Systems Engineer

Oak Ridge, TN
Full Time
Mid Level

Summary:
The Systems Engineer serves as the requirements authority for engineering projects, working at the intersection of design, operations, safety, and quality assurance. You will be responsible for ensuring requirements are complete, measurable, traceable, and properly flow down through system hierarchies, from facility level functional needs through equipment level engineering specifications.
This position requires strong technical judgment to identify requirements quality issues, assess supplier responses for adequacy, and facilitate resolution of technical issues before they impact design, procurement, or operations.

Responsibilities:
Requirements Development & Management

  • Develop and document high-level requirements for new or proposed projects, translating stakeholder needs into technical specifications
  • Facilitate expansion of high-level requirements into traceable lower-level Systems, Structures, and Components (SSCs) requirements with clear parent-child relationships
  • Implement and maintain requirements in systems integration tools (Visure, DOORS, DOORS Next Gen)
  • Establish and enforce requirements quality standards including measurability, testability, traceability, and completeness
Requirements Review & Validation
  • Conduct systematic requirements reviews to ensure clarity of acceptance criteria and verification methods
  • Lead or facilitate requirements reviews to develop baselines and implement design control
  • Evaluate supplier technical responses and design verification records for requirement compliance
  • Identify requirement gaps, conflicts, and traceability issues before they impact downstream activities
  • Review requirements for proper specification of quantitative parameters, units, tolerances, and performance thresholds
Interface Management
  • Define and document interfaces between systems, ensuring both sides of each interface specify performance parameters (flow rates, pressures, temperatures, data protocols, etc.)
  • Coordinate interface requirements across facility systems (electrical, mechanical, controls, safety, etc.)
  • Maintain interface control documentation and facilitate resolution of interface conflicts
Technical Documentation
  • Write and critically review technical documents (Design Interface Requirements, Engineering Design Specifications, Design Verification Records)
  • Ensure requirements include appropriate verification methods (test, analysis, inspection, demonstration)
  • Document requirements changes through formal change control processes
  • Prepare requirements summaries and technical presentations for management and stakeholders
Design Integration Support
  • Support project leads in translating operational needs and safety requirements into equipment design specifications
  • Review equipment designs for compliance, identifying deviations requiring resolution
  • Facilitate design reviews
  • Coordinate with quality assurance to ensure traceability through design, fabrication, and testing
Risk & Cost Management
  • Support project leads in risk identification, monitoring, and documentation
  • Assist in developing cost models for proposed projects based on requirements scope
  • Identify requirements driven cost impacts and facilitate trade off analyses
Process Improvement
  • Develop and maintain systems engineering standards, templates, and best practices
  • Train engineers on requirements quality principles and systems integration tools
  • Implement model-based systems engineering (MBSE) approaches on projects from concept through detailed design
Technical Skills
  • Demonstrated experience developing technical requirements for hardware systems (mechanical, electrical, controls, instrumentation)
  • Strong technical writing skills with ability to translate complex concepts into clear, testable requirements
  • Experience identifying and resolving requirements quality issues including ambiguity, incompleteness, and conflicts
  • Ability to read and understand engineering drawings, P&IDs, electrical schematics, and control system documentation
  • Proficiency in written and oral technical communication and presentation
Systems Engineering Knowledge
  • Understanding of requirements hierarchy and flow-down (functional → performance → design)
  • Knowledge of verification methods and their application
  • Familiarity with interface management principles
  • Experience with requirements traceability and configuration management
Industry Experience
  • Background in hardware based industry with strict workflow and quality assurance standards (nuclear, aerospace, automotive, medical devices, or similar)
  • Experience working with suppliers/vendors to define technical specifications and evaluate design responses
Regulatory & Quality
  • Familiarity with NQA-1, ISO 9001, or equivalent quality control systems
  • Understanding of design control principles and formal change management
Education & Experience
  • Bachelor's degree in engineering or STEM discipline from U.S.-based ABET-accredited university with minimum 3 years relevant experience, OR
  • Master's degree with 1-2 years of model-based systems engineering (MBSE) experience
  • U.S. Citizenship required
  • Ability to obtain and maintain U.S. security clearance preferred

Preferred Qualifications
  • Experience using systems integration software (DOORS, Visure, GENESYS, or similar requirements management tools)
  • Professional Engineer (PE) license or Systems Engineering Professional (CSEP) certification
  • Experience with design verification and validation processes (FAT, SAT, commissioning)
  • Knowledge of hazardous area classifications, safety instrumented systems, or explosion prevention systems
  • Experience in regulated industries requiring formaal requirements management (nuclear, aerospace, FDA regulated)
  • Background in process equipment, manufacturing systems, or production facility design
  • Experience with risk management methodologies and risk tracking
  • Experience with cost estimation and project financial planning
  • Familiarity with relevant codes and standards (ASME, NFPA, OSHA, NEC, ISA)

Benefits:

All eligible employees enjoy an excellent benefits package, including medical/dental/vision insurance, short/long-term disability, life insurance, 401(k), paid time off including holidays, and tuition reimbursement.

Voluntary Self-Identification of Disability
Voluntary Self-Identification of Disability Form CC-305
OMB Control Number 1250-0005
Expires 04/30/2026
Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
