Senior Product Designer

Pact Fi Design Problem The product is moving from a screen-first build model, where the underlying system is designed first and the interface follows. Today's product is fully deterministic, human-driven screens. You'd help define, from scratch, what this platform looks like as AI becomes a first-class part of it — AI agents as a new type of participant alongside human users, and AI as a new interaction modality for human users themselves. Workflows are tied to assets that can live 5–7 years, resurfacing repeatedly at different cadences over that lifetime, with multiple parties holding different views and permissions each time. Clients regularly bring new deal and asset structures the platform hasn't seen before, so the product has to accommodate structural variation it can't fully anticipate. Permissioning is layered — participants often have their own downstream stakeholders who need visibility into a subset of the same information. A point of view on how AI is reshaping what a "product" is — where a great interface is still needed versus where the underlying data itself, exposed well, is becoming the product — is a plus. What You'll DoOwn one or two major product surfaces end-to-end — from problem framing through shipped, polished detail. Design and ship the platform's first real AI-native interaction pattern in an otherwise fully deterministic product — no existing pattern to extend from. Design for dense, structured financial data at scale, and for multi-party, long-running workflows with layered permissions. Work closely with the PM and engineers on your surface to develop the strategy and rationale behind what you build, not just execute a spec. Contribute to and help shape a design system built for extensibility across evolving workflows and asset structures. Set an example in critique and day-to-day work for how design is done here — the work itself is the signal, not a title or mandate. What You Should Have Prior experience in product design roles shipping software to users, working closely with cross-functional teams on the strategy and rationale for features, not just executing handed-off specs. Real, hands-on experience designing AI-native interaction patterns, or clear fluency and specific examples of exploring them — not just general enthusiasm. Comfort designing for dense, data-heavy interfaces, not just typical consumer-style layouts. An outstanding portfolio with case studies showing typography, interaction, and visual design craft, plus product sense and idea generation. Comprehensive experience using prototyping to explore and convey design solutions. Excellent written, verbal, and storytelling skill. What We Offer Competitive salary + equity.
