- Use AI-assisted engineering tools (e.g., GitHub Copilot, Claude Code) to accelerate delivery while maintaining code quality standards.
- Participate in sprint planning and Agile ceremonies, proactively raising risks, dependencies, and delivery trade-offs.
- Review code, mentor engineers, and champion clean, secure, well-tested, maintainable front-end practices. Who You Are
- Proactive and ownership-driven, identifying issues and opportunities early and driving them through to resolution.
- A clear communicator who can explain technical decisions, trade-offs, and risks to engineers and non-technical stakeholders.
- Comfortable managing expectations in a client-facing environment, including constructive pushback and transparent progress updates.
- Delivery-focused, balancing speed with quality, reliability, and maintainability.
- Collaborative and supportive, raising team standards through thoughtful reviews, knowledge sharing, and mentoring. Minimum Qualifications (Must-Have)
