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.\nWhy Plug\nYou’ll own a piece of the biggest infrastructure opportunity in automotive.\n\nYou’ll work on a platform built exclusively for EVs, with nothing adapted from legacy automotive.\n\nYou’ll be part of an AI-native company. We’re rethinking how work gets done at a fundamental level.\n\nYou’ll work directly with operators who have scaled multi-billion dollar businesses in automotive, EV, and marketplaces.\n\nYou’ll have real ownership, high autonomy, and a direct line to company outcomes.\n\nThe Opportunity\nWe 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.\nAs 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.\nWhat You’ll Do\nCollaborate with colleagues and be a strong voice in product design sessions, architecture discussions, and code reviews.\n\nDesign, implement, test, debug, and document work on new and existing software features and products, ensuring they meet business, quality, and operational needs.\n\nTake 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.\n\nUse agentic coding tools to write clear, efficient, and scalable code with an eye toward flexibility and maintainability.\n\nOwn and contribute to team productivity and process improvements.\n\nUse and develop APIs to create integrations between Plug and third-party platforms.\n\nActively raise the technical bar of the team through thoughtful code review, pairing, and knowledge sharing, including how you use AI tools.\n\nBe 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.\n\nWhat You’ll Bring\n5-8 years of hands-on experience developing and delivering production applications.\n\nDemonstrated proficiency in TypeScript across the full stack: backend, frontend, relational databases, and API and webhook integrations. Temporal experience is a strong plus.\n\nHands-on experience deploying and operating cloud-hosted applications. Comfort with infrastructure-as-code (we use Terraform), CI/CD pipelines, feature flags, and observability tooling.\n\nExperience in agent-first development workflows: comfortable orchestrating multiple agents, defining clear acceptance criteria, and reviewing AI-generated output with a high quality bar.\n\nA 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.\n\nConsiders cross-surface and downstream implications of technical decisions. Writes code and designs systems that other engineers can understand, extend, and depend on.\n\nPrior startup experience and a track record of owning work end to end: scoping, shipping, and measuring impact.\n\nAuthorized to work in the US for any employer.\n\nPrior experience in automotive or EV systems is a plus.\n\nCompensation and Benefits\nAnnual salary: $175,000 to $215,000\nSalary ranges reflect independent, third-party benchmarking against national compensation data. Where an individual’s actual offer falls within that range depends on a combination of factors, including relevant experience, specialized skills, training and qualifications, current business needs, and prevailing market conditions. Ranges are reviewed periodically and may be adjusted to reflect changing market conditions.\nBenefits & Perks\nHealth, Vision, and Dental insurance\n\n401(k) plan\n\nDaily lunch stipend\n\nEquity (based on role and performance)\n\n30-day remote work from anywhere policy\n\nUnlimited PTO\n\nFully stocked kitchen\n\nDog-friendly office\n\nOngoing opportunities for growth and development\n\nThis full-time position is based in Sawtelle (between Santa Monica and West Los Angeles) and is an in-person role.
