Responsibilities

• Build and maintain the full stack applications behind k‑ID's newest products, from first release through to production scale
• Write the detailed specifications that agents build against, and review the resulting code to a high standard
• Iterate on and improve your own development rig so that each build is better than the last
• Contribute to technical design and implementation decisions across frontend, backend, APIs, and data flows

• Develop responsive, reliable, and maintainable applications using Next.js and related technologies
• Improve and support production systems by identifying issues, debugging effectively, and shipping fixes with care
