A Staff Engineer position is available in the EU Data Engineering team, Data Platform. Reporting to the Head of Data Engineering, you will be able to lead shaping the future of our Data Stack.
You will work alongside a Principal Data Engineer, two Lead Software Engineers (Frontend and Backend), a Data Engineering Manager (with a team of six Data Engineers) and a Software Engineering Manager (with a team of seven Software Engineers).
As a Staff Engineer, you will be expected to take ownership of key components of our Data Stack and drive technical decisions aligned with our overall data platform architecture. Although not owning the architecture vision of our Data Stack, you will have the opportunity to influence its direction by partnering with other Leads and the Principal Data Engineer.
You will serve as a role model to more junior team members, perform peer code reviews, help them grow their skills, and act as a technical guide. You will help the team execute and set technical standards.
Responsibilities:
- Gain a comprehensive understanding of the architecture of our web platforms across different CUs (OLX, Real Estate, Motors), and identify pain points where tracking is inconsistent or challenging. Achieve this by interviewing engineering managers and individual contributors.
- Develop an implementation framework that aligns with the technical realities of all CUs and addresses identified pain points to enhance the accuracy of user behavior measurement. You will have support from the Chief Data Officer and Engineering Managers. Existing pain points have been outlined.
- Design the framework to automatically push metadata from the code to our central metadata repository, reducing manual work on event and property creation.
- Collaborate with product analytics and data service teams to coordinate necessary implementation changes to improve tracking accuracy, such as modifying event types, fixing implementation errors, and ensuring seamless information transmission across codebases.
- Audit the implementation of GA4 and provide guidance on maximizing its potential. Currently, GA4 is underutilized (20-30% of its capacity) and may not be correctly implemented according to GA recommendations. Ensure proper implementation in our internal tracking solution and follow best practices for GA4.
Skills we're looking for:
- AWS data ecosystem
- Experience with tracking systems (e.g., Google Analytics, GA4, Adobe Analytics, or Segment) and user behavior analysis
- Strong understanding of event-based tracking frameworks and how to implement, monitor, and audit them
- Experience with data governance and ensuring tracking compliance with GDPR and other data privacy regulations
- Experience defining and auditing metrics related to user behavior, product usage, and customer journeys
- Data governance applied to cloud/enterprise platforms
- Streaming processing (e.g., Kafka, Kinesis, Storm, Flink, Spark Streaming)
- Expertise in SQL and Python
- JVM-based languages, such as Scala and Java
- Knowledge of S3, SQS, EC2 Auto Scaling, Kinesis, Lambda, EMR, Hive, and Glue
- Knowledge of CI/CD, Docker, and K8s
- Infrastructure-as-code tools (e.g., Terraform, CloudFormation)
- Professional experience working with React or any other modern front-end frameworks. Next.js is a plus
- Experience with defining metrics, tracking data quality, and developing dashboards/reports for product analytics
What we will give you:
- Competitive salary depending on seniority
- Annual bonus up to 20% of your annual salary
- Work with an international team of top engineers learning from one another
- Equipment you might need and a company mobile phone
- A budget for education, training and conferences
