Backend Engineer • Senior

Who you are

You have 5+ years of backend engineering experience building scalable production systems — you've owned services from design through deployment and have faced the challenges of debugging complex distributed systems. Your expertise in Java and Spring is deep — you've shipped high-throughput APIs that handle millions of requests and have strong opinions on service architecture, dependency injection, and testing strategies. You are familiar with cloud services, particularly AWS, and understand how to leverage them to optimize performance and reliability. You thrive in environments that require a 'Founder's Mentality' — taking ownership of your work and driving projects forward with minimal oversight. You are a problem-solver at heart, eager to tackle complex challenges and innovate in the video streaming space. You enjoy collaborating with cross-functional teams, including product and design, to enhance user experiences and deliver exceptional storytelling.
