    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 distributed

    messaging/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.

    We offer*:

    • Flexible working format - remote, office-based or flexible
    • A competitive salary and good compensation package
    • Personalized career growth
    • Professional development tools (mentorship program, tech talks and trainings, centers of excellence, and more)
