Senior DevOps Engineer (AWS)

We are looking for a Senior DevOps Engineer to join a part-time healthcare project focused on building a Connected Device Data Platform that ingests biometric data (pulse, heart rate, O2, steps, accelerometer) from smartwatch wearable devices via AWS IoT Core and delivers it to a companion mobile app. The platform is in an early stage – initial AWS infrastructure has been set up, but no real devices are connected yet.

This position provides for the possibility of business trips (EU, USA) and ​has the potential to scale to a ​full-time position.



What We’re Looking For:
 

• 5+ years of hands-on AWS experience, including architecting and managing production environments
• Strong expertise in AWS IoT Core, EKS/Kubernetes, RDS (PostgreSQL), S3, CloudWatch, IAM, VPC, and networking
• Proven experience building CI/CD pipelines (GitHub Actions, CodePipeline, Jenkins, or similar)
• Solid Infrastructure-as-Code skills (Terraform preferred, CloudFormation or CDK acceptable)
• Experience with containerized deployments using Kubernetes/Docker in AWS (EKS)
• Strong scripting skills (Bash, Python) for automation and toolchain development
• Understanding of security best practices, certificate management, and encryption in AWS
• Experience working in agile teams with sprint-based delivery (2–3 week sprints)
• Great communication skills in English – ability to interact with client's PM and technical stakeholders and multi-cultural team
• Self-directed and able to make informed decisions with limited documentation
• Willing to travel to the EU and the USA for business trips

Your Responsibilities:

• Conduct an initial assessment of the existing AWS infrastructure, CI/CD pipelines, and deployment processes; provide recommendations and a prioritized improvement plan
• Manage and maintain AWS services: IoT Core (MQTT, device certificates, fleet provisioning), EKS/Kubernetes clusters, PostgreSQL (RDS), InfluxDB/Timestream, S3, CloudWatch, SNS
• Design and implement automated CI/CD pipelines (GitHub Actions or AWS CodePipeline) for build, test, and deployment workflows
• Develop and maintain Infrastructure-as-Code (Terraform, CloudFormation, or CDK)
• Set up monitoring, alerting, and logging for platform health and performance
• Support device connectivity workflows – certificate management, Infineon M5Stack edge device provisioning, MQTT broker configuration
• Implement security best practices and contribute to HIPAA compliance foundations (encryption, audit logging, access controls)
• Collaborate with the backend engineer on deployment automation and environment management (dev, staging, production)
• Provide on-call infrastructure support as the platform scales from hundreds to thousands of connected devices
• Develop automation scripts and toolchain improvements to reduce manual operational overhead

Nice to have
 

• Experience with healthcare platforms and HIPAA compliance requirements
• Familiarity with IoT device provisioning, MQTT protocols, and edge computing
• Experience with InfluxDB or AWS Timestream for time-series data
• Familiarity with FHIR data standards
• Experience supporting multi-team distributed development (different time zones and vendors)
