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)
  • Active tech communities with regular knowledge sharing

Why it works

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
