As an AI Automation Engineer in Leadtech’s Applied AI Lab, you will connect powerful AI agents and LLMs to real-world workflows using low-code orchestration tools like n8n, Retool, and KNIME, along with scripting and backend APIs.
You will design automations that integrate foundational AI models, APIs, databases, and user-facing systems, enabling fast, scalable, and maintainable deployment of intelligent workflows.
Your responsibilities include building, maintaining, and extending end-to-end automation pipelines using n8n or Retool Workflow.
You will automate tasks across systems such as vector DBs (Pinecone, Weaviate), OpenAI/Gemini APIs, Notion, Slack, email, storage, and webhooks, and design and deploy multi-step processes involving LLMs via prompt chains, tool calling, and function execution.
You will set up listeners and webhooks to automate tasks based on events, route user inputs, analyze outputs, and trigger relevant services through low-latency pipelines.
You will rapidly prototype and deliver AI-powered automations to support internal users, marketing, content ops, product intelligence, and more.
Collaboration is key; you will work closely with product managers and AI specialists to translate complex requirements into robust, scalable features.
You will build and maintain backend infrastructure to support agent and model endpoints via FastAPI or Express.
You will also collaborate with the team on application deployment and help maintain our cloud infrastructure on Google Cloud Platform.
Requirements:
You should have 6 months to 3 years of professional experience in a relevant role.
Mastery of n8n is required, including the ability to build custom workflows and custom nodes.
You must be comfortable using n8n with webhook triggers, data parsing, retries, error handlers, and LLM toolchains.
Understanding how to secure, scale, and monitor n8n in production is essential.
Previous hands-on experience with LangChain is necessary.
Awareness of LangFlow's features and its pros and cons is preferred.
Proficiency in programming and scripting languages such as Python, TypeScript, Bash, and workflow scripting (e.g., YAML-based pipelines) is required.
Familiarity with FastAPI, Node.js, and database integration (PostgreSQL, Redis, BigQuery) is important.
A collaborative problem-solving mindset is essential, along with a genuine passion for artificial intelligence and a strong desire to build products that leverage its capabilities.
Creativity and proactivity in proposing new features and improving user experience are highly valued.
