• Strong experience with containerized and cloud-native environments, particularly Kubernetes

• Strong software development skills, particularly in Python, with the ability to build automation, integrations, and custom tooling

• Experience integrating heterogeneous infrastructure systems across multiple vendors, APIs, and evolving tool ecosystems

• Familiarity with modern infrastructure automation and emerging agent-based frameworks such as MCP / A2A (or equivalent technologies)

• Exposure to digital twin technologies and simulation platforms such as NVIDIA Omniverse or equivalent

• Strong ability to design, build, and maintain software-driven infrastructure solutions in complex, large-scale environments

Who You Are

• A versatile engineer, comfortable operating in complex and fast-paced environments.

• Driven and fearless, you proactively tackle challenges and overcome obstacles with determination.

• A systems thinker, capable of understanding the broader architecture and identifying dependencies across platforms and technologies.

• A collaborative team player who is enthusiastic, curious, and passionate about problem-solving, thriving both independently and within cross-functional teams.

• An effective communicator with strong interpersonal skills, able to engage with diverse stakeholders and foster collaboration.

• Fluent in English and eager to contribute in a multicultural and international environment.
