Software Development Engineer II - Hardware Lifecycle Security, AWS Infrastructure Security - H

About AWS Infrastructure Security

AWS Infrastructure Security owns the design, planning, delivery, and operation of all AWS global infrastructure. We support all AWS data centers and all of the servers, storage, networking, power, and cooling equipment that ensure our customers have continual access to the innovation they rely on. We work on the most challenging problems and we’re looking for talented people who want to help.

At Amazon Web Services (AWS), we provide world‑class, flexible, scalable, and secure cloud services. Within AWS, the Infrastructure Security Organization, Hardware Lifecycle Security (Infra Sec‑HLS) team owns the trust stream for network devices, from manufacturing through deployment, ensuring that only verified and trusted devices participate in the AWS network. We build systems that establish device identity, enforce network access decisions, and ensure that nothing communicates on our network without first proving it belongs there.

We work at the intersection of cryptography, hardware security, and large‑scale distributed systems.

The AWS Infra Sec‑HLS team is seeking a Software Development Engineer II to join our Software Development team. You will design, build, and operate software that secures devices across the AWS network. You own your features end‑to‑end and are expected to leave the systems better than you found them. You will mentor other engineers, help new team members get up to speed, and push for better operational practices.

When trade‑offs arise, you work through them with peers and senior engineers.

• Design and deliver software features spanning major portions of the team’s systems, including new development, refactoring, and deprecation.
• Own the full software development lifecycle: scoping, design, implementation, testing, deployment, operations, and documentation.
• Identify root causes of operational issues and resolve them with permanent fixes. Don’t settle for the status quo.
• Provide meaningful code review feedback to peers, including those more senior, and use review as a coaching mechanism.
• Document how the team’s software is constructed, tested, operated, and secured, and train new team members on these points.
• Work with customers, stakeholders, and peers to understand business and customer value and ensure you deliver the right solutions.
• Make priority trade‑offs between new feature development and operational work.
• Resolve disagreements with peers through constructive dialogue.
• Participate in on‑call rotation to support the services owned by the team.

• Experience delivering software end‑to‑end in production.
• Ability to design solutions when the implementation isn’t handed to you.
• Track record of fixing systemic issues, not just symptoms.
• Experience helping other engineers grow.
• Preference for durable solutions over quick fixes.
• Familiarity with distributed systems, security, or infrastructure engineering.
• Judgment on when to push forward alone and when to pull others in.

• 3+ years of non‑internship professional software development experience.
• 2+ years of non‑internship design or architecture (design patterns, reliability and scaling) of new and existing systems experience.
• 1+ years of software development engineer or related occupational experience.
• 1+ years of designing and developing large‑scale, multi‑tiered, multi‑threaded, embedded or distributed software applications, tools, systems, and services using C#, C++, Java, or Perl.
• 1+ years of Object Oriented Design experience.
• Bachelor’s degree or foreign equivalent in Computer Science, Engineering, Mathematics, or a related field.
• Experience programming with at least one software programming language.

• 3+ years of full software development life cycle experience, including coding standards, code reviews, source control management, build processes, testing, and operations.
• Bachelor’s degree in computer science or equivalent.
