Senior Software Development Engineer, AWS Elastic Load Balancing - FLUX

Job ID: 1343709 | Amazon Dev Center U.S., Inc.


Do you want to help lead the cloud revolution and build software that thrives at immense scale?

AWS Elastic Load Balancing enables customers to build large scale highly available services. ELB automatically distributes incoming application traffic across multiple targets, such as Amazon EC2 instances, containers, IP addresses, and Lambda functions. ELB provides the entry point for building hyper scale, fault tolerant applications. While ELB has seen tremendous growth since launch we are still in the early stages of realizing its full potential.

As a Senior Software Development Engineer for the ELB Fleet Update Experience (FLUX) team, you will join a new team of deeply technical engineers relentless in their mission to design and build systems to rapidly and safely deploy changes to a massive fleet of load balancers. You are customer obsessed and thrive in the world of deployment at scale. In this role, you will provide technical leadership, solve complex software problems, and make impactful trade-offs between short-term and long-term results. You’ll think in terms of architecture, not just code, and will help elevate our ability to deploy and operate high availability systems worldwide.

A successful candidate is comfortable in a leadership role and seeks to mentor and grow less experienced engineers on the team. You understand customer obsession and live and breathe operational excellence. You know when to partner with and influence other teams to deliver results.

Inclusive Team Culture
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 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.

Work/Life Balance
Our team puts a high value on work-life balance. It isn’t about how many hours you spend at home or at work; it’s about the flow you establish that brings energy to both parts of your life. We believe striking the right balance between your personal and professional life is critical to life-long happiness and fulfillment. We offer flexibility in working hours and encourage you to find your own balance between your work and personal lives.

Mentorship & Career Growth
Our team is dedicated to supporting new members. We have a broad mix of experience levels and tenures, and we’re building an environment that celebrates knowledge sharing and mentorship. Our senior members enjoy one-on-one mentoring and thorough, but kind, code reviews. We care about your career growth and strive to assign projects based on what will help each team member develop into a better-rounded engineer and enable them to take on more complex tasks in the future
