Company Overview

Avantos AI is shaping the future of client relationship management by reimagining it through the lens of artificial intelligence. We are building the industry’s first AI-native operating system for financial services, transforming how firms onboard clients, deliver advice, and manage critical servicing workflows. Our platform consolidates fragmented data, automates complex processes, and embeds intelligent decision-making throughout every stage of the client lifecycle.

Supported by Bessemer Ventures and MIT’s investment arm, our team comprises execution-focused, design-driven, product-centric founders and leaders from Wharton, MIT, top design programs, and unicorn SaaS companies. We move swiftly, tackle deep industry challenges, and build technology that empowers users to take charge of their workflows.

If you thrive on client impact, innovative product design, and tackling complex problems, Avantos is the place for you.

About the Role

Imagine owning the design system that defines what excellent looks like across an AI-native platform reshaping financial services, and setting the craft bar for the whole team through it. As Principal Designer, you'll own the Avantos design system end-to-end and lead design on our core product surface, the Agent Portal. This is a senior individual-contributor craft role, not a people-management one. You'll be the craft anchor: the person who decides what good is, builds the system that scales it, and raises the bar for every designer around you.

Design here is moving fast. Our designers prototype in code and build their own AI tooling, and we re-evaluate how we work every few months as new capabilities land. That churn is deliberate, and for the person in this seat it is an invitation: you will help decide how design works at Avantos, not inherit a settled process. What we hold constant is what we value: judgment, taste, and a system that keeps quality high as the team and product scale. When anyone can generate a passable screen in minutes, those are the scarce things, and building them into how the team works is the heart of this role.

Responsibilities

As a Principal Designer you will

Own the Avantos design system end-to-end: component library, design tokens, pattern language, and the contribution rubric that keeps it coherent as the team grows

Set craft direction across the design team through the system, so the bar lives in shared patterns and tenets rather than in one person's head

Lead design on the Agent Portal, our most-trafficked surface and the place where the system ships first and gets pressure-tested in real product work

Author and evolve our design tenets, partnering with the Head of Design to codify what design means at Avantos

Develop the designers around you through critique, mentorship, and modeling rationale-driven thinking

Represent design in cross-functional product and client conversations where senior craft judgment is needed

Minimum Qualifications

8+ years of product design experience, with craft leadership that reaches beyond your own projects; you've moved the bar at a company, not just shipped strong individual work

Deep expertise in product design fundamentals: interaction, information architecture, visual craft, and the systems thinking that turns a component library into a governing design system

A track record of authoring design systems, tenets, or patterns that other designers adopted and built on

Mastery of Figma and the judgment to evolve a design system as a living set of patterns, not a frozen kit

Fluency prototyping in whatever medium fits the question, increasingly in code and with AI rather than only in a design tool

A genuine curiosity, bordering on obsession, about how AI is changing the nature of design, software, and how teams work

Comfort operating as a senior IC and craft anchor without needing a manager title; this role leads through craft and the system, not through reports

Fluency in B2B SaaS or fintech complexity; financial services experience is welcome but not required
