## Description

We are looking for a Software Simulation Engineer to design and build the core architecture of our simulation platform. You will be responsible for the infrastructure that validates our intelligent systems before real-world deployment.

Your focus will be on creating a scalable, high-performance virtual environment that seamlessly integrates flight software, autonomy stacks, and external models.

Key responsibilities include:

- Design, build, and maintain the core infrastructure, data pipelines, and timing mechanisms for our system-level and Software-in-the-Loop (SIL) simulation environments.

- Build robust APIs and interfaces that allow cross-functional teams to easily plug their specific sensor, actuator, and physics models into the broader simulation.

- Integrate flight software, autonomy stacks, and control algorithms directly into the simulator.

- Develop the backend tooling and automated test frameworks needed to run large-scale simulations, verify system behavior, and catch edge cases.

- Act as the simulation platform owner, partnering with hardware and controls teams to ensure the architecture supports their testing requirements and scales effectively.

Requirements:

- BS or MS in Computer Science, Software Engineering, Systems Engineering, or a related field.

- 3+ years of experience in software simulation, systems architecture, or complex software development.

- Expert in Python with strong working knowledge of C++.

- Hands-on experience architecting, extending, or maintaining custom software simulators, test harnesses, or large-scale software frameworks.

- Solid understanding of system-level networking and data routing (e.g., Ethernet, UDP/TCP, CAN).

Bonus:

- Background in aerospace, automotive, or robotics.

- Familiarity with Embedded Linux, RTOS, or supporting downstream Hardware-in-the-Loop (HIL) setups.

- Experience with CI/CD pipelines and scaling simulations in cloud environments.

What we offer:

All our positions offer a compensation package that includes equity and robust benefits. Base pay is just one component of Astranis's total rewards package. Your compensation also includes a significant equity package via incentive stock options, high-quality company-subsidized healthcare, disability and life insurance, 401(k) retirement planning, flexible PTO, and free on-site catered meals.

Astranis pay ranges are informed and defined through professional-grade salary surveys and compensation data sources. The actual base salary offered to a successful candidate will additionally be influenced by a variety of factors including experience, credentials & certifications, educational attainment, skill level requirements, and the level and scope of the position.

Base Salary: $125,000-$170,000 USD

U.S. Citizenship, Lawful Permanent Residency, or Refugee/Asylee Status Required (To comply with U.S. Government space technology export regulations, applicant must be a U.S. citizen, lawful permanent resident of the United States, or other protected individual as defined by 8 U.S.C. 1324b(a)(3))

Our mission and our products are meant to connect the world and everyone in it, regardless of gender, race, creed, or any other distinction. We believe in a diverse and inclusive workplace, and we encourage all people to join our team and bring their unique perspective to help make us stronger.
