Join OLX and see how far you can go.
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 Required:
1). Core Tracking and Analytics Expertise:
- Experience with Tracking Systems: Proficiency with tools like Google Analytics (GA4), Adobe Analytics, or Segment. Focus on GA4 is a plus, especially for auditing and improving its use
- Event-Based Tracking Frameworks: Solid understanding of event-based tracking frameworks (e.g., how to implement and monitor user behavior events, troubleshoot issues, and audit event data)
- User Behavior Analysis: Experience in defining and interpreting metrics related to user flows, product usage, and customer journeys to improve product insights and tracking accuracy
2). Backend and Frontend Proficiency:
- Backend Experience: Strong foundation in a JVM-based language (Java, Scala) or Python for implementing server-side tracking
-Frontend Proficiency: Experience with React or other modern front-end frameworks for implementing tracking on web applications. Familiarity with Next.js is a plus but not required
3). Data Infrastructure and Processing:
- Cloud Data Management: Working knowledge of the AWS ecosystem with a focus on services relevant to data and tracking (e.g., S3, Lambda, Kinesis)
- Data Pipeline Experience (nice to have): Understanding of streaming data processing (e.g., Kafka or Kinesis), which would be helpful in real-time tracking scenarios
4). Data Quality and Governance:
- Data Quality & Governance: Experience in data governance for tracking compliance with GDPR and ensuring data integrity in analytics
- Metrics Definition and Auditing: Ability to define key metrics, audit data accuracy, and develop dashboards for tracking data quality and product analytics.
5). Collaboration and Change Management:
- Implementation Support: Proven experience working with cross-functional teams (product, engineering, analytics) to coordinate tracking implementations and resolve technical dependencies
- Tracking Documentation: Ability to create clear documentation for the tracking framework to guide product teams in implementation and adoption
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
