Kepler Communications operates the first commercial optical data relay constellation with 33 satellites launched to date, providing real-time on-orbit connectivity for critical missions. As a Senior Spectrum Engineer, you will serve as a technical authority on spectrum engineering, frequency coordination, and regulatory compliance for Kepler's low-Earth orbit satellite communications systems.
You will work under the Regulatory team and collaborate closely with Systems Engineering, RF, Antenna, Mission Design, and Software teams to translate complex International Telecommunication Union (ITU) regulations into practical system requirements and technical solutions. Your role bridges regulatory requirements, frequency-coordination considerations, and interference constraints into Kepler's system architecture, analytical models, and resource-management capabilities.
Key responsibilities include:
- Serve as technical authority on spectrum engineering, frequency coordination, and regulatory compliance for satellite systems
- Lead development and maintenance of system models incorporating spectrum regulations, coordination requirements, interference constraints, and operational scenarios
- Define and implement spectrum-related functionality within satellite resource-management and mission-planning software
- Identify spectrum risks, constraints, and optimization opportunities
- Lead technical assessments involving emission masks, antenna characteristics, RF propagation, interference, link performance, and mission profiles
- Conduct compatibility, sharing, and interference analyses involving NGSO, GSO, terrestrial, and other communications systems
- Support technical work related to frequency-coordination activities and regulatory submissions to ITU and national administrations
- Develop, verify, and maintain software tools for evaluating regulatory compliance and system performance
- Establish analysis methodologies, assumptions, validation practices, and documentation standards
- Identify spectrum-related technical and regulatory risks and develop mitigation strategies with internal stakeholders
Kepler offers competitive compensation with equity, comprehensive health/dental/vision coverage, unlimited vacation, parental leave, professional development funding ($1,500 annually), and a fully stocked Toronto office. The company is a certified Great Place to Work for seven consecutive years.
REQUIREMENTS:
- Bachelor's degree in Electrical Engineering, Telecommunications Engineering, Systems Engineering, Space Engineering, or related discipline
- At least 7 years of relevant engineering experience, including substantial experience in spectrum engineering, satellite communications, RF systems, or frequency coordination
- Strong understanding of orbital mechanics, RF propagation, link analysis, digital communications, antenna systems, and interference modeling
- Demonstrated experience interpreting and applying ITU Radio Regulations, ITU-R Recommendations, or comparable spectrum regulations
- Familiarity with international spectrum regulatory frameworks
- Experience conducting interference, compatibility, and spectrum-sharing analyses for satellite or terrestrial communication systems
- Strong proficiency with programming languages such as C/C++, Python, or MATLAB
- Experience developing, validating, and maintaining technical software or system models
- Ability to lead complex technical investigations and translate findings into clear recommendations and system requirements
- Strong technical writing, presentation, and stakeholder-management skills
- Ability to work independently while providing technical leadership across multidisciplinary teams
BONUS QUALIFICATIONS:
- Master's degree in relevant engineering discipline
- Direct experience with NGSO or LEO satellite constellation design and operations
- Experience preparing or supporting ITU filings, frequency-coordination agreements, or submissions to national regulatory authorities
- Experience with Systems Tool Kit (STK) or comparable mission-analysis software
- Familiarity with satellite resource-management, beam-planning, gateway-planning, or dynamic spectrum-allocation systems
- Experience with Git, automated testing, continuous integration, or formal software-release processes
