Product Designer UI/UX/AI

About Flexspace AI

• Flexspace AI is the e-commerce + AI revenue platform for coworking - / Shopify / Airbnb for flexible workspace. Seed-funded. We turn operators' websites into high-converting storefronts and run AI agents that price and market their inventory in real time.
• What we ship: mobile-first booking engine that embeds in any operator's site; SmartPricing Agent for dynamic pricing on meeting rooms, day passes, offices; SmartMarketing Agent for promo campaigns; operator dashboard for revenue/bookings/attribution; member portal for end customers; two-way integrations with prominent property management systems.
• Who buys it: coworking operators from single-location indies to multi-country brands. Their revenue is the conversion rate of the screens you'll design - CTAs, catalog, transitions, and checkout aren't decoration here; they're the product.
• How we work: small, agile, AI-heavy. On track to profitability this year. Headcount is deliberately small so each person owns real surface area - tight feedback loops, no bureaucracy, no committees. We measure shipped work - funnel lifts, partner themes shipped, UX issues triaged - not hours. No face-time theater.
• Co-located hybrid out of Workflow Thao Dien in HCMC for in-person speed. Wider team is async-first, written-first across US, Israel, Turkey, Philippines, and Vietnam. Weekly product/design sync with the CTO/cofounder - no layers between you and the people deciding what to build.

The Role

Product Designer across our three products: Operator Dashboard, eCommerce customer-facing pages, and Member Portal. You report to the CTO (also a cofounder). No design layer above you.

• What design means here. The hard problem isn't decoration - it's information. Operators juggle hundreds of spaces, prices, members, bookings, integrations, and promotions across locations and timezones. Customers comparing meeting rooms decide in seconds. Members need to find what they're entitled to without reading docs. Your job is to sit with these humans - on calls, in onboarding, over recordings - and reconstruct the mental model they're operating under, including the frustrations they've stopped voicing. Then decide what surfaces when, what's grouped, what's hidden until needed. Empathy is the input; information architecture is the output. Visual polish comes last.
• On prioritization. Not all UX work has the same payoff. You'll look at the same problem from multiple angles - funnel data, operator interviews, revenue, churn signals, support tickets - and pick the surface where your hours move the business most. A polish pass on a screen no one reaches is wasted hours; a 2% lift on the booking funnel is the company's quarter. Judgment over completeness.
• On UX decisions. Bigger calls go to the team before execution. Smaller calls - ship, watch the data, iterate. We're data-driven, not opinion-driven. Real authority over the surfaces you cover; expose your reasoning so we can calibrate together.
• Design system. You're inheriting a partial foundation - it exists, it works, the bones aren't perfect. Today's concrete bottleneck: the system isn't documented well enough for Claude to pick the right component. Closing that gap is core to the role. We also need a north star for where this design system and product experience should be in 12-18 months.

What You'll Do

• Audit, watch the funnel across all three apps. Surface obscure UX issues - flows, transitions, empty states, error states, micro-copy.
• Prototype UI/UX adjustments constantly. Most can be driven with AI if you can guide the frontend correctly.
• Theme partner storefronts. Take a partner's brand (logo, fonts, palette, tone) and tune our eCommerce surfaces to feel native - including non-Latin scripts (Hebrew RTL, Polish diacritics, Spanish, English).
• Recommend CTA placements on partner marketing sites - where, what they say, how they look - to maximize the funnel into our checkout.
• Pull data, form an opinion, decide. Revenue, Mixpanel, GA4 / GTM funnel data, operator feedback.
• Make the design system AI-legible. Each pattern - empty state, error, modal, form, badge, toast - named, exemplified, discoverable from a prompt. Codify repeating patterns as reusable components, documented heuristics, or prompt templates.

How You'll Work With AI

Claude as a peer, not a novelty. You'll iterate on structured prompts and build new ones. Engineers coach you and set guardrails so you can ship UI changes through Claude without first becoming a framework expert. Taste, intent, and judgment are the bottleneck now - not syntax.

What Success Looks Like In 6 Months

• You own UX critique across Dashboard, eCommerce, and Member Portal.
• Partner theming pipeline is documented, repeatable, faster than today.
• You've shipped frontend tweaks directly into the codebase - not just handed off specs.
• You're driving CTA recommendations on partner websites end-to-end, with measurable funnel impact.

Must-have

• Vietnamese, based in Ho Chi Minh City. Hired on a Vietnamese employment contract. No visa sponsorship or relocation funding.
• Solid UI/UX fundamentals: visual hierarchy, IA, accessibility, error prevention, cognitive load. You can name the heuristic you're applying.
• Human empathy. You can watch users, reconstruct the mental model they're operating under - including the frustrations they've stopped voicing - and let that shape design. User-situation-first, not heuristics-first.
• Information design. You can take a dense, multi-dimensional dataset (bookings x spaces x times x prices x members x policies) and decide what to show, what to hide, what to group, how to layer it.
• Interactive portfolio with at least one full product flow we can click through end-to-end. Live, clickable links - Figma, Framer, Notion, or any platform. State, hover, transitions wired up. No static PDFs or screenshot decks.
• AI-native, Claude-fluent. Daily Claude user, sharp prompter. You know where it shines and where it breaks down.
• Frontend-curious. Willing to ship UI changes into the codebase via Claude with engineer coaching and guardrails.
• QA-grade attention to detail. You spot the obscure flow break, the misaligned state, the off-by-one transition.
• Writing and reading English required for async work. Speaking can be conversational - we coach.
• Agency. You spot things, fix things, ship things - don't wait to be told.

Nice-to-have

• E-commerce, marketplace, or booking-site exposure.
• Conversion / funnel optimization experience.
• Multi-language / RTL exposure (Hebrew, Polish, Spanish) - speeds up partner theming work.

New graduates and self-taught designers are welcome if the must-haves are real. What matters is taste, agency, willingness to ship, and how fast you learn.

This role suits future founders. Direct cofounder access, real ownership of decisions and outcomes, scope across an entire product surface, an inside look at how a small team turns AI into shipped product. If you aspire to build your own startup product one day, this is the seat that builds the muscles.

Compensation & growth

• Salary: 20M - 40M VND/month NET. Calibrated on portfolio strength, interview sharpness, and demonstrated speed of learning, not years on a resume. Exceptional senior candidates can be discussed above this band.
• Comp reviews on request - if you've grown the role, raise it.
• Probation: 2 months at full salary. Passes on shipping consistently + demonstrating taste in critique - no surprise gates.
• Stock options eligibility and a company laptop after probation. Bring your own laptop during probation.

Tools

• Company-paid Claude, Figma Team Plan seat

Workspace & culture

• Covered desk at Workflow Thao Dien (HCMC). Hybrid 2 days/week in-office, bouncing product ideas & solutions.
• Vietnam time (ICT). Occasional pre-scheduled evening calls overseas, rare in practice.
• English-first, American startup culture: direct feedback, written-first, low-meeting. We measure shipped work, not hours.

Benefits

• BHXH / BHYT / BHTN contributions per Vietnamese labor law.
• Vietnamese public holidays off (incl. Tết).
• Unlimited personal time off. Coordinate with the team based on urgency and your ownership.
