About the Company

We're building INKHUB, an AI-powered discovery engine for 1M+ high-quality marketing assets.

Think of it as the semantic search layer for B2B content—structured, searchable, and always fresh.

Design and operate a raw document crawler and freshness scheduler (S3 + SQS or EventBridge / Lambda).

Extend Flask APIs to support: Page claiming and editing

SSO sign-in with Google / LinkedIn or magic links

Role-based access control and usage tracking

Finalize the React (MUI) admin dashboard with asset review, user roles, and usage analytics.

Wire our FastAPI semantic search service into the UI (type-ahead, filters, snippet previews).

Enforce SEO best practices: structured URLs, sitemap generation, s, and redirects.

Harden CI / CD with GitHub Actions (or Jenkins); deploy via Helm to AWS (EKS or ECS).

Add lightweight bot-protection (rate limits, IP whitelisting).

Monitor latency & error budgets via CloudWatch and Grafana.

Our Stack

Python (Flask + FastAPI), PostgreSQL, Redis, React (TypeScript + MUI)

Docker, Helm, AWS (S3, Cognito / Auth0, EKS), OpenAPI3

GitHub Actions, Jenkins, SQS, EventBridge or Celery
