Security Engineer

As a Security Engineer at Tempo, you will build and lead a full-time internal Red Team to continuously stress-test the protocol's infrastructure. You will write Rust fuzzers, simulate economic attacks on the testnet, and dissect the EVM to find edge cases in the execution client. This role is for someone who understands that the best way to secure a protocol is to try to break it continuously.

What you'll do

• Proactively hunt for vulnerabilities in the Tempo protocol, consensus engine, and bridge architecture, treating 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 the codebase
• Analyze incentives and game-theoretic risks within the protocol, such as MEV and staking dynamics, to prevent economic exploits

What you bring

• 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
• A proven track record of offensive security, such as high rankings in CTFs (for example, 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
• High motor and razor-sharp thinking with precise command of language
• Concise, evidence-based communication and excellent organizational and logistical skills
• Intense curiosity, open-mindedness, scrappiness, and a growth mindset
