Software Engineer, Systems Engineer

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用lanning, 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.

Location: Huntsville, AL

Facility: On-Site

Security Clearance: Active TS Required

Travel: 30%

• 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

• Active Top Secret security clearance
• Bachelors or Masters 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

• Experience with systems like Orbit Logic, STK/ODTK tasking models, Free Flyer 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
