Staff Backend Engineer

Role Description

LiveRamp is the data collaboration platform of choice for the world’s most innovative companies. The Activations Back End team is responsible for the bulk of big data processing that powers LiveRamp’s primary activation product, which delivers hundreds of millions in annual recurring revenue. Our systems process over one hundred thousand batch jobs per day, ranging in size from gigabytes to over 100 terabytes, and power distributions to hundreds of downstream destinations. Cumulatively, our systems process multiple exabytes per year.

You will:

• Lead the design and evolution of a petabyte‑scale activation platform, pushing it toward a delta‑first, cache‑aware, and cost‑efficient architecture.
• Shape end‑to‑end technical strategy for major areas of Activations Back End (e.g., matching/delta computation, job orchestration, delivery pipelines), from design through rollout and long‑term maintenance.
• Architect and build big data pipelines using Apache Spark/Dataproc, SingleStore, Kubernetes/GKE, and streaming systems (e.g., Pub/Sub, Redpanda/Kafka) where appropriate.
• Use workflow engines such as Temporal and Cadence to orchestrate complex, long‑running workflows with robust retry, compensation, and observability, and define patterns other engineers can reuse.
• Design for multi‑tenant fairness and scalability, ensuring small, latency‑sensitive jobs stay fast while large backfills and bulk workflows do not starve the system, via job classification, queueing, and rate‑limit–aware scheduling.
• Drive performance and cost optimization for petabyte‑scale workloads: reduce duplicate processing, improve cache hit rates, tune cluster sizing and autoscaling policies, and set and track SLOs.
• Lead production excellence: own critical services in production, coordinate incident response and postmortems, and drive structural fixes that meaningfully reduce operational load and risk.
• Infuse AI into how we build and operate: evaluate and adopt AI‑enhanced tooling (for coding, design exploration, data analysis, and operational debugging) and help define best practices.
• Mentor and level up other engineers through design/code reviews, pairing, and technical guidance, and represent Activations Back End in cross‑team architecture forums and external venues.

Your team will:

• Re‑architect Activations Back End to be cloud‑forward and multi‑regional, taking advantage of SingleStore and other modern data warehouses to replace legacy Spark‑heavy flows where it makes sense.
• Deliver high‑throughput, low‑latency activation by combining:
  • SingleStore‑backed state and delta computation,
  • Spark/Dataproc for the heaviest batch workloads,
  • Streaming infrastructure (e.g., Redpanda/Pub/Sub) for event‑driven and incremental deliveries.
• Build smarter orchestration and scheduling using Temporal/Cadence and queueing services to:
  • Classify jobs (latency‑critical vs. throughput‑heavy vs. background),
  • Route them through multi‑queue schedulers and capacity pools,
  • Respect destination‑specific rate limits and SLAs.
• Eliminate duplicated work through config canonicalization and caching so identical or similar jobs across customers share heavy computation.
• Collaborate closely with partner teams (Identity, Data Foundation, Activations Fullstack, Integrations/OPI) to deliver end‑to‑end improvements in activation reliability, speed, and observability, and continuously raise the bar on operational excellence.

Qualifications

• AI‑enabled development experience, or strong excitement to learn and grow in using AI‑enhanced development tools (e.g., code assistants, agents for log/metrics analysis, AI‑supported design and review) and help others use them effectively.
• 5+ years of experience writing and deploying high‑quality production code in a modern language (e.g., Java, Go, Scala, or similar), including owning complex systems in production.
• Have led the design and delivery of large‑scale distributed or big data systems with clear business impact (e.g., major latency/cost improvements, substantial reliability gains, or large new capabilities).
• Strong data engineering and SQL skills: comfortable modeling data, writing and optimizing complex queries on very large tables, and reasoning about performance, correctness, and cost.
• Deep experience owning end‑to‑end data pipelines: ingestion, transformation, orchestration, failure handling, and observability, not just individual jobs or microservices.
• Comfortable working in a cloud environment (ideally GCP) and with containerized workloads (Kubernetes/GKE or similar); you understand how infra choices impact performance, cost, and reliability.
• Able to define and drive technical strategy: break down multi‑quarter problems, evaluate tradeoffs, align stakeholders, and deliver incremental value along the way.
• Excellent communication and collaboration skills; you can influence across teams and disciplines and drive consensus on complex technical decisions.
• Demonstrated ability to mentor and grow other engineers, give effective feedback, and create space for others to contribute.
• Comfortable with ambiguity and deeply inquisitive: you ask “why” and “what if” and convert those questions into concrete experiments and system changes.

Requirements

• Preferred skills (nice to have):
  • Google Cloud Platform (GCP): GCS, Dataproc, GKE, Pub/Sub, BigQuery, IAM.
  • Workflow orchestration: Temporal or Cadence; Airflow or similar systems for long‑running, failure‑prone workflows.
  • Big data & warehouses: Apache Spark (or Dataproc) for large‑scale batch processing.
  • Experience with data warehouses such as SingleStore, BigQuery, Snowflake, or similar.
  • Streaming systems: Kafka/Redpanda, Pub/Sub, or equivalent event/streaming platforms, especially for high‑volume or incremental data processing.
  • Experience designing multi‑tenant systems that enforce rate limits, fairness, and SLAs across many customers and destinations.
  • Strong background in performance and cost optimization for large‑scale data workloads (e.g., 10–100x speedups, significant compute cost reductions).
  • Prior experience working on advertising, marketing, or data activation platforms or other systems where data correctness, timeliness, and scale are all critical.
