5G/LTE Network Engineer I

Parallelwireless; Boston (MA); On-site; USD 65,000 - 100,000; Full time

Job summary

Parallel Wireless is seeking a technically driven engineer to own the full lifecycle of mobile network infrastructure, from lab integration to live deployment and optimization.

You will trace signaling failures, investigate KPI-driven performance gaps, and develop tooling in Python/Bash to streamline data collection and reporting. This hands-on role requires independent thinking and rapid growth, with opportunities to work across RAN and core elements.

Qualifications

• Bachelor’s or Master’s degree in Telecommunications, Electrical Engineering, or related field.
• Authorized to work in the U.S. without sponsorship.
• Theoretical LTE/5G RAN and core network knowledge.
• Comfort with Linux command line environment.
• Basic scripting in Python or Bash.
• Ability to read and interpret packet captures.
• Analytical mindset with data-driven approach.
• Strong written and verbal communication.
• Willingness to travel internationally.

Responsibilities

• Deploy, configure, and commission LTE eNodeBs with 3rd party EPC and 5G core elements in lab and live environments.
• Perform end-to-end system integration and interface testing across S1, X2, N1, N2, N3.
• Analyze protocol traces (S1AP, NGAP, X2AP, E2AP, GTP-U, DIAMETER, SCTP) to diagnose issues.
• Monitor and troubleshoot KPIs for accessibility, retainability, mobility, availability, and performance; own root-cause analysis.
• Operate and maintain network performance management systems across multi-vendor environments.
• Support customer-facing lab trials and network acceptance testing with operator teams.
• Develop Python and Bash scripts to automate data collection, processing, and reporting.
• Write and maintain network topology diagrams, test plans, procedures, and post-mortems.
• Contribute to next-gen monitoring, including AI/ML anomaly detection and alerting.
• Stay current on 3GPP specs and evolving 5G standards; read specs thoroughly.

Job description

You will work across the full lifecycle of mobile network infrastructure from lab integration and commissioning through live deployment, performance monitoring, and ongoing optimization. One day you're tracing a signaling failure at the protocol level; the next you're investigating why a cluster of cells is underperforming against their KPI targets. This is a hands‑on, technically demanding role with no shortage of variety. You'll be expected to think independently, dig hard when you're stuck, and grow quickly. If you're the kind of person who reads beyond the syllabus and finds mobile networks genuinely fascinating rather than just academically interesting, you'll fit right in.

This role is based out of our Head Quarters office in Nashua, NH, 45 miles north of Boston.

Responsibilities

• Deploy, configure, and commission LTE eNodeBs to work with 3 party EPC components (MME, SGW, PGW), and 5G NR/Core elements in lab and live customer environments
• Perform end‑to‑end system integration and interface testing across S1, X2, N1, N2, and N3 reference points
• Analyze protocol traces (S1AP, NGAP, X2AP, E2AP, GTP‑U, DIAMETER, SCTP) to diagnose signaling failures, handover issues, and connectivity anomalies
• Monitor and troubleshoot RAN and core KPIs for accessibility, retainability, mobility, availability and performance and own root‑cause analysis when they degrade
• Operate and maintain network performance management systems, identifying trends and anomalies across multi‑vendor environments before they become customer‑impacting events
• Support customer‑facing lab trials and network acceptance testing, including direct engagement with operator engineering teams
• Develop scripts and tooling in Python and Bash to automate data collection, processing, and reporting workflows
• Write and maintain technically rigorous documentation: network topology diagrams, test plans, commissioning procedures, and incident post‑mortems
• Contribute to the integration of next‑generation monitoring capabilities, including AI/ML‑driven anomaly detection and intelligent alerting, into operational platforms
• Stay current on 3GPP specifications, GSMA guidelines, and evolving 5G standards; you'll be expected to read specs, not just summaries of them

Qualifications

• A Bachelor’s or Master’s degree in Telecommunications, Electrical Engineering, Computer Networks, or a related field, recent graduate or up to 1 year of experience
• Be authorized to work in the U.S. without sponsorship
• Theoretical foundation in LTE/5G RAN and core network architecture
• Comfort working in Linux environments from the command line
• Basic scripting ability in Python or Bash
• Ability to read and interpret packet captures even if you're still building that skill
• Analytical mindset: you approach a problem by forming a hypothesis and testing it systematically
• An appetite for data: you find patterns in large datasets interesting, not overwhelming
• Clear written and verbal communication: your analysis is only as good as your ability to explain it
• Ability to travel internationally as needed
