Key responsibilities 1. Own data quality monitoring (about 40%) - Design, build and maintain automated checks on key activity and reference datasets: volumes, rates, freshness, completeness and distribution shifts. - Set baselines and alert thresholds so the team is told about unexpected changes — for example, a sudden drop in clinicians opening emails, a spike in bounces, or missing specialty values. - Tune alerts to keep noise low; every alert should be worth looking at. - Maintain a data quality dashboard and report trends and recurring issues in the team's monthly metrics. 2. Own data quality investigations (about 30%) - Triage each alert or reported issue: confirm it is real, size the impact and set a priority. - Start the investigation and pull in the right people — data engineering, AppDev, the data architect, reference data owners and business stakeholders. - Trace issues to root cause across source systems, pipelines and reference tables. - Document findings, impact and resolution in a shared issue log and in Confluence, so recurring issues become known patterns. - Communicate status clearly to affected stakeholders until the issue is closed. 3. Pre-deployment Data Acceptance Testing (about 30%) - Collaborate with Application Development and data engineering teams on which datasets each release should and should not affect. - Run pre- and post-deployment data comparisons (row counts, key metrics, schema and value checks) to confirm only expected data changes. - Give formal data sign-off, or raise a blocker, for releases - particularly AppDev deployments where downstream data impact is not expected. - Turn repeat checks into reusable, automated test suites over time. - Feed lessons from incidents back into release checklists and change-request reviews. Qualifications Required - 3+ years in data quality, data analysis, data QA or analytics engineering. - Strong SQL: comfortable comparing large datasets, writing reconciliation queries and profiling data. - Hands-on experience setting up data monitoring or alerting (dbt tests, Great Expectations, Soda, or custom SQL/Python checks). - Hands-on experience with AI coding tools like Claude code, OpenAI Codex CLI, Antigravity CLI, or similar. - Ability to articulate and write requirements for automations, query schedules, and data quality alerts. - Experience testing data around software releases, ideally working alongside application developers. - Methodical root-cause analysis and clear written documentation. - Strong attention to detail - Confident coordinating with people across teams and time zones without direct authority. - Professional working proficiency in English, written and spoken; Spanish an asset. - Able to work with significant overlap with Eastern Time (Toronto). Preferred - Python for automation and anomaly detection. - Experience with marketing or engagement data (email sends, opens, clicks, bounces), ideally in healthcare or pharma communications. - Familiarity with reference data, master data or data governance practice (e.g., DAMA-DMBOK). - Experience using Jira/Confluence, google suite, - Knowledge of CRM data (e.g., Zoho) and privacy-aware handling of HCP data. How you work - Takes ownership and drives issues to closure on their own. - Stays calm and structured when the problem is ambiguous. Breaks down tasks into manageable chunks and iterates. - Prefers automating a check over repeating it by hand. - Flags what they find early and plainly, even when the news is unwelcome. - Uses AI to help you get things done faster.
