Principal Engineer

About the role

ABOUT VALID

Valid is one of the fastest-growing AI-native marketing companies. We’re building the company that replaces the traditional marketing agency.

We help brands grow across Meta, TikTok, Google, and TV by combining software, AI agents, creative production, and media buying into a single system. Every day, we launch, measure, and iterate on advertising campaigns at a speed that traditional agencies can’t match.

Our team operates at the intersection of AI video, filmmaking, performance marketing, and engineering. We believe the future of marketing isn’t people or AI, it’s people working alongside AI systems to produce better work, faster.

The model is already working. Valid manages more than $40M in annualized advertising spend and partners with some of the fastest-growing consumer and technology companies, including Replit, Rover, Tolan, and others. Since launching, we’ve consistently won head-to-head against incumbent agencies by delivering better performance and moving faster.

Backed by Canaan, Neo, Steve Huffman, Scott Banister, and other leading investors and operators, we’re building the next generation of marketing.

- Seasoned in architecting and implementing high scale and throughput systems

- Accomplished in leading engineering teams in delivering game-changing products

- Skilled at partnering with product and business counterparts in roadmap and decisioning

You lead and mentor our engineering team in executing and delivering against our aggressive roadmap, and as Valid's prospects and mandate grow, so too do your role and responsibilities. In short, your execution and dedication as Principal Engineer will be a key factor in Valid's success.
