Overview

At Bank of America, this role is responsible for defining and leading the engineering approach for solutions at the program or portfolio level, to deliver significant business outcomes. The role focuses on continuously improving the design, quality, and reuse of the solution and delivering technology enablers that improve development efficiencies. Job expectations include familiarity with at least one area of engineering, acting as a "go to" reference across the organization, and applying knowledge to improve technical competencies through recruitment and development activities.

Within the SDLC Software Delivery Lifecycle program, this position leads portfolio product delivery strategy and execution for enterprise software delivery capabilities, ensuring the right investments, operating model, governance, and prioritization are in place to improve how internal technical users build, test, and deliver software at scale.

Within Dev Ex we are seeking an Agentic Experience & UI Framework Principal Engineer to lead the architecture and buildout of a modern UI platform that powers AI‑driven and agent‑assisted workflows across the Software Delivery Lifecycle (SDLC).

This role sits at the intersection of frontend platform engineering, AI‑assisted user experiences, and developer productivity. The engineer will define how engineers and delivery teams interact with LLM‑powered capabilities, autonomous agents, and intelligent workflows through intuitive, real‑time, and highly interactive user interfaces.

• Develop the engineering approach for the entire program/portfolio solution and work with Architecture to develop, analyze, and deliver the implementation of technical enablers.
• Lead the planning, definition, and design of complex features that span multiple teams and explore solution alternatives.
• Create ideas on designing complex technology and solution development approaches.
• Lead the technical oversight for teams in solution development, including design reviews and code within own domain.
• Define the technology tool stack for the solution within the range of internally approved and supported technologies.
• Explore state‑of‑the‑art technologies to improve development efficiencies, quality of test/QA coverage, and release management.
• Lead and be responsible for the end‑to‑end test strategy/creation/adherence, and the integration between teams for a program/portfolio solution.
• Improve the experience for our developers, making it easier to deliver industry‑leading solutions while managing work efficiently and with the right controls.
• Advance our technology platforms through innovation.
• Reduce risk and improve quality across our technology portfolio by aligning to a single enterprise architecture strategy and delivering governance that enables consistency, integration and automation.
• Define and drive the UI platform architecture for AI‑powered and agent‑assisted developer experiences.
• Build scalable frontend frameworks, component systems, and design patterns to support dynamic, AI‑driven workflows.
• Design interactive, conversational, and workflow‑centric interfaces that integrate with LLMs and autonomous agents.
• Develop real‑time user experiences (streaming responses, step‑by‑step execution, logs, agent reasoning visibility, task progress).
• Create UI patterns for human‑in‑the‑loop workflows, approvals, overrides, and task orchestration.
• Partner with AI/ML and platform teams to integrate LLMs, APIs, and agent orchestration layers into cohesive user experiences.
• Define standards for prompt‑driven UX, contextual interfaces, and adaptive UI behavior based on model outputs.
• Ensure secure, role‑aware, and governed experiences aligned with enterprise IAM/SSO.
• Drive adoption by establishing frontend standards, usability benchmarks, and developer experience best practices.

• 15+ years of engineering experience with strong focus on frontend or full‑stack platforms.
• Proven experience building developer‑facing tools, AI‑assisted applications, or intelligent workflow systems.
• Demonstrated leadership in defining architecture and scaling platforms across teams.
