Job description

Company Description

We're building
Key Space
, an AI-driven SaaS platform for
warehouse and inventory optimization
.

Our mission is to give small and mid-sized warehouses the kind of real-time visibility and analytics usually reserved for enterprise WMS systems — but in a modern, accessible, cloud-based product.

Our MVP is live and functional.

Now, we're looking for a
Senior Frontend Engineer
to help us push it over the finish line — making it faster, more reliable, and production-ready.

Role Description

We are seeking a
Senior Frontend Engineer (React + TypeScript)
to join us on a contract basis and help bring our SaaS MVP to production quality.

The role is focused on
optimizing our existing React architecture
— enhancing custom hooks, streamlining context/state management, and ensuring performance at scale for data-heavy dashboards.

You will work closely with the founder/technical lead to:

  • Optimize custom hooks
    for performance and stability
  • Improve
    context providers
    to reduce re-renders and add selectors
  • Unify filtering/search
    across orders, inventory, and products (smart filters, presets, autocomplete)
  • Implement
    dashboards & data visualization
    (Recharts/D3, drill-down metrics, trend analysis)
  • Virtualize long tables
    and add progressive loading states
  • Enhance
    UX polish
    (skeleton loaders, toast notifications, mobile-friendly layouts)
  • Implement
    permission-aware UI
    with role-based guards and clear fallback states
  • Standardize
    export/import flows
    (CSV, Excel, PDF)

Qualifications

  • 4+ years of professional React development (enterprise/SaaS apps preferred)
  • Expert in
    TypeScript
    (generics, discriminated unions, API typing)
  • Strong with
    Vite + Tailwind + Axios
    integration
  • Experience with
    context/state optimization
    (React Query-like patterns a plus)
  • Skilled in
    performance optimization
    (virtualization, memoization, bundle optimization)
  • Dashboard and analytics experience (tables, charts, filters)
  • Testing background (Vitest + React Testing Library)
  • Bonus: prior experience with
    inventory, logistics, or warehouse management systems

Engagement Details

  • Type:
    Contract (Remote)
  • Duration:
    10–12 weeks (medium scope, milestone-based)
  • Hours:
    ~20–25 hrs/week
  • Compensation:
    $30–$45/hr depending on experience and region
  • Start Date:
    ASAP
