Senior Software Engineer

About Us

At Addi, we are pioneering the future of advertising through cutting-edge AI. Our platform empowers brands to produce broadcast and streaming-quality audio and visual ads in seconds, eliminating the need for studios, voice actors, or complex production processes.

We're more than just developers, we're innovators committed to transforming how brands connect with audiences. Our collaborative environment encourages curiosity and agility, allowing your ideas to directly shape the future of AI-driven media.

You'll work across generation pipelines, ad-platform integrations, custom server-driven UI (SDUI), and our observability and reliability stack. Expect feature work alongside substantive core engineering. You’ll write, refactor and simplify code, improve and redesign systems, reconsider inherited assumptions, research and run experiments, and make things faster and more efficient.

Small team, carefully chosen. We hire engineers fluent with coding assistants as accelerators for engineering judgment, not substitutes. High bar, low ego. Strong opinions held loosely, decisions that stick.

Our hybrid team is primarily based across Kansas City with some remote employees. Our hybrid model includes two in-office days per week (Mondays & Wednesdays) where we collaborate as a team, have fun, eat free food, and build new ideas. The remainder of the week is optional in-office and flexible schedules.
