How We Work Bold in how we dream and innovate Responsive to feedback, challenges and opportunities Accountable for results and best in class outcomes Visionary in future focused problem‑solving Exceptional in execution and impact Role Overview We are seeking an experienced Senior Architect to lead the design and evolution of enterprise‑scale distributed systems supporting 50M+ connected sensors and high‑volume event processing pipelines . This role is critical to building and operating mission‑critical backend platforms that process millions of events per second across both synchronous and asynchronous architectures , with stringent requirements for scalability, reliability, security, and performance . The ideal candidate brings a proven track record of architecting and scaling production‑grade systems at extreme scale , along with the ability to drive technical strategy, governance, and cross‑functional alignment in a complex enterprise environment. Key Responsibilities Architecture & System Design Define and lead the architecture of large‑scale distributed systems capable of ingesting and processing high‑velocity data streams from 50M+ sensors Design resilient systems across synchronous (API‑driven) and asynchronous (event‑driven, streaming) paradigms Establish architectural standards for scalability, fault tolerance, and performance optimization Data Platform Engineering Architect real‑time and batch data pipelines for high‑throughput ingestion, transformation, and storage Drive design decisions across streaming, processing, and storage layers to ensure optimal performance and cost efficiency Enable support for time‑series, event‑driven, and analytical workloads Technology Strategy & Governance Define and enforce enterprise architecture principles, standards, and best practices Evaluate and guide adoption of modern data technologies, including distributed messaging systems (e.g., Kafka, Pulsar), scalable data stores (e.g., Cassandra, DynamoDB, Bigtable, ClickHouse, Elasticsearch), stream and batch processing frameworks (e.g., Flink, Spark, Beam) Ensure alignment with security, compliance, and data governance requirements Scalability, Reliability & Observability Establish and operationalize SLAs, SLOs, and error budgets Design for high availability, multi‑region resilience, and disaster recovery Implement enterprise‑grade observability frameworks (monitoring, logging, tracing) Leadership & Collaboration Partner with engineering, product, security, and data teams to align architecture with organizational objectives Provide technical leadership, mentorship, and architectural oversight across multiple teams Lead design reviews and ensure adherence to architectural standards Required Qualifications Experience 10+ years of experience in distributed systems and backend architecture Demonstrated success in scaling systems to 50M+ connected devices/sensors, or comparable high‑scale environments (e.g., IoT, telecom, fintech, ad‑tech, infrastructure platforms) Proven experience with high‑throughput event‑driven architectures in production environments Technical Expertise Deep understanding of distributed systems concepts, including CAP theorem, consistency models, and trade‑offs; partitioning, replication, and sharding strategies; event delivery semantics (at‑least‑once, exactly‑once, idempotency) Strong experience with streaming and messaging systems (Kafka, Pulsar, or equivalent), real‑time and batch processing frameworks, scalable NoSQL and analytical data stores System Design & Engineering Expertise in designing low‑latency, high‑throughput APIs, event‑driven and asynchronous processing systems, multi‑region, highly available architectures Strong programming proficiency in one or more of: Go, Java, Scala, or Rust Preferred Qualifications Experience with large‑scale IoT or telemetry platforms Familiarity with edge‑to‑cloud architectures Experience operating in multi‑cloud or hybrid environments Knowledge of enterprise security frameworks, data governance, and compliance (e.g., SOC2, ISO, GDPR) Exposure to AI/ML data pipelines and large‑scale analytics platforms Success Metrics Architecture supports billions of daily events with consistent performance and reliability Systems demonstrate horizontal scalability and fault isolation Clear separation and optimization of real‑time vs batch workloads Strong adherence to enterprise architecture and governance standards Why Proofpoint?
