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

The Security Analytics team builds and manages services that detect security threats using big data collected from millions of sources. We work with service and security teams across AWS to solve security challenges at massive scale. Our services protect the AWS cloud for all customers and preserves our customers’ trust in us.

You’ll work with data scientists, security engineers, and other software development engineers every day. You’ll get to build services that proactively protect every single AWS customer, both internally and externally, from security threats – not many teams can say that!

Work/Life Balance
Our team is focused on balancing life with work. We are flexible when people occasionally need to work from home. We generally keep core in-office hours from 9 am to 5 pm. We are builder-operators of our services at AWS and have a modest on-call rotation where you’ll participate once every 2 – 3 months.

Mentorship & Career Growth
Our team is dedicated to supporting new team members. The team has a mix of experience levels, and we’re building an environment that celebrates knowledge sharing and mentorship. Our senior engineers and managers truly enjoy mentoring junior engineers and engineers from non-traditional backgrounds through one-on-one mentoring and thorough, but kind, code reviews.

We care about your career growth. We assign projects and tasks based on what will help team members develop into a better-rounded engineer and enable them to take on complex tasks in the future.

Inclusive and Diverse Culture
Our team is intentional about attracting, developing, and retaining amazing talent from diverse backgrounds. Yes, we do get to build a cool service, but we also believe a big reason for that is the inclusive and welcoming culture we try to cultivate every day.

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 & inclusive team culture we’ve been building.
