Software Engineer (C / C++ / Python) – SDK & Simulation

Spacebackend revolutionizes system integration in the aerospace industry through AI-driven interoperability across various hardware components. Our product, Lynapse, streamlines the satellite integration workflow by enabling modular integration across payloads, subsystems, and COTS. Our core technology transforms hardware specifications into digital twins and automatically generates, tests, and validates hardware-agnostic and OS-agnostic on-board satellite middleware.

As a C/C++/Python Software Engineer, you will architect and build end-to-end solutions for our core infrastructure - the Lynapse SDK. You will be responsible for developing a high-level framework that translates digital models (derived from hardware interface specifications) into functional, high-performance middleware and drivers. Your role is critical in bridging AI-driven design with reliable execution on diverse hardware targets, ensuring all generated components are rigorously validated through a custom simulation-based framework.

System Architecture & Roadmap

1. Define and evolve the SDK software architecture spanning on-board middleware, hardware simulation frameworks, and engineering tooling.
2. Own the SDK roadmap: prioritize features, set milestones, and align technical plans with business objectives.
3. Design and architect interfaces between AI/ML models and application infrastructure, including APIs and data pipelines.
4. Write technical documentation including PDR, CDR, product requirements, and solution architecture.

Hands-On Development & Simulation

1. Implement core modules in C/C++ and Python, ensuring high performance, reliability, and maintainability.
2. Develop and maintain a simulation-based framework to test and validate generated middleware and driver components.
3. Architect and develop the SDK/API for integration of core technology into 3rd party products and mission-critical workflows.

Infrastructure & Best Practices

1. Establish DevOps pipelines (CI/CD, automated testing, container orchestration) across cloud and on-prem environments.
2. Promote design patterns, coding standards, and architecture reviews to ensure scalable, modular solutions.
3. Involved in mentoring, roadmap planning, and coordination of R&D across product phases.
