Spacecraft represent the most pressing unmet need across the entire aerospace industry. As more launch vehicles come online and the cost to orbit decreases, more companies launching payloads to space continue to emerge. For the first time in history, this influx of payload companies combined with reduced launch costs has resulted in a massive increase in need for commercial spacecraft platforms, known as satellite buses. These buses hold the payloads of our customers and are flown on launch vehicles. Apex manufactures these satellite buses at scale using a combination of software, vertical integration, and hardware that is designed for manufacturing. Our spacecraft enable the future of society: ranging from earth observation to communications and more. We’d love for you to join us on our mission of providing humankind access to the galaxy beyond our planet. About the Role As the Mission Operations & Mission Assurance Chief Engineer, your responsibilities include providing technical leadership for spacecraft on-orbit operations, anomaly investigations, failure review boards, and root cause corrective action (RCCA) across the Apex satellite constellation. You will be the central technical authority for identifying, investigating, mitigating, and resolving spacecraft anomalies and mission-critical issues. The successful candidate will work cross-functionally with Mission Operations, Systems Engineering, Reliability, Flight Software, Avionics, Guidance, Navigation & Control (GNC), Propulsion, Power, Thermal, Manufacturing, and Test teams to ensure timely anomaly resolution, disciplined technical investigations, and continuous improvement of spacecraft reliability. The ideal candidate combines deep spacecraft systems knowledge, hands-on mission operations experience, structured failure investigation expertise, and the ability to make sound technical decisions in time-critical operational environments. Responsibilities • Serve as the primary engineering focal point for on-orbit spacecraft anomalies, performance degradation, subsystem failures, and mission-threatening events • Direct anomaly triage, fault isolation, technical troubleshooting, and recovery planning in coordination with Mission Operations and subsystem engineering teams • Lead Root Cause and Corrective Action (RCCA) investigations to identify failure mechanisms, determine root causes, assess mission impacts, and develop corrective and preventive actions • Apply systematic problem-solving methodologies, including Fault Tree Analysis (FTA), Failure Modes and Effects Analysis (FMEA), and statistical reliability assessments • Following RCCA, evaluate anomaly implications across the broader satellite fleet, including common-cause failures, systemic design deficiencies, and latent reliability risks • Provide technical recommendations for spacecraft recovery, operational workarounds, fault-management changes, and continued mission operations • Evaluate the adequacy of verification and validation activities associated with corrective actions and mission-critical changes • Ensure clear traceability between on-orbit anomalies, root cause findings, corrective actions, verification evidence, and final technical disposition • Establish and maintain structured investigation processes, including evidence collection, failure reconstruction, causal analysis, root cause verification, and corrective action closure. This includes: (1) how to analyze spacecraft telemetry, command histories, event logs, flight software behavior, and operational trends to identify anomalous conditions and reconstruct failure sequences, (2) establish anomaly severity classifications, escalation criteria, investigation priorities, and technical response expectations • Establish and track key mission assurance indicators, including anomaly recurrence rates, investigation closure performance, fleet failure trends, and corrective action effectiveness • Develop and communicate technical investigation findings, risk assessments, and closure recommendations to engineering leadership and executive stakeholders • Translate on-orbit failure data into actionable design improvements, updated requirements, qualification testing, screening strategies, and operational safeguards • Provide independent technical reviews and assessments of future products to ensure high likelihood of mission assurance, including at design and pre-ship reviews Minimum Qualifications • Bachelor's degree in Aerospace Engineering, Electrical Engineering, Mechanical Engineering, Systems Engineering, Computer Engineering, Physics, or a closely related technical discipline • 10+ years of relevant engineering experience in spacecraft development, satellite systems engineering, mission operations, reliability engineering, or mission assurance • 5+ years of experience supporting spacecraft mission operations, complex aerospace system troubleshooting, failure investigations, or anomaly resolution • Demonstrated experience leading multidisciplinary technical investigations, failure review boards, or structured RCCA activities involving complex hardware/software systems • Strong systems-level understanding of spacecraft architectures, subsystem interfaces, failure modes, and operational dependencies • Experience analyzing engineering telemetry, test data, event logs, and other technical evidence to reconstruct failures and develop defensible root cause conclusions • Working knowledge of structured reliability and failure investigation methodologies, including FMEA/FMECA • Demonstrated ability to assess technical risks, develop mitigation strategies, and communicate recommendations under schedule pressure or operational uncertainty • Experience coordinating engineering activities across multiple technical disciplines and influencing stakeholders without direct reporting authority • Strong technical writing and communication skills, including experience presenting complex investigation findings and risk assessments to
