Senior Copywriter (Brand)

Welcome to Fi.

We’re a passionate team from Square, Google, Peloton, Uber, and more working to transform the dog-human relationship. Our mission? Develop cutting-edge technology to revolutionize what it means to be a dog parent.

The dog 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 the millions of dogs 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 dogs and humans. Imagine a world where everyone knows how their dog 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 dogs 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 dog ownership together.

Fi is looking for a Senior Copywriter!

As a Senior Copywriter at Fi, you’ll join our internal brand and creative team to craft sharp, brand-defining work across everything from performance ad copy and email to larger conceptual campaigns. You’ll report directly to the ACD and work closely with our designers, marketers, and product partners to tell compelling stories about our product, and the people (and pets) who use it.

This is a hybrid role that spans both high-level campaign thinking and fast-moving day-to-day creative. You’ll own our brand voice across channels and help shape how the world sees and understands Fi. You should be equal parts strategic and expressive: comfortable developing concepts from the ground up, writing performance copy that converts, and refining brand tone in a way that scales.

We’re looking for someone who’s proactive, collaborative, entrepreneurial, and energized by both short- and long-form storytelling. A love of dogs doesn’t hurt either.

• Own copywriting across brand touchpoints, from performance marketing (paid social, email, landing pages) to bigger brand campaigns, retail moments, and product storytelling
• Develop strong concepts in collaboration with designers and marketers that elevate the brand and move the business forward
• Champion and evolve Fi’s tone of voice to ensure consistency and originality across channels
• Write tight, conversion-focused copy that resonates with specific audiences and drives action
• Balance brand craft with performance insights, writing with both heart and data in mind
• Translate product features into benefit-driven, emotionally compelling messaging
• Present work clearly and confidently to cross-functional stakeholders
• Support the creation of creative briefs, campaign messaging hierarchies, and testing plans when needed
• Bring entrepreneurial energy to new opportunities, helping Fi punch above our weight with small but mighty ideas

• 5–7+ years of copywriting experience in an agency or in-house creative environment
• A portfolio that demonstrates sharp conceptual thinking, strong brand voice, and a range of campaign and performance writing
• Experience writing for DTC or consumer tech brands (bonus for work in lifestyle, wellness, or pet industries)
• Ability to shift between big-picture campaign work and fast-moving daily copy needs
• Comfortable working in collaborative, iterative environments and presenting work to stakeholders
• Excellent time management and attention to detail
• Self-starter with a scrappy, entrepreneurial mindset and a passion for making great work happen
• A personal interest in the pet, tech, or wearables space is a plus—but not required

• Time to Recharge: Enjoy flexible PTO to take the breaks you need.
• Top-Notch Health Coverage: We’ve got your back (and teeth and eyes) with full medical, dental, and vision insurance.
• Wellness Perks: Free access to One Medical, Kindbody, and Talkspace to keep you feeling your best.
• Give Back to the Pups: Make tails wag with a $500 annual donation to a dog charity of your choice through our BarkBack Program.
• Free Fi Membership: Your furry best friend(s) get all the benefits of a Fi collar, on us!
• Love for Friends + Family: Share the Fi magic with loved ones through our gifting program.
