Senior System Quality Engineer

Systems Quality Engineer

The once-in-a-century transition to autonomous and electric vehicles is underway and will require a multi-trillion-dollar investment in energy and charging infrastructure, and the real estate to site it on. Terawatt is the leader in delivering large-scale, turnkey charging solutions for companies rapidly deploying AV and EV fleets. Whether it's an urban mobility hub or a carefully located multi-fleet hub for semi-trucks, Terawatt brings the talent, capabilities, and capital to create reliable, cost-effective solutions for customers on the leading edge of the transition to the next generation of transport.

With a growing portfolio of sites across the US in urban hubs and along key logistics and transportation corridors and logistics hubs, Terawatt is building the permanent transportation and logistics infrastructure of tomorrow through a robust combination of capital, real estate, development, and site operations solutions. The company develops, finances, owns, and operates charging solutions that take the cost and complexity out of electrifying fleets.

At Terawatt, we execute humbly and with urgency to provide tailored solutions for fleets that delight our clients and support the transition of transportation.

Our Technology

Terawatt is not a traditional infrastructure operator. Our technology platform transforms a portfolio of sites into a reliable, intelligent network — through advanced power management, operational optimization, and data-driven systems that back our customers with hard performance guarantees. That's what makes us a de-risked operator and a category-defining company.

We sit at a rare intersection: software, hardware, real estate, energy systems, and live site operations. The work is concrete and the stakes are real. The code you write today runs physical infrastructure tomorrow. You'll build systems that orchestrate megawatts of power across hundreds of chargers, ingest millions of telemetry events per day, and keep autonomous fleets, rideshare vehicles, and heavy-duty trucks moving — in real time.

Role Description

As a member of the Terawatt technology team in the role of Systems Quality Engineer you will own the processes and data that keep our charging systems performing to spec: defining what "good" looks like, measuring against it, and driving the engineering and operations teams to close the gap when it doesn't. You will be responsible for validating the quality and performance of our full stack products, from End-to-End electrical hardware and software interactions, with a focus on high-power EV charging solutions and energy management systems.

This role sits inside the technical organization with strong ties to field operations, software, and hardware procurement.

Core Responsibilities

• Define and maintain quality standards for Terawatt's charging systems, uptime thresholds, fault rates, charge session success rates, hardware failure modes, and build the measurement infrastructure to track them
• Contribute to a product-driven engineering culture that champions diverse ideas and bottom-up innovation
• Analyze field performance data to identify systemic failures, distinguish one-off events from recurring defect patterns, and prioritize engineering response accordingly
• Develop and implement comprehensive QA testing standards, specifically focused on OCPP and ISO 15118 communication protocols and system logs
• Triage and perform advanced root cause analysis on product or system issues, using network analysis tools like Wireshark and .pcap files to debug vehicle-to-charger communication and complex field failures
• Collaborate closely with vendors to manage and support resolution of critical firmware, hardware, and integration defects, ensuring alignment with technical specifications and SLAs for timely delivery and reliable operation of new features
• Ensure lab-to-site validation consistency by verifying that lab configurations and units exactly match field deployments to mitigate risks of unforeseen operational differences
• Develop and maintain inspection protocols for new site commissioning; ensure sites are handed off to operations meeting defined quality gates
