SIM Lead

Job Description

Sceye SIM Lead

Status: Full Time

Location: San Francisco Bay Area, CA / Moriarty, NM

Reports To: Software Lead

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 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 Sceye SIM Lead to own our simulation environment for the HAPS flight platform. Our simulation ('SIM') systems replicate vehicle dynamics, avionics, and mission software so engineers can safely develop, test, and validate new capabilities before they ever fly in the stratosphere. This role leads a growing team building high-fidelity, real-time simulation tools that are central to Sceye's flight test and software development lifecycle.

• Lead the design, development, and maintenance of Sceye’s flight and systems simulation environment.
• Manage and mentor a team of simulation and software engineers.
• Build high-fidelity models of vehicle dynamics, avionics, sensors, and communications payloads for use in software-in-the-loop and hardware-in-the-loop testing.
• Partner with Avionics, Flight Software, and Flight Test teams to define simulation requirements that support upcoming missions.
• Ensure simulation environments accurately reflect real vehicle behavior, including edge cases and failure modes.
• Integrate simulation tools into CI/CD pipelines to support automated regression testing of flight software.
• Own tooling for scenario generation, telemetry playback, and mission rehearsal.
• Drive continuous improvement of simulation fidelity based on flight test data.
• Coordinate with Mission Operations to support pre-flight readiness reviews using simulation results.
• Document simulation architecture, assumptions, and validation methods.

• Bachelor’s degree in Computer Science, Aerospace Engineering, Electrical Engineering, or related field;
  Master’s preferred.
• 7+ years of software engineering experience, including 2+ years in a technical leadership or team lead capacity.
• Strong experience building simulation, modeling, or digital-twin systems for aerospace, robotics, or similarly complex physical systems.
• Proficiency in C++ and/or Python for real-time simulation development.
• Solid understanding of vehicle dynamics, control systems, or guidance/navigation concepts.
• Experience with software-in-the-loop (SIL) and hardware-in-the-loop (HIL) test environments.
• Strong leadership and communication skills with experience managing engineers.

• Experience with flight simulation frameworks (e.g., custom or commercial modeling & simulation platforms, MATLAB/Simulink, JSBSim).
• Background in lighter-than-air vehicles, UAS, satellites, or other high-altitude or aerospace platforms.
• Experience integrating simulation with CI/CD and automated test pipelines.
• Familiarity with real-time…
