At Kepler Communications, we're not just imagining the future of on-demand space connectivity - we're leading it!

Our mission is to provide real-time Internet access for space-based assets, enabling a new era of data-driven exploration and innovation. With 33 satellites launched to date, Kepler operates the first commercial optical data relay constellation, enabling real-time, continuous space communications while supporting advanced on-orbit compute and hosted payload capabilities.

Industry-leading technology is only part of the story. What sets Kepler apart is our team: bold thinkers, skilled builders, and passionate problem-solvers who thrive on pushing the boundaries of what’s possible in space. We believe great ideas come from diverse perspectives, and we’re committed to creating an environment where you can grow, lead, and make a global impact.

If you’re ready to reach higher, move faster, and do work that shapes the future space economy - this is your launchpad. Come build the future with Kepler!

What We Offer:

* Competitive compensation with a robust equity plan to share in our success.

* Comprehensive coverage for health, dental, and vision insurance—including dependents.

* Unlimited vacation, supportive parental leave policy, and company-wide holiday shutdown.

* Semi-annual company-wide parties and frequent in-office team events.

* Relocation packages available for approved roles.

* $1,500 annual professional development fund to support your growth.

* Fully stocked Toronto office kitchen with snacks, drinks, games and top-notch kitchen appliances.

* Town Halls, Celebration Calls, and Company-wide events to stay connected and engaged.

* We’re a certified Great Place to Work®, five years in a row!

As a Senior Modeling & Simulation (M&S) Engineer, you will develop models, tools, and simulations of next-generation space systems. The products you develop will form the backbone of a high-performance space systems team, aligning requirements and specifications from early mission analysis through spacecraft design, manufacturing, and in-space operations.

You will work with subject matter experts across space systems engineering, flight software, manufacturing, and mission operations to continuously improve systems models and digital twins. Applying modern software development practices and technology, you will deliver scalable solutions which enable rapid mission analysis and superior technical decision making. You will be a force-multiplier within the Solutions Architecture team, empowering the rapid development and deployment of next-generation spacecraft, high-speed optical communications networks, and space technology.

The ideal candidate possesses experience developing high-quality, scalable software systems within a small cross-functional team. They enjoy learning from subject matter experts across a broad range of technical domains, and can distill complex systems concepts into concise, elegant solutions. They love to experiment, prototype, and use new tools and technology (including AI) to learn, grow, and improve. Success in this role requires creativity, curiosity, pragmatism, and collaboration.
