Own project delivery quality and help maintain operational clarity across projects
 

🎯Requirements

- Strong senior-level hands-on experience with Meta Ads
(TikTok, Pinterest, Google, Snapchat Ads is a plus)

- Experience communicating directly with clients

- Ability to prioritize, structure work, and coordinate execution with other team members
 

🎯We are specifically looking for someone with a strong senior media buyer background who feels ready to step into a Team Lead role and take ownership over strategy, delivery, and project coordination

You do not need experience managing large teams

👉 However, you should feel comfortable:
- leading buyers strategically,
- conducting syncs and reviews,
- setting priorities,
- reviewing and helping create game plans,
- and being accountable for project direction and delivery quality

- Strong understanding of attribution, tracking, custom conversions, and cross-platform analytics

Project Description

We help marketers connect the digital and physical world. We provide data-driven solutions to enhance marketing campaigns by leveraging location and audience data to reveal consumer behavior and enable more precise targeting and measurement. We work on high-end / high-performance / high-throughput systems for in-time analysis of data for autonomous driving and other big data applications e.g. for E-commerce.

Job Responsibilities

Work in a self-organised agile team with a high level of autonomy, and you will actively shape your team's culture.

Design, build, and standardise privacy-first big data architectures, large-scale data pipelines, and advanced analytics solutions in AWS.

Develop complex integrations with third-party partners, transferring terabytes of data.

Align with other Data experts on data (analytics) engineering best practices and standards, and introduce those standards and data engineering expertise to the team in order to enhance existing data pipelines and build new ones.

Successfully partner up with the Product team to constantly develop further and improve our platform features.

Requirements:

• 4+ years in a Data Engineering or similar high-scale role.
• Expert-level Python skills. Familiarity with Java or Scala is a major plus.
• Proven hands-on experience building scalable solutions directly within AWS.
• Deep proficiency in high-throughput architectures using Kafka, Spark, Hadoop, MongoDB, AWS Batch, AWS Glue, Athena, Airflow, and dbt.
• Exceptional SQL and data transformation skills, with an eye for optimizing NoSQL and SQL databases.
• Ability to simplify complex technical concepts and a passion for mentoring junior engineers in a collaborative environment.
