Software Engineer - Senior Software Engineer

Agentio enables marketers to buy creator led ads as easily and scalably as Meta or Google ads—automating sourcing, pricing, contracting, delivery, and measurement—so work that took months now happens in minutes.

We’re on a mission to transform a $600B digital ad ecosystem by shifting digital ad spend into the hands of creators. That means better outcomes for marketers and enabling creators to live off their work—finally being paid in proportion to the value they create. That shift is accelerating: Unilever’s CEO has said the company will move roughly half of its ad budget into social and creators—Unilever is among the world’s largest advertisers, spending around $9–10B annually. As these dollars move, they need performance-grade pipes; Agentio is how those dollars flow to creators with the speed, control, and measurement marketers expect. We enable brands like Uber, DoorDash, and Bombas to run creator campaigns with the same rigor, control, and accountability as their core performance channels.

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.

We’re looking for a senior software engineer with experience in early-stage or high-growth environments to join our team. As a foundational member of engineering, you’ll work directly with our founders to design, build, and launch new product features—from first lines of code to production. 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.
