• Professional experience designing, building, and maintaining production software in a modern object-oriented language (e.g., C#, Java, Kotlin, Go, TypeScript, Python, C++).
• Strong command of object-oriented design fundamentals — encapsulation, composition, interface design, SOLID, dependency injection, and common design patterns — with the judgment to know when not to apply them.
• Experience delivering software in a microservice or service-oriented architecture, including defining service boundaries, versioning APIs, and handling distributed failure modes (timeouts, retries, idempotency, partial failure).
• Experience designing and consuming HTTP/REST APIs (or gRPC/GraphQL equivalents), including contract design, backward compatibility, and authentication/authorization patterns.
• Proficiency with relational databases: schema design, indexing, query tuning, transactions, and managed schema migrations.

• Proficiency with Git-based workflows and code review as a routine part of delivery — both giving and receiving substantive feedback.
• Experience with production support and observability: structured logging, metrics, tracing, alerting, and triaging live incidents.
• Track record of senior-level ownership: taking ambiguous problems through design, implementation, and release; decomposing work for others; and raising engineering standards on a team.
• Clear written and verbal communication with both engineers and non-technical stakeholders.

• Familiarity with distributed system patterns such as outbox, saga/compensating transactions, eventual consistency, and idempotent consumers.
• Demonstrated performance and scalability work: profiling, query optimization, caching strategy, or load testing.
• Experience with feature flags and progressive delivery (canary releases, dark launches, trunk-based development).
• Familiarity with static analysis, code quality, and dependency/security scanning tooling (e.g., SonarQube, SAST, SCA).
• Experience modernizing or retiring legacy systems, including incremental migration approaches such as strangler-fig.
• Experience integrating third-party vendor APIs, including handling vendor migrations.
• Multi-tenant SaaS experience, especially entitlements, tiered packaging, or role-based access control.
