Timezone: 4+ hours daily overlap with EST

Direct Hire – Product Company (NOT outsourcing)

About Us:

Kennel Connection is a US-based SaaS company serving pet care businesses. We are a product company, not an agency — we own and develop our software in-house and are building a long-term team.

Role Overview:

We are looking for a UI/UX Designer who can also implement their designs using HTML, CSS, and jQuery. This is a design-first role: your ability to create clean, user-friendly layouts is more important than your ability to write complex JavaScript. We work in a classic stack — no React, no Angular.

What You’ll Do:

• Design user interfaces and flows for our web-based product
• Create wireframes, mockups, and final UI assets
• Implement your designs directly in:
  • HTML / CSS / SCSS
  • jQuery
  • Razor (.NET view engine)
• Collaborate with product and engineering teams
• Gradually help modernize and improve the overall UX

What We’re Looking For:

• 3+ years of UI/UX design experience
• A portfolio showcasing web app design work
• Ability to implement layouts in HTML/CSS/jQuery
• Comfortable working in an older codebase (no React/Angular)
• Strong attention to UX detail and usability
• English level B2 or higher
• Looking for a stable, long-term role

We Offer:

• Long-term role in a growing SaaS company
• Full ownership of UI/UX across the product
• Friendly, collaborative team
• Salary growth based on impact
• Flexibility and stable working hours

• Feature Ownership: Taking a task from a Jira ticket to a production-ready feature through code reviews and CI/CD.

   

What’s in it for you (Perks & Benefits):

• Single Product: No outsourcing. You work on one codebase and see the long-term results of your decisions.
• Support: You’ll have a lead to consult with and a clear plan for your next salary/level review.
• Lviv & Remote: We have a modern office in Lviv (with paid lunches), but you’re free to work from home.
• High-End Tech: We provide a powerful laptop and any extra equipment you need.
• Rest: 18 vacation days + 10 personal days off + 5 sick leaves.
