Ensure seamless collaboration, clear communication, and consistent operational standards across a distributed team. Contribute to the long‑term technical strategy for data operations including modernisation efforts.
  

• 
  
• Demonstrable hands‑on experience in a production support, site reliability, or data operations role within a large‑scale data environment.
  
• Experience with data distribution platforms (e.g. Ab Initio & Spark centric solutions like AWS Glue & EMR), including deep understanding of ETL/ELT workflows & integration into data platforms like Snowflake.
  
• Extensive experience with scheduling platforms such as Control‑M, including complex scheduling, dependencies, and managing a large batch environment.
  
• Working knowledge of IBM Sterling FileGateway or similar file transfer (MFT) solutions would be beneficial (e.g. AWS Transfer Family).
  
• Deep knowledge of AWS and its data‑related services, including knowledge of open‑source, cloud‑first data‑pipeline orchestration capabilities like Apache Airflow.
  
• Proficiency in Shell scripting & Python for automation and system administration.
  
• Proven ability to manage highly sensitive and critical data pipelines, with a strong understanding of security and compliance requirements.
  
• Demonstrated experience working effectively with both onsite and offshore teams, ensuring seamless operational handoffs and knowledge sharing.
  
• Excellent communication skills, with the ability to articulate complex technical issues to both technical teams and business stakeholders.
  
• Experience with DevOps or DataOps principles and practices is essential.
