Job description

Career Renew is recruiting for one of its clients a Principal Frontend Engineer - this is a hybrid role in San Francisco. Salary range: $220K–$270K + bonus (10-12%) + significant equity.
We’re igniting a collectibles revolution. Backed by legendary 5× World Series Champion Derek Jeter and trailblazer Brian Lee, we’ve launched the first-ever digital card show—a dynamic marketplace where innovation, transparency, and pure excitement drive everything we do. Our cutting-edge platform offers unparalleled grading, authentication, secure vaulting, and digital pack openings (Slab PacksTM), giving collectors the power to curate unique online showrooms and redefine their collecting experience.

We are looking for a Principal Frontend Engineer with 8-15 years of experience to serve as the technical authority and discipline lead for our web platform. You'll be a visionary architect who defines the long-term frontend strategy for a high-growth digital marketplace expanding into new collectible categories — currently scaling from 1.5 billion to 2.5 billion transactions per month. This is a role for mobile first web engineers who are deeply opinionated about system architecture and performance, and able to ensure our platform handles massive traffic spikes during drops, live auctions, and promotional events. You'll collaborate closely with product, marketing, and engineering leadership in a flat, low-ego environment where strong communicators thrive.

What will you be doing?

  • Define and own the architectural vision for all our web applications, ensuring systems are modular, performant, and resilient at scale

  • Lead the modernization of the frontend architecture — migrating monolith repos to microservices and building net-new category launches (new categories ship in 2-3 months)

  • Design high-concurrency frontend systems that can handle a million+ users hitting the site within minutes during drops and promotional moments

  • Set the standard for the frontend discipline — establishing patterns, build pipelines, and best practices across the engineering org

  • Partner with product, marketing, and executive leadership to influence the roadmap and ensure technical debt is managed as the platform rapidly scales into new categories

Requirements:
8 - 15 years of experience in frontend engineering with 2+ years in staff/principal roles, at B2C companies (Mandatory)
2+ years in staff/principal architectural leadership capacity; owned frontend architecture end-to-end, not just shipped features (Mandatory)
Experience at a marketplace, e-commerce, or real-time consumer platform (e.g., Goat, StockX, Fanatics, DraftKings, Uber) (Mandatory)
Designed systems handling high-traffic events (drops, auctions, promotions, live transactions) for real users (Nice-to-have)
Degree in Computer Science or related technical field (Mandatory)
Expert in React, TypeScript, and Next.js (Mandatory)
AI-native engineering; fluent in Claude, Cursor, can flex into an in-house harness for daily development (Mandatory)
Strong system architecture and web performance optimization experience (Mandatory)
Experience with SSR/SSG, AWS, and modern build tools (Nice-to-have)
Can set standards and design direction for a growing, distributed team (Mandatory)
Articulates technical decisions clearly to non-technical stakeholders (product, marketing, execs) (Mandatory)
Consumer-facing depth; has built dynamic, user-facing products at scale (Mandatory)
