Parallel Wireless is reimagining mobile networks with innovative, energy-efficient Open RAN solutions. We are now embedding agentic AI deep into our engineering lifecycle — from feature development to field debugging — to accelerate delivery and raise quality across our 4G/5G stack.

Role Summary

We’re looking for a hands-on QA-Dev Engineer / Technical Lead to help redefine how Open RAN software is built and validated — by putting agentic AI at the center of our engineering workflow.

You’ll design and run the agent-driven systems that handle the time-intensive parts of RAN engineering: agents that author test plans and scripts against 3GPP specifications, execute 4G/5G test campaigns and continuously monitor lab setups, triage logs and perform root-cause analysis when failures arise, and generate PRVT builds to validate proposed fixes — all at a scale humans alone can’t sustain.

What you bring is deep RAN expertise — protocol stack, call flows, end-to-end systems — paired with strong judgment for what AI agents can and cannot be trusted to do. The result: faster fix cycles, broader test coverage, and engineers freed to focus on the hard, novel problems.

What you'll do: AI-Augmented Engineering

Use agentic AI to author test plans for 4G/5G features aligned with 3GPP specifications, and to generate, refactor, and maintain test scripts in the in-house automation framework

Design and build end-to-end test setups, including RF setups, that are agent-observable and agent-controllable

Orchestrate agents to execute regression and feature test suites, triage failures, classify them (product bug / setup issue / flake), and file/update tickets in JIRA with full evidence

Build agent workflows that continuously monitor test setups (lab health, UE state, simulator status, RF chain), detect anomalies, and self-heal or escalate

Drive RCT (Regression / Continuous Testing) automation as an AI-driven pipeline rather than a static script suite

Drive AI-assisted log analysis and use agentic workflows to perform root-cause analysis on field and lab issues — across simulators, vBBU components, and end-to-end systems — tuning prompts, tools, and retrieval pipelines for accuracy on RAN-specific data

Trigger and supervise agent-generated PRVT builds that compile, package, and deploy fix candidates to validation setups automatically

Verify Parallel Wireless products for functional, stability, performance, and user-experience aspects, with AI in the loop

Review code (human-written and agent-written) for correctness, maintainability, and performance; contribute to design documents and architecture discussions

Technical Leadership & Collaboration

Mentor the QA-Dev team on agentic patterns, prompt engineering, tool integration, and evaluation of AI workflows for engineering tasks

Define guardrails, eval harnesses, and quality metrics for agent outputs (RCA accuracy, fix-validity rate, test-coverage uplift, false-positive rate on monitoring)

Collaborate cross-functionally with:

FQG and RQG QA teams for feature verification and test planning

PHY and Platform teams for integration and performance tuning

PLM and System Architecture for product and architectural alignment

Support customer deployments with expert-level (AI-assisted) troubleshooting

Drive continuous improvement in tools, agent capabilities, and engineering processes

What you must have: Experience

Bachelor’s or Master’s (B.E./B.Tech. or M.E./M.Tech.) in Electronics, Communication, Computer Science, Electrical Engineering, or equivalent

8-12+ years in telecom software development and/or QA, with at least 3 years in a technical leadership role

Hands-on experience in RAN development and/or testing

Core Technical Skills

Deep understanding of LTE / LTE-A protocol stack and Open RAN architecture; strong grasp of 4G/5G call flows

Thorough knowledge of 3GPP standards covering PHY, MAC, RLC, PDCP, RRC, S1AP, and X2AP protocols

Strong programming in C/C++ and scripting in Python and Bash/Shell

Solid working knowledge of LAN/WAN, WLAN, L2/L3 routing, TCP/IP, and QoS

Proficiency on Linux/UNIX platforms

Experience handling and troubleshooting User Equipment (mobiles)

Experience with virtualization and vRAN deployment models

Experience with test management and bug-tracking tools (e.g., JIRA)

AI / Agentic Skills (Required for this role)

Practical experience using LLM-based coding and reasoning agents (e.g., Claude Code, Cursor, Copilot agents, or equivalent) for real engineering work — not just demos

Understanding of agentic patterns: tool use, multi-step planning, retrieval over logs/specs/code, evaluation loops, and human-in-the-loop gating

Ability to design, prompt, and debug agent workflows that operate on large RAN log sets, source repos, and CI/CD pipelines

Comfort integrating agents with internal systems — CI/build systems, log stores, JIRA, lab controllers, test runners

Soft Skills

Excellent communication, leadership, and problem-solving skills

High judgement on when to trust, verify, or override AI output — especially on safety- and customer-impacting fixes

Strong cross-functional collaboration in agile environments

Added Advantage / Preferred

Experience with 5G NR stack and O-RAN specifications

Familiarity with Docker, Kubernetes, OpenStack and cloud-native pipelines

Knowledge of RF signal tests/analysis and hands-on with Signal Analyzers, Signal Generators, Oscilloscopes

Experience building eval frameworks for LLM/agent outputs in production engineering settings

Prior experience in customer-facing or support-engineering roles

Education:

Bachelor’s (B.E/B.Tech) or Master’s degree (M.E. or M.Tech.) in Electronics/Communication/Computer Science Engineering or equivalent training, education and experience
