FORMAL METHODS ENGINEER

Founded in 2022 to empower manufacturers to choose the content of their CPUs, Keysom has developed highly modular processor architectures based on the RISC-V ISA.

The wide range of configurations allows Keysom to offer the world’s largest catalog of processor architectures, with over 10 million possibilities today.

Our tool, CoreXplorer—the first no-code architectural exploration tool—enables users to select the best CPU for their application in just a few minutes.

MISSION

In the context of fault elimination in hardware systems, Keysom is seeking a formal methods engineer. Your role will be to apply correct-by-construction design methods—typically reserved for the computer science field in academia—to hardware design in an industrial context.

The idea is to guide the description of hardware systems toward abstract models, on which specifications are verified, and then, through successive refinements, arrive at the concrete model that can be translated into an implementation.

Formal verification methods are applied to the design of processor architectures based on the RISC-V instruction set.

Main Responsibilities

• Construct, using a proof assistant, semantic rules, and descriptions of the system and its specification, proofs of functional correctness.
• Establish and demonstrate simulation relationships between abstract and concrete models that guarantee semantic preservation.
• Propose methods for industrializing state-of-the-art design paradigms to minimize the proof effort.
• Conduct academic monitoring: stay informed of state-of-the-art advances in methods for verifying the functional correctness of hardware systems and semantic preservation.

YOUR PROFILE

Education and Experience

You hold a Ph.D. in computer science and have research experience in automata theory and/or language theory and/or correct-by-construction design.

An interest in hardware architecture design and the RISC-V instruction set is appreciated.

Skills

• Proficiency in a proof assistant such as Rocq or Lean.
• Proficiency in an interpreted programming language (Python/Perl/Ruby/Tcl).
• Understanding of hardware description languages such as VHDL or Verilog.
• Intuitionistic natural deduction.
• Writing programs using the functional programming paradigm.
• Understanding of hardware design constraints in the industrial sector.
• Excellent spoken and written English.

DETAILS

• Compensation: based on qualifications

WHAT WE OFFER

• 100% coverage of employee and children’s health insurance.
• Opportunity to combine this role with university teaching.
