• Proven experience developing software in agile teams of 5+ engineers, including version control and CI/CD workflows.
• Solid grasp of JVM languages (Java, Scala, Kotlin); bonus if you’re familiar with other programming paradigms.
• Exposure to public or hybrid cloud environments (AWS preferred).
• Comfortable working with multiple data stores, API access layers, and system integrations.
• Proficient in debugging, testing, and monitoring tools and practices.
• Experience building and supporting software in production environments.
• Strong problem-solving skills with the ability to balance business objectives and technical feasibility.
• Ability to understand how your code fits into broader architectural and product goals.

🎯 What You’ll Gain
