What you'll bring:

• Bachelor's/Master’s degree in Computer Science, engineering, or related field, with minimum 10+ years of experience in software design, development and automated deployments.
• Have prior experience in delivering highly scalable large scale data processing Java applications.
• Strong in high- and low-level system design. Should be experienced in designing data intensive applications in open stack.
• A good understanding of CS Fundamentals, Microservices, Data Structures, Algorithms & Problem Solving
• Should be experienced in CICD development environments/tools including, but not limited to, Git, Maven, and Jenkins.
• Strong in writing modular and testable code and test cases (unit, functional and integration) using frameworks like JUnit, Mockito, and Mock MVC
• Hands on experience building Java-based backend systems and experience working in cloud-based solutions is a must. Proficient in Java, Spring Boot, Kafka, and Spark.
•  Experienced in microservices architecture. Possesses good understanding of distributed concepts, common design principles, design patterns and cloud native development concepts. 
• Hands-on experience in Spring boot, concurrency, garbage collection, RESTful services, data caching services and ORM tools.

Good to Have

• Python — ability to read/write Python for scripting, data pipelines, or lightweight AI/ML tooling that complements the core Java stack.

• Familiarity with architecting GenAI-augmented features within existing Java/Spring Boot systems — knowing when an LLM-based solution is (and isn't) the right architectural choice compared to traditional rule-based or ML approaches.

• Understanding of Retrieval-Augmented Generation (RAG) patterns at a system-design level — evaluating vector store options (Pinecone, Azure AI Search, pgvector), chunking/embedding strategies, and how retrieval pipelines fit into existing service architectures.

• Exposure to integrating and governing LLM APIs (OpenAI, Azure OpenAI, Anthropic, or open-source models) in production — able to reason about latency budgets, failure handling, and fallback strategies at scale across a large engineering org.

• Awareness of agentic system design (tool-calling, multi-step orchestration, single vs. multi-agent topologies) and frameworks such as LangChain / LangGraph / Semantic Kernel — enough to guide teams on when agentic patterns add value vs. unnecessary complexity.

• Ability to guide the team on responsible AI practices: prompt injection risks, output validation/guardrails, PII handling, model versioning, and auditability — especially relevant given the financial/payments domain this team operates in.

• Comfort evaluating inference cost and performance trade-offs (token usage, caching strategies, model selection between small vs. large models) when advising on AI-related architectural decisions.

• Experience mentoring engineers on AI-assisted development practices and fostering safe, consistent adoption of tools like GitHub Copilot or Code Puppy across the team.
