What you'll be part of
Circle is committed to visibility and stability in everything we do. As we grow as an organization, we're expanding into some of the world's strongest jurisdictions. Speed and efficiency motivate our success, and our employees live by our values: High Integrity, Future Forward, Multistakeholder, Mindful, and Driven by Excellence. We've built a flexible work environment where new ideas are encouraged and everyone is a stakeholder.
At Circle, we're moving from a phase of rapid expansion to one of sophisticated scale. As blockchain adoption grows, the systems that power our products - and the economic activity they enable - need to mature with intention, clarity, and trust.
We're looking for a Lead Product Designer to join the Arc pillar. This role focuses on shaping how developers and businesses interact with blockchain-native products and primitives - including networks, transactions, permissions, and programmable value. Rather than designing isolated features, you'll work across products and teams to define experiences that make blockchain infrastructure usable, reliable, and economically meaningful.
We're looking for a designer who understands blockchains as more than technology as systems that shape incentives, ownership, and value flow. You should be comfortable reasoning about how design choices influence trust, behavior, and participation in crypto ecosystems, while still holding a high bar for craft and usability.
What you'll work on
Blockchain-native experiences: Design workflows and interfaces that expose the power of blockchains - such as transactions, permissions, programmability, and settlement - in ways that feel understandable and intentional.
Economic clarity: Help users reason about value flow, costs, and tradeoffs (e.g. fees, execution, finality) without overwhelming them.
Cross-team alignment: Partner with Product and Engineering leaders to define priorities and make tradeoffs across blockchain protocols, platform surfaces, and downstream products.
Systems and patterns: Identify repeatable models and abstractions that can scale across blockchain use cases and products.
Design leadership: Set direction for complex problem spaces, mentor other designers, and raise the bar for blockchain product design across the organization.
Chain fluency: 7+ years of product design experience, with meaningful exposure to crypto, blockchain, or financial infrastructure products. You understand how blockchains work at a conceptual level and why they matter.
Comfort with complexity: Strong ability to design across interconnected workflows that involve technical and economic tradeoffs.
High craft bar: Excellent interaction and visual design skills, applied in service of clarity, trust, and correctness.
Design leadership: Experience setting design direction, influencing cross-functional partners, and mentoring designers.
Clear communication: Ability to explain complex ideas, articulate design decisions, and collaborate effectively in a distributed environment.
Circle is on a mission to create an inclusive financial future, with transparency at our core. We consider a wide variety of elements when crafting our compensation ranges and total compensation packages.
Starting pay is determined by various factors, including but not limited to: relevant experience, skill set, qualifications, and other business and organizational needs. Please note that compensation ranges may differ for candidates in other locations.
Base Pay Range: $172,500-$225,000We are an equal opportunity employer. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status, or any other protected status required by the laws in the locations where we hire. Additionally, Circle participates in the E-Verify Program in certain locations, as required by law.
