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.
