Insitu is looking for an enthusiastic and experienced and highly capable Simulation Software Engineer to be part of an agile software development team advancing Insitu’s unmanned aircraft systems. This role is a unique opportunity to develop software and simulation systems for complex challenging problems, including aircraft and payload system’s simulation.

You’ll join a small, tightly integrated team responsible for the development of a full-stack software solution with a focus on simulation software and modelling. Ideal candidates are exceptional problem solvers, comfortable operating at the intersection of software, physics, and math.

We value curiosity, initiative, and the ability to work independently while collaborating deeply with adjacent teams in flight software and integration.

As a senior member of the Software Engineering Department operating on the simulation team you will:

• Design, develop and test simulation software using modern programming languages and best practices for scalability and reusability.
• Develop modular simulation physics components, including models for aerodynamics, actuators, payloads, and environmental effects.
• Collaborate with system engineers, simulation developers, and airframe designers to align software architecture with aircraft requirements.
• Design, implement, and optimize simulations of physical, digital, or hybrid systems based on project requirements.
• Leverage AI tools and machine learning techniques to enhance simulation fidelity, automate modeling processes, or analyze simulation outputs.
• Work closely with domain experts, engineers, data scientists, and other stakeholders to integrate simulations—and AI-enhanced features—into engineering workflows or customer solutions.
• Produce clear technical documentation, user guides, and maintain code repositories.
• Stay current with advancements in simulation technologies; propose and integrate novel approaches or tools.

Our software engineers can work remotely or at our engineering building in Bingen, Washington. This position supports either option, with a preference for fully on-site or hybrid. The Gorge is a mecca for outdoor sports such as windsurfing, kiteboarding, mountain biking, hiking and skiing (plus many more). If you're passionate about what you do and want to live and work in an amazing place this is a great opportunity.

 Required skills:

• Strong background in simulation development using MathWorks tools (MATLAB, Simulink, Simulink Coder, Simulink Real-Time etc), developing and optimizing simulation or modeling software.
• Strong background in modular design patterns and object-oriented programming using C++ or C#.
• Strong foundation in mathematics, physics, or systems modeling.
• Familiarity with fixed-wing and/or rotorcraft aerodynamics.
• Excellent modeling, software, and debugging skills
• Experience with safety critical systems desired
• Experience with version control (e.g., Git) and collaborative development workflows.
• Excellent problem-solving skills and attention to detail.
• Effective communication and teamwork skills.

Education & Experience

Bachelor's degree of Science from an accredited course of study, in engineering or computer science. Typical experience: 5-8 years in an engineering classification with a Bachelor's degree or 3-6 years’ experience in an engineering classification with a Master's degree.
