Welcome to Fi.

We’re a passionate team from Square, Google, Oura, Peloton, Uber, and more working to transform the human-pet relationship. Our mission? Develop cutting-edge technology to revolutionize what it means to be a pet parent. The pet industry remains firmly stuck in the past and we are here to change that. Fi is leveraging our team's talent and expertise to improve the lives of millions of pets in the U.S. Real-time location tracking, activity, sleep and behavior monitoring – and that's just the beginning.

The most exciting aspect of our work? Bridging the communication gap between pets and humans. Imagine a world where everyone knows how their pet feels in real time and how to keep their best friend in good shape. That's the future we're building at Fi.

If you're someone who thrives in innovative, collaborative work environments and feels strongly about helping pets live longer, better lives, Fi could be the perfect fit. Join us in our pursuit of the “impossible,” or as we call it here “let me find a way,” to redefine the future of pet ownership together.

Fi is looking for a Head of Copy!
Fi is looking for a Head of Copy to own how Fi sounds everywhere a customer meets us, from a campaign headline to an escape alert at 2am. We build the technology that keeps dogs safer, healthier, and more deeply understood, and what we do is complex. Language is how we make it clear. Every word in a campaign, app notification, onboarding flow, email, or retail display shapes how people feel about Fi, and each of those channels asks something different of our voice. You’ll set that voice and build the system that holds it together.

What You'll Do:

Define and own Fi’s verbal identity: voice, tone, messaging architecture, and how it flexes across brand, marketing, product, CX, and retail
Build the voice system, including guidelines, frameworks, terminology, and standards that every writer, designer, PM, and agency partner can actually use
Set creative direction for copy on major brand campaigns, product launches, and retail moments, and hold the bar on everything that ships
Partner with product and design to shape UX writing across the Fi app, onboarding, notifications, and in-product messaging
Hire, lead, and develop a team of writers, and set how copy gets briefed, reviewed, and approved across the company
Turn complex technology and data into language that’s clear, human, and emotionally compelling
Shape positioning and messaging hierarchies with marketing and product so every channel tells the same story
Bring data into the craft by partnering with growth on testing and using performance insights to sharpen the system, not just individual lines
Present, defend, and evolve creative vision with the executive team and cross-functional stakeholders

What You'll Bring:

7+ years in copy, content, or verbal identity, with meaningful time leading writers in-house or at an agency
You’ve built a rigorous, multi-dimensional, cross-functional voice system before and can walk us through how it held up at scale
Real range across brand, marketing, and product/UX writing. An advertising background is welcome, but ads are one piece of the pie
A portfolio that goes well beyond ad copy: voice systems, product experiences, messaging frameworks, and the campaigns built on top of them
A clear POV on how a brand should sound at every level, with the conviction to defend it and the clarity to delegate it
Deep experience working side by side with design, and comfort being a creative leader in the room, not just the writer in it
Experience at DTC or consumer tech brands, ideally where the product is complex and the stakes are emotional
The appetite to challenge norms, set vision, and help a small team punch well above its weight
