The role supports Environmental Monitoring capabilities within a broader space-based sensing enterprise and helps align technical baselines, requirements, interfaces, and mission outcomes across programs at different lifecycle stages., * Provide senior level systems engineering support to the Environmental Monitoring mission area. * Provide systems engineering and mission engineering support across the full lifecycle, including concept definition, requirements development, architecture assessment, integration planning, verification, transition, and sustainment. * Support technical baseline assessments for inherited or existing programs, including review of requirements, architecture products, interface documentation, test artifacts, risk posture, and maturity against mission objectives. * Establish consistent technical governance across programs that may be at different lifecycle stages. * Support Define-Assess-Forecast-Build activities by identifying technical competencies, expertise gaps, program maturity, workforce needs, and scaling priorities. * Develop, refine, and manage mission-level requirements, system requirements, technical baselines, interface needs, and performance measures. * Coordinate across government program leadership, PD/PO teams, acquisition stakeholders, technical SMEs, contractors, ground systems teams, mission users, and enterprise-level engineering leadership. * Support mission thread development, requirements traceability, operational use-case definition, and transition from mission need to executable engineering and acquisition plans. * Advise customer leadership on technical risk, requirements quality, architecture maturity, program readiness, integration gaps, and mission-area governance. * Support acquisition engineering activities, including technical input to acquisition strategies, RFPs, SOWs/PWSs, evaluation criteria, technical reviews, CDRLs, and contractor oversight. * Ensure Environmental Monitoring capabilities align with SBST lines of effort, enterprise standards, digital-engineering objectives, and progression toward IOC and FOC. * Use digital engineering, MBSE, architecture frameworks, model-based methods, or model repositories where useful to improve traceability, integration, analysis, and decision quality; tailor the approach to mission and program needs rather than treating tools as the objective. * Translate complex technical and mission needs into clear decision materials, executive briefings, engineering recommendations, and customer-facing guidance. ## Related Videos - [From Messy Queries to Scalable Systems - How Data Engineering actually works](https://www.wearedevelopers.com/videos/100203-from-messy-queries-to-scalable-systems-how-data-engineering-actually-works) - [Robots are coming into the wild!
