Description
Systems Security Engineer
Location: Phoenix, AZ
Company Stage of Funding: Early-Stage / Defense Technology Startup
Office Type: Onsite, Full-Time
Salary: Competitive (based on experience)
Security Clearance: Ability to obtain U.S. Secret clearance required
1. Company Description
We’re representing a defense technology company building autonomous swarm systems designed for demanding national security environments. Their fleet of autonomous unmanned ground vehicles operates across embedded, edge, and cloud environments, combining GPU-accelerated computing, secure communications, and distributed fleet management infrastructure.
The company is scaling rapidly and building its security posture from first principles. Security is not an afterthought — it is core to the product. This role will sit at the center of ensuring resilience, compliance, and mission readiness across embedded platforms, vehicle-to-cloud communications, and cloud-hosted services.
2. What You Will Do
As a Systems Security Engineer, you will own and execute the company’s end-to-end security strategy across embedded systems, cloud infrastructure, and compliance programs. This is a hands-on individual contributor role with full ownership of technical security architecture and operational execution.
You will:
-
Design and implement secure system architectures across embedded platforms, GPU-accelerated systems, and cloud-hosted services.
-
Architect and enforce cloud security controls (IAM, network segmentation, encryption, multi-tenancy, and zero-trust patterns).
-
Secure embedded systems including secure boot, trusted execution environments, firmware security, key management, and hardware security modules.
-
Protect heterogeneous CPU/GPU systems (e.g., NVIDIA Jetson-class platforms).
-
Secure vehicle-to-cloud communications and distributed system protocols.
-
Conduct threat modeling, vulnerability analysis, and system-level security assessments.
-
Implement continuous monitoring, vulnerability tracking, and remediation processes.
-
Lead compliance and accreditation activities, including preparation of documentation for Authority to Operate (ATO).
-
Align systems with federal cybersecurity frameworks such as NIST, FISMA, and CMMC.
-
Brief security architectures and compliance status to government stakeholders and leadership.
-
Coordinate security incident response activities.
-
Establish internal security policies and scalable monitoring processes as the company grows.
This role requires building systems and processes from scratch in a fast-paced startup environment where execution and ownership are critical.
3. Ideal Background
The ideal candidate is a technically deep security engineer who thrives in complex cyber-physical systems and defense environments.
-
6+ years of experience in systems security engineering or cybersecurity.
-
Bachelor’s degree in Computer Science, Computer Engineering, Electrical Engineering, Cybersecurity, or related field.
-
Experience securing complex embedded systems, including firmware, hardware security modules, and key management.
-
Experience designing security architectures for cloud platforms (AWS, Azure, or GCP).
-
Strong network security fundamentals (firewalls, VPNs, TLS/mTLS, secure communications, zero-trust models).
-
Experience securing distributed systems and vehicle-to-cloud communication pipelines.
-
Experience conducting vulnerability analysis and system-level security assessments.
-
Experience supporting compliance and accreditation processes, including ATO preparation.
-
Working knowledge of federal cybersecurity frameworks (NIST, FISMA, CMMC, etc.).
-
Ability to obtain and maintain a U.S. Secret security clearance.
-
Strong communication skills and ability to operate as the primary security owner.
-
Comfortable working onsite in Phoenix, AZ.
4. Preferred
-
Experience serving as the primary security engineer at an early-stage hardware, robotics, or defense company.
-
Background in autonomous systems, robotics, aerospace, or cyber-physical platforms.
-
Active U.S. TS/SCI clearance.
-
Strong programming experience in C++ and Python.
-
Experience securing GPU environments (CUDA, TensorRT).
-
Experience with penetration testing or red teaming for embedded systems.
-
Experience with container security, infrastructure-as-code scanning, secrets management, and SIEM/SOAR tooling.
-
Familiarity with ROS or robotics software stacks.
-
Experience with supply chain risk management and system-level testing processes.
5. Compensation and Benefits
-
Compensation: Competitive salary based on experience.
-
Work Model: Full-time, onsite in Phoenix, AZ.
-
Clearance: Ability to obtain and maintain U.S. Secret clearance required (active clearance not required at hire).
-
Impact: Direct ownership of the security posture of autonomous systems deployed in national security environments.
-
Growth: Opportunity to architect and scale security from the ground up in a high-impact defense startup.
Mission Alignment:
This role is ideal for engineers motivated by contributing to the defense of the United States and its allies.
Equal Opportunity:
The company is committed to equal employment opportunity and complies with all applicable federal, state, and local employment laws.
