About The Position

Faire is seeking a Senior Fullstack Ads Engineer to join their Ads team. This is a high-visibility, high-impact role focused on building the ads platform that powers the shop local movement. The Ads team is expanding, offering an opportunity to shape the product direction. The role involves end-to-end ownership of projects across frontend, backend, and data, partnering with PMs and designers, contributing to Faire's server-driven UI framework, optimizing frontend performance, utilizing AI tooling, and mentoring other engineers.

Requirements

5+ years of full-time engineering experience.
Strong frontend depth in TypeScript and React; you can own a complex fullstack project top to bottom.
Product-driven and customer-centric; you think about our customers, not just the technology.
Comfortable in high-ambiguity environments; you move fast, communicate clearly, and don't wait for perfect specs.
AI tooling is genuinely part of how you work today; you can speak to what you use, what works, and what doesn't.

Nice To Haves

Background in ad tech, ads manager tools, or customer-facing analytics.
Experience leading a complex frontend project with multiple stakeholders, or mentoring a small group of frontend engineers.
Hands-on experience with data pipelines (Airflow, Spark, or similar).

Responsibilities

Own projects end to end, across frontend, backend, and data.
Partner with PMs and designers to define the why and what, not just the how.
Contribute to Faire's server-driven UI framework: set technical direction, ensure scalability, and drive adoption across the team.
Optimize frontend performance using Next.js and modern web techniques.
Use AI tooling as a genuine part of your workflow, not as an experiment.
Raise the bar for the engineers around you through code review, pairing, and sharing what you know.
