Job description

About Terawatt Infrastructure

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. 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.

Our Values

Six core values guide how we work: commitments we make to each other. Our pace is set by a simple conviction: imperfect action beats perfect inaction, so we move with purpose, adapt without ego, and measure ourselves by progress rather than activity. Ownership travels with autonomy. Your name is on the work, and the best answer wins the conversation, wherever it lives. That candor works because of what surrounds it: people who show up with intention and have each other's back, tough on ideas and generous with people. Our customers feel this as reliability earned daily, every interaction treated as a chance to build something lasting. And underneath it all is why the work matters. The climate doesn't wait, and the stakes are also human: behind every checklist and every inspection is a person going home safely. We call it "This work has a heartbeat” — it's what the other five rest on.

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

You are enthusiastic about joining a transformative organization that sits at the intersection of climate impact, electric vehicle charging infrastructure, exceptional customer experiences, and technological innovation in a rapidly evolving industry.

Your commitment to quality and to customer‑centric products will shape how our solutions meet the specific needs of our customers, while upholding the reliability that is synonymous with the Terawatt brand.

This role is built for a QA automation specialist who treats test infrastructure as a first‑class engineering problem: someone equally comfortable designing test coverage and building the CI/CD pipelines, containerized environments, and orchestration that run it. You’re also curious about where AI‑assisted tooling — self‑healing test automation, LLM‑assisted test authoring, visual AI regression — can responsibly expand coverage and cut maintenance load, and be disciplined enough to validate that output rather than take it on faith.

You will own the framework for comprehensive testing, automation, and quality across our product ecosystem, working closely with a highly skilled software, hardware, and product development team and directly with our technology leadership.

Core Responsibilities

• Own and extend the test automation framework across UI, API, and hardware‑in‑the‑loop test surfaces, validating the larger design decisions with technology leadership, to enable high development velocity.
• Build and maintain the CI/CD test infrastructure — pipeline orchestration, containerized/ephemeral test environments, environment provisioning, and test parallelization — partnering with DevOps/SRE to keep it scalable, observable, and maintainable.
• Develop comprehensive test plans for software and hardware‑in‑the‑loop product features; identify test scenarios, cases, and test data to ensure coverage for new and existing features.
• Maintain test cases and scripts in the Test Management System; analyze test results to help developers address underlying issues.
• Monitor production bugs to identify root causes, expand test coverage to minimize escapes and provide reports on product quality metrics.
• Triage automation failures, identify gaps between existing tests and the automation framework, and implement solutions to keep the system reliable and performant.
• Design and execute performance and scale testing, security testing, and user experience testing as requirements demand.
• Evaluate, pilot, and introduce AI‑assisted testing tools — e.g., self‑healing test automation, visual AI regression testing, LLM‑assisted test authoring — to increase coverage and cut maintenance overhead, while validating that their output actually meets Terawatt’s quality bar rather than accepting it uncritically.
• Provide technical leadership and mentorship to software engineers on best practices for building and enhancing test suites, fostering a culture of quality and continuous improvement.
• Collaborate with cross‑functional teams — Developers, SREs, Product Managers, and Operations — to validate end‑to‑end functionality.

Minimum Qualifications

• Bachelor's degree or above in Computer Science, Electrical Engineering, or a related field.
• 7+ years of experience in a Quality Assurance role, delivering high‑quality, reliable products to market.
• 4+ years of demonstrable experience designing automation frameworks and developing test automation software and tools.
• Demonstrable experience leading QA projects and initiatives.
• Working knowledge of test methodologies, processes, and tools such as Playwright, Cypress, Selenium, Appium, JIRA, STLC, and test management tools like TestRail, ALM, or Zephyr; and automation frameworks or tools such as Karate, Requests, HttpRunner, TestNG, or Fiddler.
• Hands‑on experience designing, building, and maintaining CI/CD pipelines‑as‑code (e.g., GitHub Actions) — not just consuming pipelines someone else built.
• Experience containerizing test environments (Docker required; Kubernetes a plus) and provisioning episodic or on‑demand test infrastructure.
• Coding skills: proficiency in Python required; shell scripting for pipeline and infrastructure tooling is a plus.
• Strong analytical and troubleshooting skills, technical aptitude, attention to detail; self‑motivated and quick to learn new concepts, technologies, and products.
• Excellent communication and interpersonal skills; highly detail‑oriented.

Preferred Qualifications

• Familiarity with Infrastructure‑as‑Code (e.g., Terraform, Ansible, or similar) for building reproducible test environments.
• Familiarity with performance, security, and accessibility testing.
• Familiarity with ETL testing, data quality frameworks, and advanced SQL is a plus.
• A plus: hands‑on curiosity with AI‑assisted QA tooling — self‑healing locators, visual AI regression testing, or using LLMs to help generate and maintain test scripts and test data.
