Jobbeschreibung

Hiring Process

OUR HIRING PROCESS:

• We will review your application against our job requirements. We do not employ machine learning technologies during this phase as we believe every human deserves attention from another human. We do not think machines can evaluate your application quite like our seasoned recruiting professionals—every person is unique. We promise to give your candidacy a fair and detailed assessment.
• We may then invite you to submit a video interview for the review of the hiring manager. This video interview is often followed by a test or short project that allows us to determine whether you will be a good fit for the team.
• At this point, we will invite you to interview with our hiring manager and/or the interview team. Please note: We do not conduct interviews via text message, Telegram, etc. and we never hire anyone into our organization without having met you face‑to‑face (or via Zoom). You will be invited to come to a live meeting or Zoom, where you will meet our INFUSE team.
• From there on, it’s decision time! If you are still excited to join INFUSE and we like you as much, we will have a conversation about your offer. We do not make offers without giving you the opportunity to speak with us live.

INFUSE is committed to complying with applicable data privacy and security laws and regulations. For more information, please see our Privacy Policy.

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.

We’re looking for a pragmatic tech lead to take us from prototype to scalable product, shipping end‑to‑end features across ingestion, UI, SEO, and auth.

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, 404s, 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.
