Full-Stack Engineer - Workflow Automation Platform (m/f/d)

**Building the AI-First HR 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.

## Tasks

**Build the Workflow Automation Engine**

• Architect and develop our core workflow automation platform
• Create HR-specific workflow templates: time-based triggers, analytical thresholds, event-driven processes (onboarding, offboarding, leave management), and webhook integrations
• Build our natural language workflow builder, enabling HR teams to create automations through plain text prompts

**Drive Full-Stack Platform Development**

• Own complete features end-to-end, from database schema to API to polished UI – at peopleIX, full-stack means genuine ownership of the entire feature lifecycle
• Develop our scalable integration framework connecting Slack, Teams, email, and core HR systems (Personio, DATEV, SAP)
• Shape our People Data Platform: robust data modeling, custom fields, and data quality monitoring

**Integrate AI & Agentic Capabilities**

• Extend our proprietary AI agent Tira with automation capabilities, moving from insights to autonomous actions
• Build intelligent triggers and AI-powered recommendations that drive real workflow execution
• Pioneer agentic experiences that redefine how HR teams interact with their data

**Collaborate at High Velocity**

• Partner directly with our CTO and cross-functional teams to ship features rapidly
• Work closely with customers to iterate based on real-world feedback
• Take full accountability from concept through deployment and production monitoring

**Shape Our Engineering Culture**

• Play a foundational role in defining our technical standards, team dynamics, and development practices
• Influence architecture decisions and product direction as we scale further
• Help build a world-class engineering organization from the ground up
