We are looking for an Avionics Architect to lead the system architecture of Kepler’s next-generation satellite avionics platform. This role will define and drive the end-to-end avionics architecture for a complex spacecraft that combines a high-speed networking payload, an On-Board Computer (OBC), and interfaces to a sophisticated Guidance, Navigation, and Control (GNC) sensor and actuator suite.

The ideal candidate brings deep experience in high-speed digital or networking equipment architecture and can translate mission and product requirements into a robust, scalable, and recoverable avionics system that balances performance, reliability, operability, and development risk.

Key Responsibilities:
•
Own the top-level avionics architecture for a satellite platform, including system decomposition, interface strategy, and architectural trade studies across the OBC, payload with a focus on security, reliability, serviceability, and scalability

•
Define architectures that support high-speed networking payloads (up to 100G), backplanes, management networks, timing/clock distribution, system boot and recovery concepts

•
Lead the design of robust Failure Detection, Isolation, and Recovery (FDIR), including safe-mode behavior, degraded operation, watchdog strategies, firmware recovery, and contingency operations across the spacecraft

•
Document and maintain the avionics technical baseline, including architecture diagrams, interface definitions, trade studies, operating modes, and design justifications.

•
Provide technical leadership through architecture reviews, subsystem design reviews, integration planning, anomaly resolution, and roadmap development for future designs

•
Perform and guide engineering analyses, including derating, reliability, radiation tolerance, single-point failure analysis, EMI/EMC, signal integrity, power distribution concepts, and FMECA-informed design improvements

•
Work cross-functionally with networking, GNC, RF, software, FPGA, systems, AIT, and mechanical/thermal teams

•
Support supplier and component selection for critical avionics functions, especially in high-speed interconnect, timing, compute, FPGA/SoC, memory, and networking subsystems

•
Represent Electrical Engineering at internal and external design reviews.

•
Stay current with emerging technologies, standards, and best practices in space and high-performance electrical systems

Required Skills & Qualifications::
•
Bachelor's Degree in Electrical Engineering or equivalent; Master's Degree is an asset

•
10+ years of experience in spacecraft avionics, high-speed digital electronics, network equipment, or other complex embedded hardware systems, with significant experience at the architecture or technical lead level

•
Demonstrated experience architecting complex multi-board or distributed systems that combine processors, FPGAs/SoCs, management controllers, storage, power distribution, and high-speed interfaces

•
Strong background in high-speed networking architecture or networking equipment design, including experience with Ethernet switching or routing systems up to 100G-class links

•
Experience with system architecture for compute platforms using modern SoCs, FPGAs, and memories such as QSPI NOR, eMMC, DDR4, SATA, NVMe, or similar technologies

•
Strong understanding of reliability and operability considerations, including FDIR, watchdog and reset strategies, boot architecture, firmware update and recovery concepts, redundancy, and fault containment

•
Experience conducting engineering analyses such as FMECA/FMEA, worst-case analysis, radiation effects mitigation, EMI/EMC, signal integrity, and power architecture trade-offs

•
Ability to evaluate architectural trade-offs across performance, thermal constraints, electrical power, manufacturability, testability, schedule, and mission risk

•
Experience working in fast-paced development environments where requirements evolve, including driving early design decisions and validating key architectural assumptions

•
Strong communication skills and ability to produce clear, thorough technical documentation and present architectural decisions to cross-functional engineering leadership

•
Comfortable operating across system-level architecture and detailed interface design, from early concept development through integration and validation

Bonus Points :
•
Experience working in an aerospace or high-reliability (high-rel) environment

•
Experience designing hardware/systems to operate in a radiation environment

•
Low-level electrical design, high-speed layout

•
Experience working with Altium

•
Experience with space standards (NASA or ECSS)

Use of AI in Recruitment
