Lead Full Stack Engineer - Assistant Vice President

Role purpose

This is a hands-on role for an engineer who leads by building. You'll lead engineering on a multi-year programme to modernize and migrate a large portfolio of middle-office applications to AWS. You'll write production code across primarily front end (ReactJS front ends, TypeScript, NodeJS, npm/pnpm etc., DevOps pipelines). You'll also set up and run the UI team's AI-augmented delivery model, using AI agents and assistants to speed up discovery, code conversion, testing and deployment while meeting the control standards a global custodian needs.

Key responsibilities

Hands-on UI engineering

• Build ReactJS front ends that replace legacy desktop and GWT/PowerBuilder UIs, including state management, component libraries, SSO/MFA integration and accessibility.
• Build and maintain CI/CD pipelines (Harness or similar), infrastructure-as-code (Terraform), containerization (Docker/Kubernetes), secrets management (Vault/CyberArk) and observability.
• Write reference implementations, templates and starter projects that the rest of the team and AI agents follow.
• Do daily code reviews and pair with engineers, and debug production-grade issues yourself.

Engineering leadership

• Lead the modernization engineering team and set standards for architecture, code quality, testing and release.
• Own technical delivery plans, estimates and release quality, working with Architecture, Platform, Data, QE and the existing application support teams.
• Lead engineering for cutover, parallel runs and handover to run teams.

AI-augmented delivery

• Use AI tools hands-on every day (for example GitHub Copilot, Devin, Blitzy and agent frameworks), and lead from your own experience of what works.
• Build agent workflows, prompt libraries and codebase knowledge context (knowledge graphs, MCP connections to Jira, Confluence, ServiceNow and SharePoint).
• Apply AI to reverse-engineering legacy code, generating specs, converting code and generating tests.
• Track AI productivity and quality (throughput, defect rates, rework, cost per migrated application) and report outcomes to leadership.

Risk, controls and governance

• Put human review checkpoints, audit trails and secure-coding gates on all AI-generated code, in line with State Street technology risk, information security and model governance policies.
• Make sure business logic extracted by AI is checked by subject-matter experts and confirmed through reconciliation before go-live.

People and capability

• Hire, coach and grow a permanent full-stack engineering team, and build AI fluency across the team.
• Manage vendor and temporary capacity and make sure knowledge transfers to permanent staff.

Required experience and skills

• 12+ years in software engineering, still actively coding, with 5+ years leading engineering teams on modernization or cloud migration programmes.
• ReactJS: strong in modern React (hooks, TypeScript, Redux or similar), component design, testing (Jest/React Testing Library) and building data-heavy enterprise UIs.
• DevOps: practical experience with CI/CD (Harness, Jenkins or GitHub Actions), Terraform, Docker, Kubernetes/ECS/EKS, Git workflows, automated testing and quality gates.
• AWS: compute, networking, IAM and managed services, and how to design for HA/DR.
• AI: proven hands-on use of AI coding assistants and agents in delivery, with measurable results.
• Comfort reading and reverse-engineering legacy code
• Experience delivering in a regulated financial services environment.

Preferred

• Knowledge of investment servicing or middle-office areas: trade capture, confirmation, settlement, collateral, reconciliation, investment accounting.
• Experience building MCP servers, knowledge graphs or retrieval-augmented context for engineering agents.
• AWS Professional-level or equivalent certification.
