ABOUT THE OFFER
This is not a full-time job but rather part-time to one-off for creating designs for the product.


ABOUT THE PRODUCT

We are building the accounting software that accounting firms run their daily work on. The user is a professional who spends hours in front of this screen and repeats the same operation hundreds of times a day.

This is different from designing a marketing site or a consumer app. The product's core screens are data entry, tables, filters and multi-step operations. We want an interface that looks current and feels considered, but the real measure is how many seconds and how many mistakes it takes an experienced user to record an invoice.

We are not building another generic dashboard. Most accounting software looks and behaves the way it did fifteen years ago, and that is exactly the gap we're going after.

We are currently in the pre-coding phase. Business rules are being written by our domain expert, and screens will be designed and approved before they are built. The designer is part of this process, not something that happens at the end of it.

WHAT YOU'LL DO

- Design the product's core screens and user flows: invoice creation, customer accounts, chart of accounts, journal entry, period-end operations, reports
- Map the flows before the screens: what the user is trying to finish, where they enter, what they see at each step, and where things can go wrong
- Build fast, keyboard-first, low-click flows for users doing heavy data entry
- Design layered interactions deliberately: decide what belongs in a full page, a slide-over, a modal or a popover, and keep those choices consistent across the product
- Create a reusable component library, design system and written guidelines: tables, forms, filters, notifications, modals, type and spacing scale, and the rules for when each is used
- Design not just the ideal state of a screen, but its empty, error, loading and no-permission states
- Review your designs with the domain expert and catch conflicts with the business rules while they are still in design
- Hand off designs a developer can implement without asking questions: dimensions, states, behaviors and exceptions defined

WHAT WE'RE LOOKING FOR

- At least 3 years designing B2B, internal or data-heavy products
- Experience designing complex table and form screens
- A current visual sensibility: familiar with where interface design is today and able to apply it to a dense professional tool without turning it into decoration
- You treat UX as seriously as UI. A screen that looks good but adds a step to the user's day is not a finished design
- Experience with user flows and with writing the guidelines that keep a product consistent as it grows
- Comfort with multi-layer interactions and nested flows: slide-overs, modals, popovers, and knowing when not to use them
- Fluency in Figma with components, variants and design systems
- The ability to explain why your design is the way it is, and to change it in response to feedback
- You don't need to know accounting, but you do need to be willing to learn the rules of an unfamiliar domain and ask questions

NICE TO HAVE

- Experience in accounting, finance, ERP or another regulated domain
- Experience with accessibility and keyboard-driven interfaces
- Enough HTML/CSS to read it and discuss implementation details with developers

HOW TO APPLY

Apply with your portfolio. What we want to see: complex screens from a real product. Include at least one piece with tables, forms, filters or a multi-step operation.

For one of your pieces, briefly answer these three questions:

1. Who used this screen, and what were they trying to get done?
2. What design decision did you make, and why?
3. How did you know whether it worked?

We can't evaluate portfolios that show only visuals with no reasoning behind the decisions.

PROCESS

1. Intro call: the product and how we work
2. Portfolio: you walk us through one piece and the decisions behind it
