Tech Lead, Filecoin Saturn

Apr 24, 2023

Job Description

Protocol Labs drives breakthroughs in computing to push humanity forward. Protocol Labs is a product-development lab, but behind the protocols and tools we build, behind the research and implementations, are passionate people, teammates and community members. Most teams in the Protocol Labs Network are fully distributed and work remotely around the world. Engineers, researchers, and operators work in the open to improve the internet — humanity's most important technology — as we explore new advances at the intersection of many exciting fields (crypto, networks, distributed systems) and cultures (startups, research, open source, distributed work).


Filecoin, a decentralized storage network to store humanity's most valuable information, is one of the most promising projects of Web3. In the two years since its launch, over 18 exabytes of storage have been pledged to the Filecoin network, which is proven and verified by node operators every single day. As we look forward, many challenges remain to be solved such as continuing to scale the network, allowing user programmability through the addition of a Virtual Machine, and implementing cutting-edge ideas coming from the latest in cryptographic research.

Filecoin Saturn

One such challenge is the reliable, performant, and economic retrieval of content from Filecoin. Filecoin Saturn is a decentralized content delivery network (CDN) for Filecoin. We're seeking a tech lead engineer to join the Filecoin Saturn team.

For this role, we particularly value experience independently designing and implementing significant components of complex systems, and the execution focus and discipline to carry projects to completion. Experience leading strong open source communities and/or contributing to other blockchain-like projects will be very highly regarded, as well as experience working on low-latency engineering projects.
