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. 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.
