Senior UX Designer

OnRamp transforms B2B customer onboarding into a revenue driver. Our platform automates workflows, streamlines playbooks, and accelerates time-to-value, helping enterprises reduce onboarding time by up to 70%. Backed by leading investors (we just raised our $15M Series A) and trusted by Fortune 15 companies, we’re redefining how companies bring new customers online.

We’ve built the system of record for post-sale workflows, powering onboarding and expansion for enterprise customers including Fortune 15 companies. Now we’re evolving that foundation into something much bigger: an intelligent system that actually does the work.

We’re building an agentic platform that eliminates friction in the B2B customer relationship.

This is OnRamp's first dedicated UX design hire. You'll own the end-to-end design function across the full product — the internal application used by our customers' teams and the external portal experienced by their end customers. A major focus of this role is shaping how AI-powered experiences come to life in the product,as well as owning the end to end user experience.

You'll work directly with the Head of Product and a small, high-output engineering team. There is no existing design team or established design system to inherit — you'll be building the foundation. This is a high-autonomy role for someone who thrives in ambiguity, moves fast, and cares deeply about craft.

• Own UX across the full OnRamp product — internal app, customer portal, AI features, and integrations.

• Design AI-native experiences: agent interfaces, human-in-the-loop patterns, & key AI interaction points.

• Establish OnRamp's design foundation — patterns, components, interaction standards.

• Partner closely with Product and Engineering to go from problem framing through shipped work, often in compressed timelines.

• Conduct user research to inform design decisions and validate direction.

• Create flows, wireframes, prototypes, and high-fidelity mocks. Contribute to front-end implementation when it accelerates delivery.

• Champion usability and coherence across a product that spans complex B2B workflows, configuration surfaces, and a consumer-grade portal experience.

• 7+ years of product design experience in B2B SaaS, with a portfolio that demonstrates strong interaction design and systems thinking.

• Experience designing AI-powered or intelligent features — you understand the unique UX challenges of non-deterministic systems, progressive disclosure of automation, and building user trust in AI.

• Comfort operating as a solo designer embedded in a product and engineering organization. You don't need a design manager or a mature design ops function to do great work.

• Strong opinions on craft, loosely held. You care about details but adapt quickly when context changes.

• Ability to work across the full design stack — research, strategy, interaction design, visual design, and light prototyping or front-end contribution.

• Excellent communication skills. You can articulate design rationale to engineers, product leaders, and executives clearly and concisely.

• Experience with Figma (or equivalent) and familiarity with component-based UI frameworks (Vue, React, etc.) is a strong plus.

• Experience in customer onboarding, implementation, customer success, or adjacent post-sale workflows.

• Background designing multi-persona products (internal users + external end customers).

• Familiarity with design systems built on top of libraries like PrimeVue, Vuetify, or similar.

• Prior experience at a Series A–C stage startup where you helped define the design culture from scratch.

• First UX hire — you'll shape design at OnRamp from the ground up.

• AI-forward product roadmap — OnRamp is building agentic AI into the core product, not bolting it on. You'll design the interfaces for that future.

• High leverage — small team, direct access to leadership, fast shipping cadence, and real customer impact.

• Complex, interesting problems — B2B workflow automation, multi-persona experiences, and the challenge of making powerful software feel simple.

• Work directly with enterprise and mid-market clients, including Fortune 15 companies

• Join a high-growth AI-first company that just raised its $15M Series A led by top investors

• Be part of a collaborative, ownership-driven culture

• Highly competitive cash compensation, equity, and benefits

• Boston-based, 3+ days a week in-office
