In practice, the data we serve should be reliable, discoverable, and continually expanding to cover the core business concepts our products depend on. ## **About the Role** The Data Engineering team owns the data pipelines and serving APIs behind Ad Cloud — the layer that turns raw ad-serving events into high-quality, reliable, and queryable data for internal teams, products, and external customers. We are looking for a Product Manager (or Technical PM) who is comfortable in both the **technical** and the **domain** dimensions of this work — someone who can read the code and the data model, reason about a pipeline or an API contract, *and* understand what a data-quality control, an attribution correction, or a cost reconciliation actually means to the business. You will own a well-scoped set of data products first — the customer data platform, the data query/serving APIs, and the data-quality and reconciliation layers built on top of them — and grow into larger, multi-system ownership over time. ## **What You Will Do** ### **Product Design & Delivery** - Own the full lifecycle of well-defined data products — the customer data platform, the data query/serving APIs (including agent-facing interfaces), and the data-quality, control, and reconciliation layers built on top of them. - Write clear PRDs and design docs covering user flows, key states, edge cases, and acceptance criteria. - Contribute to system-architecture mapping and API contracts, with guidance from senior leadership on the largest decompositions. - Balance feature scope against release timelines and data-reliability commitments. ### **Specification & Execution** - Write functional specs engineers can build from — request/response shapes, error handling, and state-transition behavior for owned workflows; API-level details worked out together with engineering. - Break initiatives into staged, dependency-aware milestones across large-scale batch/streaming data pipelines and the serving layer. - Work directly with engineering on implementation trade-offs and resolve product-scope decisions; escalate architectural concerns appropriately. ### **Domain & Data Quality Ownership** - Build a working understanding of the domain — audience data, ad-serving events, attribution, delivery controls (e.g. frequency and spend capping), and cost/performance reconciliation — and how they are exposed to consumers through query tooling and APIs. - Treat data quality, reliability, integrity, accessibility, and understandability as first-class product outcomes; define the metrics and guardrails (SLO, freshness, observability) that hold them. - Represent the team's data to downstream consumers (internal teams, partners, external customers) and translate their needs back into pipeline and API requirements. ### **Agentic AI in the Product Workflow** - Design, prototype, and help ship agentic AI workflows and features where they fit the team's products; rapidly turn concepts into working prototypes using AI-assisted tooling. - Use AI/LLM tools daily as part of how you spec, investigate data, and orchestrate delivery. ### **Cross-Functional Collaboration** - Translate business requirements into specs for your domain and drive decisions within scope. - Support phased rollouts with feature gating and pre-release alignment for any customer-visible data change. - Coordinate across a distributed team and with cross-functional engineering, optimization, and finance functions. ## **What You Will Need** ### **Minimum Qualifications** - 2–4 years in product roles with demonstrated ownership of requirements, prioritization, and delivery (data-platform, API, or infrastructure products preferred). - Technical literacy strong enough to read code and reason about data models, pipelines, and API contracts — you don't need to ship production code, but you must be able to follow it and spec against it. - Ability to write clear functional specs, including request/response shapes and API contracts. - Experience decomposing feature scope into staged, dependency-aware milestones. - **Agentic AI (must-have):** built, prototyped, or shipped at least one working agentic AI workflow or feature, with daily fluency in AI/LLM tools. - Fluent English and Mandarin, written and spoken. ### **Nice to Have** - Domain background in AdTech / MarTech / data platforms — customer data platforms, attribution, ad-serving events, delivery controls, or cost/billing reconciliation. - Familiarity with data-engineering stacks (distributed batch/stream processing, workflow orchestration) and SQL. - Experience with multi-tenant platforms, API partnerships, or third-party measurement/attribution (MMP) integrations. - Comfort with Agile/Scrum delivery in a distributed team. *Appier is an equal opportunity employer.
