Front•San Francisco, CA

About The Position

Front is a customer operations platform designed for B2B complexity, ensuring that every team, tool, and customer conversation remains synchronized to help companies scale effectively without losing personal connection. Unlike platforms that handle simple interactions, Front specializes in the coordination and context required for complex B2B customer relationships. Over 9,000 companies, including major players like Uber Freight, Navan, and Stripe, depend on Front for its unique ability to manage the operational layer crucial for successful customer-facing work. The company is backed by Sequoia Capital and Salesforce Ventures, having raised $204M from leading venture capital firms and independent investors. Front has also received numerous accolades, including being named one of Built In's 100 Best Midsize Places to Work in SF 2025, a Top Place to Work by USA Today 2025, and #4 on Fortune’s Best Workplaces in the Bay Area™. At the core of Front's engineering efforts is the Foundations team, which empowers the rest of the engineering department to build rapidly and confidently. This team is responsible for the frameworks, libraries, and internal systems that drive Front's backend, encompassing everything from its event-driven task queue to its CI/CD infrastructure and database ORM. As a Software Engineer on the Foundations team, you will operate at the intersection of platform engineering and developer experience, focusing on building the foundational systems that enable user-facing features rather than the features themselves. This role is ideal for individuals passionate about designing for scale, streamlining engineering workflows, and establishing the architectural standards that guide the entire company.

Requirements

Experience building frameworks, libraries, and/or developer-facing internal tools
Experience building distributed systems with an emphasis on reliability, observability, and performance

Clear, structured thinking and strong communication skills — your stakeholders are other engineers, so the ability to explain technical tradeoffs matters
Comfort navigating ambiguity: you can drive clarity and execute without a fully-defined roadmap
Ability to thrive in a dynamic, fast-paced, collaborative, low-ego, and high-growth environment
Backend JavaScript/TypeScript engineers (this role is not focused on frontend development)

Deep TypeScript performance optimization experience
Prior work on platform or enablement teams at a product-led company
