Job Description


Job summary
Are you excited at the prospect of keeping millions of customers' data safe? Do you want to help secure web services by implementing cryptography at scale? Security is the #1 concern of customers moving to the cloud and the AWS Cryptography team is dedicated to providing the security features our customers need. We enable customers to confidently move sensitive workloads to the cloud where they can benefit from strong security controls that help meet internal and external compliance requirements.

AWS Key Management Service (KMS) provide encryption and key management services to AWS Services and external customers. We are looking for an experienced software developer with an interest in practical cryptography to join us in building the most secure services in AWS. Our systems protect customer keys and accelerate use of cryptography in all AWS services.

You should have experience designing scalable, customer-centric systems and a passion for simple and elegant software solutions. Along with senior leaders, principal engineers, and security specialists you will discover and solve the new interesting challenges of growing and operating a globally distributed cryptographic security service.

Your responsibilities include:
  • building a massively scalable digital security system that is core to all AWS services.
  • owning the complete software development life cycle; defining, prioritizing, designing, implementing, and testing new features for AWS Cryptography.
  • operating an AWS business with globally distributed servers and customers.
  • working as part of a team to develop solutions for our customers.
  • owning one of the most secure and reliable services in all of AWS.

AWS has the most services and more features within those services, than any other cloud provider-from infrastructure technologies like compute, storage, and databases-to emerging technologies, such as machine learning and artificial intelligence, data lakes and analytics, and Internet of Things. AWS Platform is the glue that holds the AWS ecosystem together. Whether its Identity features such as access management and sign on, cryptography, console, builder & developer tools, and even projects like automating all of our contractual billing systems, AWS Platform is always innovating with the customer in mind. The AWS Platform team sustains over 750 million transactions per second.

We have a formal mentor search application that lets you find a mentor that works best for you based on location, job family, job level etc. Your manager can also help you find a mentor or two, because two is better than one. In addition to formal mentors, we work and train together so that we are always learning from one another, and we celebrate and support the career progression of our team members.

Our team also puts a high value on work-life balance. Striking a healthy balance between your personal and professional life is crucial to your happiness and success here, which is why we aren't focused on how many hours you spend at work or online. Instead, we're happy to offer a flexible schedule so you can have a more productive and well-balanced life-both in and outside of work.

Here at AWS, we embrace our differences. We are committed to furthering our culture of inclusion. We have ten employee-led affinity groups, reaching 40,000 employees in over 190 chapters globally. We have innovative benefit offerings, and we host annual and ongoing learning experiences, including our Conversations on Race and Ethnicity (CORE) and AmazeCon (gender diversity) conferences. Amazon's culture of inclusion is reinforced within our 14 Leadership Principles, which remind team members to seek diverse perspectives, learn and be curious, and earn trust.
