  • Working knowledge of OAuth 2.0 and modern authentication/authorisation patterns.
• Database Knowledge:
  • Proficiency with relational databases, specifically Postgre
    
    SQL and MySQL.
  • Comfortable writing complex queries, managing schema design, and optimising database performance.
• Candidates should be familiar with, or enthusiastic to work across, our core suite of languages and frameworks:
  • Python — primary backend language.
  • React — front‑end UI framework.
• Candidates must also be familiar with Cloud Hosting and Storage:
  • Microsoft Azure, Amazon — cloud infrastructure, services, and deployment pipelines.
• The following skills are not essential but would be considered a strong advantage:
  • Microsoft Azure — cloud infrastructure, services, and deployment pipelines.
  • Linux & Virtualisation — administration, scripting, and virtualised environments.
  • Dynamics 365 — integration experience with Microsoft Dynamics 365 for CRM or operational workflows.

• A minimum of 5 years of professional experience in a software development role, with demonstrable time spent at a senior level.
• A track record of delivering complex, multi‑component software projects end to end.
