Amazon is an American technology and retail conglomerate founded by Jeff Bezos in 1994 as an online bookstore and headquartered in Seattle, Washington. It operates the world's largest online marketplace together with a global logistics network, physical grocery stores and a third-party seller platform that accounts for most units sold. Amazon Web Services, launched in 2006, is the leading public cloud provider and generates the majority of the group's operating profit, while advertising, Prime Video, Alexa devices and Kuiper satellite broadband round out the business.

Come and build innovative services that protect our cloud from advanced security threats!

As a Software Development Engineer on our team, you’ll help build and manage services that detect and automate the mitigation of cybersecurity threats across Amazon’s infrastructure, including advanced persistent threats. You’ll work with security engineers, data scientists, and other software development engineers across multiple teams to develop innovative security solutions at a massive scale. Our services protect the AWS cloud for all customers and help preserve our customers’ trust in us. You’ll get to use the full power and breadth of AWS technologies to build services that proactively protect every single AWS customer, both internally and externally, from security threats - not many teams can say that!

We’re looking for a new teammate who is enthusiastic, empathetic, curious, motivated, reliable, and able to work effectively with a diverse team of peers. We want someone who will help us amplify the positive and inclusive team culture we’ve been building.

Key job responsibilities

As a Software Development Engineer, you will leverage Amazon technology (Lambda, Kinesis, DynamoDB, etc.) to solve AWS Security problems at staggering scale. You will raise the bar on our software architecture and development practices. You will share ownership of our operational excellence, ensuring our system is properly tuned and has appropriate alarms for warning or error conditions. You will help drive our working backwards processes, inventing and simplifying on behalf of our customers. You will build security detections that identify specific security issues and automatically help customers reduce their risk through network and security controls.

On-Call Responsibility

This position involves on-call responsibilities, typically for one week every few weeks. We don’t like getting paged in the middle of the night or on the weekend, so we work to ensure that our systems are fault tolerant. When we do get paged, we work together to resolve the root cause so that we don’t get paged for the same issue twice.

A day in the life

- Collaborate with data scientists and security engineers to build automated security detection and mitigation workflows

- Design scalable architectures for low-latency, big data processing

- Improve the observability, performance, and efficiency of our existing systems

- Raise the bar for testing, repeatability, automation, and operational excellence

- Mentor and develop teammates, both technically and professionally

- Seek out, develop, and advocate for new technologies
