Senior Product Manager (Ad Cloud Platform)

We are looking for a Product Manager who combines sharp product instincts with real software engineering fluency to own and drive complex, multi-system SaaS products within Appier's Ad Cloud platform. You will be responsible for defining, designing, and shipping products that span multiple backend systems, API integrations, and cross-functional stakeholders. This isn't a wireframe-and-handoff role, you'll write functional specs with API-level precision, navigate system-of-record ownership across 5+ services, and make architectural trade-off decisions alongside engineering leads.

Responsibilities

Own the end-to-end product lifecycle for complex SaaS modules; Author whitepaper-grade product design documents; Define system-of-record ownership, API contracts, and data flow directions; Make scope and trade-off decisions across milestones; Write functional specifications at the API-level; Define status matrices with explicit state transitions and cross-system sync behaviors; Decompose large product initiatives into staged delivery plans; Work directly with engineering teams on implementation trade-offs; Use AI agent tools as daily productivity multipliers; Evaluate how AI/LLM capabilities can be embedded into the product; Prototype product concepts rapidly using AI-assisted development tools; Serve as the central product authority across engineering, design, customer success, and sales teams; Drive decision-making on blocking items; Manage product rollouts with permission controls, feature gating, and phased go-live strategies

Requirements

2-5 years as a Product Manager, Technical PM, or Software Engineer transitioning to product; Solid software development background, ability to read and reason about code, REST API design, database schemas, state machines, and system architecture diagrams; Demonstrated ability to write precise technical specifications including API contracts, entity relationship models, status transition matrices, and interoperability flow diagrams; Experience with complex product decomposition, breaking down a 50+ feature scope into staged milestones; Working fluency with AI/LLM tools; Excellent communication skills in both English and Mandarin; Hands-on experience with modern AI agent frameworks such as Claude Code, Cursor, Codex, or building AI-powered product features

Nice to have

Background in AdTech, MarTech, or enterprise SaaS platforms with multi-tenant architectures; Experience managing products that involve third-party system integrations and API partnerships; Familiarity with Agile/Scrum delivery but comfort operating in a hybrid model where staged milestone planning coexists with sprint-level execution
