Connectivity Solutions Architect - Cellular / Multi-Carrier Bonding (Los Angeles)

Parallel Systems is pioneering autonomous battery-electric rail vehicles designed to transform freight transportation by shifting portions of the $900 billion U.S. trucking industry onto rail. Our innovative technology offers cleaner, safer, and more efficient logistics solutions. Join our dynamic team and help shape a smarter, greener future for global freight.Connectivity Solutions Architect - Cellular / Multi-Carrier Bonding Parallel Systems designs and deploys mission-critical cellular connectivity for field-deployed assets that operate in environments where a single carrier will not suffice. We are seeking a Connectivity Solutions Architect who pairs deep, hands-on cellular networking expertise with established relationships across the major US network operators and who has personally delivered high-quality connectivity where others could not: remote sites, RF-dense venues, and moving vehicles. This is a hands-on role. You will architect, deploy, and maintain multi-carrier bonded connectivity solutions end to end, and act as the technical bridge between our field operations and our carrier partners. Key Responsibilities Architect and deliver multi-carrier network bonding solutions (link aggregation, WAN smoothing, hot failover) for field-deployed assets requiring sustained, high-quality connections. Own the full deployment lifecycle of field networking infrastructure: site survey, installation, commissioning, monitoring, and ongoing maintenance. Integrate and troubleshoot third-party cellular modems and routers, along with the VPN / WAN-smoothing / tunneling overlays that keep sessions alive across degraded links. Manage technical relationships with major US network operators (AT&T, Verizon, T-Mobile — including FirstNet, Frontline, and T-Priority programs): device certification, SIM/eSIM provisioning, data-plan structuring, and escalation. Diagnose and resolve connectivity failures in challenging RF conditions (remote, mobile, high-density), where signal quality, latency, jitter, and packet loss are the primary adversaries. Support cell-connected edge terminals and mobile/fleet vehicles, ensuring connection quality meets application requirements. What Success Looks Like: Within 30 days: You have conducted a full assessment of the existing connectivity solutions on Parallel’s vehicles/infrastructure and have created an immediate list of potential improvements, including changes to software and hardware configurations. You have drafted test plans to evaluate changes for improved connectivity. Within 60 days: You have conducted field tests in real-world conditions to prove out configuration changes to improve the speed, reliability, and coverage of existing connectivity solutions. You have designed and are implementing field-deployed infrastructure to extend coverage out of the commercial coverage area and are rolling those into your test plans. Within 90 days: You have deployed infrastructure out into active Parallel deployments and have proven its effectiveness in real-world conditions. You are making structural changes to the automated testing environments in the lab to replicate observed field conditions and close test coverage gaps in our connectivity suite. Basic Requirements: Demonstrated hands-on experience with cellular networking (4G/LTE and 5G) and with OEM multi-carrier bonding platforms (e.g., Peplink SpeedFusion, Dejero, LiveU, TVU Networks, Haivision). A verifiable track record of establishing reliable cellular connectivity in challenging, connectivity-hostile environments. Established working relationships and direct experience with the major US network operators. Career experience supporting cell-connected, field-deployed assets - edge terminals, mobile vehicles, or comparable remote units — with high connection-quality requirements. Hands-on experience with third-party modems and with VPN / WAN-smoothing technologies (forward error correction, packet duplication, adaptive routing, failover). Documented experience deploying and maintaining networking infrastructure in the field - not solely in a lab or data center. Preferred Requirements: Experience with live or low-latency video streaming over bonded cellular (adaptive bitrate encoding, H.264/HEVC, SRT/RTMP, contribution workflows). We are committed to providing fair and transparent compensation in accordance with applicable laws.
