• Solid working knowledge of C#, with the ability to guide and support Unity‑based development teams from a leadership perspective.
• Demonstrated experience owning system architecture and making technical decisions that balance delivery speed with long‑term scalability.
• Experience designing and integrating AI‑enabled services using external APIs and modern integration patterns.
• Comfortable working across cloud‑based systems, APIs, data flows and JSON‑driven architectures.
• Experience running code reviews, mentoring engineers and raising engineering standards across a team.
• Strong delivery mindset, with experience collaborating closely with project or product management.
• Confident communicator, able to explain technical concepts clearly to non‑technical stakeholders.
