Senior Frontend UX Engineer

About
Hubs

At Hubs, we're building the intelligence layer for organizations — where anyone can build AI solutions that spread and compound across the org. Our team is growing, fast-moving, and ambitious — led by multi-exit Silicon Valley entrepreneurs with a strong track record of creating products that shape how people work.

Along the way, we get to work with some of the most exciting parts of technology today — autonomous AI, innovative UIs, and reactive dataflows. It's the kind of work where the engineering itself feels fresh and creative, with room for invention and curiosity.

Joining Hubs means working on problems that matter. You'll be building for yourself, your peers, and millions of professionals navigating the shift from pre-AI to AI-first work. The products you create will be visible, widely used, and part of a broad societal transformation in how knowledge work gets done.

About
the Role

You
will play a key role in shaping how users feel when they
interact with our product. As part of the UX design council,
you'll need to think deeply about collaboration, complex
interactions, and how to make a powerful tool feel simple
and delightful. This highly collaborative role is ideal for
someone who doesn’t just “implement specs” but actively
improves them, anticipating user needs and sweating the
details that make an interface feel polished and intuitive

• Lead
  the end-to-end implementation of user-facing features,
  from concept to release.
  

• Translate
  design ideas into seamless, performant, and accessible
  experiences.
  

• Work
  closely with product management, design council, and
  backend team to ensure interactions are both elegant and
  technically sound.
  

• Bring
  attention to detail and polish — raising the bar and
  reducing rework by getting things right the first
  time.
  

• Help
  shape best practices for frontend development in a
  growing, ambitious team.
  
  

Requirements

• Expert-level
  proficiency in React (and ideally Next.js or similar SSR
  frameworks).
  
• Strong
  background in real-time applications (WebSockets,
  CRDTs/OT collaboration patterns).
  
• Deep
  experience with CSS architecture, animation libraries,
  and building pixel-perfect UIs.
  
• Familiarity
  with performance optimization (lazy-loading,
  memoization, bundle optimization).
  
• Strong
  grasp of accessibility standards (WCAG) and responsive
  design principles.
  

• Passion
  for creating experiences, not just interfaces — you
  empathize with users and design for ease of use vs.
  power tradeoffs.
  
• Ability
  to simplify complex workflows into elegant, intuitive
  interactions.
  
• Obsessive
  attention to micro-interactions, motion, and polish —
  you notice when a pixel is off or a transition feels
  wrong.
  
• Aesthetic
  sense for color, typography, and spacing that builds
  user trust and delight.
  
• Experience
  with collaborative or interactive apps (e.g. Figma,
  Notion, Miro, Google Docs-like systems).
  

• A
  proactive, “product-first” approach — you challenge
  specs when they don’t feel right and propose better
  solutions.
  
• Comfortable
  with ambiguity and excited to co-create features, not
  just build tickets.
  
• Strong
  communication skills and ability to collaborate with
  designers, PMs, and backend engineers to ship quickly
  without sacrificing quality.
  
• A
  builder at heart — self-directed, curious, and eager
  to ship beautiful, impactful features.
  
• Committed
  to shaping and scaling best practices for frontend
  development and design systems as the team
  grows.
