Formal Verification Engineer - Senior Level

Hybrid, Kaiserslautern
Full-time
Permanent employee

Your mission

You own complex outcomes (weeks to a quarter). You turn ambiguity into a plan, drive convergence and debug to closure, and raise the bar through reusable assets and mentoring.
  • Own strategy + closure for complex blocks/IP, including quality and stakeholder alignment.
  • Set a high bar for property quality, constraint hygiene, and non‑vacuity.
  • Drive convergence with sound modeling judgment (abstraction, cutpoints/invariants, assume‑guarantee).
  • Take ownership of scope estimation and execution planning, turning unclear requests into a realistic plan (milestones, effort, risks).
  • Lead first projects technically with low-to-medium complexity, incl. mentoring others.

Your profile

  • Strong track record delivering formal outcomes on complex designs.
  • Deep SVA + modeling judgment + convergence/debug expertise.
  • Proven track record of defining a sound verification strategy independently (scoping, risk assessment, assumptions/constraints, and closure criteria).
  • Calm, crisp communicator — you prevent surprises.

What success looks like in your first ~90 days
  • You take ownership of a complex scope and create clarity (plan, milestones, decision points).
  • You unblock others through reviews/pairing and improve project reliability.
  • You own a low-to-medium complexity block end-to-end, mentor less experienced colleagues, and reliably step in as the project’s backstop when late-phase issues hit.
