Job description

We are looking for a full-stack product developer for Estonian startup Snoika, who can build, ship, and maintain AI-powered features and internal tools. You’ll be the bridge between engineering, product, and non-technical teams - turning ideas into fully working agentic flows, prototypes, and customer-facing functionality. This is not a “task executor” role. This is a “build fast, think big, and own your product” role.

Snoika is the AI marketing engine helping brands become visible inside AI search engines (ChatGPT, Gemini, Perplexity, Claude, Grok). We engineer brand knowledge graphs, publish AI-optimized content at scale, and guarantee real inbound results. Our customers include fast-growing SaaS, manufacturing, fintech, compliance, and more.

Why this role rocks

If you’re the kind of developer who opens ChatGPT before Googling, loves building with n8n, Dify, LangGraph, or LangSmith, and wants to put AI into real production systems - keep reading. You’ll join a team whose members have built solutions for NASA, Google, Microsoft, Bosch and dozens of F2000 enterprises.

Responsibilities

• Build AI workflows using n8n, Dify, LangGraph, LangSmith
• Develop full-stack features (Node.js + React.js)
• Create agentic flows and internal tools for AI-powered marketing
• Integrate APIs, automate SEO & data pipelines
• Ship MVPs quickly and iterate with product/AI teams

Requirements

• Experience with n8n and/or Dify (must-have)
• Hands-on: LangGraph, LangSmith, LLMs, RAG basics
• Strong full-stack: Node.js, React.js
• Prior experience in an agency or fast-paced startup
• Daily ChatGPT user, curious about new AI tech
• Basic understanding of SEO/structured data

Nice to Have

• Vector DBs (Pinecone, Qdrant, pgvector)
• Scraping/crawling experience
• Headless CMS experience

The toolkit you’ll use

• Front-end: React 18+ / Next.js, Vite, Tailwind, Materia UI, React-Query, D3 or Recharts.
• Back-end: Node.js 20+, TypeScript, Express or NestJS, TypeOrm or Postgres, Redis, Langchain, RabbitMQ Pub/Sub.
• Cloud: AWS, Kubernetes.
• CMS: Strapi
• Quality: Jest, Cypress, Datadog.
• Collaboration: ClickUp+Scrum, Figma.

What we offer

• Build real AI products used by global brands
• Collaborate with PhDs and operators who’ve scaled technologies at global brands
• Competitive salary and opportunity for career growth.
• Async-first culture; we measure outcomes, not hours.
• See exactly how your work moves the needle on client conversions.

If you're excited to push the boundaries of AI Search Engine Visibility and Optimization and want to help shape the future of marketing technology, we want to hear from you!
