Specialty Systems Engineer

Are you ready for your next career challenge? Leidos Defense Sector provides a diverse portfolio of systems, solutions, and services covering land, sea, air, space, and cyberspace for customers worldwide. Solutions for Defense include enterprise and mission IT, large-scale intelligence systems, command and control, geospatial and data analytics, cybersecurity, logistics, training, and intelligence analysis and operations support. Our team is solving the world's toughest security challenges for customers with "can't fail" missions. Leidos' Defense Space Business Area is seeking a Specialty Systems Engineer to join a collaborative Systems Engineering Integration and Test team developing a variety of sensor payloads for space. This is an exciting opportunity to leverage your expertise across risk, reliability/availability, radiation, and cybersecurity disciplines — combined with strong MBSE modeling skills — while contributing to our national defense mission.

Overview: We are seeking an experienced Specialty Systems Engineer with strength in risk analysis and one or more specialty disciplines (reliability, availability/maintainability, radiation effects analysis, or cybersecurity) and hands-on proficiency with Model-Based Systems Engineering (MBSE) in Cameo Systems Modeler. The person fulfilling this role must be a skilled communicator who collaborates closely with subject matter experts (SMEs), builds relationships across disciplines, and translates specialty analysis into actionable system models and requirements.

Risk Management Conduct comprehensive risk assessments to identify, measure, and monitor potential threats to company assets, profitability, and operational integrity. Develop and enforce risk management policies, frameworks, and internal controls aligned with industry standards. Design and implement actionable risk mitigation plans, collaborating cross-functionally with department leaders to reduce exposures. Prepare regular risk reports for executive leadership and ensure ongoing compliance with regulatory requirements and governance standards and run risk management review boards. Specialty Engineering (Risk / Reliability / Availability / Radiation / Cybersecurity) Conduct or facilitate reliability and availability/maintainability analyses (e.g., FMEA, FTA, RBD, RAM predictions) to identify, measure, and mitigate threats to system performance and mission success. Support the performance of radiation effects analysis for space systems (e.g., total ionizing dose, single-event effects, radiation hardness assurance) through interaction with subject matter exports Support cybersecurity risk assessments (e.g., threat modeling, vulnerability analysis, RMF/ATO activities) to ensure systems meet mission assurance and security requirements. Monitor and report specialty performance metrics to program and executive leadership, including risk exposure, reliability/availability figures of merit, radiation tolerance margins, and cybersecurity posture, and recommend corrective actions. Collaborate cross-functionally with program management, design engineering, and logistics to integrate specialty findings — risk, reliability/availability, radiation, or cybersecurity drivers — into program baselines, design trade-offs, and compliance with applicable standards (e.g., MIL-STD-785, MIL-HDBK-338, NIST RMF). MBSE / Cameo Modeling Develop and maintain structural, behavioral, and parametric system models using SysML in Cameo Systems Modeler, leveraging Teamwork Cloud for collaborative, version-controlled model management. Translate specialty analyses (risk, reliability, availability, radiation, or cybersecurity data) into model-based artifacts, establishing bi-directional traceability from stakeholder needs through requirements, architecture, and verification and validation (V&V). Map system-of-system architectures and define physical, logical, and software interfaces, integrating specialty
