Nahmani Group · PropTech / FinTech platform, US market

Category: Design → UI/UX | Seniority: Middle | English: Intermediate+ | Part-time, fully remote

About us

Nahmani Group (nahmanigroup.com) is a US-focused PropTech platform for real estate developers and investors. In one place we help them find off-market deals, run a full underwriting analysis (ARV, repair estimate, profit, ROI), send LOIs, manage the pipeline in a built-in CRM — and, most importantly, raise capital for a deal through a dedicated investor page for each property.

The product is live and growing. We're a small team, so your designs  ship fast — usually within days, not quarters.

What you'll be designing

Deal analysis screens — data-dense tables, property cards, comps, underwriting breakdowns.

Think PropStream, but clearer.

Property investor pages — public landing pages that raise capital for a specific property. Trust, clarity and conversion are everything here.

CRM — pipeline, deal stages, tasks, communication history.

Dashboards and reports for developers, investors and (later) lenders.

Design system — components, tokens, states, mobile/desktop, so the product stops looking assembled from parts.

What we're looking for 2+ years in product design (web apps, not only landing pages)

Strong Figma: auto-layout, components, variants, tokens, prototypes

Experience with data-heavy B2B interfaces — tables, filters, charts, dashboards

Ability to design responsive layouts and hand off clean, dev-ready files

You think about states: empty, loading, error, long text, 300 rows of data

English Intermediate+ (product and users are US-based; team communication can be in Ukrainian)

Portfolio required — we care about how you think, not only about the shots

Nice to have

Experience in fintech, proptech, real estate, investment or analytics products

Understanding of basic HTML/CSS constraints (you don't need to code)

Experience designing landing pages that convert

Familiarity with AI-driven product interfaces

How we work

Part-time, ~20 hours/week, flexible schedule

Fully remote

Direct communication with the founder — no design-by-committee•

Fast feedback loops and real influence on the product

Hiring process

1. Short intro call (~30 min)

2. Portfolio walkthrough — you show 1–2 cases and how you solved them

3. Small paid test task (one real screen from our product)

4. Offer

Please include a link to your portfolio in your application and tell us in 2–3 sentences which data-heavy interface you're most proud of and why.
