Engineering Lead, Full Stack (Hands-on)

Hooh is a B2C AI-powered document understanding platform offering PDF processing, extraction, and conversational Q&A capabilities. We are hiring a hands-on Engineering Lead (Full Stack) to own the end-to-end architecture, reliability, and delivery of our engineering system while leading a small, high-output team.

This role offers a clear growth path into Head of Engineering or CTO as the team scales.

• End-to-End System Ownership: Own the entire pipeline from document ingest and processing (OCR/extraction) through AI workflows, APIs, and iOS/web experiences. Design and evolve API surfaces for document ingestion and AI-driven summarization.
• Architecture & Execution: Define service boundaries, API contracts, data models, and rollout patterns. Engage in design reviews spanning service decomposition and CAP trade-offs.
• Hands-on Engineering: Ship core features across backend and web (React/Next.js/Node.js). Unblock teammates and set quality standards through exemplary PRs and technical decisions. Optimize frontend hydration, bundle-splitting, and rendering concurrency.
• Reliability & Trust: Ensure reliability through idempotency, non-blocking execution, and horizontal scalability. Implement security best practices around authentication, encryption, and secure data handling.
• Team Leadership: Improve delivery cadence through clear ownership, strong reviews, and pragmatic processes while keeping the team moving fast with confidence.

• Experience: 5-7 years shipping production systems, with strong preference for startup or high-ownership environments.
• Full-Stack Fluency: Deep expertise in TypeScript/JavaScript across backend (Node.js/Express) and frontend (React/Next.js).
• Database Depth: Advanced literacy in Postgres/MySQL, including schema evolution, query planning under load, read/write splitting, and connection pool tuning.
• Cloud & Infrastructure: Proficiency with AWS/GCP/Azure, containers (Docker/Kubernetes), CI/CD, and IaC (Terraform/CDK).
• Async Architectures: Experience with message queues (Kafka/SQS) and background job frameworks.
• Product Judgment: Ability to balance speed, quality, and architecture without over-engineering.
• Communication: Clear communicator who can align a small team and keep execution crisp.
• Nice to Have: Mobile-first products (iOS integration constraints), PDF/document tooling experience, and operationalizing AI/LLM features in production.

• Schedule: Flexible schedule with fully remote work from anywhere with reliable overlap to CET.
• Vacation & Time Off: 18 paid vacation days, 8 no-paperwork sick days, and 11 public holidays per year.
• Work Environment: Minimal bureaucracy, high trust, fast decisions.
• Benefits: Challenging technical problems, clear growth path into Head of Engineering/CTO, direct influence on strategy, and ability to ship experiments fast.
