How to Land a System Development Engineer Role at Amazon: A Practical Blueprint

Your Personal Roadmap: From DevOps to System Development Engineer at Amazon

This guide is my personal opinion and is not affiliated with or endorsed by Amazon. I’ve created it as a structured roadmap for professionals moving from DevOps, Support Engineering, Systems Administration, QA Automation, or junior/mid-level Development roles into a System Development Engineer (SysDev) role at Amazon or similar top-tier tech companies. You can think of it as a living document that offers a clear pathway to gain the right technical, project, and interview-readiness skills. The content is divided into phases, with recommendations for hands-on practice, certifications, and interview tips, so you can easily pick what’s most relevant to your journey.

Before we proceed, I’d like to quote from Amazon’s definition of a System Development Engineer, which can be found here:

"While it’s difficult to describe what a System Development Engineer does at AWS, we can say that our primary role is to build software that increases operational performance and developer agility. We are DevOps thought leaders in automation and infrastructure of a service. We write code to fix bugs, automate tasks, implement monitoring, and deal with infrastructural components within the large scale systems we build. And we are the glue that keeps AWS services up and running for our customers."

1. Solidify Your Foundations

1.1 Linux and OS Fundamentals

• Deepen your understanding of Linux: file system hierarchy, permissions, basic commands, system performance monitoring, process management, and networking.

• Programming & Scripting: Develop in-depth knowledge of at least one high-level programming language (Python or Go) for more complex automation and building robust tools. Additionally, stay comfortable with scripting languages like Bash or PowerShell for day-to-day SysAdmin/DevOps chores. Having strong expertise in one primary language, plus familiarity with others, will take you a long way on this journey.

1.2 Software Development Lifecycle (SDLC)

• Core concepts: Requirements gathering, development, testing, deployment, maintenance. Having an in-depth understanding and practical experience of the entire software development cycle is crucial—whether or not you can personally execute every phase. Coming from industry, you’re expected to have a solid grasp of each stage in the process.

• Agile and DevOps: Understand the Agile workflow (Scrum/Kanban), continuous integration, continuous deployment, and the feedback loop. As Amazon’s definition of SysDev suggests, you’ll also be expected to maintain operational excellence—troubleshooting issues quickly and putting out fires when needed. This means building robust systems, responding effectively under pressure, and continually improving processes to minimize downtime.

1.3 Cloud Knowledge

The vast majority of Amazon infrastructure is built on AWS, so having strong AWS knowledge is a significant advantage. The more cloud knowledge you have, the better you’ll perform, and the smoother your journey will be—especially for demonstrating expertise in distributed systems. If you prefer Azure or GCP, that’s also beneficial, but AWS is typically recommended for roles at Amazon. Keep in mind that AWS is not strictly required; however, it can streamline your overall preparation for your desired role.

2. AWS Certifications & Advanced Cloud Skills

2.1 AWS Associate-Level Certifications

Completing two AWS Associate-level certifications is a great way to solidify core services knowledge and demonstrate competence. The certification process helps you thoroughly learn AWS’s core services, ensures familiarity with building inside AWS, and can provide greater visibility—both internally and externally—as proof of your strong AWS foundation. If you prefer Azure or any other cloud, that’s still beneficial. Amazon (and most top tech companies) do not look solely for specific technology knowledge, but rather the capacity to adapt to new platforms and continuously learn. A strong base as a builder who can adapt as situations demand is crucial.

Suggested certs:

1. AWS Certified Solutions Architect – Associate

   • Focus: Designing resilient, cost-efficient, fault-tolerant, and scalable systems.

   • Emphasis on architecture best practices and fundamental services (EC2, VPC, S3, RDS, etc.).

2. AWS Certified Developer – Associate (or AWS SysOps Administrator – Associate)

   • Developer Associate: Focus on development, deployment, and debugging in the cloud environment.

   • SysOps Administrator: Focus on deployment, management, and operations in AWS.

3. AWS Certified DevOps Engineer – Professional (Optional)

   • If you’re willing to go the extra mile, this certification can deepen your DevOps expertise and firmly establish your credibility in the field.

2.2 Hands-on Cloud Projects

• Project ideas:

  • Deploy a web application (Python/Node.js) using a CI/CD pipeline in AWS.

  • Automate infrastructure provisioning with AWS CloudFormation or Terraform.

  • Implement monitoring and logging solutions using CloudWatch, CloudTrail, and third-party tools (Datadog, Splunk, etc.).

3. Programming & Automation Skills

3.1 Python as a Primary Language
