Sr. Formal Verification Engineer, Amazon Leo

Job description

Amazon's Leo Silicon Team is building next-generation modem SoCs for broadband

communication, a constellation of low Earth orbit satellites designed to deliver fast, affordable broadband to unserved and underserved communities around the world. Our Design Verification team is seeking a highly skilled and motivated Senior Formal Verification Engineer to drive formal verification efforts across our complex modem SoC designs.

In this role, you will apply rigorous mathematical methods to prove design correctness and

uncover corner-case bugs that escape simulation-based verification. You will serve as a subject matter expert in formal verification methodologies, mentor engineers across the team, and collaborate closely with RTL designers, simulation-based DV engineers, emulation engineers, and architects to shift verification left and improve overall silicon quality. This is a high-impact role on a team that is scaling verification capabilities with each successive tape-

out and actively integrating AI-centric verification methodologies.

Export Control Requirement

Due to applicable export control laws and regulations, candidates must be a U.S. citizen or national, U.S. permanent resident (i.e., current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.

Key job responsibilities

• Develop and execute formal verification strategies using JasperGold and/or Questa

Formal for property checking (FPV), connectivity checking (CC), register verification,

and sequential equivalence checking (SEQ)

• Write, review, and debug SystemVerilog Assertions (SVA) — including assumptions,

assertions, and cover properties — to verify complex modem SoC design behaviors

across NOC, interconnect, modem IPs and control logic

• Drive convergence on formal proofs by applying abstraction techniques, complexity

reduction strategies, and assume-guarantee reasoning

• Collaborate with RTL designers, architects, and simulation-based DV engineers to

define verification plans that incorporate formal methods alongside UVM-based

simulation and emulation approaches

• Champion a "formal-first" verification strategy by identifying and pursuing

opportunities to apply formal verification to new design blocks — building on our

established formal verification checklist deployed across SoC and NoC partitions

• Develop reusable formal verification infrastructure, including constraint libraries,

parameterized property templates, and automated regression flows integrated into our

CI/CD verification pipeline

• Contribute to coverage closure strategies by leveraging formal coverage analysis to

complement simulation-driven functional coverage

• Mentor and guide DV engineers in formal verification techniques, SVA best practices,

and proof convergence strategies

• Partner with EDA vendors to evaluate new formal verification capabilities and drive

tool improvements that benefit the team
