• Hands-on experience using AI coding agents in real projects
• Experience with agent-based workflows (sub-agents, agent teams, orchestration)
• Strong practical skills in context engineering and prompting for coding tasks
• Your workflow has been primarily AI-driven (you write little/minimal code manually and focus on direction, context, validation, and quality)
• Strong problem-solving and collaboration skills

Nice to Have

• Cross-stack experience (frontend + backend)
• Experience with testing automation, cloud, DevOps
• Experience creating reusable prompts / agent playbooks
• Experience mentoring others in AI-first development

What You’ll Get in the Team

• Work in the Innovation Center on meaningful, fast-moving initiatives
