Systems Engineer, Senior

Full-Time | Tulsa, OK (Onsite)U.S. Citizenship Required 

We're partnering with an innovative engineering and simulation technology organization seeking a Senior Systems Engineer to join its growing team in Tulsa. This is a high-impact opportunity for an experienced engineer who thrives at the intersection of systems architecture, software, hardware integration, and model-based engineering.

In this role, you'll lead the development of complex simulation and training systems from concept through implementation, helping define system architectures, manage requirements, and ensure successful delivery of advanced technology solutions used in mission-critical environments.

What You'll Do

• Lead systems engineering activities and provide technical direction to multidisciplinary engineering teams.
• Analyze customer, contractual, and operational requirements to develop system concepts and architectures.
• Develop top-level system designs that balance performance, quality, cost, schedule, and technical risk.
• Define and manage hardware/software interface requirements and system integration strategies.
• Conduct engineering trade studies and evaluate alternative technical solutions.
• Identify, assess, and mitigate program and technical risks.
• Decompose system requirements into detailed design requirements and configuration items.
• Develop and maintain requirements traceability throughout the system lifecycle.
• Utilize Model-Based Systems Engineering (MBSE) and Object-Oriented Systems Engineering Method (OOSEM) methodologies.
• Support software and hardware development efforts, including contributions to software development activities when required.
• Participate in system integration, validation, acceptance testing, and troubleshooting.
• Collaborate with software, hardware, manufacturing, and program management teams throughout the project lifecycle.
• Support installation, customer acceptance testing, and deployment activities at customer locations.
• Prepare technical documentation, requirements traceability matrices, design specifications, integration plans, and test procedures.
• Assist with technical proposals, cost estimates, and new business development initiatives.

Technical Leadership Responsibilities

This role provides significant technical leadership responsibilities without direct personnel management duties.

Key responsibilities include:

• Mentoring and supporting junior engineers.
• Conducting design reviews and peer reviews.
• Promoting engineering best practices and systems engineering discipline.
• Facilitating collaboration across engineering teams and stakeholders.
• Supporting onboarding and knowledge transfer efforts.
• Identifying process improvements and technical efficiencies.
• Assisting project leadership with technical planning, execution, and risk management.

What We're Looking For

Required Qualifications

• Bachelor's degree in Engineering, Computer Science, Physics, Mathematics, or a related technical discipline.
• Minimum of 4 years of experience in systems engineering, simulation, modeling, or related engineering environments.
• Experience developing and managing complex system requirements.
• Hands-on experience with MBSE methodologies and OOSEM principles.
• Experience creating and maintaining requirements traceability.
• Knowledge of systems architecture, integration, validation, and verification processes.
• Familiarity with software and hardware development lifecycles.
• Experience with configuration management and version control tools such as Git or Subversion.
• Understanding of computer networking and system architectures.
• Strong analytical, problem-solving, and troubleshooting skills.
• Excellent communication and technical documentation abilities.

Preferred Qualifications

• Experience in simulation, training systems, aerospace, defense, or government contracting environments.
• Experience using MBSE tools such as Cameo Systems Modeler, DOORS, or similar requirements management platforms.
• Exposure to software development using languages such as C, C++, Python, Fortran, C#, or Ada.
• Experience working within Linux operating environments.
• Knowledge of hardware/software integration and system-level performance analysis.
• Experience supporting customer-facing demonstrations, testing, and deployments.

Technical Environment

Successful candidates may have experience with:

• Model-Based Systems Engineering (MBSE)
• OOSEM methodologies
• Requirements management and traceability
• Cameo Systems Modeler
• DOORS
• Git and Subversion
• Linux and Windows operating systems
• Simulation and training systems
• Software and hardware integration
• Networked system architectures

Travel

• Approximately 25% travel.
• Domestic travel throughout the United States with occasional international assignments.
• Travel may involve customer acceptance testing, installation support, and user training.
• Trips may range from several days to multiple weeks and may occasionally include weekends.
• Ability to obtain and maintain a valid passport may be required.

Work Schedule

• Standard Monday through Friday work schedule.
• Flexibility to support project milestones, integration events, and customer requirements when additional hours are needed.
• Occasional weekend, holiday, or alternate-shift work may be required.

Security Requirements

• U.S. Citizenship is required.
• Must be eligible to obtain and maintain a U.S. Department of Defense security clearance.

Why This Opportunity Stands Out

• Work on sophisticated simulation and training technologies supporting mission-critical applications.
• Influence system architecture and engineering decisions from concept through deployment.
• Collaborate with highly skilled multidisciplinary engineering teams.
• Gain exposure to advanced MBSE practices, complex integrations, and customer-facing engineering projects.
• Strong opportunity for technical leadership and long-term career growth.
