Senior Software Engineer, Consumer Facing Web Products

We're looking for a Senior Full-Stack Software Engineer with a strong sense of product to join our team. You'll work across the stack, but your primary focus will be delivering modern, high-performance user experiences that balance speed, usability, and search visibility. You embrace AI development tools as part of your everyday workflow, using them to move faster without sacrificing quality.

You'll collaborate closely with product managers, designers, and other engineers to build scalable, engaging shopping flows, while also contributing to performance, observability, accessibility, and technical excellence. This is a hands-on engineering role, ideal for someone who thrives in fast-paced environments, has a strong product mindset, and is motivated by seeing their work used by millions of users.

Where you can make an impact:

• Build, maintain, and evolve React/Next.js front-end applications that serve millions of monthly users.
• Improve Core Web Vitals, accessibility, and technical SEO to drive discoverability and engagement.
• Partner with product, SEO, and content teams to launch, test, and iterate on high-impact shopping experiences.
• Design and implement backend APIs and services that power dynamic, personalized content, rapid experimentation and partner integrations.
• Collaborate on platform-wide initiatives: performance, observability, A/B testing infrastructure, and front-end developer experience.
• Contribute to shared UI components and design systems, helping scale high-quality UX across pages.
• Use AI coding tools and spec-driven workflows as part of your day-to-day, contributing to the team's growing dev harness and automations.
• Participate in code reviews, mentorship, and team technical discussions to help raise the engineering bar.

Your experience:

We recognize not everyone will meet all of the criteria. If you meet most of the criteria below and you’re excited about the opportunity and willing to learn, we’d love to hear from you.

• 6+ years of software engineering experience, with meaningful contributions across both front-end and back-end systems.
• Deep experience in TypeScript, React.js, and Next.js or a related isomorphic framework (Astro, Gatsby, etc.).
• Strong product and UX sensibility with a keen eye for performance, usability, and responsive design.
• Hands-on experience building and consuming RESTful and GraphQL APIs, integrating with databases (SQL/NoSQL), and writing full-stack features.
• Hands-on experience with AI coding tools (e.g. Cursor, Copilot, Claude Code) as part of your regular development workflow.
• Familiarity with cloud infrastructure (e.g. AWS, GCP, Vercel) and modern DevOps practices (CI/CD, observability).
• Excellent communication skills and a collaborative mindset.

Preferred Qualifications:

• Experience working in public-facing, high visibility shopping marketplaces.
• Background in FinTech, financial services, or other regulated industries.
