Automation Engineer

You’re the kind of person who sees a manual process and immediately starts thinking about how to eliminate it. At Kainjoo, you’ll build the automation layer that connects our clients’ tools, APIs, and data — and increasingly, you’ll weave AI into those workflows to do things that weren’t possible before.

What you’ll be doing

You’ll design and build production automation workflows across a wide range of client use cases — from document processing and CRM syncing to AI-powered scoring and classification. You’ll work with a lot of different APIs, a lot of edge cases, and a lot of creative problem-solving.

• Design and build automation workflows using tools like n8n, Make, or similar platforms
• Integrate third-party APIs across CRM, accounting, communication, marketing, and productivity tools
• Build AI-powered workflows using LLM APIs for classification, summarisation, extraction, and scoring
• Implement both event-driven and scheduled (cron-based) automation patterns
• Connect automation outputs to databases, spreadsheets, and client systems
• Set up error handling, alerting, and observability for production workflows
• Test, debug, and monitor live automations in production
• Document workflows clearly for handover and client training
• Collaborate with developers to define API endpoints that workflows can consume

Who we’re looking for

Personality

• You enjoy figuring out how to connect things that weren’t designed to connect
• You’re persistent — you dig into API docs, you test edge cases, you don’t give up easily
• You document your work well so others can maintain it
• You’re pragmatic: you use the right tool for the job, not the most impressive one
• You stay curious about what’s new in the AI and automation space

Experience* 2+ years of experience building production automations with tools like n8n, Make, or Zapier

• Strong understanding of REST APIs, webhooks, and OAuth flows
• Comfortable writing JavaScript or Python for custom logic and data transformation
• Experience with both event-driven and scheduled automation patterns
• Experience integrating LLM APIs (OpenAI, Anthropic, or similar) into production workflows
• Ability to set up monitoring and error alerting for production workflows

Nice to Have* n8n experience specifically (self-hosted a plus)

• Familiarity with Google Workspace APIs
• Background in data engineering or ETL processes
• Experience with vector databases or RAG architectures
• Knowledge of Notion or similar workspace APIs

Education

• Bachelor’s degree in Computer Science, IT, or equivalent practical experience
• Fluent in English; French is a plus
