senior front end engineer

Amazon Web Services

<div><h2 class="jobSectionHeader">DESCRIPTION</h2>
AI is not just changing what software can do; it is fundamentally changing how software is built. We are building the next generation of developer tooling: an AI-native tool that redefines the software engineering workflow from the ground up. Our product sits at the center of a developer's day, and we are obsessed with making that experience fast, delightful, and powerful.
 
 
We are looking for engineers who are passionate about building exceptional user-facing client software. If you care deeply about UI responsiveness, interaction design, and the quality of tools engineers use to build software, this team is for you.
 
 
You will work alongside exceptional senior engineering talent solving hard problems at the frontier of AI and developer tooling. You'll have opportunities to work with and learn from best-in-industry senior engineering talent. In addition to the technical challenges provided by the innovative use cases that we are working on, you will also learn how to build a product that meets AWS's high bar for availability, scalability, and security.
 
 
You'll have a direct line to our customers' experience and a direct means of improving it. On a daily basis, you'll work with teammates to review each other's code, mentor and be mentored. You'll have an opportunity to lead from day one, from leading projects, to driving technical processes, to teaching and learning from your teammates. You will have real ownership, from setting technical direction to shipping features that developers notice and love.
 
 
Key job responsibilities 
Own the end-to-end delivery of high-impact, user-facing features built with TypeScript and React, from writing the technical spec to shipping to customers
 
 
Drive technical direction for client-side architecture and establish patterns that raise the bar for quality across the team
 
 
Work closely with designers and product managers to ensure every feature meets a high bar for developer UX and interaction quality
 
 
Build and use AI agents to accelerate your own development workflow
 
 
Exercise high judgment about when to guide, override, or take control from AI agents &mdash; knowing when to trust automation and when the situation demands your direct involvement
 
 
Mentor and guide less tenured engineers, helping them navigate technical challenges, grow their skills, and advance their careers
 
 
Work with Product and Design to deeply understand customer workflows and build backward from their needs, maintaining Amazon's commitment to starting from the customer
 
 
A day in the life 
Use AI agents to write code and move fast, and direct code review agents to help the team catch issues before they ship
 
 
Conduct design and UX reviews with your PM and designer to ensure every feature meets a high bar for developer experience
 
 
Take full ownership of a feature set actively used by customers, deliver high-impact features end to end, from the initial spec to the moment they ship, and take pride in building software that genuinely delights the developers who use it every day.
 
 
Participate in the team's Weekly Operations Review and understand the key metrics that drive our product
 
 
Work with your manager to understand how to grow your career at AWS and how to build a career growth plan
 
 
Become an active participant in all stages of our software development cycle, including roadmap planning and product review meetings
 
 
Work with other engineers to improve our operational effectiveness by designing new systems and making our current ones more effective
 
 
Help onboard new engineers and guide them in their first weeks at AWS
 
 
Hold a high bar for user experience in every feature you ship: obsess over every interaction, every millisecond of latency, and choose the path that serves users best even when it is harder to build
 
 
Continuously measure, monitor, and improve client-side performance across all supported operating systems
 
 
About the team 
We are a team of engineers who believe the way software is built is about to change permanently, and we are the ones defining that change. We are building an AI-native developer environment that sits at the intersection of cutting-edge AI and the craft of software engineering. Our team is obsessed with the developer experience: we care about performance, interaction design, and the small details that make a tool feel fast and effortless. We dogfood our own product every day, which means every improvement we ship makes us better engineers too. If you want to build the tools that shape how the next generation of software is written, this is the team for you.
 
 
Agentic AI drives innovation at the forefront of artificial intelligence, enabling customers to transform their businesses through cutting-edge AI solutions. We build and deliver the foundational AI services that power the future of cloud computing, helping organizations harness the potential of AI to solve their most complex challenges. Join our dynamic team of AI/ML practitioners, applied scientists, software engineers, and solution architects who work backwards from customer needs to create groundbreaking technologies. If you're passionate about shaping the future of AI while making a meaningful impact for customers worldwide, we want to hear from you.

Frontend Software Engineer - Remote

Mill

<div><div>Mill is a waste prevention technology company reimagining what it means to eliminate waste, starting with food. We build smart systems and infrastructure for homes, businesses, and municipalities that transform food scraps from landfill-bound waste into valuable resources, including chicken feed. Tens of thousands of Mill's residential food recyclers are already helping households divert millions of pounds of food scraps every year, paving the way for our upcoming launch of Mill Commercial&mdash;the industry's first end-to-end solution for managing, understanding, and preventing food waste in commercial environments (e.g. grocery, restaurants, food services). At Mill, we are passionate about building easy-to-use, beautifully designed technologies that keep food in the food system and out of landfills.</div>
We are seeking a highly skilled Senior Full Stack Engineer to join our engineering team. This is an individual contributor technical leadership role reporting to the Director of Software Engineering. You will drive the technical direction of your project area and write high-quality code across the stack, while mentoring engineers around you.

We've moved away from a frontend/backend split at Mill: every engineer here works full stack, typically leaning toward one side based on strength and interest, and teams are organized around projects rather than layers of the stack. You'll likely anchor on a given project for a sustained stretch &mdash; enough to build real depth and avoid constant context-switching &mdash; with real opportunities to rotate onto new projects and parts of the codebase over time.

AI-assisted development is core to how we build software, not a peripheral tool. We expect fluency with tools like Claude Code as part of your daily workflow, and as a senior level engineer, a role in raising the bar for how the team uses them.
<h2 class="jobSectionHeader">
Key Responsibilities</h2>

Technical Leadership
<div>
<ul><li>Lead the technical design and execution of full-stack web applications, ensuring alignment with business objectives and technical standards</li></ul>
<ul><li>Design and implement scalable, secure, and efficient full-stack solutions</li></ul>
<ul><li>Own estimates and technical delivery plans and surface risks early</li></ul>
</div>
Development and Implementation
<div>
<ul><li>Craft elegant, documented, and sustainable code spanning our full web stack, remaining ready to provide support for our native mobile environment when required</li></ul>
<ul><li>Develop and optimize API and user interfaces</li></ul>
<ul><li>Use AI-assisted development tools fluently as a standard part of how you write, review, and ship code</li></ul>
</div>
Team Collaboration
<div>
<ul><li>Mentor junior engineers, fostering a culture of continuous learning and improvement.</li></ul>
<ul><li>Conduct code reviews and provide constructive feedback to maintain high coding standards.</li></ul>
<ul><li>Communicate technical constraints and tradeoffs clearly to your project's product manager.</li></ul>
</div>
Quality Assurance
<div>
<ul><li>Champion best practices in testing, CI/CD, and deployment</li></ul>
<ul><li>Troubleshoot and resolve technical issues, ensuring minimal downtime and disruption</li></ul>
<ul><li>Monitor and optimize application performance</li></ul>
</div><h2 class="jobSectionHeader">Required Qualifications</h2>
<ul><li>5+ years of professional experience in software development with a focus on full-stack development</li>
<li>Deep experience with modern frontend frameworks (e.g. React, Vue, Angular, or SvelteKit) &mdash; we use SvelteKit at Mill but recognize that strong React/Vue/Angular experience is highly transferable, especially with AI-assisted tooling, so prior SvelteKit experience is preferred but not required</li>
<li>Strong backend experience with TypeScript/Node.js; comfort with serverless architectures (e.g. AWS Lambda)</li>
<li>Solid understanding of SQL and NoSQL database systems</li>
<li>Experience with cloud platforms (we run AWS) and modern deployment workflows</li>
<li>Fluency with AI-assisted development workflows (e.g. Claude Code, Copilot) as a genuine part of your day-to-day practice &mdash; not occasional or exploratory use</li>
<li>Strong software architecture fundamentals (e.g. microservices, serverless)</li>
<li>Excellent problem-solving and debugging skills</li>
</ul><h2 class="jobSectionHeader">Preferred Qualifications</h2>
<ul><li>Experience with our specific stack: SvelteKit (web, deployed on Vercel), React Native (mobile), AWS Lambda with CDK (TypeScript) and Middy</li>
<li>Familiarity with DevOps practices and infrastructure as code (e.g. Terraform, CDK)</li>
<li>Strong understanding of security best practices in web development</li>
<li>Prior experience working at a hardware company, particularly collaborating with firmware teams &mdash; we build physical devices, not just software, and comfort working alongside hardware/firmware engineers is a plus</li>
</ul><h2 class="jobSectionHeader">Key Attributes</h2>
<ul><li>Strong communication and interpersonal skills &mdash; especially the ability to partner closely with product without owning the roadmap</li>
<li>Comfortable holding technical ownership of a project over a sustained period, while staying energized by the opportunity to rotate onto new problems periodically</li>
<li>Proactive, self-driven, and eager to take ownership of projects</li>
<li>Passion for mentoring and developing engineering talent</li>
</ul>
The estimated base salary range for this position is $185k to $210k, which does not include the value of benefits or a potential equity grant. A wide range of factors are considered in making compensation decisions, including but not limited to skill sets, market conditions, experience and training, licensure and certifications, and business and organizational needs.</div>
