Intone Inc; Northern (KY); Hybrid; USD 120,000 - 160,000; Full time

Job summary

Intone Inc. is seeking an experienced Simulations Software Engineer for a 12-month remote contract based in the United States. You will design and integrate distributed simulators and guide architectural decisions within a complex ecosystem of spacecraft models.

You will mentor engineers, interpret ICDs and hardware specs, and ensure accurate software representations of subsystems while improving existing code and contributing to CI/CD workflows.

Qualifications

• Bachelor's degree in Computer Science, Computer Engineering, Mathematics, Physics, Aerospace Engineering, or a related field; four additional years of relevant experience may substitute for a degree.
• 5+ years of professional software development experience in scientific applications, simulation, or complex technical systems.
• Experience developing distributed simulations, including synchronization, timing coordination, and communication between simulation components.
• Strong programming skills in C++ and/or Python.
• Ability to understand hardware behavior and translate technical specifications and interface documentation into software.
• Experience with Linux, TCP/IP networking, and debugging complex distributed systems.
• Experience maintaining existing codebases, using version control, and developing automated tests.
• Strong communication, collaboration, and technical problem-solving skills.

Responsibilities

• Design, develop, and maintain software models of spacecraft components and subsystems using C++ and Python.
• Develop and integrate distributed simulators using High Level Architecture (HLA), Runtime Infrastructure (RTI), and related simulation technologies.
• Support simulation orchestration, time management, synchronization, and data exchange across interconnected simulators.
• Provide technical guidance on distributed simulation architecture and mentor team members.
• Interpret hardware specifications, Interface Control Documents (ICDs), and technical documentation to create accurate software models.
• Troubleshoot integration, networking, timing, and performance issues across complex simulation environments.
• Maintain and enhance legacy software through code analysis, refactoring, and incremental improvements.
• Develop automated unit, integration, and system tests and deploy changes through established CI/CD pipelines.
• Collaborate with software and systems engineers and participate in technical discussions and customer-facing design reviews.

Job description

We are seeking an experienced Simulations Software Engineer for a 12-month contract position (remote, US-based) to join an aerospace client's team developing spacecraft simulation software. You will help design and integrate distributed simulation environments, guide architectural decisions, and mentor engineers working within a complex ecosystem of interconnected simulators. We welcome candidates from aerospace, defense, and other industries with experience developing distributed simulations or scientific software. Direct spacecraft experience is a plus but is not required.
