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 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.
As an RF Designer, your focus will be on RF hardware development, specifically hardware related to both our space-based communications payloads as well as ground-based assets. You will have the opportunity to work on everything from high-gain phased array antennas to software-defined radio transceivers.
We are looking for exceptional candidates with the below experience along with any unique abilities that could be used to augment our small but strong RF team.

Required Skills & Qualifications:

    • Bachelor’s degree in electrical engineering, physics, or equivalent. Graduate’s degree is desirable

    • 5+ years' experience with RF circuit and/or antenna design

    • 5+ years' experience with RF circuit simulation tools (ADS, Microwave Office etc.) and PCB layout tools (Altium, Cadence etc.)

    • Proficient in basic RF circuits concepts such as impedance matching, smith chart, network analysis, active and passive microwave components and systems (mixers, amplifiers, transistors at RF frequencies) and their figures of merit (P1dB, Psat, IIP3, noise figure, etc.), RF filter design

    • Familiarity with RF radio architectures and components

    • Competence with basic electrical PCB design (power distribution, analog circuits, basic sequencing, etc.)

    • Comfortable making RF measurements using standard RF test equipment: spectrum analyzers, vector network analyzers, noise and power measurements

Key Responsibilities:

    • Take spacecraft and ground terminal RF Hardware from conception to design, manufacturing, test, and on-orbit operations

    • Design and simulate RF subsystems (filters, amplifiers, transitions etc.)

    • Perform component selection for frontend circuits

    • Perform schematic capture, layout and fabrication support of RF frontend PCBAs and antennas

    • Contribute to trade studies and designs of radio systems from a hardware perspective

Bonus Points

    • Experience working closely with PA MMIC’s: matching, tuning, testing etc. is desirable

    • Knowledge/familiarity with modulation, DSP, or digital radio concepts is desirable

    • Experience with Altium Designer is desirable

    • Experience with antenna design in CST or equivalent is desirable

    • Familiarity with ADCs/DACs/RFSoC/SDR desirable

Salary Range: $113,474 - $163,474 CAD
