Working at Citi is far more than just a job. A career with us means joining a team of more than 230,000 dedicated people from around the globe. At Citi, you’ll have the opportunity to grow your career, give back to your community and make a real impact.
Key Responsibilities
1. Mainframe Modernisation & Platform Transformation
-
Own and drive end-to-end migration of legacy Mainframe workloads (COBOL, JCL, CICS, IMS, DB2/z) to modern Java-based microservices deployed on enterprise container platforms (OpenShift / Kubernetes).
-
Conduct application assessments to identify migration candidates, define target-state architectures, and produce sequenced migration roadmaps with risk registers and rollback plans.
-
Establish reusable migration patterns, tooling, and runbooks to accelerate successive migration waves.
-
Leverage AI-assisted code translation tools (e.g., autonomous AI coding agents such as Devin) to automate COBOL-to-Java conversion at scale, with human-in-the-loop review gates.
-
Validate functional parity post-migration through automated testing strategies (unit, integration, regression, performance).
2. Technology Operating Cost Reduction
-
Identify and quantify cost-reduction opportunities across MIPS consumption, software licensing, infrastructure footprint, and operational overhead.
-
Build and maintain a technology cost model; track savings realisation against committed targets on a monthly cadence.
-
Drive rationalisation of redundant systems, decommission end-of-life platforms, and consolidate tooling to reduce Total Cost of Ownership (TCO).
-
Partner with Finance and Vendor Management to renegotiate contracts and optimise spend through right-sizing, reserved capacity, and FinOps practices.
-
Introduce engineering efficiency metrics (deployment frequency, lead time, MTTR) to demonstrate productivity gains that translate to measurable cost avoidance.
3. Hands-On Engineering & Technical Leadership
-
Actively contribute to code reviews, architecture design sessions, and technical spike investigations as a practitioner — not just an observer.
-
Define and enforce engineering standards: coding conventions, API design (REST / gRPC), CI/CD pipeline standards, and security-by-design principles.
-
Lead adoption of modern Java ecosystem tooling: Spring Boot, Spring Cloud, Maven/Gradle, JUnit 5, Mockito, and Testcontainers.
-
Oversee containerisation and orchestration using Docker, Helm, and OpenShift / Kubernetes; govern CI/CD pipelines built on Tekton and Harness.
-
Ensure observability best practices: structured logging (Splunk), distributed tracing (OpenTelemetry ), and metrics dashboards (Prometheus / Grafana).
-
Govern secrets management via HashiCorp Vault and enterprise M2M authentication standards (OAuth 2.0 / OIDC).
4. Generative AI & Agentic Development
-
Champion the adoption of enterprise AI tooling across engineering teams, including:
-
Secure LLM API Gateways (equivalent to Azure OpenAI/litellm / Vertex AI enterprise proxies) for governed, audited access to large language models.
-
AI-powered developer workspaces for productivity acceleration (e.g., GitHub Copilot, Devin, Claude, or equivalent enterprise AI coding assistants).
-
AI-driven automated code review frameworks — embedding GenAI-powered PR and end-to-end review into CI/CD workflows.
-
Enterprise AI Agent Platforms (OpenShift-based) for secure, scalable deployment and lifecycle management of AI agents in a regulated environment.
-
Drive agentic development using Google ADK (Agent Development Kit) and MCP (Model Context Protocol) to build multi-agent workflows that automate test generation, documentation, incident triage, and code migration tasks.
-
Evaluate and pilot AI coding assistants (Devin and equivalents) for autonomous code generation and refactoring; establish guardrails and human-in-the-loop review processes.
-
Ensure all AI tooling usage complies with data classification policies, enterprise authentication standards, and AI governance frameworks applicable in a regulated financial services environment.
5. People Leadership & Stakeholder Management
-
Lead, mentor, and grow a team of 4-10 engineers across multiple squads, fostering a high-performance engineering culture.
-
Represent the India technology team in global forums, steering committees, and executive briefings; communicate programme status, risks, and decisions with clarity.
-
Build strong partnerships with global counterparts across the US, UK, and APAC to align on architecture decisions and delivery priorities.
-
Drive Agile / SAFe delivery practices: sprint planning, backlog grooming, retrospectives, and PI planning.
Required Qualifications
Education & Experience
-
Bachelor's or Master's degree in Computer Science, Information Technology, Engineering, or a related technical discipline.
-
13–18+ years of progressive software engineering experience, with at least 5-8 years in a senior technical leadership role (Tech Lead, Staff Engineer, principle).
-
Demonstrated experience leading or significantly contributing to at least one large-scale Mainframe modernization or legacy platform migration programme.
-
Prior experience in financial services, banking, or a similarly regulated industry strongly preferred.
