About The Position

We are seeking a visionary and hands-on Apps Development Senior Manager to lead engineering delivery for the Trade Manager Zone (TMZ) platform within the Cash Securities Settlements group, supporting the Equity Growth Initiative. This is a core engineering leadership role at the heart of a high-impact, high-throughput financial platform that processes equity trade settlements at scale. You will lead high-performing engineering teams responsible for building, maintaining, and evolving mission-critical settlement systems — driving architectural excellence, modern delivery practices, and technical transformation. Critically, you will play a defining role in embedding Artificial Intelligence and Machine Learning into the platform — from AI-assisted development and intelligent automation to predictive analytics and GenAI-powered operational tooling — accelerating delivery, elevating code quality, and future-proofing our engineering culture. This role demands deep technical expertise, strong ownership, and the ability to lead through complexity in a regulated, fast-paced financial environment.

Requirements

• Data Engineering: Strong understanding of data pipelines, streaming data processing, and data quality patterns in high-volume environments
• Intelligent Automation: Applying ML to automate exception handling, anomaly detection, and operational workflows in financial platforms
• AI Governance: Familiarity with responsible AI principles — explain ability, auditability, and compliance in regulated environments
• Cloud-Native Engineering: Hands-on experience with AWS, Kubernetes, and Docker for scalable, containerized deployments
• CI/CD Pipelines: Strong proficiency in building and maintaining CI/CD pipelines aligned to Citi Engineering Excellence Standards
• Trunk-Based Development: Feature flags, progressive delivery, and continuous integration as core delivery practices
• Observability & Monitoring: Experience with production monitoring, distributed tracing, intelligent alerting, and SRE practices
• Secure Engineering: AI-augmented vulnerability assessments, secure coding standards, and compliance in regulated financial environments
• Agile Delivery: Strong experience in Agile/SAFe frameworks — backlog management, sprint delivery, and cross-team dependency management
• Bachelor’s degree/University degree or equivalent experience
• Stays close to the code — actively participates in design, review, and technical problem-solving alongside the team.
• Thinks AI-first — actively seeks opportunities to apply AI and GenAI to engineering and operational challenges, not just product features.
• Owns outcomes — takes full accountability for platform quality, reliability, and delivery commitments.
• Thrives in complexity — comfortable navigating the technical and operational complexity of mission-critical financial systems.
• Raises the bar — consistently pushes for higher engineering standards, better test coverage, cleaner architecture, and more resilient systems.
• Embraces AI pragmatically — identifies high-value opportunities to apply AI/ML to real platform problems, without losing sight of engineering fundamentals.
• Inspires curiosity — creates an environment where engineers are excited to learn, experiment, and grow with AI.
• Builds great teams — invests in people, creates psychological safety, and develops the next generation of engineering talent.

Nice To Haves

• Experience with real-time ML model serving in low-latency, high-throughput environments (e.g., feature stores, online inference).
• Familiarity with Retrieval-Augmented Generation (RAG), vector databases (e.g., Pinecone, Weaviate), or AI agent frameworks (e.g., LangChain, AutoGen).
• Knowledge of MLOps practices — model versioning, deployment pipelines, and monitoring in production.
• Understanding of AIOps — AI-driven incident management, anomaly detection, and intelligent observability.
• Knowledge of equity trade lifecycle, settlement mechanics, or cash securities processing.
• Understanding of regulatory compliance frameworks relevant to securities settlement (e.g., T+1, CSDR).
• Experience with performance profiling and tuning of JVM-based applications (Kotlin/Java) under high load.
• Knowledge of risk management, reconciliation, and exception handling patterns in settlement workflows.
• Familiarity with prompt engineering and fine-tuning strategies for LLMs in an enterprise context.
