Embedded Security Engineer, Saronic

• Bachelor’s or Master’s degree in Computer Science,
• Electrical/Computer Engineering, Software Engineering, or a related field
• Proficiency in Rust and/or C/C++ developing software for embedded Linux
• Strong understanding of cryptographic primitives and protocols (keys, certificates, signatures, TLS/mTLS), and experience integrating them into systems
• Experience with secure/verified boot, OTA/update safety, and firmware/bootloader workflows
• Familiarity with VPN overlays and constrained-network security patterns
• Comfortable with Linux security fundamentals (users/permissions, capabilities, sandboxing) and systemd-based service management
• Excellent problem-solving skills and ability to collaborate effectively in na fast-paced, cross-functional environment
• Strong written and verbal communication skills
• This role requires the ability to obtain and maintain a security clearance
• Prolonged periods of sitting at a desk and working on a computer
• Occasional standing and walking within the office
• Manual dexterity to operate a computer keyboard, mouse, and other office equipment
• Visual acuity to read screens, documents, and reports
• Occasional reaching, bending, or stooping to access file drawers, cabinets, or office supplies
• Lifting and carrying items up to 20 pounds occasionally (e.g., office supplies, packages)

Desirable

• Design, develop, and maintain security features for embedded Linux systems (systemd-managed services, Rust/C/C++) used for navigation, control, and communications
• Own per-vessel identity and mutual authentication for boat↔cloud and boat↔boat links; implement certificate/key rotation and revocation workflows
• Implement signed/verified update mechanisms with rollback protection; collaborate with manufacturing on secure boot enablement and key provisioning
• Integrate and operate hardware-backed key storage (e.g., TPM/secure elements) and sealed secrets for on-vessel services
• Harden network paths over constrained links: TLS/mTLS, VPN overlay policies, and least-privilege service access
• Reduce attack surface in embedded services (capabilities, seccomp/AppArmor where appropriate, safe process execution, input validation)
• Build tamper-evident, structured logging and diagnostics suitable for ship→shore analysis and incident response
• Perform threat modeling, code reviews, and security testing (static/dynamic analysis, fuzzing, negative testing)
• Troubleshoot and debug complex security issues in fielded systems; author runbooks and safe-rollback procedures
• Document designs, processes, and verification results for compliance and knowledge sharing; contribute to secure coding guidelines
• Stay current on emerging security technologies and best practices relevant to embedded Linux and autonomous systems
