Sign up with Clera and we'll reach out the moment a role actually fits you — no more spraying applications into the void.
Design and develop highly scalable, fault-tolerant solutions as part of the core engineering team. Responsibilities include enhancing the automation suite and analyzing complex usage scenarios to maintain product quality.
Requires 3-5 years of C++ development experience with strong knowledge of system and network programming across Windows and Unix. Proficiency in multithreading, algorithms, and software engineering best practices is essential.
LucidLink is the file streaming platform for large-file workflows. We give teams and tools instant access to data in the cloud, so work starts right away, anywhere. No downloads, no syncing, no VPNs. What began as a faster way to open huge media files is now a platform spanning streaming from existing storage, on-site acceleration, web and mobile access, and a developer layer that connects agents to the filespace, all with zero-knowledge security and enterprise governance built in. More than 4,000 companies — including Adobe, Spotify, Warner Bros, and Paramount — and 100,000 users in over 150 countries stream more than 100 petabytes with LucidLink, and the Television Academy has recognized us with an Engineering, Science & Technology Emmy Award. Founded in 2016 by storage industry veterans, we are headquartered in San Francisco with an engineering office in Sofia, Bulgaria, and remote employees across North America, Europe and Australia.
Tackle big challenges: You’ll have the chance to solve complex, high-stakes problems that redefine how teams collaborate globally.
