Responsibilities

Develop C&DH subsystem architectures for Millennium’s space vehicle, driving system level design decisions and maintaining alignment with mission objectives and constraints.
Select avionics and onboard processing units that meet flight software (FSW) and data handling needs while balancing performance, power, mass, and cost.
Perform requirements definition and flow down, develop interface requirements, and manage verification activities.
Lead the identification and resolution of technical issues related to avionics and electrical hardware during design, integration, and testing phases.
Create and maintain detailed netlists to define the vehicle’s electrical connectivity.
Perform data budget analysis and guarantee positive margins for telemetry, command, and onboard processing streams throughout the mission lifecycle.
Conduct signal integrity (SI) studies to inform transmission line designs.
Validate C&DH architectures against program fault management requirements, incorporating redundancy, watchdogs, and error detection mechanisms.
Select and analyze oscillators and clock distribution schemes to meet timing requirements; perform clock drift, jitter, and accuracy analyses.
Analyze serial and analog interfaces for compatibility, signal levels, grounding, and EMI considerations.
Own vendor selection and trade study activities; produce make/buy recommendations that balance cost, schedule, technical risk, and lifecycle support.
Collaborate with Flight Software, Harness, Electrical Ground Support Equipment and other multidisciplinary subsystem teams providing C&DH expertise as needed
Provide technical, cost, and schedule status updates to program leads and functional managers; present C&DH designs, trade‑offs, and risk mitigations at SRR, PDR, CDR, and other customer reviews.
