Network Software Developer

**Network Software Developer** *Integrated Switching Technologies Ltd. \| Remote \| Part\-Time \| Temporary* At IST we're building intelligent networking infrastructure for environments where failure isn't an option. We're small, we move fast, and we care deeply about the technical depth of our work. If you want to own problems end to end and build something that matters, read on. We're an early\-stage startup building mesh networking infrastructure for contested, dynamic environments — satellites, drones, tactical communications. We don't build things that have been built before. This is not a maintenance role. It's an opportunity for engineers who want to own hard problems end to end and have direct influence on product direction. If you're adaptable, collaborative, and energized by the challenge of building something from the ground up alongside a small, highly motivated team, we want to hear from you. **About the Role** You'll be a core contributor to IST's mesh state synchronization software — a distributed bundle propagation system designed to operate in dynamic, contested network environments including satellite constellations, drone swarms, and tactical radio networks. This is systems\-level Python work at the protocol layer, not application development. You'll be working directly with IST's founder and a research partner at Colorado School of Mines. Qualifications Required: * Python (strong, systems\-level — not web/scripting) * Distributed systems design and implementation * Network socket programming (TCP/UDP, raw sockets) * Concurrent and async programming (asyncio, threading, multiprocessing) * Message passing and inter\-process communication * Protocol design and implementation experience * Data serialization (Protocol Buffers, MessagePack, or similar) * Version control (Git) * 10\+ years software development experience **Desired:** * Delay\-tolerant networking (DTN) — ideally Bundle Protocol (RFC 5050/9171\) * P2P network architecture (BitTorrent, Kademlia, or similar) * MANET or mesh network protocol experience * Software\-defined networking concepts * Link\-state or distance\-vector routing protocol internals * Experience with challenged/contested network environments * Rust or C\+\+ (relevant for Phase II production implementation) * Linux systems programming * Prior DoD, aerospace, or defense software experience * Familiarity with government software development practices INTEGRATED SWITCHING TECHNOLOGIES LTD.
