About Plug
Plug is the marketplace for used electric vehicles. Consumers get an instant cash offer backed by battery-health data, and dealers across the US bid in real time on that inventory. Former Tesla executives founded Plug in 2023. We’ve facilitated $150M in EV sales and raised a $20M Series A led by Lightspeed Venture Partners.

Why Plug

• You’ll own a piece of the biggest infrastructure opportunity in automotive.

• You’ll work on a platform built exclusively for EVs, with nothing adapted from legacy automotive.

• You’ll be part of an AI-native company. We’re rethinking how work gets done at a fundamental level.

• You’ll work directly with operators who have scaled multi-billion dollar businesses in automotive, EV, and marketplaces.

• You’ll have real ownership, high autonomy, and a direct line to company outcomes.

The Opportunity
We are looking for a Senior Engineer to join our growing team. A senior full-stack software engineer, you’ll report to our Head of Engineering and own entire customer-facing or internal products. We’re building systems like AI-powered pricing intelligence, real-time connectivity to vehicle manufacturer APIs, auction applications, and data pipelines that aggregate EV-specific information from dozens of sources, all to make the wholesale EV market faster, smarter, and more transparent.

As a member of the team, you’ll help lay the technical and product foundation for our growing business. We’re building a culture that cares about collaboration, encourages intellectual honesty, celebrates technical excellence, and is driven by careful attention to detail and planning for the future. We believe diversity of perspective and experience are key to building great technology and a thriving team. Sounds cool? Let’s work together.

What You’ll Do

• Collaborate with colleagues and be a strong voice in product design sessions, architecture discussions, and code reviews.

• Design, implement, test, debug, and document work on new and existing software features and products, ensuring they meet business, quality, and operational needs.

• Take ownership of features and products, and support their planning and development by understanding the ultimate goal and evaluating effort, risk, and priority in an agile environment.

• Use agentic coding tools to write clear, efficient, and scalable code with an eye toward flexibility and maintainability.

• Own and contribute to team productivity and process improvements.

• Use and develop APIs to create integrations between Plug and third-party platforms.

• Actively raise the technical bar of the team through thoughtful code review, pairing, and knowledge sharing, including how you use AI tools.

• Be an integral part of a close team of developers. This is an opportunity to help shape a nascent team culture. The ideal candidate is a high-growth individual able to grow their career as the team grows.

What You’ll Bring

• 5-8 years of hands-on experience developing and delivering production applications.

• Demonstrated proficiency in TypeScript across the full stack: backend, frontend, relational databases, and API and webhook integrations. Temporal experience is a strong plus.

• Hands-on experience deploying and operating cloud-hosted applications. Comfort with infrastructure-as-code (we use Terraform), CI/CD pipelines, feature flags, and observability tooling.

• Experience in agent-first development workflows: comfortable orchestrating multiple agents, defining clear acceptance criteria, and reviewing AI-generated output with a high quality bar.

• A strong engineering quality bar: writing tests, conducting code reviews, producing code that is readable by both humans and AI agents, and communicating clearly in writing.

• Considers cross-surface and downstream implications of technical decisions. Writes code and designs systems that other engineers can understand, extend, and depend on.

• Prior startup experience and a track record of owning work end to end: scoping, shipping, and measuring impact.

• Authorized to work in the US for any employer.

• Prior experience in automotive or EV systems is a plus.
