• You have to be physically in any of the European countries GMT 0 to GMT +3.
• Ability to work independently and collaboratively within a team
• A proactive, problem-solving mindset with a “yes, we can” attitude.

Responsibilities:

• Enhance the developer experience by identifying and addressing friction points through concrete data from observability, through developer feedback and developer experience surveys.
• Develop and maintain observability solutions (metrics, tracing, logging) that provide objective, measurable insights into the behavior and performance of the internal tools and processes owned by the Tooling Team, enabling data-driven identification of pain points, and guiding future efforts to enhance the overall developer experience.
• Partner with other engineering teams to gather requirements for the owned tooling and to drive best practices that improve productivity.
• Continuously evolve internal tooling to streamline workflows, standardize processes, and maintain strong alignment with company security and operational standards.

What’s in it for you?

• Competitive salary (€6,500 - €9,000 gross, depending on the level of experience)
• Enjoy a flexible, remote-first global environment.
