AppSec Engineer

Eigen Labs is building the infrastructure for a more trustworthy internet.

Today's digital world runs on trust-me promises: "Trust that this AI model is giving you unbiased results." "Trust that this platform isn't manipulating your feed." "Trust that this service will honor its commitments." These trust assumptions create massive friction and limit what's possible online.

EigenCloud changes this by making any digital service verifiable. Built on our EigenLayer protocol, which has attracted billions in economic security, EigenCloud lets developers build applications with mathematical trust guarantees instead of pinky promises.

For developers, this means the best of both worlds: Use familiar cloud tools and programming environments while gaining blockchain-level verifiability. No need to rewrite your application in specialized blockchain languages or accept the limitations of smart contract environments.

For the world, this unlocks transformative applications:

• AI systems with economic accountability for their outputs

• Social platforms with verifiable, manipulation-resistant algorithms

• Prediction markets that can resolve on any real-world event

• Financial services with cryptographic transparency

• Any application where trust and correctness matter

We're moving beyond crypto's current focus on digital money to make all digital interactions more trustworthy. With the fastest-growing developer ecosystem in crypto and backing from top-tier investors, we're at the inflection point where verifiable computing goes mainstream.

Ready to build the trust layer for the internet? We're looking for builders who want to solve hard problems and create technology that makes the digital world fundamentally more reliable.
