Partner closely with developers, product managers, and engineering leaders to influence decision-making early and often.

Guide and mentor junior engineers, helping raise the capability and quality mindset of the entire team.

We're looking for someone who is energetic about doing things better, pushing boundaries, and owning the testing craft.
