Tempo is a purpose-built, EVM-compatible layer 1 blockchain designed for payments. Incubated by Stripe and Paradigm and built with input from fintechs and Fortune 500s, Tempo supports major stablecoins to enable high-throughput (100k+ TPS), low-cost, sub-second finality transactions with predictable near-zero fees, privacy controls, compliance hooks, and payment-specific features like memo fields and batch transfers. It targets real-world payment flows — remittances, global payouts, embedded finance, microtransactions, and tokenized deposits — while offering stablecoin interoperability and a dedicated payments lane for reliable, scalable global payments.

📋 Description

• Proactively hunt for vulnerabilities in the Tempo protocol, consensus engine, and bridge architecture, treating our mainnet like a continuous CTF challenge. • Design and implement security tooling and automation in liaison with the Foundry team to catch logic errors and edge cases. • Partner with engineering teams to review critical architecture across our codebase. • Analyze incentives and game-theoretic risks within the protocol, such as MEV and staking dynamics, to prevent economic exploits.

🎯 Requirements

• Fluency in reading and writing production-level code in systems languages, with a strong preference for Rust. • Deep expertise in EVM internals, including intimate knowledge of opcodes, storage slots, gas metering, and precompiles. • Proven track record of offensive security, such as high rankings in CTFs (e.g., Paradigm CTF), high-severity bug bounty submissions, or published research. • Experience building custom security automation or tooling rather than relying solely on off-the-shelf scanners. • Bleeding-edge knowledge of the latest blockchain security research, including recent hacks and how these could have been mitigated.

🏖️ Benefits

• Health insurance • 401(k) matching • Flexible work hours • Paid time off • Remote work options
