Senior Software Development Engineer

Adobe Experience Platform (AEP) helps businesses deliver the right experience to customers at the right time. Segmentation Service plays a critical technical role in AEP’s realtime CDP. It evaluates trillions of audience segment definitions daily. These evaluations use customer profiles with behavioral and attribute data from all channels. The queries are complex and require accuracy and speed at a large scale. This senior engineering role requires extensive expertise in high-throughput, low-latency distributed systems. You will manage a wide technical area by defining architectural direction within Segmentation Service and related AEP platform teams. Your responsibilities will affect all Adobe Customer Experience Orchestration solutions. Owning this role involves delivering solutions, not just proposing them. What You’ll Do Own building and implementation of core components in the Segmentation Service engine — real-time query evaluation, incremental processing, and performance at production scale Develop query optimization and evaluation algorithms, including multi-query optimization and streaming evaluation approaches that hold up as segment complexity and profile volume grow Guide multi-functional technical initiatives across related teams, establishing architectural direction for capabilities that cross service boundaries Identify performance bottlenecks and build targeted solutions — reasoning about JVM tuning, GC patterns, serialization overhead, and data structure choices under high event load Analyze and advance core infrastructure including data ingestion, processing and storage — understanding how each impacts latency, efficiency thresholds, or failure modes at scale Build systems that degrade gracefully, instrument for observability, and take responsibility for operational behavior in production Lead architecture and code reviews — making the reasoning behind decisions clear to engineers at every level Heavily use AI to lead improved efficiency and iterate faster What You’ll Need to Succeed 10 years of software engineering experience in SaaS with a demonstrated history in distributed systems Deep proficiency in Java or Scala — including the runtime: JVM memory management, GC tuning, thread scheduling, and how allocation patterns affect tail latency at high event rates Proven ability to reason about system performance at scale — predict where a build breaks under load, profile production systems, and drive optimizations that improve real metrics Experience building or evolving query engines, stream processing pipelines, or equivalent systems where correctness and performance must coexist Practical experience with Kafka, Kubernetes, gRPC, and high-performance key-value or document databases — along with the discernment to determine when each is the appropriate choice Strong architectural thinking: understand complex, multi-service systems, identify where assumptions fail under scale, and communicate tradeoffs to technical and non-technical collaborators B.S. in Computer Science or related field, or equivalent experience, required; M.S. or equivalent practical depth preferred About Adobe Adobe empowers everyone to create through innovative platforms and tools that unleash creativity, productivity and personalized customer experiences.
