Senior Software Engineer, Backend Systems

The role

You will design and build backend services that ingest spectrum data, orchestrate ML inference, and power autonomous agents. You will set technical direction, make architecture decisions, and mentor engineers.

What you will do

• Design, build, and operate reliable, scalable backend services.
• Architect the agent layer including tool-calling, orchestration, state management, memory, and evaluation harnesses.
• Own the ML inference architecture including model serving, scheduling, and latency optimization.
• Define service boundaries, data contracts, and API standards.
• Build for production with instrumentation, alerting, and runbooks.
• Partner with ML researchers to move models from experiment to production.
• Lead design reviews and mentor engineers.

Required qualifications

• 4–6+ years of professional software engineering experience building and running backend / distributed systems in production.
• Strong proficiency in at least one of Python, Go, Rust, or a similar systems-capable language.
• Hands-on experience with AWS or another major cloud provider (GCP, Azure).
• Experience building or integrating LLM / agent systems.
• Experience serving ML models in production.
• Deep understanding of APIs (REST / gRPC), async processing, message queues / streaming, and data consistency trade-offs.
• Track record of owning systems end to end and making architecture decisions.

Nice to have

• Experience with containers and orchestration (Docker, Kubernetes, ECS).
