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 designed to recognize and reward your contributions. 

- Comprehensive private medical coverage, with dental and optical benefits available, including dependent coverage. 

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

- Semi-annual company-wide parties and regular virtual and team events. 

- Relocation packages available for approved roles. 

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

- Town Halls, Celebration Calls and Frequent company-wide events to stay connected and engaged. 

- We’re a certified Great Place to Work®, five years in a row at our Canadian Headquarters. 

We are seeking a Mechanical Designer to lead the development and verification of spacecraft mechanical subsystems. This role combines mechanical design, structural and thermal analysis, prototyping, testing, manufacturing support, and subsystem integration to deliver flight-ready hardware. The successful candidate will own complete spacecraft mechanical subsystems from concept through qualification, working closely with systems, RF, electrical, software, manufacturing, AIT, and mission operations teams to develop robust and scalable solutions. 

The ideal candidate thrives in environments where performance, mass, manufacturability, reliability, schedule, and cost must all be balanced to achieve mission success. They are equally comfortable performing analysis, building hardware, leading technical discussions, and solving complex multidisciplinary problems.

This role is an opportunity to directly influence the next generation of Kepler spacecraft while helping establish the engineering practices, technical rigor, and culture that will enable Kepler to become a world leader in spacecraft development and space infrastructure.
