Senior Mechanical Designer

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!

We are seeking a Senior Mechanical Designer to define the architecture and technical direction of major spacecraft mechanical subsystems across multiple programs.

This role combines subsystem architecture, mechanical design, structural and thermal analysis, hardware development, technical leadership, and cross-functional collaboration to deliver scalable spacecraft solutions that enable Kepler's next generation of products. The successful candidate will remain deeply engaged in solving the organization's most challenging mechanical engineering problems while guiding subsystem owners, systems engineering, manufacturing, and technical specialists to establish robust, reusable, and manufacturable designs.

The ideal candidate thrives in environments where performance, mass, manufacturability, reliability, schedule, and cost must all be balanced across multiple programs. They combine deep technical expertise with strong systems thinking and influence engineering decisions through technical leadership, engineering judgment, and mentorship rather than organizational authority.

This role is an opportunity to shape the mechanical architectures, engineering methodologies, and technical capability that will enable Kepler to become a world leader in spacecraft development and space infrastructure.
