Formal Verification Engineer - Senior Level

Full-time

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.
• Proven track record of defining a sound verification strategy independently (scoping, risk assessment, assumptions/constraints, and closure criteria).

• 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.

About us

LUBIS is a fast-growing German startup redefining how the semiconductor industry works. We tackle one of its hardest challenges — ensuring complex chips work flawlessly before they’re built. Our mission is simple: to transform verification from a craft into a system. By structuring how teams work and automation we make chip design faster, reliable, and bug‑free. LUBIS isn’t just improving the process — we’re defining how verification is done.
