Platform Engineer

Job Overview

We’re hiring a Platform Engineer to help design, build, and maintain the foundation our teams rely on every day. You’ll join our Platform team, which supports security, core infrastructure, and DevX across Cogna. Your focus will be enabling scalability, reliability, and automation of our Azure-based environments—so other teams can move faster, safer, and with greater autonomy.

Key Responsibilities

• Design and maintain cloud infrastructure in Microsoft Azure to support internal platforms and product delivery.
• Work within and contribute to our Python/Go codebase.
• Develop and evolve infrastructure-as-code (IaC) using tools such as Terraform.
• Own CI/CD pipelines and DevX workflows in collaboration with the dev teams.
• Implement and monitor security controls, identity management (Entra ID), and network configurations.
• Support container orchestration, and workload deployment using Kubernetes and AKS.
• Improve observability by implementing logging, monitoring, and alerting systems (e.g. Azure Monitor, Datadog, etc.).
• Partner with internal teams to improve resilience, automate toil, and reduce lead time to deployment.
• Drive root cause analysis and reliability improvements from incidents.

Required Qualifications

• Production-grade coding experience: Proficient in writing maintainable, testable, and scalable code in real-world, production environments.
• Language fluency in Python and/or Go is a plus, but strong engineers with deep experience in comparable languages are welcome.
• Strong foundational software engineering skills: Solid grasp of computer science fundamentals such as data structures, concurrency, time/space complexity, performance and systems design.
• Systems-level thinking: Comfortable reasoning about how things work under the hood—networks, operating systems, compilers, storage systems, or distributed services.
• Infrastructure as Code and automation: Experience with tools like Terraform, Pulumi, or equivalent for managing cloud-native infrastructure declaratively and repeatably.
• Stack Familiarity: We use Azure, Bazel, GRPC, Temporal, Postgres and Kubernetes (AKS). Prior experience or expertise with these is a plus.
• Security-first mindset: Deep appreciation for secure-by-default design. Familiar with principles like least privilege, secrets management, threat modeling, and how to embed security controls into infrastructure and CI/CD pipelines.
• Cross-functional collaboration: Comfortable partnering with other engineers, product managers, sal...
