• Own end-to-end system architecture, technical design and development, with significant involvement in building new platforms and modernising existing systems.
• Provide hands‑on technical leadership to a small team of approximately 2–6 engineers, driving engineering standards, code quality and delivery.
• Collaborate with global technology and business stakeholders to deliver robust, business‑critical solutions.
• Leverage modern AI-assisted development tools to improve engineering productivity and development workflows.

Key Requirements

• Strong software engineering background in Rust, C#, Java or Python. (10+ yrs)

• Demonstrated experience leading or mentoring engineers, either in a formal management capacity or as a technical lead.
