We’re currently hiring for two positions (mid-level and senior) to join our team of passionate and talented engineers, and help design and build the next generation of our data architecture, powering real-time insights at massive scale.

• Leading large scale projects that involve complex systems with leading edge technologies.
• Thinking of smart data formats and ways of exchanging it to serve the functionalities of the product, while minimizing the cost and increasing performance.
• Increase the team's expertise by bringing in new ideas and mentoring other developers using (but not limited to) some open source technologies such as Scala, Go, Kafka, and Click House.

• You are looking for a variety of cool projects, which will redefine analytics and UX with big data.
• You would like to challenge yourself developing distributed infrastructure with a real time and data-intensive environment.
• You are looking for an environment where you'll have the occasion to be a technical reference on your areas of expertise, all while taking responsibilities on strategical corporate axes and collaborating with your peers.

• Design efficient, data‑intensive backend services to collect, process, and store petabytes of data, with a strong focus on performance, scalability, and system behavior under load.
• Challenge the status quo by redesigning and unifying multiple inherited data pipelines, driving the transition to a streamlined, harmonized data architecture.
• Investigate, debug, and optimize system behavior across CPU, memory, I/O, and concurrency dimensions as data volumes grow.
• Lead large‑scale projects that involve complex systems and cutting‑edge technologies, driving impactful changes across the organization.
• Develop innovative data formats and exchange mechanisms that optimize functionality while minimizing costs and maximizing performance.
• Share knowledge and increase the team's expertise by introducing new ideas and mentoring fellow engineers.
