Systems Engineer

Aptima

About the Role

Aptima is a technological leader in the national security industry, engineering scalable solutions that fuse technological innovation with human potential to transform training, development, and performance in mission-critical environments. This role supports simulation-based system integration, assisting in the development and sustainment of technical solutions within a government-owned modeling and simulation (M&S) environment.

How You Will Make An Impact

• Assist in the development and sustainment of technical solutions within a government-owned modeling and simulation (M&S) environment.
• Install, configure, and test systems that enable immersive training and mission rehearsal.
• Gain hands-on experience supporting prototyping, integration, and troubleshooting activities across a diverse M&S ecosystem.
• Contribute to operator training and readiness by helping connect simulators, supporting technical evaluations, and preparing systems for training events.
• This role is ideal for early-career engineers eager to grow their technical skills, collaborate with multidisciplinary teams, and work with cutting-edge simulation technologies.

Key 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.

Requirements & Tech Stack

• 100% on-site at the Dayton, OH customer location.
• Basic understanding of networking concepts and protocols.
• Familiarity with Windows and/or Linux operating systems.
• Interest in learning simulation frameworks and M&S 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.

Qualifications

• 0–2 years of experience in modeling & simulation, software engineering, computer systems, networking, or related technical fields (internships or coursework welcome).
• DoD 8140 IAT Level II compliance (e.g., Security+) preferred or ability to obtain within a reasonable timeframe.
