Software Engineer - Senior Software Engineer

About Agentio

Agentio is building the future-state of digital advertising — where AI, creators, and brands converge.

We’re on a mission to transform a $600B digital ad ecosystem by shifting digital ad spend into the hands of creators. Our AI-native platform is transforming the entire creator ad buying process— seamlessly delivering performant, scalable, and authentic creator-led marketing.

Agentio removes the friction of traditional sponsorships, compressing weeks of manual work into seconds. We enable brands like Uber, DoorDash, and Bombas to buy creator media like they buy Meta or Google ads — but with the power of voice, trust, and influence. True word-of-mouth at scale.

Agentio’s investors include Benchmark, Craft, and AlleyCorp. Agentio has been named to Forbes’ list of Next Billion Dollar Startups, 2025. We've raised $16M to date, our product is already used and loved by the world’s leading marketers and creators— and we’re just getting started. Our world-class team is redefining the infrastructure for creator-led performance media.

About the Role

We’re looking for a senior software engineer with experience in early-stage or high-growth environments to join our team.

Every week, you’ll ship real functionality and have the autonomy to tackle meaningful, complex engineering problems.

You’ll be tackling complex challenges in marketplace design, multimodal content understanding with large models, and campaign optimization in a high-performance environment where technical decisions directly shape product direction and business outcomes.

This is a rare opportunity to get in early at a generational company redefining how advertising works for brands and creators. If you're excited by ownership, fast execution, and real-world impact, this could be a great fit.
