Infrastructure Engineer

Job Summary

We are seeking a Cloud Infrastructure / Platform Engineer to design, build, and operate highly scalable cloud infrastructure and platform services. This role is ideal for a hands-on engineer who combines strong cloud infrastructure expertise with recent production software development experience.

The ideal candidate will have deep experience with AWS, Terraform, Linux, Docker, Kubernetes/EKS/ECS, cloud networking, distributed systems, and CI/CD, along with the ability to develop and maintain production-quality applications and platform services using Node.js/TypeScript and/or C#.

This is not a traditional DevOps or infrastructure administration role. The engineer will be expected to write and maintain production code recently, while also owning infrastructure, platform reliability, scalability, and operational excellence.

Key Responsibilities

• Design, build, and maintain scalable AWS cloud infrastructure and platform services.


• Develop and maintain production software using Node.js and TypeScript and/or C#.


• Build reusable and maintainable infrastructure using Terraform and Infrastructure-as-Code.


• Design and manage multi-environment cloud infrastructure across development, testing, and production.


• Deploy, operate, and troubleshoot containerized workloads using Docker and Kubernetes, EKS, and/or ECS.


• Work extensively in Linux-based environments such as Ubuntu, Amazon Linux, RHEL, or Alpine.


• Design and troubleshoot cloud networking components including VPCs, DNS, load balancing, routing, security groups, and service connectivity.


• Build and support distributed systems capable of handling high-volume data ingestion and real-time telemetry.


• Implement event-driven and streaming architectures using technologies such as Kafka, Kinesis, or other messaging/pub-sub platforms.


• Develop and maintain automated CI/CD pipelines with testing, quality controls, deployment gates, and repeatable environment promotion.


• Monitor and troubleshoot production systems using Datadog, CloudWatch, Splunk, or comparable observability platforms.


• Participate in incident response, root-cause analysis, performance optimization, and reliability improvements.


• Design solutions that support backward compatibility and long-lived connected devices/machines.


• Develop technical documentation covering architecture, operational procedures, incidents, technical decisions, and system tradeoffs.


• Collaborate with software engineers, architects, and platform teams through design reviews, code reviews, and architecture discussions.


• Mentor engineers on cloud-native architecture, infrastructure patterns, software development, and production operations.
