Senior Technical Product Manager

Single Grain•Los Angeles, CA

2d•$120,000 - $150,000•Remote

About The Position

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.

Requirements

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 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.

Nice To Haves

Ideal: early-stage / growth-stage; developer tools, API, infrastructure, or AI products.

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.
