Project scope

The team is responsible for developing and maintaining one of the key data processing platforms. Currently, the focus is mainly on DevOps initiatives and R&D work, which is why we’re looking for someone to take ownership of the Data Quality area and have a real impact on the quality of data delivered to clients. Your main responsibility will be to identify, analyse, and eliminate data quality issues, as well as build solutions to reduce their recurrence in the future.

This is a role with a high degree of autonomy and real impact; you’ll work alongside an experienced team of engineers, while also having the space to propose your own improvements and shape the overall approach to Data Quality. The project presents interesting technical challenges. Any mechanisms for improving data quality must be designed so as not to affect the performance of the production environment. Instead of “inline” solutions, offline approaches are used, allowing issues to be analysed and fixed without impacting data processing time. We’re looking for someone who will help not only reduce the existing backlog of data quality issues, but also develop a more proactive approach to detecting and preventing problems. This is an interesting project for someone who enjoys working at the intersection of data engineering, analytics, and automation and wants to make a real impact on the stability and quality of a large data ecosystem.

Team

Around the product, there are a couple of subteams; you will be the third teammate of the Data Quality team that focuses on improving the quality of the data portfolio.

Expected Capabilities & Expertise:

– Data analyst instincts + software engineer’s hands. ~70% of the job is finding a cohort in BigQuery, working out why the data is wrong, and fixing it at scale. Strong SQL and genuine curiosity about data are non-negotiable.

– JVM backend (Kotlin/Java, Spring Boot). Must be able to build their own remediation tooling and checks, not just run queries. Beam/Dataflow, Kafka, Snowflake, Bigtable are a plus, not a must.

– Data quality/observability mindset. Has built monitors, data tests, or anomaly detection. Understands the difference between firefighting and building prevention and wants the second.

– Ownership and autonomy. The backlog is unassigned and partly undefined. They must take a vague ticket, scope it themselves, deliver, and propose what’s next. Fluent English, direct work with the US team, remote.

– Comfortable with legacy and ambiguity. A live, latency-sensitive system where fixes run offline, and validation is statistical, not a green test. No greenfield here.
