Opportunity – Staff AI Platform Engineer

We are looking for a Staff AI Platform Engineer to help us build the next generation of our AI-powered Internal Developer Platform.

About the role

In this deeply hands-on role, you will lead through technical excellence by building the platform's most complex, business-critical capabilities. You will design, build, and evolve reusable platform tools—including AI agents, AI-powered CLIs, Kubernetes Operators, and Golden Paths—to empower hundreds of engineers and data scientists to deploy software faster, safer, and with greater autonomy.

What we’re looking for:

- Proven hands-on track record delivering production software in Python (primary language) and Go for systems-level components (Kubernetes Operators/controllers).
- Solid experience designing and building large-scale developer platforms used by large engineering organizations, with a strong focus on Developer Experience (DevEx).
- Deep experience with cloud architecture, particularly AWS, as well as containerization and orchestration (Docker, Kubernetes, ArgoCD/Flux).
- Active leverage of AI-native engineering workflows (Claude Code, Cursor, Copilot, etc.) to accelerate delivery, with bonus points for building AI agents, RAG, or MCP infrastructure.
- Technical leadership by example: a mentor who shapes architecture through prototypes, code reviews,



and reference implementations rather than rigid processes (~10+ years of software experience is a helpful guide, but impact matters most!).

Sector: IT & Digital Transformation / Software Engineering

Why join this project?

- People first – inclusive, diverse, and international culture.
- Work with cutting-edge technology on global-scale products.
- Clear opportunities for career progression and continuous development.
- Collaborative teams with a strong sense of belonging.
- Access to learning resources and development programs.
- Private health insurance & benefits (according to region).
- Flexible working environment and hybrid model.
- Wellness and mental-health initiatives.
- Team-building activities and integral community events.
