• Automation culture – Champion “Automation Everywhere”, automated specification, development, testing, CI/CD, monitoring, reporting and patching.

• Team leadership (≈ 30 %) – Mentor a team of 10-20 engineers, set career pathways, run regular 1‑on‑1s and foster a blameless post‑mortem culture.

• Strategic partnership – Work closely with the CTO, product and AI Adoption teams to align platform road‑maps with market demands and emerging security standards.
