Senior Software Engineer

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.
