Description

Key Exciting Responsibilities:

• Agent Orchestration: Design, own, and continuously improve the pipelines through which AI development agents perform coding, documentation, and refactoring on secure, maintainable, approved platforms. Set the team's standards for supervising agent output, code quality, and version control, and

own the prompt libraries, agent skills, and evaluation datasets that keep agent workflows reliable.

• Architecture: Lead the design of modular, cost-aware architectures for scale and performance that agents can implement. Drive technical feasibility and security reviews early in the PDLC, ensure adherence to Platform standards (e.g., TID, EMS, Modus, File Service), and lead prototype design reviews that turn product requirements into execution plans. Author and review ADRs, and weigh in on architectural decisions that span multiple services or teams.

• Feature Delivery and Testing: Deliver complex, end-to-end features across frontend (e.g., UI, accessibility) and backend services (e.g., APIs, authentication, messaging, infrastructure) with minimal guidance. Own testing strategy and frameworks for your area, including unit, integration, and E2E tests with explicit coverage targets and automated, continuous testing.

• Technical Leadership & Mentorship: Mentor and coach other engineers on agentic development practices, code review, and system design. Lead code and design reviews, share reusable patterns across teams, and help less experienced engineers grow.

• Business Outcomes: Own applicable KPIs for your area, ensuring your work and your team's technical decisions are directly tied to business outcomes.
