buildings, labs, and work areas, as needed
• Work in office and technical environments with occasional exposure to noise, dust and fumes in production areas.

The expected salary range for the position is displayed in accordance with the Colorado Equal Pay for Equal Work Act. Final agreed upon compensation is based upon individual qualifications and experience. Base salary is only one part of Rocket Lab's compensation package for this role. You may be eligible for company stock, or cash incentives, and can purchase discounted stock through Rocket Lab's Employee Stock Purchase Program.

Employee benefits also include medical, dental, and vision insurance coverage; 401(k) retirement plan options; paid vacation, holidays, and sick leave; paid parental leave; and other discounts and perks.

Base Pay Range (CO Only): $150,000 - $200,000 USD

What To Expect:

We're on a mission to unlock the potential of space to improve life on Earth, but that's not an easy task. It takes hard work, determination, relentless innovation, teamwork, grit, and an unwavering commitment to achieving what others often deem impossible. Our people out-think, out-work, and out-pace. We pride ourselves on having each other's backs, checking our egos at the door, and rolling up our sleeves on all tasks big and small.

We thrive under pressure, work to tight deadlines, and our focus is always on how we can deliver, rather than dwelling on the challenges that stand in the way.
