Researches the right approach before building, and chooses the simplest thing that will actually work
 
Cares about reliability — this is mission-critical infrastructure where downtime means missed shipments for real brands
 
Hungry, committed, and "all-in" on an early-stage startup pace. Not 9-to-5, not 996 — reachable when things break, and honest about what that requires Communication Clear, direct communicator who can talk to non-technical customers when needed and translate their workflows into software

Hybrid in Brooklyn, NY (WeWork). Strong preference for in-person most of the week

Experience at Flexport or a comparable logistics-adjacent company
 
Familiarity with Supabase, Next.js, or other modern BaaS stacks
