Hooh

Вітаю тебе, фахівець \0/

Мене звати Кирил, я допомагаю зібрати дрім тім для своїх друзів з Hooh – це стартап від фаундерів Depositphotos. Команда сіньорна та досвідчена, тому опортʼюніті, ІМХО, дуже кльове.

отже

Hooh – це b2c AI-продукт, який робить складні документи простими для розуміння та дій. 

Він дозволяє завантажувати файли (PDF, фото, скани), автоматично розпізнавати їхній вміст, витягувати ключову інформацію та отримувати короткі, зрозумілі підсумки.
 

Ми успішно випустили v1, підтвердивши нашу основну AI-пайплайн-архітектуру. Зараз ми розширюємо продукт до “scanner-grade” PDF-досвіду, що поєднує глибоке AI-розуміння з надійним редагуванням документів.

_________________

CEO about the role: “We are looking for an Applied AI Engineer who will help us make messy documents reliably understandable, build accurate structure and entity extraction, strong retrieval, and cost‑efficient model orchestration."

Key Responsibilities

• Document analysis & taxonomy: Systematically analyze layouts/sections/entities/relations; define categories, types, and metadata schemas that generalize across domains.
• Prompting & schemas: Author, version, and maintain prompts/chains for classification, extraction, summarization, and Q&A; enforce JSON/JSON‑Schema outputs.
• Retrieval (RAG): Build hybrid retrieval (embeddings + keyword + graph traversal); manage embedding generation, indexing, dedupe, and drift.
• Cascades & MoE: Architect model cascades (fast filters → experts → fallback LLMs) and MoE routing to balance quality/cost/latency.
• Agentic orchestration: Use CrewAI (or similar) to coordinate multi‑step pipelines; add caching/batching/streaming and robust retries.
• Result fusion: Combine outputs via reranking, voting, and confidence/consistency checks; add guardrails and safety rules.
• Evaluation & monitoring: Run LangSmith/Evals (or similar), define golden sets, automate regressions, track quality/cost/latency; canary and observe.
• Operate models locally/hosted: Work with vLLM/TGI/Ollama/llama.cpp as well as API models; apply quantization/LoRA when useful.
• Data stores: Use vector DBs plus graph and relational DBs to power retrieval and joins (e.g., Qdrant/Weaviate/Milvus/pgvector + Neo4j + PostgreSQL).

Required Skills & Experience

• Strong programming skills in Python; ability to write clear, tested, maintainable code.
• Experience building at least one LLM‑powered feature end‑to‑end (prototype → production), or equivalent open‑source/portfolio work.
• Hands‑on with RAG, vector embeddings, and evaluation (offline + online A/B, error analysis).
• Familiarity with model cascading/MoE concepts (or ability to learn quickly).
• Practical database skills: comfortable with SQL and with either graph or vector systems.
• Product mindset: bias to measure impact and iterate.

We hire for capability and learning speed. If you’re strong on fundamentals and can show work, we’d love to talk, even if you don’t check every box.
 

Nice to have:

• OCR/Document AI, ontology design, labeling workflows.

_________________

We’re hiring a Product Manager who can turn a strong product vision into consistent shipping.
 

This is a high-velocity execution role: you’ll translate high-level goals into crisp specs, coordinate delivery across engineering, and ensure we ship the right things on time.
 

You’ll work closely with the founding team, engineers and designers to keep the roadmap focused, the backlog sharp, and releases predictable.
 

You will be building an iOS + web platform for AI document understanding (OCR, summary, chat) and manipulation (editing & productivity).
 

If you enjoy building lightweight process, unblocking teams, and getting features into users’ hands quickly, you will fit here.

Key Responsibilities

• Turn goals into specs: write clear PRDs/specs with edge cases, UX states, and acceptance criteria so engineering can build without guessing.
• Own delivery cadence: sprint rhythm, backlog grooming, release planning, and cross-functional coordination (engineering + design).
• Make shipping predictable: lightweight workflows (Jira), release checklists, and crisp definition-of-done.
• Prioritize ruthlessly: keep focus on the highest-impact work; protect the team from churn and scope creep.
• Close the loop: define success metrics, gather user feedback, and iterate based on real usage (not opinions).

What We’re Looking For

• 4+ years of Product Management experience, ideally in startups where "process" was something you had to build, not just follow.
• Mobile-First Experience. You’ve built and shipped mobile apps. Growth, retention, performance, and platform constraints are part of your daily work.
• High Execution. You care more about shipping value over "being right" or perfect narratives.
• Process Architect. You’ve implemented delivery workflows that teams actually follow.
• Data-Savvy. You rely on data to validate hypotheses. You are comfortable digging into dashboards (we use PostHog) to answer your own questions without needing a data analyst.
• Technical Fluency. Comfortable discussing APIs, latency, trade-offs, and constraints with engineers.
• Direct communicator. You surface risks early and manage expectations transparently.

Nice to Have Experience With

• Consumer Mobile Apps (iOS subscription mechanics).
• Productivity Tools (PDF, Notes, Editors).
• AI-enabled products.
• "Founder-led" startup.
