Octus is seeking a Data Quality Analyst to design and implement the company's first standardized data quality framework, ensuring consistency, reliability, and trust across all analytical and client-facing datasets. This role is highly hands-on and sits at the intersection of data quality, data operations, and data governance. The analyst will collaborate closely with the data operations team, dataset owners, and engineers to define quality standards, implement automated checks, and embed data quality into Octus's modern data stack.

Key responsibilities include designing and implementing a scalable data quality framework covering accuracy, completeness, timeliness, and consistency across datasets. The analyst will define reusable data quality patterns and testing approaches aligned with business requirements, establish prescriptive standards for data modeling, transformations, and ingestion, and build and maintain automated data quality checks using SQL, dbt tests, and similar frameworks. Additionally, the role involves implementing business rule validations, anomaly detection, and functional data tests, embedding quality checks directly into transformation pipelines and CI/CD workflows, and partnering with dataset owners to define dataset-specific quality expectations. The analyst will also support the adoption of data quality tooling, best practices, and documentation across teams, act as a subject-matter expert for data quality within the data operations ecosystem, identify, triage, and help resolve data quality issues across pipelines and downstream consumers, contribute to data quality monitoring dashboards and reporting, support root-cause analysis and preventative improvements, and document data quality standards, testing approaches, and framework usage.

The ideal candidate will have strong hands-on experience with SQL, experience working with dbt or similar transformation/testing frameworks, proficiency with Git and collaborative development workflows, experience designing or implementing data quality checks, validations, or testing frameworks, and a solid understanding of modern data warehouse concepts. The ability to work cross-functionally with technical and non-technical stakeholders is essential. Candidates must be legally authorized to work in the country where the position is located.

The company fosters a culture that values action orientation, a customer-first mindset, effective teamwork, and a drive to excel.
