About the role

  • Own configuration management for mission-system products: maintain authoritative configuration baselines for airborne software, mission systems, autonomy services, ground-segment components, simulation adapters, data schemas, OMS/UCI catalogs, and Mission Data Load (MDL) formats; ensure these baselines serve as complete, release-ready product artifacts.
  • Manage the aircraft and mission-system ICDs: own the creation, publication, and maintenance of Interface Control Documents (ICDs), ensuring consistency across all message schemas, service definitions, timing semantics, field encodings, and API mappings; maintain these artifacts as formal product deliverables with structured version control.
  • Develop, maintain, and validate SysML models in Cameo: create and update SysML block diagrams, sequence diagrams, activity models, interface definitions, ICD mappings, and behavioral models in Cameo to reflect the evolving system architecture; ensure Cameo models remain authoritative and synchronized with ICDs, schemas, and product baselines.
  • Implement automated ICD, OMS, and UCI conformance processes: develop and operate schema-validation tools, message diff utilities, field-level comparison tools, and automated interface conformance harnesses; enforce OMS/UCI compliance and detect regressions before integration or release.
  • Run change-control workflows and publish productized artifacts: chair or coordinate Change Control Board (CCB) processes, assess technical impacts, track decisions, and publish updated ICD versions, schema sets, SysML model updates, and configuration packages; ensure all changes result in high-quality, auditable product outputs.
  • Maintain configuration status accounting (CSA): track as-designed, as-built, and as-flown configurations across hardware, software, autonomy behaviors, OMS/UCI service catalogs, simulation models, and mission data formats; ensure that CSA records are product-level deliverables supporting test readiness, reviews, and audit traceability.
  • Integrate configuration practices with version-control tools: manage repositories, tagging structures, and metadata used to track ICD revisions, OMS/UCI schemas, SysML model versions, and software component baselines; ensure complete traceability from requirements to models to interfaces to releases.
  • Support integration, simulation, and test teams: ensure SITL, HITL, and real-flight test environments use correct interface definitions, service catalogs, schema versions, and SysML model interpretations; manage and resolve interface inconsistencies discovered during testing.
  • Generate end-product deliverables for internal and external customers: produce high-quality ICDs, configuration baselines, SysML model packages, schema repositories, conformance reports, data packages, and configuration audit artifacts that meet program requirements, support design reviews, and satisfy customer expectations for completeness and traceability.
  • Communicate product baseline health and interface status: report configuration risks, ICD changes, incompatibilities, SysML model updates, and release readiness to the Lead Systems Integration Engineer, Product Engineering Lead, and program leadership; ensure all stakeholders understand baseline impacts.

Requirements

  • Bachelor’s or Master’s degree in Systems Engineering, Software Engineering, Aerospace Engineering, Computer Engineering, or a related technical discipline.
  • 6+ years of experience in configuration management, interface governance, mission system integration, or software configuration control for aerospace or distributed systems.
  • Strong hands-on experience with Cameo and SysML, including authoring interface models, sequence diagrams, activity diagrams, block diagrams, and ICD-to-SysML mappings.
  • Demonstrated expertise working with Interface Control Documents (ICDs), Open Mission Systems (OMS) schemas, Universal Command and Control Interface (UCI) service definitions, and message catalogs.
  • Experience developing or operating schema validators, API test harnesses, protocol analyzers, and automated conformance tools.
  • Proficiency with version-control systems such as Git, including tagging, branching, and traceability practices aligned with configuration status accounting.
  • Experience running or contributing to Change Control Boards (CCBs), configuration audits, Functional and Physical Configuration Audits (FCA/PCA), and release governance.
  • Familiarity with Software-in-the-Loop (SITL), Hardware-in-the-Loop (HITL), and simulation environments, and how interface changes propagate across these ecosystems.
  • Ability to interpret and troubleshoot service models, API definitions, schemas, state machines, message structures, and timing semantics.
  • Strong communication and organizational skills with the ability to coordinate across autonomy, mission systems, ground systems, avionics, and test teams.
  • Ability to deliver polished, complete, customer-ready product artifacts on schedule.
  • Active Secret clearance required; Top Secret / Sensitive Compartmented Information (TS/SCI) preferred.
