Job description

Senior Product Designer

We're looking for a Senior product designer to help shape the next layer of SeenThis: a product where creative and marketing teams can build, run, measure, and improve high-performing video campaigns across channels.

This is a role for an AI-native designer who likes complex problems, expert users, and fast execution. You'll work close to product and engineering, own meaningful parts of our media and advertising product suite, and help turn complicated workflows into tools people want to use every day.

About SeenThis

The open web has massive untapped advertising potential, but video has historically underperformed here. SeenThis is changing that. As a video advertising partner, we prove the open web delivers exceptional results, capturing more attention with cost‑effective video that keeps publishers profitable and the internet independent. Since 2017, we've served billions of streams for 5,000+ brands across 50+ countries. We believe brands deserve reach wherever audiences are, publishers deserve sustainable revenue, and the internet deserves to stay open.

Our team of 130+ employees works globally from offices in Stockholm, Oslo, London, Paris, Singapore, Hong Kong, New York, and Sydney. We're expanding across all teams and constantly seeking new colleagues who want to make real impact in a fast‑moving, collaborative environment where innovation happens daily.

About the role

Our adaptive streaming technology fixed the delivery problem for video advertising. Now we're building the product layer on top.

You will own parts of our media and advertising product suite, working closely with engineers, a PM, and the Design Lead to take ideas from first sketch to shipped product. You will help define how our product works, how it feels, and how product design works at SeenThis as the function continues to grow.

While you will iterate and build fast, your role starts with discovery. You will become a domain expert for your part of our products by continually talking with customers, mapping their workflows, understanding the business context, and finding real problems.

You will be expected to figure out what’s worth building before any screen is designed. Sometimes that means proper research or session data; other times, a client call and a rough prototype may be the answer. That’s up to you.

Getting this right is most of the job, because the wrong thing built well is still the wrong thing.

This is also an execution‑first and AI‑native role. You’ll move quickly from problem to prototype to shipped product, using tools like Claude Code to explore ideas, test flows, and iterate faster.

Building is cheap now; judgment is the scarce part. When AI can produce the screen, the work that matters is deciding what to build, what to cut, where to simplify, and when to push back. That part is still yours.

What you'll do

• Run discovery for your product area: talk to customers, dig into the problem, map workflows, and decide what’s worth building before committing to a build.
• Become a domain expert for your part of the product, with a strong understanding of users, workflows, constraints, and business goals.
• Choose the right tool for each question: proper research when it warrants it, session data or support insights when that’s enough, and a fast prototype when that answers it sooner.
• Own user flows, interactions, and interfaces from first discovery through to shipped product.
• Design for expert users doing complex work, making powerful workflows feel clear, fast, and simple enough to use every day.
• Talk to users directly through client calls, support tickets, and session data, and form product opinions from what you find.
• Work hands‑on with engineers through the build, not just at handoff.
• Use AI tools, including Claude Code, to design, prototype, and iterate. Build your own small tools when that’s faster.
• Contribute to product strategy and roadmap with your PM and the rest of the team.
• Help shape our design system and how design works at SeenThis while both are still taking shape.

Qualifications

• Have 5+ years of product design experience, with the seniority to own complex work from discovery through shipped product.
• Start with the problem, not the screen, and have shipped work where discovery shaped the outcome.
• Have designed complex digital products end to end, with work you can walk through and explain.
• Have a portfolio that shows clear thinking, polished UI, and real outcomes rather than well‑composed screens.
• Move fluidly between early discovery, rough prototypes, high‑fidelity execution, and hands‑on iteration with engineers.
• Treat prototyping as a way to think, test, and align, not just a deliverable to produce.
• Already work AI‑native, with real opinions about where Claude Code or similar tools help and where they get in the way.
• Are a designer who builds, not one who hands off.
• Are solid across UX, interaction, IA, and visual design, with the technical curiosity to understand how the product behaves, not only how it looks.
• Bring high ownership and low ego, and can drive your own work forward while the team and product are still forming.
