Chief Architect & Enterprise - Space- Sensing & Tracking, Environmental Monitoring

Overview

Stellar Solutions, a nationally recognized “Great Place To Work,” delivers engineering solutions across commercial space and national security missions—from innovative new entrants to established space systems organizations.

We bring talented, energetic, and immediately productive professionals to meet critical customer needs in systems engineering and integration, mission operations, program management, and strategic planning—helping teams deliver resilient capability to the mission with speed, quality, and focus.

Stellar Solutions is seeking a Chief Architect & Enterprise Support professional to provide senior enterprise architecture, front‑office advisory, cross‑program integration, technical strategy, and program‑support leadership for a proposed government space systems and mission‑support effort. The role supports customers standing up, inheriting, and scaling complex space, ground, data, and mission capabilities.

The position is designed for a trusted senior leader who can help customer executives and program offices frame the problem, shape technical and programmatic options, connect programs at different stages of maturity, and drive coordinated action across government, contractors, mission partners, and operational users. Digital engineering, MBSE, and model‑based methods are valuable capabilities within the role, but the primary purpose is broader enterprise architecture and front‑office support: turning mission priorities into coherent technical strategy, executable plans, and decision‑quality recommendations.

This is an enterprise‑support and chief‑architect role for a highly experienced systems, mission, or program leader who can operate above a single program while still engaging deeply enough to resolve technical, integration, execution, and stakeholder issues. The role may also perform contract program‑management or task‑lead duties for Stellar, as appropriate, while supporting the Government in aligning architecture, requirements, schedules, risks, acquisition activities, and mission outcomes across a complex portfolio.

• Serve as a senior enterprise architect and front‑office advisor supporting complex space systems, mission‑support, and related national security mission areas.
• Advise senior government leadership on portfolio‑level technical strategy, architecture direction, cross‑program dependencies, capability gaps, risk posture, and priorities for future development.
• Help define and mature enterprise architecture approaches that connect mission needs, operational effects, requirements, space and ground segments, data flows, interfaces, processing, dissemination, and end‑user outcomes.
• Provide cross‑program integration support for efforts at varying stages of maturity, helping establish common technical direction, governance rhythms, decision forums, and integration mechanisms.
• Assess existing and emerging programs for architecture consistency, technical maturity, interface risk, execution dependencies, requirements gaps, and opportunities for reuse or harmonization.
• Lead or support enterprise‑level architecture trades, mission threads, operational use cases, effects‑chain analysis, and capability roadmaps that inform customer decisions and acquisition priorities.
• Coordinate across program offices, mission systems engineers, acquisition organizations, contractors, FFRDCs, advisory teams, ground‑system teams, data and mission users, and senior customer stakeholders.
• Help customer leadership translate strategic mission objectives into actionable architecture, requirements, acquisition, integration, and operational‑transition plans.
• Provide technical and programmatic input to front‑office planning, executive briefings, investment decisions, staffing and competency assessments, program reviews, and enterprise roadmaps.
• Support acquisition and contractor oversight activities by contributing to technical strategy, RFP and SOW/PWS inputs, evaluation criteria, CDRLs, technical‑review expectations, architecture deliverables, and execution governance.
• Use digital engineering, MBSE, architecture frameworks, model‑based methods,…
