• Proactively identify technical risks, dependencies, and optimisation opportunities, and drive mitigation strategies.
• Support and resolve production incidents and complex technical issues as a subject matter expert.
• Lead vendor and technology evaluations, including Proof of Concepts (PoCs), and guide adoption of tools, frameworks, and platforms.
• Champion continuous improvement by enhancing development processes, engineering practices, and productivity.
• Mentor and coach engineers across the team, fostering technical growth and best engineering practices.
• Drive knowledge sharing initiatives (tech talks, brownbags, documentation) and build strong engineering culture.
