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.
