• Work closely with Product, Data, Security, and Platform partners to translate requirements into robust technical solutions
• Develop modern front-end applications using React or Angular with TypeScript, with a strong focus on usability and performance
• Build and maintain backend services and APIs using RESTful patterns and modern frameworks (e.g., FastAPI, Node.js)
• Implement asynchronous processing, event-driven workflows, and API versioning strategies as part of production system
• Contribute to cloud-native and microservices-based architectures in real-world environments
• Hands-on experience with AI-assisted development tools such as Cursor, Claude Code, and Windsurf
• Implement and integrate AI/ML capabilities into applications, including model inference APIs and data-driven workflows
• Make informed tradeoffs between real-time and batch processing, latency, throughput, and scalability
• Collaborate with Data Science and ML Engineering teams to operationalize AI features in production systems
• Build secure applications with strong attention to authentication, authorization, and data protection
• Implement identity and access patterns such as OAuth2, RBAC, and session management
• Ensure systems include appropriate logging, observability, and auditability aligned with enterprise and regulatory expectations
• Contribute directly to CI/CD pipelines and DevOps workflows that support rapid, reliable delivery
• Build and deploy containerized applications using tools such as Docker and modern deployment pipelines
• Monitor and improve system performance, reliability, and resilience to meet defined service-level objectives (SLOs)
• Act as a senior technical contributor who leads by example through high-quality design and code
• Provide mentorship and guidance to other engineers through collaboration, reviews, and technical discussion
• Influence technical direction and best practices without direct people management responsibility
• Serve as a trusted technical partner to stakeholders across engineering, product, and platform teams
