At Liftoff, we’re solving a core challenge for mobile apps: growth. We build machine learning and big data technology that predicts which apps users will enjoy, connecting them in a meaningful way. Our systems process over 4 million requests per second and interact with more than a billion users weekly, operating at a scale seen only in the largest tech companies. We’re profitable, innovative, and experiencing rapid growth.

We’re looking for a staff-level analytics engineer to lead high-impact data products and our BI/modeling stack, partnering across Supply to ship reliable, cost-efficient, and scalable solutions. You’ll be self-directed, help set technical direction, and drive multi-quarter epics to completion while mentoring others.

This role is office-based with 3 days in the office each week, and the required location is Beijing (Guomao).

• Own & deliver cross-team analytics epics end-to-end (often multi-quarter): scoping, design, implementation, rollout, and adoption, with minimal oversight
• Set technical direction for our analytics/BI layer (Looker + dbt + Trino/Spark) and data products; lead design reviews and establish guardrails (cost, reliability, privacy, inclusion)
• Model and govern data: design stable contracts (schemas/SLAs), manage lineage, and evolve domain models that unlock self-service and performance at scale.
• Optimize performance & cost across engines (Trino, Spark/Databricks): plan-level analysis, join/partitioning strategies, aggregation layers, caching/materialization; set SLOs with monitoring/alerting.
• Raise the bar on engineering quality: testing, CI/CD, documentation, privacy/security, on-call hygiene; lead incident reviews and drive permanent fixes.
• Mentor & multiply: coach engineers/analysts, delegate effectively, and contribute to recruiting while holding the bar.

• Education: Bachelor’s degree or higher in Computer Science or a related technical field, or equivalent practical experience.
• Experience: 8–12+ years in data/analytics engineering or adjacent DE/BI roles, including 5+ years owning production semantic models & transformations and 3+ years leading cross-team initiatives end-to-end.
• SQL & performance: Expert SQL with the ability to read/act on query plans (distributed + warehouse). Proven wins on TB-scale data (e.g., ≥2× latency reduction or ≥30% cost savings) via partitioning, file formats, pruning, aggregations, and caching/materialization
• dbt at scale: Operated mid-to-large dbt projects (≈100+ models), using incremental models, tests, exposures, macros/packages, CI/CD, and data contracts; strong documentation and naming standards.
• Looker semantic layer: Owned LookML modeling across multiple domains; shipped governed explores/measures for 100+ users, with version control, code review, release process, and change management that enable self-service analytics.
• Engines & storage: Hands-on with Trino/Presto and/or Spark/Databricks (distributed plans, join strategies, partitioning, autoscaling); comfortable with Parquet/Iceberg table layouts and query-aware modeling.
• Reliability & governance: You set SLOs for BI/analytics surfaces, establish monitoring/alerting, manage lineage & SLAs, and run post-incidents to land permanent fixes.
• Leadership: Self-directed; sets technical direction for a domain, drives multi-quarter epics, mentors multiple engineers/analysts, leads design reviews, and raises the hiring/promo bar.
• Software fundamentals: Proficient Python and data tooling; strong testing, CI/CD, code review hygiene; privacy/security awareness.
• AI/LLM enablement: Experience designing or integrating AI-assisted analytics (e.g., chat-to-SQL over a semantic layer, RAG on dbt/Looker docs) with guardrails for access control/PII and an evaluation plan; can quantify adoption or ticket reduction.

• Ad-tech domain expertise (RTB auction dynamics, mediation, attribution, and LTV).
• Production ops for analytics infra: GitOps (Argo CD), IaC (Terraform), Kubernetes-based data services; incident playbooks for data/BI.
• Streaming & CDC: Kafka/Kinesis with Flink or Spark Structured Streaming to power near-real-time analytics.
• JVM stack: Scala/Java for Spark jobs/UDFs or high-throughput data services.
• Feature/ML data interfaces: feature marts or stores (e.g., Feast), batch/online syncing, model telemetry hooks.Privacy & governance at scale: row/column-level security, tokenization, policy-as-code; familiarity with GDPR/CCPA impacts.
• Data observability & lineage tooling:  Datadog, Prometheus/Grafana, OpenLineage/DataHub/Amundsen; automated freshness/volume/uniqueness checks.
• Experimentation: Experience building the foundations for A/B testing — event definitions, consistent metrics, and safeguards for valid results.

Multi-cloud / cross-region analytics deployments; Iceberg/Hudi table maintenance (compaction, vacuum, manifest tuning).

Location:This is a hybrid (3 days/week in-office) role. Our Beijing office is located in Guomao.
