- Work with client architecture, security and governance teams on access, retention and compliance decisions.

- Identify new growth opportunities within the account, such as further migration domains, data platform and AI-enabled consumption initiatives, by building relationships with client architects and business stakeholders.

- Recommend solutions and shape proposals for these opportunities, working with Altimetrik account, sales and delivery leadership on scope, approach, estimates and commercials.

- Mentor engineers and support estimates, scope and risk management.

- 12+ years in data engineering and architecture, with 4+ years of hands-on Snowflake experience.

- Proven Hadoop (Cloudera, Hive, Spark) to cloud data platform migration delivery.

- Strong SQL, Python and Spark; working knowledge of Snowpark, orchestration and CI/CD for data pipelines.

- Experience with data modeling, lineage and reconciliation in a regulated environment.

- Experience leading distributed teams and presenting to senior client stakeholders.
