Sr. Software Engineer, Command & Control

Responsibilities

• Develop backend Command & Control software connecting Quindar’s platform to satellite vehicles.
• Implement reliable machine-to-machine communications involving binary protocols, command and telemetry definitions, data transport, serialization, encoding, stateful communication, and hardware interfaces.
• Onboard new satellite vehicles by translating spacecraft-specific interfaces and protocols into maintainable platform integrations.
• Develop abstractions, tooling, and architecture that support many spacecraft without requiring every integration to be built from scratch.
• Design systems that scale across diverse vehicles, protocols, missions, and operational constraints.
• Troubleshoot and drive technically ambiguous integration problems through completion while communicating complex technical information to internal and customer-facing audiences.

Requirements

• Bachelor’s degree in Computer Science, Electrical Engineering, Computer Engineering, or a related technical field, or equivalent practical experience.
• At least three years of professional experience developing software for satellite C2 or comparable complex machine-to-machine and hardware/software systems.
• Proficiency in backend or systems programming languages such as Python and Rust.
• Experience communicating with, controlling, or processing data from remote machines, embedded systems, hardware assets, or other complex systems.
• Experience implementing or integrating machine-to-machine communication protocols and concepts including binary serialization, framing, packetization, transport, routing, sequencing, acknowledgements, error handling, and state management.
• Experience taking a protocol, interface specification, or hardware integration from documentation through implementation, testing, troubleshooting, and production operation.
• Experience with real-time or embedded software, distributed systems, networking, telecommunications, robotics, IoT, industrial systems, or hardware/software integration.
• Understanding of reliable communication with remote or intermittently connected systems, including bandwidth constraints, latency, retries, fault handling, and observability.
• Experience with relational and/or time-series databases and familiarity with Git and GitHub or similar version-control workflows.
• Preferred familiarity with CCSDS, CSP, CFDP, IP, XTCE, and MIB or comparable communication standards, schemas, interface definitions, and data models.
• Experience integrating AES-256 GCM, AES-256 CFB, AES-256 ECB, NSA Type 1 PEGASUS, or NSA Type 1 CARIBOU encryption algorithms is a plus.
• Experience with Kubernetes platforms, DevSecOps practices, and open-source software is preferred or a plus.
• Strong technical analysis, systems thinking, troubleshooting, adaptability, ownership, maintainability focus, cross-functional communication, and willingness to learn the aerospace domain.

Benefits

• Hybrid work arrangement with two days per week in the Arvada, Colorado, Washington, D.C., or Seattle, Washington office, with significant remote work.
