• Collaborate on this modernization journey: Design and implement patterns for legacy displacement to move domains out of our monolith with zero downtime. • Bridge Tech Stacks: Build new services and help transition others from .NET to Spring while navigating and contributing to other codebases. • Product Collaboration: Partner with product managers to question and form requirements, understand the "Why", and help shape a roadmap that balances technical debt with new value. • Global Collaboration: Communicate effectively across timezones. Your written documentation and async communication will be the glue for our distributed team. • Master Observability: Use Grafana and modern tracing to monitor system health, ensuring our backend-heavy domain remains performant and reliable. • Drive AI Efficiency: Leverage Agentic programming tools (like Claude Code) to accelerate refactoring and development workflows. Use it to deal with obvious problems and focus on the complex ones.

You don’t just take tickets; you seek to understand the business impact of your architectural choices. • Observability Advocate: You don't wait for a crash to know there's a problem; you build systems that tell you how they're performing.
