About the role

What Makes this Role Different


Most AI products help individuals save minutes. Stacksync helps companies run their operations. Our enterprise AI is built on years of expertise in connectors, syncs, and workflow orchestration, allowing businesses to automate the processes that directly impact e-commerce, supply chain, logistics, operations.
Under the hood, the product handles deep technical infrastructure: asynchronous jobs, data mappings, approvals, errors, retries, and multi-system orchestration.
Your job is to make that complexity disappear.

What you will do:

  • Design and build polished frontend experiences for enterprise AI agents and workflows.
  • Translate complex backend states into simple, predictable user flows. You will dive deep into our backend capabilities to truly understand how our AI agents work, and then distill those complex flows into frictionless user journeys.
  • Partner directly with the founders to turn prioritized product directions into polished frontend experiences, owning the UX details, interaction design, frontend architecture, implementation, and iteration.
  • React + IBM Carbon components.

You might be a great fit if:

  • You are a senior frontend engineer, with exceptional UX instincts and product taste.
  • You can understand complex technical systems and turn them into simple product experiences.
  • You are comfortable working without perfect specs and can make strong product decisions independently.
  • You move fast, communicate clearly, and care deeply about attention to details.
  • You care about hierarchy, loading states, empty states, error states, edge cases, and micro-interactions. This is an Enterprise product, not a vibe coded UI full of bugs.
  • You have experience working with these enterprise systems (CRM, ERP, etc)
