Front-End Engineer III, AWS SSO

Amazon • Arlington, VA

6d • $168,100 - $227,400 • Onsite

About The Position

We are creating a brand-new AWS service from the ground up, and the customer experience sits at the very center of it. This is a rare opportunity to join at the earliest stage as the front-end technical leader for a product that meets customers in two places at once: inside the AWS Management Console, plus through a dedicated off-console experience built specifically for this new service. What sets this role apart is that we are building an AI-native application from day one. Agentic integrations and conversational, chat-driven workflows are foundational to the product, not features bolted on after the fact. As the lead Front-End Engineer, you won't simply consume these capabilities; you'll define how we build them, setting the patterns and pushing the boundaries of what a front-end experience can do across AWS products. You'll set the front-end technical direction for the console and off-console experiences, working shoulder-to-shoulder with product managers, UX designers, and engineers to take this service from early definition all the way to launch. Because we're still in the early stages, you'll own the architecture, raise the bar on quality, and mentor other engineers as the team grows. If you're energized by ambiguity, love solving hard problems, and want to help define the next generation of AWS experiences, we'd love to hear from you.

Requirements

• 4+ years of non-internship professional front end, web or mobile software development using JavaScript, HTML and CSS experience
• 5+ years of front-end developer creating prototypes or wire-frames for enterprise web applications or workflows experience
• Experience developing with MVC/MVM frameworks (e.g. React.JS, AngularJS, Vue)

Nice To Haves

• Knowledge of web services technologies such as SOAP, HTTP, WSDL, XSD, and REST
• Experience in a broad range of software design approaches and common UX patterns.

Responsibilities

• Own the front-end architecture for the service across both the AWS Management Console and the new off-console web experience, setting the technical direction and standards others build against — while staying hands-on to design and ship the most complex, high-impact pieces yourself.
• Partner with product managers, UX designers, backend engineers, and science partners to shape product direction, turning ambiguous problems into clear front-end technical strategy and design.
• Define how we build AI-native experiences — establishing the patterns for agentic and conversational workflows (such as streaming responses and real-time updates) and ensuring interfaces are responsive, accessible, and performant at scale.
• Establish and evolve the reusable component libraries, design-system patterns, and front-end architecture that keep the experience cohesive across surfaces, simplifying systems as the product grows.
• Set the bar for end-to-end quality across the team: testing strategy, automated UI testing, CI/CD, and front-end operational excellence.
• Lead code and design reviews for your team, and influence front-end technical decisions with partner teams across AWS.
• Mentor and grow other front-end engineers, helping define the engineering culture and raise the technical capability of the team.

Benefits

• health insurance (medical, dental, vision, prescription, Basic Life & AD&D insurance and option for Supplemental life plans, EAP, Mental Health Support, Medical Advice Line, Flexible Spending Accounts, Adoption and Surrogacy Reimbursement coverage)
• 401(k) matching
• paid time off
• parental leave
• sign-on payments
• restricted stock units (RSUs)
