Our team is all about straightforward communication, embracing feedback without taking it personally, and fostering a super collaborative environment. It’s a sports team that’s hyper focused on winning, collaborative internally, and competitive externally - never the other way around.

What is this role like？

We’re looking for a creative, hands-on, and cross-functional Design Lead to own and elevate design at Topsort across both product and brand. This role is perfect for someone who can zoom between pixels and systems, detail and direction, and who’s excited to shape the visual identity of a fast-growing adtech company from the ground up.

You’ll set the quality bar, and work directly with product, marketing, and leadership to ensure our user experiences are not only functional, but elegant and cohesive. You’ll guide everything from feature-level UI/UX to brand campaigns and visual storytelling, making sure Topsort looks and feels like the category-defining product we’re building.

This is a high-impact, hands-on role for a designer who’s ready to lead, ship, and scale, and who thrives in early-stage, product-led environments.

You will:

• Lead and evolve Topsort’s design function, spanning both product UX and brand design
• Work hands-on in Figma to create intuitive, delightful user experiences for our platform, APIs, and tools
• Define and maintain a cohesive design system that balances speed, scalability, and craft
• Mentor and support a small team of designers, fostering collaboration and growth
• Collaborate cross-functionally with product, engineering, marketing, and go-to-market teams to align design decisions with business goals
• Translate complex concepts (auctions, APIs, data flows) into clear, user-friendly interfaces and communications
• Shape and refine Topsort’s visual identity across touchpoints—from the app to the website to event collateral
• Balance speed with precision, making smart trade-offs in a fast-moving, startup environment
• Champion design quality and usability, helping the team think in systems, not just screens

What (we think) you need to be successful - we’re open to not checking all the boxes and be proven wrong by outlier candidates as well! 

• 6+ years of experience across product design and brand/visual design, with a strong portfolio that demonstrates both
• Experience designing and shipping complex digital products, ideally in B2B, SaaS, or technical domains
• Comfortable working with and leading a small team, including mentoring, direction-setting, and feedback
• Fluent in tools like Figma and comfortable owning systems, prototypes, and design documentation
• Strong understanding of interaction design, layout, and visual hierarchy
• Able to think and speak cross-functionally, working with engineers, marketers, and execs alike
• A builder’s mindset: you seek feedback, move quickly, and focus on delivering impact
• A passion for clarity, simplicity, and polish in every design decision
• Excitement about owning a zero-to-one design journey and influencing company-wide aesthetics and UX
• Been located in Boston and available to work onsite from our Somerville office 4 days a week onsite.
