SES Space & Defense operates as a government-focused satellite and connectivity provider with a 51–200-person footprint anchored in Reston. The hiring mix skews heavily toward senior engineering (8 roles) and director-level leadership (3), paired with concurrent infrastructure and program-management work—a pattern consistent with mission-critical aerospace contracts that demand both deep technical bench strength and formal governance structures. The active project list centers on multi-orbit architecture, payload systems integration, and earned-value program tracking, with documented pain points around cross-functional coordination and technical risk mitigation in complex, cost-constrained government programs.
Notable leadership hires: Chief Engineer, PMO Director
SES Space & Defense delivers integrated satellite and SATCOM solutions to government customers, with a focus on resilient, mission-critical capabilities across multiple orbits. The company operates through a portfolio of hosted payload services, managed SATCOM, and end-to-end bandwidth solutions designed for aerospace and defense applications. Core operational activities include mission-critical program execution (aerospace satellite program, multi-orbit architecture development), financial and earned-value management (EVM tracking, budget constraints), and integration across distributed stakeholder teams. Compliance and government audit support are embedded operational requirements. The company was founded in 1973 and operates as a public entity.
SES runs SATCOM and VSAT infrastructure alongside JavaScript/TypeScript web frameworks (React, Angular, Node.js), AWS SES, Salesforce, Docker/Kubernetes, and aerospace-specific tools: Remedy IT Service Management, Codebeamer, SysML, and SolarWinds for network operations.
Active initiatives include a multi-orbit architecture development, mission-critical aerospace satellite program, payload systems integration, government space-situational-awareness (SSA) mission integration, earned-value and financial program management, and process improvements for reporting and audit compliance.
