My SaaS product is already deep in development and the immediate mandate is to refine and rigor-test the remaining features before launch. I need a hands-on product manager who can take full ownership of the development stage, with special attention on integrations and cross-platform compatibility. The groundwork is partly done—market research, high-level vision, and core success metrics are in place. What’s missing is the rigorous execution muscle that keeps engineering, design, and marketing aligned while turning user stories into polished, reliable functionality. I expect you to maintain the roadmap, ruthlessly prioritise tickets, and translate every integration requirement into clear, testable acceptance criteria. Close collaboration with developers on API contracts, third-party services, and mobile/desktop parity will be an everyday task, as will quick data dives to validate hypotheses and spot regressions early. Key deliverables • Updated, prioritised roadmap that reflects integration milestones • Compatibility matrix covering browsers, devices, and third-party services • End-to-end test plan with pass/fail metrics for each integration • Weekly stakeholder updates summarising progress, risks, and next steps Success means the feature set feels seamless regardless of platform, performance stays within target response times, and there are no surprises when we flip the switch for beta users. If you thrive on translating strategy into shippable quality, I’m ready to share current backlogs, user analytics, and access to the dev environment so we can get started right away.
