Job description

Position Description

deciBel Research has an immediate opening for a Senior Systems Integration Engineer in Huntsville, AL. This role supports advanced Modeling & Simulation (M&S) programs that enable critical defense missions and integrates software components, digital models, hardware interfaces, and test capabilities into cohesive system workflows.

The position is highly collaborative, working alongside the PMO and other functional engineering disciplines while maintaining a dedicated focus on integration execution, verification planning, test coordination, documentation quality, and technical readiness. Strong engineering fundamentals and rapid learning capability are essential. Prior M&S experience is helpful but not required.

Responsibilities

Systems Integration and Technical Execution

• Lead integration of software components, digital models, hardware interfaces, and test systems for M&S environments.
• Translate system and subsystem requirements into actionable integration tasks, verification steps, and coordinated test activities.
• Develop and maintain integration test plans, procedures, verification matrices, and supporting engineering documentation.
• Support interface definition (ICDs), configuration updates, and controlled baseline management activities.
• Conduct integration events, system checkouts, test readiness reviews, and multi‑discipline technical coordination with software, M&S, test, and systems engineering teams.
• Assist with benchmark comparisons of integrated M&S toolchains to validate performance, accuracy, and expected model behavior.
• Identify integration risks early, elevate cross‑functional impacts, and coordinate mitigation plans.
• Contribute to model integration workflows such as CAD simplification, mesh preparation, data ingestion, and fidelity evaluation.
• Collaborate with program management and other internal stakeholders to communicate system status, integration progress, and technical risks.
• Mentor junior engineers on integration methodology, documentation standards, test discipline, and verification best practices.

Proposal & Technical Writing Support

• Develop or contribute to technical volume content for proposals, including system integration strategies, test concepts, and verification approaches.
• Author technical responses for RFIs, engineering white papers, capability descriptions, and internal planning documents.
• Support cost and schedule estimation for integration activities by documenting assumptions, dependencies, and engineering workflows.
• Assist leadership with technical briefings, architecture descriptions, and customer‑facing engineering artifacts.

Education Requirements

Bachelor Degree or higher in a related technical field.

Experience Requirements

• 10+ years of experience in systems integration, test engineering, system development, or lab‑based engineering roles.
• Demonstrated experience creating test plans, procedures, verification documents, and technical engineering artifacts.
• Background in hardware/software integration and test system development.
• Experience working within controlled configuration management environments.
• Strong communication, documentation, and organizational skills.
• Active Secret security clearance.
• Experience supporting modeling and simulation programs or digital engineering ecosystems.
• Familiarity with CAD/mesh workflows, model preprocessing, or simulation toolchains.
• Experience with scripting, data collection, or test automation (MATLAB, LabVIEW, Python).
• Knowledge of HWIL/SWIL environments, verification strategies, or model validation techniques.
• Experience contributing to proposals and technical volume development.
• Active TS/SCI.

Applicant Screening

Applicant selected must have an active Secret security clearance and be a U.S. Citizen.
