Collaborate with solution architects, product teams, and business stakeholders to define scalable technical solutions
Participate in code reviews, architecture discussions, and technical design sessions
Ensure solutions meet security, performance, reliability, scalability, and maintainability standards
Contribute to reusable frameworks, libraries, and integration patterns
Use AI-assisted development tools such as Codex in day-to-day engineering and review, test, and validate generated code
Diagnose and resolve production issues while considering both technical root causes and business impact
Requirements
5+ years of professional software engineering experience, with strong experience in Python
Proven experience designing and delivering production REST APIs
Strong understanding of API design principles, authentication, authorization, and enterprise integration patterns
Experience building and supporting cloud-native applications and services

Strong written and verbal communication skills
Nice to Have
Experience with MCP (Model Context Protocol) or AI agent integration frameworks
Experience building enterprise automation solutions
Experience with front-end or UI development
Experience with Databricks, cloud platforms, or enterprise AI systems
