Job Description:

Uber’s Developer Platform Organization is looking for a Staff Software Engineer with deep expertise in Java to lead and execute the strategic vision for Uber's next-generation Java platform. This is a high-impact, company-scoped technical leadership role. You will be responsible for far more than the Java Platform team's roadmap; your mission is to elevate the capabilities of every Java developer at Uber and deepen Uber's engagement with the broader Java open-source community.

Job Responsibility:

  • Set Java Technical Direction: Own the multi-year Java platform roadmap (runtime, build, tooling, AI-assist)
  • Translate future Java features (new JDK, virtual threads, etc.) into concrete adoption plans to boost throughput and cut costs, influencing architecture across thousands of services
  • Accelerate Java Developer Velocity: Design and ship next-gen platform abstractions (TaskGraph, virtual-thread containers, reactive I/O) and opinionated 'golden-path' frameworks (observability, circuit-breakers, AI code generation) to simplify development
  • Partner with teams to reduce build times, test flakiness, and onboarding friction
  • Enable Storage, Search & Data with Open Source: Act as Uber's senior liaison to critical Java OSS communities (OpenJDK, Cassandra, Lucene, Kafka, Pinot, Hive/Spark)
  • Identify and address upstream gaps, contribute fixes/features, reduce Uber-specific forks, and establish a structured OSS engagement model (office hours, contribution guidelines, sponsorship, conferences)
  • Drive JVM Performance & Cost Efficiency: Lead benchmarking and continuous profiling to optimize JVM tuning, GC strategy, and frameworks
  • Quantify cost savings for leadership and champion memory- and CPU-efficient design through guidelines and automated analysis
  • Mentor, Grow, and Lead: Mentor Staff/Senior Engineers
  • Conduct high-quality architecture/design reviews
  • Represent Java Platform in company-wide forums and build partnerships with leaders (Directors, VPs) and cross-functional teams (Product, Finance, Legal) to align platform investments with business results

Requirements:

  • Bachelor's Degree in Computer Science or a related field (or equivalent experience)
  • 10+ years of full-time engineering experience
  • Demonstrated track record of driving large-scale, cross-organizational technical initiatives from concept through production
  • Proven ability to influence engineering direction at the organizational level
  • Systematic problem-solving approach and knowledge of algorithms, data structures, and complexity analysis
  • Strong understanding of distributed systems or stream processing
  • Proficient in at least one programming language, such as Golang, Java, C#, or C++

Nice to have:

  • 8+ years of experience building and managing large-scale distributed systems
  • Expert-level Java proficiency, including deep knowledge of the JVM (HotSpot / GraalVM), garbage collectors (G1, ZGC, Shenandoah), and memory model
  • Hands-on experience with JVM performance tooling: async-profiler, JFR/JMC, heap dump analysis, and continuous profiling pipelines
  • Direct open-source contribution history — ideally committer or contributor status in OpenJDK or a major Java ecosystem project (Netty, Micronaut, Quarkus, Gradle, Apache Kafka, Apache Cassandra, Lucene, etc.)
  • Background in Storage, Search, or Data platform engineering — understanding the JVM-rooted operational concerns of systems like Cassandra, Elasticsearch, Kafka, Pinot, or Spark
  • Strong technical writing and communication skills
  • ability to produce crisp Engineering Design Documents and present to executive audiences
  • Leveraging AI/GenAI technologies to streamline engineering workflows, including the automation of routine development tasks and the enhancement of code quality
  • Great sense of ownership and a proactive bias towards action
What we offer:
  • Eligible to participate in Uber's bonus program
  • May be offered an equity award & other types of comp
  • All full-time employees are eligible to participate in a 401(k) plan
  • Eligible for various benefits
