Java Full Stack Developer
Explicitly calls for vibe coding: collaborative AI-assisted workflows, AI copilots, and converting prompts into production code.
About the Role
Senior Java Tech Lead focused on hands-on backend engineering and squad leadership, delivering secure, scalable services using Java/Spring Boot, cloud, containers, and CI/CD. The role emphasizes integrating GenAI tools and LLM platforms into production systems while mentoring engineers and driving reliability and API design.
Job Description
Role
Hands-on Tech Lead (individual contributor lead) responsible for shipping secure, scalable backend services with a high coding cadence (approximately 60β70% coding, 30β40% technical leadership). Drive design, reliability, CI/CD, and AI-enabled productivity while mentoring engineers and leading squads/streams.
Key Responsibilities
- Design, build, and scale RESTful APIs with attention to versioning, schema evolution, and backward compatibility.
- Implement and maintain data models and performance patterns for MySQL/PostgreSQL and MongoDB/Cassandra (indexing, optimization, caching).
- Implement RBAC and modern auth flows (OAuth2/OIDC, JWT) and apply security best practices.
- Lead design, code reviews, and Git workflows (trunk-based or GitFlow); enforce branching strategies and quality gates.
- Build and operate production-grade containerized deployments using Docker and Kubernetes (deployments, services, ingress, HPA, rollout/rollback).
- Drive CI/CD, reliability, testing (unit, integration, contract such as Pact, performance), and API documentation (Swagger/OpenAPI, Postman).
- Integrate cloud services (compute, networking, storage, IAM, managed DBs) on at least one major cloud provider (AWS/GCP/Azure).
- Mentor and ramp engineers, set team guardrails, and provide technical leadership while remaining hands-on.
GenAI & AI Tools
- Use AI coding copilots and code-generation tooling in daily workflows; set team policies and guardrails for AI-assisted development.
- Integrate at least one LLM platform (e.g., Azure OpenAI, AWS Bedrock, Vertex AI, OpenAI, Anthropic) into backend services.
- Implement RAG solutions using vector stores (OpenSearch, pgvector, Pinecone, Redis) and embeddings.
- Apply prompt engineering, evaluation, model lifecycle practices (versioning, offline/online evaluation, A/B testing), telemetry, and safety/abuse handling.
- Support collaborative, AI-assisted development workflows (βvibe codingβ) and convert exploratory prompts into production-grade code and tests.
Requirements
- 5β7 years total experience in backend/platform engineering with recent, strong hands-on Java and Spring Boot experience.
- 3β5 years leading squads/streams while remaining deeply technical.
- Proven experience building production RESTful APIs and data systems using MySQL/PostgreSQL and MongoDB/Cassandra.
- Practical experience with OAuth2/OIDC, JWT, RBAC, Git workflows, and API tooling (Swagger/OpenAPI, Postman).
- Production experience with Docker and Kubernetes and cloud platforms (AWS, GCP, or Azure).
- Testing experience across unit, integration, contract (e.g., Pact), and performance testing.
- Strong communication skills and ability to deliver independently.
Nice to Have
- Daily use of AI coding tools in IDE/CLI and experience setting team guardrails.
- Hands-on integration experience with LLM platforms and practical prompt engineering experience.
- Experience with RAG architectures and vector stores (OpenSearch, pgvector, Pinecone, Redis).
- Familiarity with model lifecycle, telemetry, A/B testing, and safety/abuse mitigation.
