Senior Data Collection Engineer

About the role

We are looking for a Senior Data Collection Engineer to help design, build and operate Fever’s tracking and measurement infrastructure at scale.

This role sits at the intersection of engineering, data architecture and product, with a strong focus on server-side tracking, first-party data collection and DWH-first measurement systems. You will not be implementing ad-hoc pixels for the sake of it — your work will shape how data is reliably collected, governed and activated across the entire company and its partners.

You’ll be working on Dataverse, Fever’s internal tracking layer, used across web, app, marketplace, whitelabels and multiple companies within the group.

What you will do

• Design and evolve server-side tracking architectures (GTM Server-Side, middleware, APIs, event pipelines)
• Implement and maintain first-party data collection systems across web and app
• Own complex JavaScript-based tracking logic, both client-side and server-side
• Define and enforce tracking standards (events, schemas, identifiers, consent-aware logic)
• Ensure tracking data flows reliably into the Data Warehouse (Snowflake) as the source of truth
• Build scalable solutions to support marketing, experimentation, SEO, product and partners
• Collaborate with Growth, Product, Data Science and Engineering teams on measurement needs
• Help evaluate trade-offs between vendors (GA4, Mixpanel, Meta, etc.) and internal systems
• Participate in incident analysis, performance tuning and load testing of tracking infrastructure
• Contribute to internal documentation and external-facing capability documents for partners

What you bring

• Strong experience with JavaScript (ES6+), including advanced concepts and browser internals
• Hands-on experience with server-side tracking (GTM Server-Side, custom endpoints, or similar)
• Solid understanding of web tracking fundamentals: cookies, localStorage, sessions, identity, consent, attribution
• Experience working with event-based data models and structured schemas
• Familiarity with cloud environments (GCP preferred, AWS acceptable)
• Experience integrating data into a Data Warehouse (Snowflake, BigQuery, etc.)
• Ability to reason about data quality, reliability and scalability, not just implementation
• Comfortable working autonomously in a cross-functional, fast-moving environment

Nice to have

• Experience with mobile tracking (iOS / Android concepts, even if not native development)
• Knowledge of privacy and consent frameworks (GDPR, CMPs, Consent Mode)
• Experience with middleware or streaming systems
• Background in analytics engineering or data engineering

Must-have skills

• 5+ years of hands-on experience in data collection, tracking implementation, or measurement infrastructure roles
• Proven track record designing and maintaining scalable tracking systems in production environments
• Strong knowledge of best practices in event tracking, data quality, and testing methodologies
• Experience designing scalable data collection systems and event-driven architectures
• Ability to deliver code from development to production while ensuring high-quality engineering solutions
• High autonomy and a proactive mindset for identifying and solving problems with a bias for action
• Exceptional communication skills and ability to thrive in collaborative, cross-functional environments
• Growth mindset, adaptability to change, and commitment to continuous improvement
• Empathetic, inclusive, and curious attitude with a passion for making a positive impact through technology
• Advanced English proficiency (written and spoken)

Your journey at Fever

On your first month:

• You will get familiar with Fever's tech stack, data infrastructure and Dataverse architecture
• You will understand Fever's business model, data strategy and how tracking supports growth

After 3 months:

• You will be able to come up with solutions to complex tracking challenges, from architecture design to implementation
• You will have shipped production-grade tracking solutions handling high traffic volumes while maintaining data quality
• You will participate in hackdays or hackathons with other teams, and know most people from engineering and data teams

On your 6th month:

• You will have ownership over critical parts of the tracking infrastructure, analyzing usage patterns and evolving the system
• You will own parts of the technical roadmap for data collection and, with team support, bring that roadmap to reality
• You will enable the data architecture to support Fever's growth and new product initiatives
• You will mentor other engineers through code reviews, architecture design sessions and pair programming
• You will participate in team buildings organized for your team or the whole engineering organization
• You will have led ambitious initiatives to improve data reliability, governance and activation
