- Participate in improving CI/CD pipelines, observability, and dev tooling
Requirements
- 2–5 years of professional software engineering experience
- Strong proficiency in Python and backend development fundamentals
- Experience working with RESTful APIs, databases (SQL/NoSQL), and cloud platforms (GCP preferred)

- Strong communication skills and a collaborative, problem-solving mindset
- These are the applicable requisites, although equivalent competencies in any of the above will also be considered
