This is a remote position.
As a Backend Engineer, you will play a critical role in building and maintaining the server-side logic, databases, and APIs that power our web and mobile platforms. Your primary focus will be on ensuring seamless data exchange, optimal performance, and robust scalability.
You will go beyond standard application development to handle infrastructure optimization and automation scripts, working closely with frontend developers, DevOps, and product stakeholders to deliver secure and reliable backend solutions. You will leverage modern technologies such as Node.js, Python, PostgreSQL, MongoDB, and Kafka to architect and deliver scalable, event-driven systems.
