If you are passionate about building highly reliable, frontend-focused systems that directly impact business growth, we would love to have you join our team.

About the Team

The Marketing Technology (Mar Tech) team is a new group building the next generation of infrastructure that powers customer acquisition and engagement funnels. We prioritize quality, observability, and uptime to support Gusto’s growth and brand, partnering closely with Marketing, Sales, Growth R&D, and Operations.

Day-to-Day Responsibilities

• Architect and evolve customer-facing web platforms for performance and scale.
• Build and maintain integrations with our Mar Tech stack (e.g., Segment, Braze).
• Implement and optimize caching strategies across the delivery stack (CDN, edge).
• Write high-quality, well-tested frontend code using modern best practices.
• Support, mentor, and up-level fellow engineers on the team.
• Partner cross-functionally with Marketing and Sales to translate business needs into technical solutions.
• Own the long-term technical roadmap for Mar Tech.

What We’re Looking For

• 12+ years of experience building web systems connected to a headless CMS.
• Experience building modern frontend applications with React, Type Script, and Next.js.
• Experience with web performance, CDNs, and advanced caching strategies.
• Experience integrating with Mar Tech systems (e.g., CDPs, CRMs, orchestration tools).
• Systems thinker with excellent written communication and collaboration skills.
• Ability to act as a thought partner for technical and business teams.
• A balance of pragmatic execution and long-term architectural thinking.

Compensation

Cash compensation is targeted at $191,000–$225,000/year in Denver and most remote locations, and $225,000–$265,000/year for San Francisco, Seattle, and New York. Stock equity is additional. Final offer amounts depend on candidate experience and may vary from the amounts listed above.

Gusto has physical office spaces in Denver, San Francisco, and New York City.
