About the project

We're looking for a UI/UX designer to redesign the configuration menu of an existing 3D product configurator. The configurator is used by clients to visualize and customize furniture/outdoor product lines in real time. 
 

https://www.tuuci.com/designstudio/
 

Current State

The existing menu is outdated, unnecessarily complex and creates usability challenges due to limited guidance for new users. It can also prevent the team from introducing new features. The current main goal for customer is to configure each product on the scene individually, rather than product composition as a whole, which can’t be done with the current menu set up.

Scope of Work

• Audit of the current configurator UX/UI (we will provide details on main pain points and any context that needed)
• User flow mapping for the new "configure by element" experience
• Wireframes and interactive prototypes
• UI design aligned with existing brand guidelines

• Design handoff documentation for development (specs, states, edge cases)

   

Deliverables

• UX audit summary
• User flow diagrams
• Wireframes (low-fi)
• Interactive prototype (e.g., Figma)

• Final high-fidelity UI designs, including all component states (default, hover, selected, disabled, error)

   

What we're looking for

• Strong portfolio in configurator, e-commerce or product customization UX 
• Experience designing complex interfaces 
• Comfort working with 3D/visual product data and real-time preview systems
• Ability to simplify complexity without removing functionality
• Familiarity with component-based design systems
• Strong communication skills (a collaborative process with our internal team and stakeholders)

Apply now and let’s grow together.

EducateMe is an AI-native learning platform for growing US companies. We're hiring a growth operator to own a new acquisition channel: AI search.

You'll be measured on the number of SQL, not articles.

When a buyer asks ChatGPT, "what's the best LMS for a 200-person behavioral health company?" — your job is to make sure EducateMe is in the answer. That's the whole role: owning how AI assistants see, describe, and recommend us.

This is not a content manager position. Content production is ~30% of the job, and even that part is operating our AI content engine (Claude-based pipeline): prompting, editing, injecting real customer specifics, shipping. Nobody here writes articles from scratch since we operate the AI-powered content engine

What you'll own:

The channel and its number. Your KPI is AI-attributed demos/month, with citation share on our target prompt set as the leading indicator.

1. On-site assets — run the AI content engine: comparison and alternative pages, pricing content, question pages, case studies. You maintain the money pages that AI assistants cite.
2. Off-site presence — manage the Reddit agency relationship, pitch industry listicles (eLearning Industry and similar), own our G2/Capterra profiles and the review pipeline (with our CSM), keep the YouTube listing-video cadence running.
3. Measurement — monthly money-prompt tracking across ChatGPT, Claude, Perplexity, and Google AI Mode; demo attribution analysis; a monthly "what moved and why" readout to the founder.
4. Sales enablement spillover — case studies, one-pagers, and snippets flowing to our outbound SDR and founder-led deals. The same assets serve both.

Requirements

• AI-native. Daily user of ChatGPT/Claude — you have an intuition for how AI assistants compose answers and pick what to recommend.
• Channel ownership experience. You've run a growth channel to a measurable result: traffic, leads, revenue. Any channel counts, including your own project (a site, a community, a Telegram channel you grew).
• Data-comfortable. You read analytics without hand-holding and find answers in data yourself.
• Strong written English (C1). Editing and judgment matter more than prose.
• Generalist mindset. Content, community, and measurement in one role: you switch between them daily.
• B2B SaaS experience is a plus, not a must.
   

What this role is NOT:

• Not a classic content manager or copywriter — we don't need article volume
• Not classic SEO — link building and keyword rankings aren't the game
• Not an agency strategist — no strategy decks, hands-on execution only

Format

• Full-time, remote
• You report directly to the founder and work alongside a small senior team (product, engineering, customer success, outbound)

🚀 We're Hiring: CRO Specialist / Funnel Manager

We're a high-volume performance marketing company — and we're looking for someone who is obsessed with conversion data and knows how to act on it fast.

This isn't a "build pretty pages" role. We need a ruthless optimizer. Someone who lives inside tracker dashboards, runs aggressive A/B tests, and knows exactly when to cut a losing funnel and scale a winner.

What you'll own:
→ Daily management, setup, and optimization of landing pages, offers, and traffic flows inside Keitaro (or equivalent trackers like Voluum / Binom)
→ Formulate hypotheses, launch split tests (headlines, layout, CTA, angles), and decisively cut losers while scaling winners
→ Work directly with media buyers — align funnel adjustments with incoming traffic sources, angles, and target audiences
→ Feed performance data and market trends back to copywriters and designers to brief high-converting creative assets
→ Monitor core KPIs (CTR, Conversion Rate, ROI, CPA) and translate raw data into strategic creative briefs

You're the right fit if you have:
✅ Hands-on experience with Keitaro (highly preferred) or equivalent self-hosted/cloud affiliate trackers — redirect rules, lander protection, and postbacks are second nature to you
✅ A background in direct-response marketing, affiliate marketing, or high-volume media buying (brand marketers or corporate UX designers — this role is not for you)
✅ True data literacy — you can open a tracker dashboard or spreadsheet, spot statistically significant trends instantly, and make decisions without hand-holding

Bonus points if you have:
⭐ Basic front-end skills (HTML / CSS / JS) to make quick landing page tweaks without waiting on a developer
⭐ Experience with spy tools (Adspy, Anstrex, or similar) to track competitor funnel trends

Comp: Base salary + performance-based commission

If you've diagnosed a sudden campaign drop, rebuilt a funnel from scratch, or turned a losing angle into a winner with data — we want to talk.
