What you’ll need

Qualifications

Working Structure

You’ll work as part of a two‑person consulting team alongside a Quality Transformation Lead who handles organizational process improvement and leadership communication. Your focus is technical execution and capability building. This structure allows you to do deep technical work without the organizational strategy and change management responsibilities.

Ideal Candidate

You’re a senior technical specialist who gets energy from solving hard technical problems and seeing others grow. You’re comfortable being the technical expert on a team while someone else handles strategic conversations with leadership. You’ve worked on high‑stakes projects where integration failures have real consequences and you know how to build testing infrastructure that outlasts your engagement.
