Job description

Company

Millennium Space Systems, a part of Boeing Defense, Space and Security (BDS), is a fast, agile small satellite company focused on national security space. Our missions have direct impact to global security, like missile warning and Earth observation. Our team is curious, bold and innovative. We take risks, innovate and explore new techniques and technologies. We influence change because we challenge the status quo. And when we watch our satellites launch, we know each one of us made it happen.

Job Summary

As a Sr. Environmental Test Engineer, you will develop manufacturing processes to build, test, and launch satellites while dually implementing test procedures for dynamic and thermal environmental testing of components, subsystems, and satellite products. You will be responsible for leveraging design for testability and continuous improvement to deliver space-grade avionics, structures, and propulsion hardware at high rate and low cost, without ever compromising personnel safety or product reliability. A successful candidate for this role will demonstrate integrity, intellectual curiosity, empathy, technical capability, and a strong motivation to scale and support manufacturing test.

Position Responsibilities

• Serve as the primary point of support for environmental test equipment and processes, and maintain responsibility over test execution for spacecraft hardware.
• Create spacecraft hardware test procedures, ensure test readiness, and unblock issues that arise during test campaigns (qualification and acceptance).
• Develop standard operating procedures for environmental test technicians.
• Establish and increase the efficiency of manufacturing test processes to maximize output, limit burden, and enable products to rapidly transition from engineering development to high rate production.
• Identify improvement opportunities and execute initiatives to maintain safe operations, ensure product quality, reduce lead time and labor hours, increase reliability, and qualify environmental test equipment and processes in support of high reliability and throughput production.
• Troubleshoot and identify root cause of issues in environmental test processes (e.g., due to spacecraft hardware defects, test equipment anomalies, software problems) then implement permanent corrective actions to prevent recurrence.
• Enable production autonomy by challenging requirements, simplifying work processes, and implementing automation.
• Serve as the technical subject matter expert for environmental test processes and equipment.
• Develop test equipment automation to improve efficiency of environmental test processes, limit the likelihood of error, and maximize throughput.

Basic Qualifications

• Advanced technical education or equivalent experience in engineering, engineering technology, computer science, engineering data science, mathematics, physics, or chemistry (typically a Bachelor’s degree). ABET accreditation is preferred.
• Experience working with thermal chambers, TVAC chambers, and/or vibration shakers.
• Experience in authoring test procedures and implementing process improvements.
• Ability to obtain a U.S. Security Clearance for which U.S. citizenship is required; a U.S. Security Clearance Post-Start is required.

Preferred Qualifications

• 2+ years of experience in environmental testing, with a focus on vibration, thermal ambient, and thermal vacuum testing.
• Excellent written, verbal communication, and interpersonal skills.
• Managing UUT non-conformances.
• Familiarity with SMC‑S‑016, GSFC‑STD‑7000A, or similar environmental testing standards.
• Experience in a high-throughput manufacturing environment.
• Experience with PXI and other test instrumentation (e.g., thermocouples, accelerometers, DAQs).
• Experience successfully qualifying new products for space applications.
• Thorough understanding of root cause analysis and related analytical methodology (Five Whys, Fishbone/Ishikawa Analysis, 8D).
