Our team is solving the world's toughest security challenges for customers with "can't fail" missions.

Leidos' Defense Space Business Area is seeking aSpecialty 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.

Position 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.

Key Responsibilities:

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 engineering inputs (e.g., reliability block diagrams, risk registers, radiation margin data, security control mappings) directly into the digital model.
• Execute trade study analysis focusing on -illity related requirement and risk posture

Required Skills:

• Experience as risk manager and running risk review boards
• Superior organization and leadership skills and attention to detail
• High level of commitment to quality work product and organizational ethics, integrity, and compliance
• Ability to work effectively in a fast-paced, team environment
• Strong interpersonal skills and the ability to effectively communicate, both written and verbally
• Demonstrated decision making and problem-solving skills
• Detail-oriented with the ability to multi-task and meet deadlines with minimal supervision

Basic Qualifications:

• BS degree and 4+ years of relevant experience, or Masters with 2+ years of relevant experience
• Must be a US Citizen
• Must have an active Secret Clearance
• Experience modeling in Cameo Systems Modeler (or equivalent) using SysML, and experience using Teamwork Cloud
• Experience in risk management and one or more specialty disciplines: reliability engineering, availability/maintainability analysis, radiation effects analysis, or cybersecurity
• Experience deriving requirements for complex electrical, mechanical, optical, and software systems
• Familiarity with technical data management, report writing and support tasks
• Demonstrated ability in change management, process improvement, project planning, and stakeholder management
• Ability to demonstrate a commitment to personal and corporate excellence, ethical behavior and integrity

Preferred Qualifications:

• Experience with space systems, specifically space payloads
• Object Management Group (OMG) Certified System Modeler Professional (OCSMP) certification
• INCOSE Systems Engineering Professional (SEP) certification (ASEP or CSEP)
• Certification or training relevant to specialty area (e.g., ASQ CRE for reliability, Security+/CISSP for cybersecurity)
