Senior Software Engineer, Backend Systems

Distributed Spectrum develops radio spectrum intelligence systems using radio data, neural networks, and specialized computing infrastructure. The Senior Backend Engineer will design and operate scalable backend services, architect agent-native platform capabilities, own ML inference architecture, and provide technical leadership through architecture decisions, design reviews, and mentorship.

Responsibilities:

• Design, build, and operate backend services that are reliable, observable, and built to scale with our sensor fleet and customer base
• Architect the agent layer of our platform: tool-calling interfaces, orchestration, state management, memory, and evaluation harnesses for LLM- and model-driven agents
• Own the ML inference architecture — model serving, batching, GPU/CPU scheduling, latency and cost optimization, and the APIs that expose inference to the rest of the system
• Define service boundaries, data contracts, and API standards across the backend
• Build for production: instrumentation, alerting, graceful degradation, and clear runbooks
• Partner closely with ML researchers to move models from experiment to production quickly and safely
• Lead design reviews, mentor engineers, and raise the bar on code quality and engineering practice
