About Poshmark

Poshmark is the leading fashion marketplace where style comes alive through discovery, self-expression, and human connection. Powered by a vibrant community of 165 million members, Poshmark brings real people and taste to shopping through a social experience shaped by shared discovery. Buying and selling fashion feels simple, joyful, and personal, while every item tells its own story. Poshmark empowers sellers to grow meaningful businesses, keeps fashion in circulation longer, and gives shoppers access to unique and trusted finds, from everyday pieces to one-of-a-kind vintage and luxury.

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.

How to prepare and behave

This is editorial guidance, not information from the employer.

• Read the whole description and match your examples to its requirements; use the same words the posting uses where they are true for you.
• Research the employer before the interview: what it does, who its customers are and recent news; prepare two or three questions about the work.
• Arrive early (or log in early for a video call), dress one step above the daily dress code, and test your camera and audio beforehand.
• Answer with short stories: the situation, what you did and the result. Give numbers when you have them and never invent them.
• Be honest about gaps; say what you did to learn and how fast you can close them.
• Ask about the team, the first 90 days, how success is measured and the schedule; do not open with salary and time off.
• When pay comes up, know the market range for the occupation and your lowest acceptable offer before you answer; ask for the full package in writing.
• Send a short thank-you message within a day, mentioning one thing you discussed.
• The listing mentions a remote or flexible location. Confirm with the employer whether remote work applies to your state: taxes, licensing and benefits can depend on where you live.
• Have code, data work or projects you can show, and be ready to think aloud: many technical interviews test how you reason, not only the answer.

The city

The job is in Redwood City, CA. Below is what the official statistics say about living and working there.

How Redwood City compares. Among the 145 largest places in California, Redwood City is #106 by population, #125 for rent (#1 = cheapest), #22 for long commutes (#1 = fewest), #26 for household income (#1 = highest). Its county, San Mateo County, is #2 of 58 counties for average pay ($196,441).

The place in numbers

Redwood City has 82,447 residents (ACS 2020–2024), about 0.2% of the population of California. It covers 19 square miles of land, which works out to roughly 4,264 people per square mile. The median age is 37.5, about the same as the state median (37.5 against 37.9).

Housing

The median gross rent is $2,968 a month (rent plus utilities), 46% above the state median ($2,968 against $2,036). Over a year that is 22.6% of the median household income. US housing guidance treats housing as affordable when it takes 30% of income or less, so the typical household is under that line. The median home value is $1,801,700, which is 11.4 times the median household income ($157,814); a ratio above 5 usually means buying is out of reach without savings or a second income. 48.6% of households own their home, 13% below the state average (48.6% against 55.9%).

Work and pay

The San Francisco-Oakland-Fremont, CA metropolitan area has 2,373,920 jobs in the BLS wage survey, and the median pay across all occupations is $74,260 a year, 46% above the national median ($74,260 against $50,980). The biggest occupation groups are office and administrative support (226,320 jobs, median $62,120); management (223,100 jobs, median $176,340); business and financial operations (207,030 jobs, median $112,960). The area is most specialised in computer and mathematical (1.9 times) and life, physical, and social science (1.8 times), where the share of workers is well above the national share. The best-paying groups with at least 5,000 jobs are management ($176,340) and computer and mathematical ($167,770). In 2026M09 the unemployment rate of San Mateo County was 3.9%. 68.8% of residents aged 16 and over are in the labour force. The city lies in San Mateo County; its jobs, pay by industry and GDP are on the county page.

Getting around

Among workers, 55.2% drive alone, 3.8% use public transit, 2.4% walk, 26.7% work from home. 10.2% of workers commute 45 minutes or more, 47% below the state average (10.2% against 19.4%). Remote work is more common than in the state as a whole, which widens the set of employers a resident can work for without moving.

People and education

54.4% of adults aged 25 and over hold a bachelor's degree or higher, 47% above the state share (54.4% against 37.1%). 32.9% of residents were born outside the United States, 22% above the state share (32.9% against 27.0%). The poverty rate is 6.3%, 48% below the state rate (6.3% against 12.0%).

Climate

The warmest month is Sep, averaging 61°F (16.0°C), and the coolest is Jan at 51°F (10.7°C). About 515 mm (20 inches) of precipitation falls in a year; Dec is the wettest month (115 mm) and Jul the driest (2 mm). These values come from NASA satellite-based climatology on a grid of about 50 km, so they describe the wider area, not a weather station in the city.
