• A team-oriented mindset, valuing both winning and losing as a team while maintaining a healthy work-life balance.
• Willingness and ability to travel for internal gatherings and team-building events on an (at most) quarterly basis.

Additional Skills:

• Experience with continuous integration/continuous delivery (CI/CD) pipelines.
• Familiarity with Pub/Sub systems and data processing frameworks like Apache Beam.
