Build and maintain both inbound and outbound integrations with third-party platforms (e.g., Salesforce and other external/open APIs)
Design and implement in-house services capable of processing large volumes of data under tight time constraints, optimizing for throughput and latency
Design and maintain RESTful and webhook-based APIs, applying strong patterns for rate limiting, pagination, error handling, versioning, and backward compatibility
Collaborate with product and platform teams to define integration requirements and execution guarantees (SLAs/SLOs)
Build observability (logging, tracing, metrics) into integration systems, and use it to monitor, troubleshoot, and continuously improve production reliability
Lead medium/large feature development independently within agile processes, mentoring engineers and conducting code reviews along the way
Stay current with emerging technologies and evaluate new tools for potential adoption
