• Own larger, complex initiatives end-to-end—from discovery and requirements through delivery and production support—driving alignment across engineering and business stakeholders.
• Collaborate with software and production engineers to design scalable services, plan feature roll-out, and ensure high reliability and performance of our products.
• Design and develop systems across all major departments including but not limited to; data, enterprise applications, and IT.
• Lead technical design and architecture decisions across multiple systems/services, and help establish standards, patterns, and best practices.
• Modify and develop custom software patterns as needed to solve highly complex software problems, and clearly document tradeoffs and long-term maintenance implications.
• Be accountable for the overall performance of products and/or services within a defined area of focus, including diagnosing production issues and driving improvements.
• Conduct code reviews, develop high-quality documentation, and build robust test suites for your products (unit/integration testing), ensuring maintainable and well-covered code.
• Provide technical leadership through mentoring, coaching, and strong design/code review feedback, helping raise overall engineering quality.
• Develop roadmaps and prioritize technical debt to effectively plan features and work, balancing delivery with long-term platform health.
• Drive operational maturity (observability, incident response, on-call practices, reliability goals) and lead post-incident analysis with preventative action plans.
• Handle multiple competing priorities in an agile, fast-paced environment while maintaining strong engineering discipline and delivery quality.
• Perform additional duties as assigned.

• Strong experience integrating 3rd-party APIs, implementing authentication & authorization and developing asynchronous data flows.
• Strong experience publishing and consuming Kafka events, including designing event contracts, building reliable event-driven workflows, and handling ordering, retries, idempotency, and failure recovery.
