• Design and maintain Java-based APIs and microservices, including REST, OpenAPI, GraphQL, and gRPC-based services
• Champion engineering best practices across code quality, testing (unit/integration), CI/CD, and observability
• Mentor and lead junior and mid-level engineers, setting clear standards through code reviews and technical guidance
• Independently identify, scope, and propose solutions to complex technical problems with minimal direction
• Partner closely with Investment Banking stakeholders, product managers, and cross-functional technology teams
• Optimize systems for performance, scalability, resiliency, and low-latency operation
• Participate actively in Agile ceremonies, contributing to planning, execution, and continuous improvement

Required Qualifications

• 12+ years of hands-on experience building enterprise-grade backend systems
• Strong expertise in Java, Spring Boot, microservices architecture, and distributed systems
• Proven experience with Kafka and event-driven architectures in high-throughput environments
• Solid experience with SQL and data modeling, including relational and NoSQL systems
• Hands-on experience with AWS, containerized deployments (EKS, Docker, Kubernetes), and CI/CD pipelines
• Demonstrated ability to design fault-tolerant, highly available systems
• Excellent communication skills with the ability to explain complex technical concepts to both technical and non-technical stakeholders

Seniority & Leadership Expectations

• Independently architects multi-service, cloud-native solutions, clearly articulating trade-offs and design rationale
• Demonstrated track record of leading engineering delivery end-to-end
• Proactively identifies performance, scalability, and reliability risks before they impact production
• Sets a strong example for code quality, maintainability, and operational excellence
• Comfortable operating with high ownership and accountability in a fast-paced environment

Preferred / Nice-to-Have Experience

• Exposure to Investment Banking or Financial Services domains
• Experience with Python (FastAPI) in addition to Java
• Knowledge of the extended Apache ecosystem
• Experience with CRM platforms (e.g., Salesforce)
• Familiarity with BI and analytics tools (Tableau CRM, Cognos, Power BI)
• Exposure to ETL / data engineering platforms (Databricks, StreamSets, MuleSoft)
• Front-end exposure (Angular, React, TypeScript) is a plus
