A system of high availability (+ 99.9%) and with high throughput, written in Java;
Create metrics and monitors for platform monitoring;

Must-haves to shine in this role:

Ability to solve problems through the evolution of existing software products;

A great ability to learn new practices, technologies, programming languages and absorbing engineering culture;
Full knowledge of SQL and relational databases;
Understanding of design patterns and object-oriented principles;

What would we love to see?

Passion for software, you go to sleep and wake up thinking about how to make that part of the system more elegant or efficient;
Software development expertise in any complementary area to our core business, such as data warehouses, specialized development platforms, infrastructure automation, services provisioning, real-time systems, fault-tolerant systems and mission-critical systems;
Experience with deploying to and monitoring a cloud infrastructure, especially AWS;
Experience with computer networks, latency, package loss, routing optimization, monitoring, and problem-solving;
