Senior Technical Product Manager

Single Grain combines marketing services, software, and AI. The Senior Technical Product Manager will own product judgment for Single Brain and the API Gateway, defining priorities, metrics, hypotheses, and engineering direction. The role also leads customer discovery, analytics and instrumentation, sprint kickoffs, roadmap prioritization, and build-measure-iterate cycles.

Responsibilities:

• 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 worked
• Own customer discovery — talk to customers often; separate loud requests from high-leverage opportunities
• Own product analytics and instrumentation quality; no major initiative ships without a measurement plan
• Review launches against real results and choose iterate, expand, revert, or move on
• Keep the integration / Gateway roadmap intentionally prioritized
• Protect the team from low-impact or poorly defined work

Requirements:

• You should be an advanced AI user
• Experience owning a technical software product (APIs, integrations, auth, data fluency)
• Metrics you personally owned and improved — with diagnosis, not feature lists
• Sprint leadership / prioritization with engineering teams
• Product analytics and instrumentation ownership (PostHog, Amplitude, Mixpanel, or similar)
• Advanced daily AI workflows for product work
• High-agency ownership: you set roadmap direction; you are not a conduit or Jira admin
• Ideal: early-stage / growth-stage; developer tools, API, infrastructure, or AI products
