At Fetch, engineering is driven by curiosity, ownership, and a bias toward action. We operate in complex problem spaces where the right answer is not always clear, and success depends on adaptability, critical thinking, and informed decision‑making. Our engineers are comfortable navigating ambiguity, understanding tradeoffs, gathering context, and turning uncertainty into progress while maintaining high technical standards.

Engineers at Fetch take pride in building reliable, scalable systems that serve millions of users. You will contribute directly to the codebase, collaborate closely with cross‑functional partners, and help shape best practices that elevate the quality of our work. We foster a culture of mentorship and collaboration, where engineers grow by learning from one another and holding a high bar for quality, reliability, and impact.

Fetch is entering its AI‑first era, and we’re looking for a Principal Software Engineer to design, scale, and evolve the intelligent systems that power personalized consumer and advertising experiences for millions of users.

You will design and evolve the platforms that unify data, real‑time learning, inference, and delivery, enabling Fetch to serve more relevant, trustworthy, and high‑performing Ads while supporting a rapidly scaling consumer business. This role requires a combination of architectural depth, Ads systems expertise, and the ability to influence technical strategy across teams.

Operating at the intersection of ad intelligence, experimentation, and large‑scale distributed systems, you will be a key technical force advancing Fetch’s monetization engine. You’ll collaborate with Product, Data Science, Platform, and ML teams to drive clarity, define architectural standards, and ensure our Ads systems become more adaptive, more measurable, and more efficient over time.

This is a hands‑on, high‑impact technical leadership role with influence across multiple engineering collectives. Your work will shape how Fetch evolves its Ads stack: relevance, ranking, performance, measurement, and revenue integrity at scale.

This role can be based in one of our US offices or remotely within the United States.
