Responsibilities

Work effectively with a geographically distributed engineering team and cross-functional partners in a continuously evolving environment

Apply systems thinking to backend and platform design, accounting for feedback loops, constraints, and second-order effects across multiple domains and teams

Ramp up quickly on an evolving platform that includes a legacy PHP monolith within the platform that is being incrementally evolved into modern .NET backend microservices, along with MySQL schemas and data models that support core business workflows

Build high-quality .NET services with clear domain intent, well-defined API contracts, and robust validation

Own backend services end-to-end within your domain, acting as the internal expert on their intent, design, lifecycle, and evolution—including enhancement, refactoring, and deprecation

Partner with senior engineering staff and architects to refine and evolve system architecture, service boundaries, and modernization strategy

Improve legacy behaviors by introducing explicit, action-driven backend transitions and modern workflow patterns that increase clarity, maintainability, and testability

Support platform reliability by writing high-quality, testable code and collaborating with QA to ensure strong unit, integration, and API coverage across critical workflows

Participate in code reviews, technical discussions, and cross-team knowledge sharing to raise the bar on consistency, maintainability, and engineering culture

Troubleshoot and resolve complex issues involving multi-step workflows, state transitions, service interactions, and legacy-to-modern integration points

Contribute to architecture documentation, onboarding materials, and technical design records to support long-term team scalability

Collaborate with platform and DevOps teams to influence CI/CD, deployment, observability, and runtime concerns, while ensuring services meet security, compliance, scalability, and availability standards

Support compliance initiatives with secure coding, documentation, and process rigor
