Apps Dev Tech Lead Analyst at Citigroup in Jersey City, NJ

Apps Dev Tech Lead Analyst Location: Jersey City New Jersey United States Apps Development Senior Manager Trade Manager Zone Platform | Cash Securities Settlements | Equity Growth Initiative About the Role 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. Responsibilities: 1. Software Development & System Design Architect, design, develop, and maintain robust, scalable, and high-performance applications supporting equity trade settlement workflows on the Trade Manager Zone platform. Lead the design of distributed, fault-tolerant, real-time systems capable of handling high-volume, low-latency trade processing across global markets. Champion the use of AI-assisted coding tools (e.g., GitHub Copilot or equivalent GenAI tools) to accelerate developer productivity, reduce toil, and improve code quality. Drive adoption of trunk-based development practices to enable continuous integration and rapid, safe delivery. Ensure code is clean, maintainable, and testable — adhering to SOLID principles, design patterns, and platform engineering standards. Actively contribute to hands-on coding, code reviews, and refactoring to maintain high engineering standards across the team. Own the technical design of key platform components, producing clear architecture documentation and decision records. 2. Engineering Excellence & AI-Driven Quality Champion Test-Driven Development (TDD), Behavior-Driven Development (BDD), and high unit test coverage as non-negotiable engineering standards. Introduce AI-powered code review tooling to complement human reviews — catching security vulnerabilities, anti-patterns, and performance issues at scale. Apply predictive quality analytics to identify high-risk code changes before they reach production. Drive the adoption of automated testing frameworks across unit, integration, regression, and end-to-end test layers, including AI-assisted test generation. Implement and enforce secure coding practices, augmented by AI-driven vulnerability scanning, performing assessments and ensuring compliance with financial industry security and regulatory standards. Advocate for infrastructure as code, continuous monitoring, and AI-assisted observability (e.g., anomaly detection, intelligent alerting, root cause analysis) to enhance platform reliability. Embed CI/CD pipelines and DevOps practices deeply into the team's delivery workflow, aligned to Citi Engineering Excellence Standards. Drive a culture of zero-defect engineering — proactive quality ownership from design through to production. 3. Advanced AI & Data Integration Lead the integration of AI and ML capabilities into the Trade Manager Zone platform — including intelligent exception handling, anomaly detection, predictive settlement failure analysis, and automated reconciliation workflows. Leverage Large Language Models (LLMs) and GenAI APIs to embed intelligent capabilities into platform operations — such as natural language interfaces for trade operations, automated summarization of settlement exceptions, and AI-driven decision support. Partner with data engineers and ML practitioners to design and operationalize AI/ML pipelines that consume real-time trade data and deliver actionable intelligence. Apply advanced data integration patterns to ensure high-quality, low-latency data flows across platform components, supporting both operational and analytical AI use cases. Evaluate and adopt AI/ML frameworks and tooling appropriate for high-throughput financial systems, ensuring models are production-grade, explainable, and compliant with risk and governance standards. Champion responsible AI practices — ensuring fairness, auditability, and regulatory alignment in all AI-driven platform capabilities. Drive the team's AI adoption roadmap — identifying high-value opportunities to apply GenAI, ML, and intelligent automation to real platform engineering and operational challenges. 4. Platform & Domain Expertise Develop deep understanding of equity trade lifecycle, settlement mechanics, and cash securities processing to make informed technical decisions aligned with business needs. Partner with business analysts, product owners, and operations teams to translate complex settlement workflows and regulatory requirements into robust technical solutions. Ensure platform components meet SLA, SLO, and SLI targets for availability, throughput, and latency in a mission-critical environment. Collaborate with downstream and upstream system owners across the Cash Securities Settlements ecosystem to ensure seamless integration and data integrity. Drive continuous platform modernization — improving maintainability, scalability, and operational efficiency of TMZ components. 5. Technical Leadership & People Management Lead, mentor, and grow a team of engineers — setting high engineering standards and fostering a culture of craftsmanship, AI curiosity, accountability, and continuous learning. Mentor engineers on AI tool usage, prompt engineering, and responsible AI practices, building internal AI literacy across the team. Partner with architects, platform engineers, and cross-functional teams to design scalable, distributed, and AI-ready systems. Collaborate closely with DevOps, SRE, and infrastructure teams to optimize deployments, observability, and production resilience — leveraging AIOps capabilities. Lead technical discussions, architecture reviews, and design sessions — providing clear guidance on engineering decisions, AI integration patterns, and trade-offs. Drive capacity planning, technical roadmap execution, and engineering delivery commitments for the TMZ platform. Represent the engineering team in stakeholder forums, providing transparent updates on delivery progress, risks, and technical health. Skills and Qualifications Must-Have Skills 1.
