In the Data Infrastructure team, we collect several billion events per day and query hundreds of terabytes in real time.

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.

Your daily work will consist of:

- Leading large scale projects that involves 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

- 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.

We are looking for engineers with a solid software engineering foundation, who enjoy working close to the data infrastructure layer and solving complex distributed systems challenges at scale.

You will:

Design and build highly scalable backend systems processing petabytes of data with strict latency and performance constraints

Challenge the status quo by redesigning and unifying inherited data pipelines into a streamlined, scalable architecture

Work on large-scale, performance-critical systems, handling high data volumes with strong constraints on CPU, memory, throughput, and latency

Reason about concurrency, data consistency, fault tolerance, and backpressure in distributed systems

Develop efficient data formats and exchange mechanisms that optimize functionality while minimizing cost and maximizing performance

Contribute to the continuous evolution of the core data pipeline, supporting growing data volumes and new functional requirements

Collaborate closely with cross-functional teams to ensure data solutions align with the company’s strategic goals

Whether you are a mid-level or senior engineer (6+ years of experience), you have a strong software engineering foundation and a good grasp of core computer science concepts.

You have worked with dynamic complex systems in a rich ecosystem with lots of integrations.

You have hands-on experience tackling large-scale data challenges, focusing on scalability, low-latency processing, and fault-tolerant system design.

You have experience with cloud providers such as AWS and Azure, with a comfort in writing infrastructure as code.

You have strong communication skills, with the ability to collaborate effectively in a team environment on-site but also in async with people around the world.

You have the ability to thrive in a flat team structure, actively contributing to solving technical challenges alongside peers.

You are proactive, full of ideas, with a critical yet constructive attitude and a positive approach to bringing thoughtful input.
