• Think at Scale: You connect your day-to-day work to the broader business mission, designing solutions, processes, and architectures that are built to last and support high-growth global platforms
• A Problem-Solver: You seek out challenges and derive energy from finding solutions, knowing that solving hard technical problems yields the greatest impact
• A High-Trust Collaborator: You thrive in a culture of candid feedback, exchanging ideas with clarity and respect to build deep trust across cross-functional engineering teams
• Data-Driven: You leverage metrics and data to evaluate system performance, validate technical decisions, and replace assumptions with evidence

What We’re Looking For (Minimum Qualifications)

• 8+ years of hands-on software application development experience building production-grade software
• Core Backend Expertise: Strong hands-on experience with Java, Spring Boot, Spring Framework, or Quarkus Framework
• Distributed Systems: Proven expertise in building distributed, cloud-native applications focused on high availability, scalability, and reliability
• Cloud & Containerization: Deep experience with containerized deployments (Docker / Kubernetes) hosted on cloud platforms such as AWS or GCP
• Agile Autonomy: Proven ability to adapt quickly and work independently within a fast-paced Agile environment with minimal supervision
• AI Curiosity: Demonstrated curiosity and active exploration of AI tools, with a history of integrating new technologies to streamline workflows and augment problem-solving

What Will Make You Stand Out (Preferred Qualifications)

• Polyglot Mindset: Comfort and flexibility in switching between languages (such as Java, Go, Python, or C++) based on project requirements
• Advanced DevOps & CI/CD: Hands-on experience designing and writing complex GitLab CI/CD pipelines and automated release workflows
