About the role

Key responsibilities & impact

Own frontend technical delivery for assigned AI Accelerator projects, from rapid prototyping through production-adjacent hardening.
Build React and TypeScript experiences for chat, copilots, workflow automation, agent supervision, prompt/configuration screens, data apps, and evaluation/feedback workflows.
Design intuitive interfaces for streaming AI responses, tool execution status, verifiable source references, citations/provenance, confidence displays, multimodal review, human approval steps, and error recovery.
Build human-in-the-loop experiences that make living context inspectable and correctable by humans, including review, diff, approval, correction, and provenance workflows for agent-maintained knowledge.
Integrate frontend experiences within BMS-aligned consuming apps and services.
Define frontend architecture patterns, reusable components, and starter templates that help future Accelerator pods move faster.
Partner with designers to translate designs, mock ups and living prototypes into accessible, polished, production-quality components and workflows.
Collaborate with AI, App/Cloud, and Data Engineering teams to define clean API contracts, streaming patterns, auth flows, and telemetry boundaries.
Build frontends that align with enterprise standards for accessibility, security, input validation, safe rendering, performance, and maintainability.
Support AI Accelerator agile cycles of six two-week sprints over a 12-week cycle by building, testing, validating, and hardening frontend product increments each sprint.
Use coding agents and AI-assisted development tools effectively while maintaining strong validation, security, and code quality practices.
Write and maintain frontend test suites using tools such as Vitest/Jest, React Testing Library, Playwright, Cypress, or similar frameworks.
Design evaluation interactions and evaluator-facing workflows that allow users and SMEs to score outputs, flag issues, compare variants, capture rationale, and feed lessons back into product and model improvements.
Instrument user feedback, usage telemetry, and evaluation touchpoints so AI teams can learn where workflows succeed, fail, or need guardrails.
Contribute to GitHub-based CI/CD, build/release pipelines, environment configuration, and deployment support in partnership with platform teams.
Partner closely with product owners, scientists, business stakeholders, and engineers to translate ambiguous AI opportunities into usable product experiences.
Continuously refine frontend priorities and backlog items based on stakeholder feedback, performance results, and lessons learned during MVP development.
Provide technical coaching through code reviews, design reviews, architecture guidance, and pragmatic delivery standards.
Help communicate frontend trade-offs clearly to technical and non-technical stakeholders, especially when balancing speed, usability, risk, and enterprise readiness.
