## Description

As a Senior Spacecraft Command and Data Handling (C&DH) Engineer, you will serve as a primary technical authority for the electrical hardware and avionics architectures critical to Millennium's space vehicles.

You will drive the strategic design of vehicle architectures, ensuring they meet complex mission requirements while optimizing for performance, manufacturability, and cost.

Responsibilities:

- Architect C&DH subsystem architectures that drive system-level design decisions and ensure alignment with mission objectives, constraints, and fault management requirements

- Lead the selection and trade analysis of avionics architectures to balance mission requirements with performance, power, mass, and cost

- Drive the definition of requirements, interface control documents, and verification activities

- Direct high-fidelity analyses for data budgets, signal integrity, clock drift, jitter, and EMI/EMC compatibility to guarantee design margins and reliability

- Own vendor selection and trade studies, producing make/buy recommendations that balance technical risk, schedule, cost, and long-term lifecycle support

- Lead the identification and resolution of complex technical issues related to avionics and electrical hardware throughout the design, integration, and testing phases

- Collaborate on Fault Detection, Isolation, and Recovery (FDIR) strategies, ensuring architectures are resilient and providing technical expertise for mission operations and system health assessment

- Mentor junior and mid-level engineers to foster technical excellence and scale the group's engineering capabilities

- 7+ years of experience in the design, analysis, and integration of spacecraft electrical hardware or complex avionics systems

- This position requires the ability to obtain a U.S. Security Clearance for which the U.S. Government requires U.S. Citizenship. A final U.S. Security Clearance Post-Start is required

Preferred Qualifications:

- Level 5: 14 or more years' related work experience or an equivalent combination of technical education and experience

- Experience as a Responsible Engineering Authority (REA) or Lead Engineer on complex space programs

- Deep familiarity with industry standards and DoD/government cybersecurity implementation for space assets

- Experience in high-rate manufacturing environments

- Advanced degree (M.S. or Ph.D.) in a relevant engineering discipline

- Outstanding communication and presentation skills

Benefits:
