What we’re building and why we’re building it.

Every month, millions of people use Fetch, earning rewards for buying brands they love, and a whole lot more. Whether shopping in the grocery aisle, grabbing a bite at the drive‑through or playing a favorite mobile game, Fetch empowers consumers to live rewarded throughout their day. To date, we’ve delivered more than $1B in rewards and earned more than 5M five‑star reviews from happy users.

It’s not just our users who believe in Fetch: with investments from Softbank, ICONIQ, DST, Greycoft, and partnerships ranging from challenger brands to Fortune 500 companies, Fetch is reshaping how brands and consumers connect in the marketplace. When you work at Fetch, you play a vital role in a platform that drives brand loyalty and creates lifelong consumers with the power of Fetch points.

User and partner success are at the heart of everything we do, and we extend that same commitment to our employees.

At Fetch, we value curiosity, adaptability, and the confidence to explore new tools, especially AI, to drive smarter, faster work. You don’t need to be an expert, but you should be ready to learn quickly and think critically. We welcome learners who move fast, challenge the status quo, and shape what’s next, with us. Ranked as one of America’s Best Startup Employers by Forbes for two years in a row, Fetch fosters a people‑first culture rooted in trust, accountability, and innovation.

We encourage our employees to challenge ideas, think bigger, and always bring the fun to Fetch.

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 a pivotal phase where user lifecycle growth is the company’s north star for 2026. The Growth Engineering organization owns the platforms and product systems that drive acquisition, activation, engagement, retention, and reactivation across the Fetch consumer ecosystem. This team focuses on accelerating experimentation, improving user journeys, and building the engagement infrastructure that systematically increases MAU growth, retention, and lifetime value.

As a Principal Engineer in Growth, you will operate as a senior technical leader responsible for shaping the architecture, scalability, and evolution of these platforms. You will partner closely with Engineering, Product, Growth Marketing, and Data to design systems that enable faster experimentation, stronger engagement loops, and measurable growth outcomes.

This is a hands‑on technical leadership role with influence across multiple teams. You will guide system design, define technical standards, and mentor engineers while helping the organization move faster without sacrificing reliability or long‑term system health.

This is a full‑time role that can be held from one of our US offices or remotely in the United States.
