Offer description

At TNC, we empower customer workforce’s to transform children’s lives. Our all-in-one platform helps schools, trusts, and nurseries stay compliant, raise standards, and reduce staff workload — all through intuitive, powerful software.

You’ll work across front‑end and back‑end systems, leading the delivery of new features and integrations while maintaining high standards of code quality, performance, and reliability.

Alongside hands‑on development, you’ll mentor and grow a team of Ruby developers, establish best practices, and improve delivery processes. You’ll collaborate closely with product and engineering stakeholders to solve complex problems and evolve the platform.
