Senior Software Engineer SIM

Sceye is a high-growth technology company, building the next generation of instant communications, imaging and remote sensing infrastructure through stratospheric platforms.

Our lighter-than-air high-altitude platform systems (LTA HAPS) are capable of maintaining position over an operational area in the stratosphere (altitudes of 18 – 21km). They can carry multiple telecommunications, imaging and remote sensing payloads, providing unique functionality, cost, environmental and societal advantages.

Our HAPS be deployed in a matter of days and at a fraction of the cost of traditional infrastructure solutions. This makes them an ideal solution for providing telecommunications connectivity, emergency solutions in the event of natural or other disasters, environmental and infrastructure monitoring, Earth observation and a range of defense applications.

Our customers & partners include some of the largest global telecommunications companies, infrastructure operators, climate researchers, civil and defense agencies. At Sceye, we aim high, and we want you to join us at the stratospheric edge of innovation. As part of our mission-driven team, you’ll contribute to building breakthrough technologies that are changing the way we connect and observe the world.

We are looking for individuals who bring not only deep expertise but also bold vision and an unwavering commitment to excellence.

Sceye is seeking a Senior Software Engineer to support the development and evolution of SCEYE-SIM, our simulation and software environment critical to flight systems testing, validation, and mission readiness.

• Improve software performance, reliability, and scalability to support current and future flight campaigns
• Support flight readiness activities, including analysis and troubleshooting of simulation and test data
• Contribute to architectural decisions, coding standards, and best practices across the software team
• Mentor junior engineers and interns, providing technical guidance and code reviews
• Assist in de-risking future hardware and software development cycles through thoughtful design and prototyping

• Bachelor’s degree in Computer Science, Software Engineering, or related field (Master’s preferred)
• 7+ years of professional software engineering experience
• Strong proficiency in one or more systems-level programming languages (e.g., C/C++, Python, Rust, or similar)
• Experience working with simulation environments, avionics software, or aerospace systems
• Solid understanding of networking concepts and distributed systems
• Experience working in Linux-based development environments
• Strong problem-solving skills and ability to work in a fast-paced, multidisciplinary environment
