- Translate customer engagement and CRM data requirements into actionable data models and pipelines that power Braze and other platforms.
- Work with customer events, user attributes, identity resolution, and data synchronisation to support personalised customer experiences.
- Collaborate with Data, Analytics, CRM, and CDP teams to align technical solutions with client requirements and business goals.
- Provide technical leadership, guidance, and best practices to engineers and help drive continuous improvement.
- Identify opportunities to use AI tools, automation, and emerging technologies to improve engineering productivity and data workflows.
- Support multiple client engagements, communicate technical recommendations clearly, and adapt to changing priorities.
What Makes You a Great Fit
- 5+ years of experience in data engineering, data platforms, or a similar technical role, with strong ownership of architecture, implementation, and optimisation.
- 4+ years of hands-on experience with SQL, data modelling, and ETL/ELT processes.
- 2+ years of experience using Python to build data applications and transformations.

- Strong understanding of data architecture, pipeline design, database performance, testing, and data quality.
- Experience translating business and customer engagement requirements into reliable data solutions.
- Strong communication skills, with the ability to explain complex technical concepts to non-technical stakeholders.
- Experience working in an agency or consulting environment, managing multiple clients and adapting to changing priorities.
- A proactive approach to problem-solving, continuous learning, and using AI tools to improve day-to-day productivity.
- Ability to work independently while collaborating effectively with cross-functional teams.
