Full Job Description
Job Title: Sr. Full-Stack Engineer

Team: Engineering

Location: Onsite - Sawtelle (Between Santa Monica & West LA)

Employment Type: Fulltime, Salary, Exempt

Reports To: Engineering Lead

The Opportunity

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.

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 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.


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/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.
