Senior Software Development Engineer (Amazon)

Job Description
Our EBMS Real-Time Data Platform team is looking for a Software Development Engineer with hands-on experience in Apache Flink, Amazon Kinesis, and Java to build and maintain our real-time BMS data pipeline that ingests telemetry from thousands of global building management systems. The engineer will be responsible for the full lifecycle of stream-processing applications; from design and development through deployment and production operations with a focus on delivering 99% system uptime, comprehensive observability, and fault-tolerant architecture.
 

Primary Responsibilities
• Design, develop, and optimize Apache Flink stream-processing applications for real- time BMS data ingestion, transformation, and enrichment.
• Build and maintain Amazon Kinesis Data Streams infrastructure including shard management, auto-scaling policies, and dead-letter queues.
• Implement comprehensive observability: CloudWatch/Grafana dashboards, distributed tracing, structured logging, and tiered alerting (P1/P2/P3) across the full pipeline.
• Troubleshoot and resolve production issues across the ingestion-to-serving stack (Kinesis, Flink, DynamoDB, S3, Athena)
• Develop and maintain Infrastructure-as-Code (CDK/CloudFormation) for all pipeline components, ensuring repeatable and auditable deployments.
• Implement data quality monitoring including record count validation, schema drift detection, and null-rate anomaly detection across all sites.
 

Job Qualifications
The ideal candidate has strong software engineering fundamentals and a passion for building reliable, high-throughput distributed systems. They must be detail-oriented,comfortable operating in an on-call environment, and able to communicate effectively with both technical and non-technical stakeholders.
 

Required:
• Bachelor’s or Master’s degree in Computer Science, Software Engineering, or equivalent technical field.
• Strong proficiency in Java (primary) with production-level experience building and deploying applications.
• Hands-on experience with Apache Flink or equivalent stream-processing framework (Spark Streaming, Kafka Streams).
• Experience with Amazon Kinesis Data Streams or similar distributedmessaging/streaming platform.
• Demonstrated experience building and operating systems with 99%+ uptime SLAs.
• Solid understanding of distributed systems concepts: fault tolerance, exactly-once semantics, checkpointing, backpressure management.
• Experience with AWS services: DynamoDB, S3, Athena, CloudWatch, IAM.
• Proficiency with Infrastructure-as-Code (CDK, CloudFormation, or Terraform).

Preferred:
• Experience with MQTT, Haystack protocol, or Niagara N4 (building automation / IoT).
• Familiarity with Apache Avro, AWS Glue Schema Registry, or similar schema management tools.
• Experience with Grafana, CloudWatch Logs Insights, or distributed tracing frameworks.
• Knowledge of chaos engineering practices and tools.
• Prior experience with BMS (Building Management System) or IoT data pipelines.
• Python proficiency for scripting, data analysis, and tooling.
