Senior Technical Lead - Radio Intelligent Controller Systems

Parallel Wireless is reimagining mobile networks with innovative, energy-efficient Open RAN solutions. Join us as we lead the future of telecommunications, driving innovation through green and sustainable networks . Learn more about our mission, vision and values .

We're hiring a Senior Technical Lead to own, end-to-end, one of the most technically diverse systems in telecom software: a Near-RT RIC platform that ingests live radio-network telemetry and makes automated control decisions in well under one second, coordinated across 50+ interdependent microservices. You'll operate across the entire stack — from the SCTP/ASN.1 wire protocol that talks directly to the radio network, through a custom low-latency message bus routing thousands of messages between services, to the Redis-backed stateful data layer that keeps the whole system consistent under load. If you're equally comfortable in a C++ debugger chasing a race condition and in a system-design conversation about how 50 services should talk to each other, this is that role.

What You'll Do:

• Own the architecture and reliability of a distributed, real-time system spanning C, C++, and Go, where control decisions must complete end-to-end in well under one second.
• Work across the full stack of the platform: RAN-facing protocol termination (SCTP, ASN.1 PER-encoded E2AP), a custom high-throughput messaging layer, stateful in-memory data services (Redis), and the microservices built on top of them.
• Lead cross-cutting technical initiatives — protocol upgrades, major library and version migrations, and platform-wide reliability and performance work — across a system of 50+ interdependent services.
• Set architectural direction and technical standards for a fast-moving, multi-team codebase, and act as the escalation point when an issue crosses service boundaries.
• Review and guide design for the platform's most latency- and safety-critical components: message routing, subscription and state management, and RAN protocol handling.
• Mentor engineers across the stack, from systems-level C/C++ engineers to Go service developers.
  
  

What We're Looking For:

• 8+ years of professional software engineering experience, with deep, hands-on proficiency in C/C++ and Go.
• Real experience with low-latency, high-throughput distributed systems — message routing/queuing, stateful services, and correctness under concurrency at scale.
• Comfort working close to the metal: sockets, protocol encoding/decoding, performance profiling, and Linux systems-level debugging.
• Experience designing or operating systems built from dozens of independent, interacting microservices.
• A track record of leading complex, multi-team technical initiatives from design through production rollout.
  
  

Nice to Have:

• Experience with telecom or networking protocols (SCTP, ASN.1, or similar binary/wire protocols); O-RAN, 5G, or 4G RAN experience is a strong plus.
• Experience with Kubernetes-based deployment of network functions, and with Redis, Kafka, or comparable stateful/streaming infrastructure.
• Experience building or maintaining custom messaging or routing layers.
  
  

What We Offer:

• Ownership of one of the most technically diverse systems in telecom — sub-second real-time control, ML-driven automation, and everything in between.
• Direct influence over the architecture of a growing, open-standards-based platform.
