Senior RAMS Engineer (Reliability, Availability, Maintainability & Safety)

<p>ReOrbit is looking for an experienced RAMS engineer to lead the definition, analysis, and verification of reliability and availability across our satellite systems. This role is critical to ensuring that mission and service reliability targets are technically sound, operationally realistic, and effectively integrated into system design decisions throughout the program lifecycle.</p><p>As our Senior RAMS Engineer, you will own the development and maintenance of system-level reliability models, fault trees, and availability assessments that guide architecture, redundancy, and risk mitigation strategies. Working closely with systems, avionics, software, and operations teams, you will provide quantitative insight into mission-critical failure drivers and ensure RAMS activities remain pragmatic, adaptable, and closely aligned with fast-evolving spacecraft designs.</p><p><br>It's an exciting chance to join a dynamic start-up, with the opportunity to make a real impact, to reach our goal of pushing the boundaries of space data transfer.&nbsp;</p><p><strong>Responsibilities</strong></p><ul><li><p>Define and own Satellite‑level Reliability and Availability targets, ensuring they are technically justified, demonstrably verifiable, and flexible enough to accommodate design evolution.</p></li><li><p>Develop and maintain the system‑level Reliability model, including Fault Tree (FT) structures, allocations, and quantitative assessments used to verify compliance with Rel &amp; Avail targets.</p></li><li><p>Estimate and track Availability of the service, explicitly accounting for recoverable failures through MTBF and MTTR modelling, and ensuring assumptions are operationally credible.</p></li><li><p>Identify and quantify the main contributors to mission failure, providing clear, prioritized inputs to system design, risk mitigation, and decision‑making.</p></li><li><p>Lead and execute RAMS analyses across the program lifecycle, including FTA, Reliability Allocation, FMECA (including FMECA to support FDIR), sensitivity analyses, and formal RAMS reporting.</p></li></ul><p><strong>Skills and Requirements</strong></p><ul><li><p>10+ years of hands‑on experience in RAMS engineering for complex space systems, with direct responsibility for Reliability and Availability assessments.</p></li><li><p>Demonstrated experience on at least one space mission or flight‑critical program, where RAMS outputs directly influenced design decisions and risk acceptance.</p></li><li><p>Proven capability to build and quantify Fault Tree models and perform Reliability Allocation from system level down to critical items.</p></li><li><p>Solid experience performing FMECA at system and item level, including use of results to support FDIR and design mitigations.</p></li><li><p>Strong background in data gathering and data analysis for RAMS purposes, including use of reliability databases, assumptions management, and uncertainty handling.</p></li><li><p>Experience estimating service availability, including operational concepts, recovery strategies, and realistic MTTR assumptions.</p></li><li><p>Prior involvement in early‑phase RAMS activities (pre‑SRR / SRR), where incomplete data and evolving architectures are the norm.</p></li><li><p>Familiarity with Legacy &amp; NewSpace programs, where RAMS must be pragmatic, not bureaucratic.</p></li><li><p>Experience updating RAMS models to reflect design changes and optimization loops, not just producing static reports.</p></li><li><p>Exposure to sensitivity analysis and trade‑off studies used to guide architecture or redundancy decisions.</p></li></ul><p></p><p><strong>What does ReOrbit do?</strong></p><p>ReOrbit builds the foundation for the next generation of space applications by transforming satellites into truly intelligent, interconnected platforms, defined by software. Our satellite design philosophy revolves around the idea that satellites must network, communicate with each other and thus improve mission efficiency. How can this be achieved? Thanks to a flexible software-first architecture, where all these aspects are dealt with upfront in the mission concept, as integrated functionalities.</p><p>ReOrbit’s top-notch team of software engineers and system architects develop in-house software, procure hardware from the best-in-class suppliers, and seamlessly integrate the components to create flexible and secure satellites.
