Job Description
AI Product Engineer
Leadtech Group
• Build and maintain the core multiplatform document system. You’ll own features end-to-end, from idea to production, React frontends, Node.js/Express backends, and PostgreSQL, Databricks integration & data layers. • Ship to learn. Proactively instrument features, measure impact, seek user feedback, and iterate or kill based on what you discover. You treat metrics as a compass, not a report card. • Design and orchestrate agentic AI workflows using modern frameworks (LangGraph, Claude Agent SDK, MCP protocols) and integrate LLMs into product features via prompt chains, tool calling, and function execution. • Collaborate with engineers, designers, and leadership to shape the product roadmap. You’ll have a real voice in what gets built and why. • Build, maintain, and extend automation pipelines and connect them with AI agents, external APIs, webhooks, and cloud services on GCP. • Contribute to database schema design (PostgreSQL, BigQuery), build and maintain RESTful APIs, and help manage our cloud infrastructure on Google Cloud Platform.
Job Requirements
- Python fluency, you can quickly build and utilise a wide range of libraries when the task calls for it.
- 2–5 years of full-stack experience in a high-output team. You know how to balance speed with quality and when to choose one over the other.
- Deep TypeScript & React proficiency on the frontend (Hooks, Context API, Vite, Shadcn UI) and backend (Node.js, Express, REST APIs, PostgreSQL).
- You have taste. You can distinguish between good and bad UX, and you can share examples to demonstrate it.
- You’re AI-native. You reach for agents by default, understand MCP and agentic orchestration patterns, and have built guardrails to trust them more and more. Python proficiency for rapid prototyping is a must.
- You’re self-driven and business-aware. You care about solving real problems and moving the needle on metrics, not just shipping features. Give you context, and you’ll find the leverage.
