The Office of the CTO (OCTO) is an engineering team tasked with company-wide engineering acceleration:

You'll also find and fix structural, organizational, or technical debt blockers. This is a really exciting and versatile role, giving you broad responsibilities and the chance to work closely with the CTO.

This is an office-flexible position requiring three days a week in-office in Edinburgh, UK.

  • Define technology roadmaps and architectural standards; drive adoption across [Employer hidden]
  • Write code (both with and without AI assistance), and conduct code reviews
  • Proactively identify, prioritize and propose remediation for tech debt
  • Mentor and guide software engineers and architects on best practices
  • Evaluate and select appropriate technologies and frameworks
  • Collaborate with product management and business stakeholders
  • Troubleshoot and resolve complex technical issues

Who You Are

  • Expertise in cloud platforms (AWS strongly preferred)
  • Strong internet and internal networking experience
  • Experience building multiple production / client-facing applications
  • Experience with customer-facing API design, authentication, and authorization
