Summary
T2S Solutions is seeking a Software Engineer specializing in payload command and control, tasking workflows, and mission scheduling for advanced satellite systems. This role focuses on the software that manages payload operations�planning, optimizing, generating, validating, and dispatching payload tasking and command products across a multi-segment satellite architecture. The ideal candidate has experience with mission planning, automated scheduling, data-driven operations, and the integration of payload-specific constraints into operational software.

Responsibilities

• Design and implement payload tasking and command-generation software, including payload modes, timelines, and configuration state tracking
• Develop automated scheduling engines that incorporate orbital dynamics, payload constraints, resource limits, priority rules, environmental constraints, and partner-driven tasking inputs
• Build payload C2 services, APIs, and microservices that interface with spacecraft flight software, ground systems, mission planning tools, and external data consumers
• Integrate payload data workflows, including command generation, execution status, telemetry ingestion, and downstream processing triggers
• Work closely with systems engineers to define payload command schemas, operational constraints, timing models, and verification logic
• Collaborate with mission operations, data processing, and ground teams to ensure end-to-end payload readiness, from planning to product delivery
• Develop simulators and test harnesses to validate payload behaviors, timelines, and scheduling algorithms
• Support V&V activities, including interface testing, timeline validation, and participation in readiness reviews focused on payload operations
• Ensure software follows best practices for accuracy, reliability, observability, scalability, and security

Qualifications

• Ability to obtain and maintain a Top Secret security clearance
• Bachelor�s or Master�s degree in Computer Science, Software Engineering, Aerospace Engineering, or related technical field and 5+ years of software development experience, ideally involving mission-critical or real-time systems
• Direct experience with tasking, scheduling, or command/control software, particularly for payloads or mission systems
• Understanding of payload operations, resource modeling, timing constraints, and command definition
• Experience developing APIs, services, and distributed architectures for operations or data-driven workflows
• Familiarity with rule-based and algorithmic scheduling approaches, constraint modeling, or optimization frameworks
• Ability to work closely with multidisciplinary engineering teams and external partners

Preferred Qualifications

• Experience with systems like Orbit Logic, STK/ODTK tasking models, FreeFlyer mission planning, or custom mission scheduling engines
• Background in payload-intensive concepts
• Knowledge of constraint solvers, optimization libraries, or automated reasoning engines
• Experience designing or interpreting payload command dictionaries, schemas, or ICDs
• Familiarity with cloud-native architectures, container orchestration, and messaging frameworks
• Understanding of telemetry and data product workflows, including processing chains and mission data routing
• Experience with digital twins, simulation environments, or hardware-in-the-loop payload testing
