UI/UX Designer - Freelance / Part-Time

Who are we?

Finance teams need clear visibility into their cash flow, but most still rely on Excel to manually track data across multiple bank accounts. This makes it hard to see real-time cash positions, spot trends, and drive smarter financial decisions.

Nilus changes that.

We're building an AI-powered cash management platform that gives finance teams real-time cash visibility, forecasting, and reconciliation—all powered by AI, eliminating manual work and unlocking insights that help businesses grow.

Backed by top VCs including Bessemer, Felicis, BTV, and Symbol - Nilus is a fast-growing fintech startup led by a team of ex-fintech pros passionate about transforming the finance function.

What We’re Looking For:

We’re looking for a freelance/part-time UI/UX Designer to help shape intuitive, scalable experiences across complex B2B workflows.

What you’ll be doing

Design clear, intuitive experiences for multi-step treasury workflows (payments, reconciliation, approvals, cash visibility, etc.).
Work closely with Product and Engineering to turn requirements into user journeys, wireframes, prototypes, and high-fidelity designs.
Design and refine AI-powered experiences, including chat-based flows, assistant interactions, and automated decision workflows.
Create demos, interactive prototypes, short product videos, and visuals that communicate complex financial concepts simply.
Collaborate on marketing collateral that showcases Nilus’ product value-automation, visibility, and operational efficiency.
Contribute to and evolve our design system to ensure consistency across dashboards and interfaces.
Operate in a startup environment where speed, clarity, and cross-functional collaboration are essential.
