About the Role

  • Own security across protocol-layer components (L2, bridge, custody)
  • Act as the final gatekeeper before code hits main
  • Lead threat modeling, design reviews, and mitigation planning
  • Write critical patches and drive hardening when bandwidth is limited
  • Maintain security CI tooling: sig-verification, SAST, fuzzing, secrets scanning
  • Review 100% of protocol-relevant PRs and enforce automated checks
  • Run secure coding workshops and pair-program during critical sprints
  • Interface with auditors and bounty researchers to scope, triage, and fix issues
  • Authority to block merges or deploys on security grounds
  • Direct commit access for emergency fixes

What We're Looking For in You

  • 5+ years in security engineering with hands-on software experience
  • Strong background in Rust, Go, or Solidity
  • Deep knowledge of threat modeling and real-world exploit paths
  • Experience owning or maintaining CI-based security automation
  • Comfortable leading security without direct org ownership
  • Bonus: protocol-level blockchain experience, audits, bounties, or custody systems

Alpen Labs is a technology company at the forefront of advancing Bitcoin's capabilities through the integration of zero-knowledge (ZK) cryptography. Founded in 2022 by a team of MIT alumni, the firm is dedicated to building infrastructure that enhances Bitcoin's scalability, programmability, and privacy without compromising its core principles of decentralization and security. The company's mission is to establish universal rails for money by creating a robust and efficient ecosystem on top of the world's most trusted digital asset. By developing a modular rollup layer on Bitcoin, Alpen Labs aims to anchor applications to Bitcoin's secure foundation, thereby unlocking its vast potential for a new wave of decentralized finance (DeFi) and other on-chain applications. This initiative is designed to tap into Bitcoin's native assets and foster a more inclusive and accessible global financial system.

The company's vision encompasses a programmable, scalable Layer 2 ecosystem on Bitcoin, which it believes is the ideal environment for the future of on-chain finance. This includes a wide range of applications from payments and lending to custody, stablecoins, and other yet-to-be-imagined use cases. Alpen Labs is actively developing 'Strata,' a Bitcoin ZK Rollup, with a mainnet launch planned for 2025. This platform is intended to be open, introducing easy and scalable self-custody while facilitating broader use of Bitcoin. The company has successfully emerged from stealth with significant funding from prominent investors, underscoring the industry's confidence in its approach. The team, composed of experienced cryptographers, engineers, and researchers from leading technology firms, is focused on solving complex engineering challenges to redefine financial sovereignty and expand individual agency in the digital economy. Through its innovative work, Alpen Labs is paving the way for a more dynamic, efficient, and secure financial future built on the Bitcoin network.
