Lead Java Developer

Responsibilities

• Lead end-to-end design, development, and delivery of full stack applications built on React/Next.js (frontend), Spring Boot/Java or Node.js (backend), deployed on AWS
• Architect and implement cloud-native, event-driven solutions using Lambda, ECS, API Gateway, DynamoDB, S3, EventBridge, and IAM
• Own complete project delivery across one or more client engagements simultaneously — from requirements through production
• Develop and maintain technical documentation including architecture decision records (ADRs), runbooks, and integration specs in Confluence
• Translate ambiguous business requirements into system designs — challenge the spec, identify gaps, propose better solutions
• Lead and mentor a team of engineers; participate in daily agile and scrum processes
• Drive architecture decisions in collaboration with principal architects; establish and enforce cross-project technical standards
• Manage vendor and third-party integrations end-to-end
• Set up and maintain sandbox environments and testing automation pipelines
• Interact directly with senior client stakeholders — present architecture, drive alignment, own the technical relationship

Required Skills

• 8+ years of overall experience; 5+ years building production systems on AWS
• Hands-on full stack development — React/Next.js on the frontend, Spring Boot (Java) or Node.js on the backend
• Deep AWS expertise: Lambda, ECS, DynamoDB, API Gateway, S3, EventBridge, IAM, serverless and event-driven architecture
• DynamoDB data modeling — partition key design, GSI strategy, single-table vs multi-table tradeoffs, capacity planning
• Experience writing and maintaining technical documentation — ADRs, architecture docs, runbooks — in Confluence or equivalent
• Proven ability to lead project delivery, manage engineers, and operate autonomously across complex engagements
• Strong written and verbal communication skills; comfortable presenting to VP and C-suite audiences

Good to Have

• Amazon Connect, Lex, Polly or equivalent contact center / telephony experience
• Terraform or CloudFormation for infrastructure as code
• PostgreSQL + JSONB or NoSQL modeling for application consolidation projects
• QuickSight or similar BI tooling for reporting pipelines
• AI-first mindset — familiarity with MCP, Claude Code, Kiro, or agentic tooling
