Principal Backend Engineer (Go)

What are we building?

FunnelStory is building the GTM context graph — the infrastructure layer that lets revenue teams and AI agents reason over live customer intelligence. We fuse GTM data from many systems, maintain durable account truth, and power permissioned actions and agents on top.

Backend: Go, PostgreSQL, Docker, AWS; enterprise and on-prem deployments.

Opportunity

• Own major backend work across the data platform (connections, ETL/reverse ETL, sync) and the agent layer (workflow runtime, reliability, usage/billing)
• Solve hard product problems — incremental refreshes, reconciliation, integrations at scale
• Shape architecture, engineering process, and culture with the founders
• Work closely with the team to design and ship new features
• Mentor others and help lead as we grow

Who are you?

• Opinionated, accountable, and ownership-driven
• You tackle unknown problems and find practical solutions; you communicate clearly
• You challenge weak ideas and care about products customers can trust
• You use AI tooling to ship faster — and you still write clean, reliable code (not slop)
