Poshmark is looking for a Senior Web Engineer II to join our Buyer Pod. We are the team responsible for the core user journey: feed, discovery, search, and listing details. We don’t just build interfaces; we build the engine that helps millions of users find and buy what they love.
We are looking for an engineer who values the "how" as much as the "what." You should be someone who understands the browser’s rendering pipeline and DOM underpinnings deeply, ensuring that our migration from Vue 2 to Vue 3 is not just a version bump, but a leap forward in performance and code quality.
Core Responsibilities
Architect & Execute: Lead small engineering pods to take complex features from discovery to production-scale delivery.
The Vue Migration: Act as a key driver in our transition from Vue 2 to Vue 3, leveraging the Composition API and modern build tools (Vite/Webpack).
High-Performance UI: Build responsive, accessible, and high-performance web applications with a focus on Core Web Vitals and efficient state management.
Design Partnership: Collaborate closely with Product and Design to ensure every pixel serves the user experience. You should bring a strong "sense of taste" to everything you build.
Technical Mentorship: Influence the technical roadmap and mentor junior/mid-level engineers through code reviews and architecture discussions.
90-Day Success Metrics
Immediate Impact: Contribute production-ready code to both our legacy and modern environments within your first 30 days.
Migration Milestone: Successfully migrate a complex module or shared component from Vue 2 to Vue 3.
Feature Ownership: Lead the technical execution of a new buyer-facing feature, ensuring it meets our standards for performance and design polish.
12-Month Success Metrics
Architecture Evolution: Propose and implement structural improvements to our web stack that measurably improve developer velocity and site speed.
System Expert: Become the primary technical point of contact for our search and discovery front-end architecture.
Team Growth: Level up the team’s collective knowledge of browser internals and modern JavaScript best practices.
Desired Skills
5+ years of software development experience, with a focus on high-scale web applications.
Under the Hood Knowledge: Deep understanding of JavaScript fundamentals (Event Loop, DOM API, browser rendering) beyond framework-specific abstractions.
Vue Specialist: Proven experience with Vue 2 and Vue 3. Experience navigating the friction of migrating between the two is highly preferred.
Leadership: Experience leading small teams or project "pods" and a track record of driving features to completion.
Product Intuition: A sharp eye for UI/UX and a passion for creating "great" web design rather than just "functional" code.
The Stack: Familiarity with modern build tools (Vite, Webpack), RESTful APIs, and distributed systems.
Skills Required
- 5 years software development experience
- At least 2 years in building responsive web applications
- Bachelor's degree in Computer Science or a related field
- Experience with Node, Vue, React, Angular, Ruby on Rails, MongoDB, AWS
