About Tempo
Tempo is a Layer 1 blockchain designed specifically for stablecoin payments and real-world financial transactions. Built using the Reth SDK, Tempo features dedicated payment lanes that guarantee blockspace for payment transactions regardless of network congestion, stablecoin-native gas fees allowing users to pay transaction costs in any USD-denominated stablecoin, and Byzantine fault-tolerant consensus achieving approximately 0.5-second finality. The blockchain includes a native decentralized exchange optimized for stablecoins, structured memo fields for reconciliation against enterprise systems, and protocol-level compliance features through the TIP-403 Policy Registry. Tempo was incubated by Stripe and Paradigm, with design input from global partners including Anthropic, Deutsche Bank, OpenAI, Shopify, Visa, and Standard Chartered. The blockchain launched its public testnet in December 2025, operating with an initial set of validators before transitioning to a permissionless validator model. Tempo raised $500 million in Series A funding at a $5 billion valuation in October 2025, led by Thrive Capital and Greenoaks with participation from Sequoia Capital, Ribbit Capital, and SV Angel.

About the Role
You will establish application and infrastructure security from the ground up. You will build security tooling, address vulnerabilities, lead incident response, conduct secure design reviews, improve supply-chain security, and develop practical security practices for building, deploying, monitoring, and securing systems.
Requirements
- 5–8 years of hands-on product or application security engineering experience
- Experience building security practices in a 100–500 person company or a similar environment with limited security infrastructure
- Hands-on coding ability for building security tooling, automation, and detection
- Deep incident-response experience including ownership of high-severity situations end-to-end
- Strong infrastructure security knowledge covering hosting environments, network security, monitoring, and system integrations
- Application security fundamentals including threat modeling, secure code review, vulnerability management, and supply-chain security
- Ability to communicate technical security decisions to engineers with depth and specificity
Responsibilities
- Build and deploy security tooling across endpoint management, supply-chain security, infrastructure, and application layers
- Identify and remediate security gaps across production systems and development pipelines
- Lead incident response through triage, containment, remediation, and post-mortems
- Partner with engineering on secure design reviews and operational security decisions
- Establish repeatable security practices for building, deploying, monitoring, and securing systems
- Improve supply-chain security across dependencies, build systems, and deployment artifacts
- Scale application-security coverage as infrastructure and product surfaces grow
- Operate autonomously and build necessary security capabilities
