But we’re not just another auditor. We’re a full‑stack security assurance platform, combining best‑in‑class formal verification tools with expert advisory services, delivered on time and with zero compromise. Whether you’re launching a new protocol, upgrading core infrastructure, or securing a DeFi primitive, Certora doesn’t just look for vulnerabilities. We help you prove correctness, accelerate your development speed, and embed safety into your design from day one.

With Certora, you get:

Proven, scalable tooling for checking real deployed code
A deep partnership model with on‑demand support
Fast, responsive execution that helps you go‑to‑market faster

For us, security isn’t a checklist, it’s a continuous process. Certora is the most comprehensive and trusted platform to ensure your platform is protected, even under adversarial conditions. From testnet to mainnet, we’re with you.

About the role

We are looking for a full‑time Formal Verification Researcher to lead the adoption of formal methods of financial systems using a unique formal verification product called the Certora Prover. You will use the Prover to prove the mathematical properties of complex financial systems such as Aave and Lido, which are implemented using computer programs called smart contracts and improve the Certora Prover technology. The role requires comprehending complex code and finding modular ways to prove the correctness of the systems. In particular, we harness SMT solvers to find critical bugs in financial systems, thus requiring a deep understanding of the technology’s advantages and limitations and developing the correct verification methodology. You will also assist the product team by proposing enhancements to the Certora Prover to enable and promote wider‑scale usage and development of additional products.

Relevant skills

Academic graduate degree in Math, Physics, or Computer Science from an excellent research university. Outstanding candidates with an undergraduate degree will also be considered.
Passion for applying cutting‑edge technology to financial systems.
At least three years of software development experience.
Background in vulnerability research, especially with high‑level code (an advantage).
DeFi and Fintech understanding (an advantage).
Formal verification background, especially with tools such as Dafny, Lean4, Coq, and Isabelle (an advantage).
Outstanding junior candidates will also be considered.

Responsibilities

As a Formal Verification Researcher at Certora, you will:

Lead formal verification projects of complex DeFi protocols using the Certora Prover.
Rapidly understand new customer codebases and financial systems (e.g., lending protocols, staking systems).
Identify the most critical safety and security properties of smart contracts and formally specify them according to the implementation.
Apply compositional reasoning to prove properties and relevant assumptions using the Certora Prover.
Detect vulnerabilities and critical bugs through SMT‑based verification methodologies.
Produce high‑quality security reports that document formal verification results, identified issues, and proof outcomes.
Communicate findings clearly to clients, including both technical audiences and non‑specialists.
Collaborate with client teams to review proposed security fixes and verify their correctness.
Work closely with the R&D team to suggest improvements to the Certora Prover and contribute to broader product development.
Stay flexible and adaptive in project‑based work: handling evolving requirements, changing codebases, and shifting priorities.
