Responsabilidades

Own backend architecture across the platform and lead the incremental decomposition of a large monolith into well-defined, maintainable services.

Establish backend engineering standards, best practices, and tooling, including shared libraries, service templates, and cross-cutting platform capabilities.

Lead API and contract design, ensuring effective versioning, backward compatibility, and reliable communication between internal services, frontend applications, and external integrations.

Own event-driven architecture using Azure Service Bus, including message delivery guarantees, retries, idempotency, and failure recovery.

Define scalable patterns for customer and partner integrations, ensuring failures are observable, traceable, and recoverable.

Collaborate with the Data Architect on data ownership, transactional boundaries, access patterns, and query performance.

Improve platform reliability, security, observability, and cloud cost efficiency.

Champion AI-assisted engineering practices and help expand the team's capabilities through practical adoption of AI tools and workflows.

Mentor engineers, review critical pull requests, facilitate technical office hours, and document architectural decisions through Architecture Decision Records (ADRs).

Deep, hands-on expertise in C# and.NET, with a proven track record of designing and delivering secure, scalable, and resilient commercial backend systems.

Practical experience with Azure services, particularly Azure Functions, Azure Service Bus, and Azure Data Factory.

Experience working with PostgreSQL, Cosmos DB, Snowflake, CI/CD pipelines, and DevOps practices.

Demonstrated success incrementally decomposing large monolithic systems, prioritizing safe, reversible changes over disruptive rewrites.

Strong understanding of event-driven and asynchronous architectures, including message ordering, idempotency, poison messages, retries, and dead-letter queues.

Extensive experience with API design, service contracts, versioning, and backward compatibility.

Strong data-access fundamentals, including query optimization, zero-downtime migrations, and handling inconsistent or complex customer data.

Proven production ownership, including observability, alerting, incident response, and root-cause analysis.

Required: Daily, hands-on use of AI development tools such as Claude, Claude Code, or comparable agentic engineering tools, along with practical experience building AI-powered solutions involving agents, reusable skills, MCP servers, or evaluations.

Excellent written and spoken English, with the ability to communicate complex technical concepts to both technical and non-technical audiences.
