As a Senior Spectrum Engineer at Kepler,



you will play a leading role in ensuring that our next-generation low-Earth orbit satellite communications systems are designed and operated in alignment with global spectrum regulations. You will integrate regulatory requirements, frequency-coordination considerations, and interference constraints into Kepler’s system architecture, analytical models, and resource-management capabilities. Working under Regulatory and supporting cross-functional teams such as the Systems Engineering, RF, Antenna, Mission Design, and Software teams, you will translate complex International Telecommunication Union (ITU) regulations into practical system requirements and technical solutions. You will lead critical analyses, influence system-level design decisions, and provide technical guidance on spectrum strategy, compliance, and performance optimization.

Key Responsibilities: Serve as a technical authority on spectrum engineering, frequency coordination, and regulatory compliance for Kepler’s satellite systems

Lead the 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 launch-to-operational-orbit 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 the ITU and national administrations

Develop, verify, and maintain software tools used to evaluate 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 in partnership with internal stakeholders

Required Skills & Qualifications: Bachelor’s degree in Electrical Engineering, Telecommunications Engineering, Systems Engineering, Space Engineering, or a related discipline

At least seven years of relevant engineering experience, including substantial experience in spectrum engineering, satellite communications, RF systems, or frequency coordination

Solid 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 program
