Security Engineer, Smart Contracts; Security

Position: Staff Security Engineer, Smart Contracts (Security) Location: Germany Location Remote Employment Type Full time Location Type Remote Department Engineering 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. Eigen Cloud changes this by making any digital service verifiable. Built on our Eigen Layer protocol, which has attracted billions in economic security, Eigen Cloud 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. The Role As a Smart Contract Security Engineer, you won’t just audit code—you’ll shape the security model for billions of dollars of restaked ETH and safeguard the trust of an entire ecosystem. You’ll work at the intersection of cutting-edge research, high-stakes engineering, and adversarial thinking, building defenses for a protocol that is redefining how crypto infrastructure is shared and secured. This is a chance to tackle some of the hardest problems in blockchain security, collaborate with world-class researchers and engineers and if you thrive on high impact, high responsibility, and pushing the boundaries of what secure decentralized systems can be, Eigen Layer is where you’ll want to be. This is a full-time position that is fully remote or located with the largely Seattle-based team.

What You Will Do

• Lead design and security reviews of complex staking, slashing, Eigen Pods and reward distribution contracts.
• Build tooling, fuzzers, and formal verification pipelines to identify vulnerabilities before attackers do.
• Collaborate directly with protocol researchers and core engineers to harden new features from inception.
• Read, interpret, and refine formal verification specifications, making changes as needed to ensure they reflect protocol intent and capture critical security properties.
• You will work closely with the product and leadership teams to set the on-chain strategy and roadmaps. This is a unique opportunity to build an entirely new paradigm of permissionless innovation, and create outsized impact on Eigen Layer, and the Ethereum community.

What You Will Bring

• Deep understanding of blockchain fundamentals, common vulnerabilities, and the EVM
• Experience with developer tools for smart contract application developers (Hardhat, Foundry)
• Passion for collaborating with other developers, security auditors, and stakeholders to ensure the quality and security of smart contracts
• Strong testing skills and experience with testing frameworks for smart contracts
• Experience with production deployments of non-trivial protocols, and associated security audits
• Ability to collaborate with cross-functional and geographically remote teams, partners, and community members
