Collaborate with SDEs, security engineers, and partner teams to translate verified implementations into production-grade, FIPS-validated software.
Grow your expertise through publications, open-source contributions, and engagement with the broader formal-methods and cryptographic research communities.
A day in the life
You take a cryptographic algorithm that needs to be provably correct. Working with a senior scientist or an ARG partner, you write the formal specification of its behavior, develop the proof in an interactive theorem prover, and iterate until the machine checks it end to end. Some days you are debugging a proof obligation that does not discharge; other days you are reading a paper on a new verification technique or helping refine an algorithm implementation so it is both fast and amenable to proof. Your proofs back code that is validated for FIPS and deployed across AWS, so you operate at an assurance bar most scientists never encounter this early in their career.
About the team
ACL owns AWS-LC (Amazon's FIPS-validated libcrypto), the Amazon Corretto Crypto Provider (ACCP), and managed third-party cryptographic libraries, the cryptographic foundation under nearly every AWS service and a growing set of external open-source projects. Applied Scientists on the team own algorithm-level and assembly performance work and partner deeply with Amazon's Automated Reasoning Group on formal verification. The team has senior scientists who actively mentor and collaborate, so an early-career scientist gets both research depth and production-scale reach from day one.
PhD or equivalent research experience
Experience in any of the following areas: mathematical logic, formal verification, satisfiability solving (eg SAT/SMT), mechanical theorem proving, model checking, or program analysis
Hands-on experience with an interactive theorem prover (HOL Light, Isabelle/HOL, Lean, Coq, or Verus)
Experience specifying or verifying low-level software (machine code, C, or assembly)
Familiarity with cryptographic primitives and their implementations
Low-level or systems programming experience in C, Rust, or assembly
Familiarity with post-quantum cryptography (lattice-based, code-based, or hash-based schemes)
