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.

What You’ll Do

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

You Might Be a Fit If…

You've shipped or maintained a production‑grade full‑stack app.

You've worked with semantic search, API‑first products, or CMS‑style workflows.

You're comfortable juggling frontend, backend, and basic infra ops.

You care about clarity, performance, and edge‑case handling.

You enjoy being hands‑on and autonomous.

Why This Role Matters

Your work is the platform.

You'll ship and scale the surface where users discover AI‑powered answers, browse the freshest B2B content in the world, and claim their company profiles.
