One-liner

Own what gets built and why across Single Brain and API Gateway — turn build → build → build into build → measure → iterate.

About the role

Single Grain combines marketing services, software, and AI. This seat owns product judgment for Single Brain and the API Gateway: which metrics matter, what is blocking them, and what engineering should build next.

Engineering owns how we build. You own what we build and why.

You report to the CTO. You work daily with a ~6-person engineering team. You do not manage that team as a people manager; you create clarity so their effort lands on the highest-leverage outcomes.

You should be an advanced AI user. Use AI for research, interview synthesis, analytics, specs, prototypes, experiment design, and competitive work so your product decisions get faster and better.

What you will own

• Identify the highest-leverage product metrics across Single Brain and API Gateway (activation, usage, retention, expansion, revenue, time-to-value, Gateway/integration adoption). • Diagnose what is limiting those metrics. • Decide what engineering should build next, with clear hypotheses and success criteria. • Run strong weekly sprint kickoffs so the team leaves knowing: what metric are we moving, what are we doing to move it, and how will we know it…
