Job description
Staff AI Engineer (d/f/m)
Company Overview
Personio's intelligent HR platform helps small and medium-sized organizations unlock the power of people by making complicated, time-consuming tasks simple and efficient. Our team of 1,500 Personios is building user-friendly products that delight our 15,000+ customers and their 1.5 million employees.
Job Summary
Personio is on the path to becoming an AI-first company, redesigning how every department operates, and the Internal AI team is leading that transformation from the inside. The Staff AI Engineer is the technical anchor of that mission. You take on the most complex, ambiguous problems on the roadmap — the ones without a clear playbook — and set the technical standard the rest of the team works to.
Key Responsibilities
- Tackle the hardest problems: Own the most complex, ambiguous internal products and tools end-to-end.
- Make the architecture calls where the stakes are highest: navigate ambiguity, manage risk, and set a direction others can build on.
- Establish the bar for what production-grade internal tooling, automations, and AI looks like at Personio.
- Productionise and maintain: Define what "done" means for internal products at Personio and hold the team to that bar.
- Shape the AI platform: Work closely with the AI Platform team to shape the direction of shared infrastructure.
- Technical leadership: Set the technical direction for the Internal AI engineering team, develop other engineers through mentorship, and represent the team's technical perspective in cross-functional discussions.
Requirements / Qualifications
- 7+ years building and shipping production software.
- Technical leadership: you set engineering standards and shape architecture across a team.
- Expert Python skills — our primary backend language — across distributed systems, APIs, and data integration.
- Deep hands-on experience building production AI products: agentic workflows and RAG pipelines with LLM APIs, agent frameworks (e.g. LangGraph), and MCP.
- Judgement about where AI adds value and where it's overkill.
- A track record of production-grade work at scale: testing, observability, documentation, and secure handling of auth and data (SSO, OAuth, RBAC, GDPR).
- Experience deploying and operating services in the cloud (AWS, Docker, CI/CD).
Preferred Qualifications
- React/TypeScript for internal interfaces.
- Kotlin (Python is our main backend language; Kotlin is a plus).
Location
Munich, Berlin, or Dublin (Hybrid)
Employment Type
Full Time
Salary & Benefits
- Competitive reward package – reevaluated each year – that includes salary, benefits, and pre-IPO equity.
- 28 days of paid vacation, plus an additional day after 2 and 4 years.
- 1 (fully paid) Impact Day.
- Generous family leave, child support, mental health support, and sabbatical opportunities.
- Office-led, remote friendly approach.
- Healthy snacks, drinks, and a weekly catered lunch.
