• Create and maintain APIs that are utilized by internal services, external integrations, and our own frontend applications.

• Engage in architectural discussions and enhance service-oriented, event-driven systems.

• Enhance system reliability, performance, and observability throughout the entire technology stack.

• Refactor and update legacy systems as the platform progresses.

• Diagnose production issues and implement enduring solutions.

• Collaborate with product and design teams to translate requirements into functional, well-tested features.

• Participate in code reviews and promote high engineering standards.

• Utilize AI-driven development tools, such as Claude, to expedite software design, implementation, testing, debugging, documentation, and code review.

• Exercise strong engineering judgment when evaluating AI-generated solutions, ensuring their correctness, maintainability, security, performance, and compliance with set architectural standards.

• Employ AI to navigate unfamiliar codebases, investigate defects, assess implementation options, and identify potential edge cases or system impacts.

• Use AI tools responsibly, ensuring that proprietary data, customer information, credentials, and other sensitive materials are managed in line with company security protocols.

• Share effective AI workflows, reusable prompts, and best practices that enhance engineering productivity and quality across the team, while also evaluating emerging AI development tools that may be beneficial to adopt.
