Formal Verification Engineer - Professional Level

Hybrid, Kaiserslautern
Full-time
Permanent employee

Your mission

You own a defined formal deliverable end‑to‑end (days to a few weeks). You work independently in known contexts, drive proof closure, and hand over sign‑off artifacts that customers trust.

  • Own a block/area: clarify requirements, co-define the verification strategy (scope, risks, approach), execute, and close.
  • Produce maintainable SVA and a clean formal environment (constraints/assumptions with good hygiene).
  • Debug efficiently, partner with designers on fixes, and prevent regressions.
  • Keep stakeholders aligned with crisp updates and decision-ready evidence.

Your profile

  • Proven experience delivering formal results on non‑trivial RTL (e.g., caches, pipelined processors, DMAs, NoCs).
  • Strong SVA skills and hands-on formal tool experience (e.g.: Jasper, VCF, Questa Formal/Onespin).
  • Reliable end‑to‑end ownership in a defined scope.

What success looks like in your first ~90 days
  • You nail our onboarding bootcamp and earn the team’s trust: you apply the LUBIS way of working and consistently ship clean, reviewable outputs.
  • You engage confidently in scoping and planning with the team: you clarify open questions early, surface risks, and help translate scope into a concrete plan.
  • You own a deliverable end‑to‑end in a defined area and ship it without a “rescuer”.

Where this leads
The natural next step is our Senior Formal Verification Engineer role — leading customer engagements, owning formal architecture decisions, mentoring Associates and Professionals, and shaping how LUBIS approaches new verification problems. We make that path concrete: review cycles, customer-lead rotations, and clear competency milestones.
