We are seeking a Senior Command and Data Handling (C&DH) Engineer to join our team and take ownership of C&DH test processes, components, and specific mission C&DH subsystems. The C&DH team is responsible for all design, analysis, integration, and testing of C&DH systems on York’s satellites, including in-house designs and purchased systems. This is a systems engineering design/test role, NOT a circuit design role. The ideal candidate will be a C&DH generalist with a strong background in test.

Responsibilities

• Develop and execute test plans and procedures to verify the functionality and performance of C&DH systems, including hardware-in-the-loop (HIL) and software-in-the-loop (SIL) testing.
• Define key performance metrics for C&DH subsystems, including timing, data throughput, signal integrity, and interface compatibility.
• Develop specifications for electrical interfaces (e.g., LVDS, RS422 UART, Ethernet, etc.) and ensure proper signal integrity and performance under environmental conditions (radiation, temperature, etc.).
• Address physical layer issues related to clock distribution, high-speed data lines, and electromagnetic interference (EMI) considerations.
• Design and optimize data flow architecture, ensuring efficient handling of command and telemetry data, including throughput, timing, memory management, error detection/correction, and optimizing bandwidth usage.
• Lead design reviews and participate in system-level trade studies and design trade-offs related to C&DH performance and mission goals.
• Provide technical guidance and expertise during integration activities, ensuring proper alignment with system architecture and performance requirements.
• Troubleshoot issues during test phases, analyze root causes, and implement corrective and preventative actions.
• Monitor the performance of the C&DH system post-launch, ensuring that it meets mission objectives and operational requirements.
• Support anomaly resolution and provide expert input for troubleshooting and system recovery during on-orbit operations.

Minimum Qualifications

• Bachelor’s degree in computer engineering, electrical engineering, computer science, or equivalent degree or experience
• 5+ years of experience in embedded system design and/or test
• Experience with spacecraft C&DH design and/or test
• Must be able to obtain and maintain U.S. security clearance

Desired Qualifications

• Experience with system-level testing and integration (HIL, SIL, automated testing), including hardware/software validation and failure detection.
• Proficiency in systems engineering for space applications, including integration of C&DH subsystems with avionics, payloads, and communications.
• Expertise in high-speed digital circuit design, FPGA/ASIC design, and/or signal integrity analysis for mission-critical systems.
• Strong background in managing data flow, bandwidth allocation, memory management, and real-time data processing in space systems.
• Experience working with bus protocols and interfaces (e.g., I2C, SPI, RS-422).
• Knowledge of managing issues such as rise/fall time, skew, jitter, crosstalk, and data flow management for high-speed, mission-critical systems.
• Deep understanding of space radiation effects on digital electronics and strategies for radiation mitigation.
• Experience in designing and managing systems for precise timing and synchronization in cross-platform environments.
• Familiarity with failure modes in space systems and reliability techniques, including error correction and watchdog timers.
• Proficiency in defining and implementing software interfaces between hardware subsystems and mission software.
• Strong communication skills for coordinating across technical teams and reporting on project status, risks, and mitigations.
