Overview
How You’ll Make an Impact at Epsilon. The Business Analysis Lead (Data Warehouse) role combines technical skill with client-facing duties within the Engineering department. You will work directly with clients to collect data requirements, examine their data, and develop mapping rules for developers. You will analyze and report data findings and provide ongoing support to internal teams, acting as a trusted advisor for the Data-warehouse team and encouraging collaboration.
In this role, you will lead technical prioritisation for custom solutions, facilitate data discovery workshops, and promote enablement through documentation and training. You will advocate for risk prevention, data privacy, and security, alongside ongoing process improvement. Working from our London office at least four days a week ensures close coordination with local market dynamics and global initiatives.
What You’ll Achieve
- Lead and facilitate technical data discovery and requirements workshops with clients and internal collaborators; translate implicit needs from non-technical participants into implementable specifications.
- Analyze client data and build scalable integration and process solutions with strong consideration for privacy, security, and operational risk.
- Address client objections to sending first-party data and explain privacy controls, minimization, and protection measures; escalate sophisticated privacy questions to legal or privacy teams when needed.
- Serve as the local market representative and main contact for blocking issues with Data Warehouse and Identity Analytics leadership; advocate for local needs while aligning with the global strategy.
- Spearhead data onboarding expansion into new and emerging markets, coordinating cross-functional teams to remove blockers and define repeatable patterns.
- Identify, propose, and lead process and tooling improvements that enhance efficiency, quality, and scale.
- Create, maintain, and present first‑party data trainings and enablement content as part of onboarding and ongoing enablement programs for local market teams.
- Develop and update internal user documentation and training resources covering architecture, data flows, governance to support scalability and effective communication.
- Advocate for clear RACI models across projects; provide feedback and drive cross‑team development, accountability, and process enablement.
- Build and maintain positive relationships with internal and external partners to understand partnership needs and ensure successful outcomes.
Who You Are
- 8+ years of experience in data onboarding, business systems analysis, data solutions engineering, or similar roles (or equivalent experience).
- Experience prioritising technical solutions with presales or solution teams, and leading technical discovery workshops.
- Intermediate SQL skills and strong understanding of relational database design and data warehousing concepts/architecture.
- Familiarity with ETL processes, file transfer methods, and production data onboarding pipelines.
- Comfortable working in Linux environments; familiarity with Python and Shell scripts is an advantage.
- Experience with data privacy frameworks and regulations (e.g., GDPR, CCPA) and applying privacy‑by‑design principles in solutioning.
- Excellent written and verbal communication, with experience crafting user documentation, trainings, and presentations at scale.
- Track record of influencing multi-functional teams and advocating for process governance (RACI, SLAs, change control).
