About The Position

As a Systems Engineer supporting simulation-based training system integration, you will assist in developing and sustaining technical solutions within a government-owned modeling and simulation environment. Working alongside experienced engineers, you will install, configure, and test systems that enable immersive training and mission rehearsal. You will gain hands-on experience supporting prototyping, integration, and troubleshooting across a diverse modeling and simulation ecosystem. Your work may include connecting simulators to distributed simulation environments, supporting technical evaluations, and preparing systems for training events. The role is intended for early-career engineers who want to develop their technical skills, collaborate with multidisciplinary teams, and work with simulation technologies.

Requirements

  • 0–2 years of experience in modeling and simulation, software engineering, computer systems, networking, or related technical fields; internships or coursework are welcome.
  • Basic understanding of networking concepts and protocols.
  • Familiarity with Windows and/or Linux operating systems.
  • Interest in learning simulation frameworks and modeling and simulation integration tools.
  • Strong problem-solving mindset and willingness to ask questions and learn on the job.
  • Good documentation habits and attention to detail.
  • Ability to work both independently and as part of a team.
  • Must be able to obtain a U.S. Security Clearance.

Nice To Haves

Responsibilities

  • Assist with installing, configuring, and maintaining simulation system stacks according to current technical baselines.
  • Help integrate simulators and tools using common networking standards and protocols such as GRID or DIS.
  • Support integration of simulation frameworks and tools (e.g., AFSIM, NGTS, or similar systems) under the guidance of senior team members.
  • Help maintain simulator readiness by following established system configurations and documenting updates or changes.
  • Work with mission partners to support demonstrations, dry runs, and training events.
  • Provide entry-level troubleshooting support across Windows and Linux systems, networks, and simulation tools.
  • Assist team members during hardware setup, system updates, and facility modifications.
