Posted on Jan 14, 2026

We’re building Reflow, a workforce and workflow intelligence platform that helps teams understand and improve how work gets done. We’re at a stage where product decisions, execution, and delivery are inseparable — which means this role owns what we build, why we build it, and how it actually ships.

We’re looking for a founding Product Manager who can operate end-to-end: product strategy, prioritization, execution, and delivery. This is a hands-on role for someone who has built in very early-stage environments and thrives without guardrails.

What you’ll do

Own product direction and outcomes:

  • Own product direction, roadmap, and prioritization — making tradeoffs across customer value, speed, and technical constraints.
  • Turn ambiguous goals into clear problems, scopes, and shipped solutions.
  • Be accountable for outcomes, not artifacts.

Run product execution and operations:

  • Drive planning, sequencing, and timelines with engineering.
  • Manage dependencies, unblock progress, and keep delivery on track.
  • Own release planning, testing, rollouts, and post-launch learning.

Be deeply hands-on:

  • Write product specs, workflows, and acceptance criteria.
  • Review builds, test flows, and iterate with engineers in real time.
  • Make fast calls when things are unclear or breaking.

Stay close to customers and partners:

  • Talk to customers constantly: discovery, validation, onboarding, and support.
  • Translate feedback into priorities and concrete product changes.
  • Support partner setup, onboarding, and early integrations when needed.

Build early product systems:

  • Establish how roadmap, prioritization, and execution work.
  • Create lightweight processes that increase speed, not bureaucracy.
  • Document decisions and patterns so the product can scale.

Who you are

  • 5+ years of product management experience, with at least part of that in a very early-stage startup.
  • Former founder, founding PM, or first/early product hire is strongly preferred.
  • Proven ability to ship real products in ambiguous, resource-constrained environments.
  • Comfortable owning execution details, not delegating them away.
  • Strong technical and product judgment; engineers trust your calls.
  • Bias toward action, clarity, and momentum.

Bonus points

  • Experience with B2B SaaS, data, analytics, workflow, or platform products.
  • Technical background or deep technical fluency.
  • Experience owning integrations or partner-facing features.

Why join Reflow

  • Founding-level ownership over product and execution.
  • Direct access to founders and customers, zero layers.
  • Real influence over product direction, roadmap, and delivery.
  • Opportunity to grow into Head of Product as the company scales.
  • Flexible setup (contract or full-time), high trust, high expectations.

This is a role for someone who wants to build the product, not manage around it — and who’s excited to do so in a true early-stage startup.
