At Underdog, we make sports more fun.

Our thesis is simple: build the best products and we’ll build the biggest company in the space, because there’s so much more to be built for sports fans. We’re just over five years in, and we’re one of the fastest-growing sports companies ever, most recently valued at $1.3B. And it’s still the early days.

We’ve built and scaled multiple games and products across fantasy sports, sports betting, and prediction markets, all united in one seamless, simple, easy to use, intuitive and fun app.

Underdog isn’t for everyone. One of our core values is give a sh*t. The people who win here are the ones who care, push, and perform. If that’s you, come join us.

Winning as an Underdog is more fun.

We’re looking for a Senior Product Designer specializing in motion design to shape how our product moves, responds, and feels. You’ll use motion to clarify complex interactions, guide attention, communicate system status, and add craft to every touchpoint without sacrificing performance or accessibility. You’ll partner closely with Product, Engineering, Product Design, and Brand to define a motion language that scales across our experiences.

What you’ll do

Collaborate on and lead motion design across the product: define principles, patterns, and guidelines for interaction and UI motion.
Design high-quality microinteractions (transitions, state changes, loading/empty states, feedback, onboarding moments) that improve usability and delight.
Prototype early and often using motion-forward tools to explore interaction models and validate concepts quickly.
Partner deeply with engineers to ensure motion is implemented accurately, efficiently, and accessibly; provide specs and support QA.
Create reusable motion components and contribute to the design system (tokens, curves/easing, durations, choreography rules).
Improve product comprehension with motion that communicates hierarchy, cause/effect, and status (errors, success, progress, latency).
Use research and data to evaluate motion effectiveness (comprehension, conversion, time-to-complete, error reduction).
Mentor designers and up-level motion craft across the team via reviews, critiques, and workshops.
Collaborate with Brand/Marketing when needed to ensure motion feels cohesive across product and storytelling surfaces.

Who you are

3-5 years of product design experience, with strong motion design emphasis in shipped digital products.
A portfolio showcasing interaction design + motion craft with clear problem framing, process, and outcomes.
Expert understanding of timing, easing, choreography, and narrative flow for UI motion.
Strong systems thinking: ability to create scalable patterns rather than one-off animations.
Deep collaboration skills with engineering; comfort discussing implementation constraints (performance, platform behaviors, rendering).
Fluency in accessibility and inclusive design, including reduced motion strategies and motion-sensitivity considerations.
Excellent communication: you can explain why motion choices matter and align stakeholders around tradeoffs.
Experience working across web and/or mobile platforms (iOS/Android) in cross-functional teams.

Even better if you have

Experience building or maintaining a motion system within a design system (tokens, guidelines, governance).
Familiarity with implementation frameworks (e.g., Rive, Lottie, After Effects pipelines, CSS/JS animations, Framer Motion) or platform-native approaches.
Experience with complex product areas (data-heavy UI, sports gaming, finance).
Comfort with metrics-driven iteration and experimentation.

Our target starting base salary range for this position is between $150,000 and $190,000, plus target equity. The starting base salary will depend on a number of factors including the candidate’s skills and experience, among other things.

What we can offer you:

Unlimited PTO (we're extremely flexible with the exception of the first few weeks before & into the NFL season)
16 weeks of fully paid parental leave
Home office stipend
A connected virtual first culture with a highly engaged distributed workforce
5% 401k match, FSA, company paid health, dental, vision plan options for employees and dependents
