Senior / Staff Robotics Security Software Engineer

Security Software EngineerSaronic Technologies is a leader in revolutionizing autonomy at sea, dedicated to developing state-of-the-art solutions that enhance maritime operations through autonomous and intelligent platforms.Job OverviewWe are seeking a Security Software Engineer to design, implement, and harden the security controls across Saronic's autonomous surface vessel fleet. This role spans three layers: edge compute on the vessels themselves, the networks that enable vessels to communicate with each other and with the cloud, and the cloud orchestration layer that manages the fleet at scale. You will work hands-on in a Rust-first ecosystem, on NixOS-based embedded Linux platforms, building security features that ship into production and operate reliably in real-world maritime environments.ResponsibilitiesDesign and implement secure boot, hardware roots of trust, trusted execution environments, rollback protection, and secure update and over-the-air delivery pipelines for vessel computeImplement per-vessel identity and mutual authentication for vessel-to-vessel and vessel-to-cloud links, implement certificates, key rotation, and revocation workflows, and protect message integrity against replay and spoofing across intermittent, bandwidth-constrained, and contested links (satellite, cellular, and mesh radio)Build and maintain cryptographic services bridging vessel and cloud infrastructure, and harden identity and access controls, secrets and key management, and containerized workloadsSecure NixOS configurations using Nix's declarative and reproducible model, drive vulnerability management across third-party crates and dependencies, and embed security into CI/CD pipelines from build through deploymentPartner with autonomy, platform security, manufacturing, and field teams to embed security requirements from the ground up, and collaborate with the enterprise and application security teams on threat modeling, risk assessment, and incident response to ensure implemented controls align with overarching policy and standardsContribute to architecture and interface design documents and participate in code and design reviews to maintain high security and coding standardsBuild reusable security tools, libraries, and instrumentation across the codebase to solve hard security problems using automation and AI-assisted approachesQualificationsBachelor's or Master's degree in Computer Science, Software Engineering, or a related field.3+ years of experience in security software engineering, preferably in autonomy, robotics, or embedded systems.Proficiency in programming languages such as C/C++ or Rust and hands-on experience securing embedded Linux systemsSolid understanding of cryptographic primitives and protocols (keys, certificates, signatures, TLS, and mutual TLS) and experience integrating them into real systemsExperience with hardware security modules, secure boot, and system-level software spanning kernel and bootloaderFamiliarity with networking protocols and IPC/message-passing frameworksKnowledge of DoD standards and regulations related to security software development is advantageousPrior work on autonomous systems is a plusExperience with real-time systems is a plusExcellent problem-solving skills and ability to work in a fast-paced startup environmentStrong communication skills and the ability to collaborate effectively with cross-functional teamsPhysical DemandsProlonged 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).BenefitsComprehensive health insurance plans covering a range of servicesSaronic pays 100% of the premium for employees and 80% for dependentsCoverage for routine dental check-ups, orthodontics, and vision careSaronic pays 99% of the premium for employees and 80% for dependentsGenerous PTO and HolidaysPaid maternity and paternity leave to support new parentsIndustry-standard salaries with opportunities for performance-based bonuses401(k) planEquity options to give employees a stake in the company's successBasic life insurance and short- and long-term disability coverageFree lunch benefit and unlimited free drinks and snacks in the office
