• Track record of improving DevEx metrics in the right direction (DORA, DX insights, CSAT)
• Strong instinct for finding systemic friction and solving it pragmatically
• Proven ability to operate independently in a distributed team across a timezone gap
• Hands-on experience applying AI tooling to real engineering workflows
• Based in EST timezone
