• Comfortable working in performance‑oriented, production‑critical environments with high‑throughput & low talent systems.

Soft Skills

• Strong problem‑solving skills and a proactive, collaborative working style.
• Ability to communicate well with engineers and data science partners.

Academic Background

• Computer science, computer engineering or a related field is preferred.
