Full-Stack Engineer - Workflow Automation Platform

peopleIX is evolving from a people analytics platform into the data and automation engine for HR teams. We enable companies to orchestrate HR processes, connect fragmented systems, and automate high-impact workflows with agentic AI. Our Vision We're building the next-generation HR platform where workflow automation is the core product, powered by our unified people data layer. Think n8n meets HR - enabling teams to create powerful automations using natural language, without IT or data engineering. What Makes Us Different Our platform doesn't just show you what's happening - it acts. We're moving from "insight" to "insight * action," enabling HR teams to build and run workflows themselves: absence triggers, onboarding orchestration, leave management, and intelligent alerts powered by AI. Join Our Journey We're a fast-growing, VC-backed startup seeking exceptional engineers to help us become the AI-first people intelligence and automation platform that legacy HR systems cannot deliver. This is not a role for everyone - we're looking for top 1% talent who thrive on ownership, speed, and impact. Ready to shape the future of HR technology? Let's build something extraordinary together.
