A Day in the Life of Technical Lead Java, Spring AI-Augmented Engineering

As the Technical Lead, you are the hands-on guardian of the codebase . You will partner with our Solution Architect to translate high-level designs into high-performance Java/Spring applications. Your primary mission is to lead a squad of developers by example mandating the use of AI coding assistants to achieve unprecedented velocity and code quality in our API and integration layers.

In this role, You will..

1. AI Coding Velocity (Team Lead Ownership)

• AI-First Development: Standardize the use of GitHub Copilot/Cursor across the squad. You are responsible for the 20-30% productivity gain expected from AI augmentation.
• Prompt Governance: Create a library of “Prompts” for the team to generate Spring boilerplate, complex SQL mappings, and integration test suites.
• Quality Control: Ensure AI-generated code meets L’‘Orals security and performance benchmarks (preventing “AI-hallucinated” vulnerabilities).

2. Implementation of Integration Patterns

• Pattern Execution: While the SA defines the pattern (e.g., Saga or Event-Driven), you implement it. You will write the core Spring Cloud Stream logic that ensures data consistency.
• API Craftsmanship: Build and refine REST/gRPC APIs, focusing on implementation details like custom filters, interceptors, and error-handling strategies.
• Cloud-Native Development: Architect and implement Spring Boot microservices specifically optimized for GCP (GKE, Cloud Run, Pub/Sub) or Azure (AKS, App Service, Service Bus).

3. Spring Ecosystem Expert-in-Residence

• Deep-dive into Spring Boot 3.x features.
• Lead the implementation of Spring Security (OAuth2/OIDC) and Spring Data performance tuning (Hibernate caching, query optimization).

4. Squad Mentorship PR Leadership

• Own the Pull Request (PR) process. You are the final gatekeeper for code merging.
• Bridge the gap between the Architect’’s vision and the Developer’’s daily tasks.

• Java Depth: Expert Java 17/21 (Records, Virtual Threads/Project Loom).
• Cloud Expertise: 3+ years of hands-on experience in Google Cloud (GCP) or Microsoft Azure. Certification (e.g., Google Professional Cloud Developer or Azure Developer Associate) is a significant plus.

Soft Skills Qualifications

• Experience: 9+ years in Java Engineering, with 2+ years leading a squad.
