#Technical Leadership Lead and mentor a team of backend engineers across multiple functional domains. Provide technical direction and ensure alignment with architecture standards and engineering best practices. Review solution designs, code quality, and implementation approaches - promoting clean architecture, resilient microservices, and AI-enhanced development patterns. Guide the team in diagnosing complex technical challenges, using both traditional analysis and AI-powered debugging or observability tools. Support planning, estimation, and technical decision-making within the engineering team. Backend Architecture & Development Design and develop backend services using Java and modern backend frameworks (e.g., Spring Boot). Define and implement microservices-based architecture and API-driven systems. Ensure backend services are scalable, secure, resilient, and maintainable. Drive best practices in backend development, including maintainable system design, automated testing, code quality, API governance, performance optimization and documentation. Work closely with DevOps teams to support CI/CD pipelines, incorporate intelligent automation, and ensure stable, secure deployment environments. Integrate AI-assisted development practices into coding, testing, documentation, code reviews, and defect prevention workflows. #Banking & Payment Domain Design backend systems supporting banking products and financial transaction processing. Build and maintain services related to payments, card processing, financial operations, and core banking functions. Ensure backend implementations comply with financial industry standards and security requirements. Collaborate with business and product teams to translate banking and financial requirements into technical solutions. #Client Collaboration & Delivery Work directly with client stakeholders, architects, and product owners to understand business processes, requirements and define technical solutions. Challenge and clarify requirements with curiosity dig deep into the "why" behind business needs. Participate in architecture discussions and technical workshops with client teams. Communicate technical designs, trade-offs, and solutions clearly to both engineering teams and non-technical stakeholders. Support project delivery by ensuring technical risks are identified and mitigated early.
