Systems Engineer

deci

Bel Research has an immediate opening for a Systems Engineer in Huntsville, AL.

The successful candidate will:

• Serve as a primary Systems Engineering point of contact for product capabilities within one or more agile development teams supporting Missile Defense Agency (MDA) Modeling and Simulation (M&S) efforts
• Author, maintain, and refine system‑level requirements and associated governance artifacts using Model‑Based Systems Engineering (MBSE) principles in collaboration with Product Owners and development teams
• Lead or significantly contribute to system architecture decisions, CONOPS development, interface definition, logical software structure, trade studies, technical risk evaluations, and gap analyses
• Drive detailed requirements derivation, test case construction and traceability, integration planning, verification/validation, and System‑of‑System (SoS) integration of M&S capabilities throughout the development lifecycle
• Ensure the Systems Engineering Management Plan (SEMP) and associated artifacts (traceability matrix, verification & validation plans, interface specifications, etc.) are maintained, applied, and continuously improved within agile workflows and product life cycles
• Drive adoption of agile systems engineering best practices

• Bachelor's degree in Systems Engineering, Software Engineering, Computer Science, Electrical Engineering, Physics, Mathematics, or other relevant STEM field required.
• Master's degree in a related technical discipline is a plus.

• 3-8 years of professional experience supporting Modeling and Simulation (M&S) products or related technical systems
• Hands‑on experience with scripting languages (primarily Python); familiarity or ability to quickly learn compiled languages such as C++ is a plus
• Demonstrated experience defining, deriving, and verifying system/software requirements in an M&S environment, including traceability and verification/validation activities
• Applied Model‑Based Systems Engineering (MBSE) principles and techniques across software/system life cycles (tool‑agnostic approach preferred; SysML familiarity a plus)
• Experience collaborating on logical software architecture, supporting detailed design and implementation efforts, and working in agile software development environments (iterative cycles, Scrum/Kanban or similar, clear Acceptance criteria)
• Practical understanding of natural physics simulation concepts and integration/testing of M&S products within System‑of‑System (SoS) environments
• Proven ability to produce technical reports, briefing materials, and communicate complex concepts effectively (written and oral)
• Working familiarity with lifecycle management tools such as Jira and Confluence
• Experience authoring and maintaining governance artifacts such as Use Cases, interface control documents/specifications, and executable specifications
• Prior involvement in development and production of technical Contract Data Requirements List (CDRL) deliverables for DoD programs
• Hands‑on experience with real‑time and/or non‑real‑time testing of Modeling and Simulation (M&S) products
• Familiarity with Modular Open Systems Approach (MOSA) principles and their application in defense or simulation systems
• Exposure to additional MBSE diagramming tools or techniques (beyond core requirement tools) as needed for clarification or stakeholder communication
• Willingness and ability to contribute directly to software implementation or testing tasks to support team velocity

Applicant selected must have an active security clearance or the ability to attain a Secret security clearance. Must be a U.S. Citizen.
