Sr. Full-Stack Software Engineer

Job Title: Sr. Full-Stack Engineer

Team: Engineering

Location: Onsite - Santa Monica, CA

Employment Type: Fulltime, Salary, Exempt

Reports To: Engineering Lead

Plug is an automotive fintech startup building the marketplace for electric vehicles. Consumers, dealers, and commercial partners trade in, sell, and auction used EVs through a platform built exclusively for electric, with nothing adapted from legacy automotive.

Consumers can get an instant cash offer in minutes, backed by data-driven pricing, battery state-of-health analysis, with pickup, payment, and title transfer handled end-to-end. Franchise and independent dealers across the United States bid in real time on inventory sourced directly from these consumers, dealers, and commercial partners. The result is a single platform that gives sellers a fast, fair exit and gives dealers a dedicated channel for sourcing used EV inventory.

Founded in 2023 and led by former Tesla executives, Plug has facilitated $100M in EV sales since launch and is backed by a $20M Series A from Lightspeed Venture Partners. We're building the most AI-native startup team in Los Angeles, full of operators, engineers, and ML researchers laying the transaction rails for the used EV market's exponential growth.

• 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.

We are looking for a Senior Engineer to join our growing team! A senior full-stack software engineer who will report to our engineering lead, and who will own entire customer-facing or internal products. We're building systems like AI-powered pricing intelligence, real-time connectivity to vehicle manufacturer APIs, auction application, 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.

• 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 towards flexibility and maintainability.

• Own and contribute to team productivity and process improvements.

• Use and develop APIs to create integrations between Plug and 3rd 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 will be a high-growth individual able to grow their career as the team grows.

• 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/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.

• Operates 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.
