Software Engineer II, Backend

Amazon.com

<div><h2 class="jobSectionHeader"><b>DESCRIPTION</b></h2><div>
Do you want to build software that changes how physical things get made? Amazon Manufacturing Services (AMS) runs 135+ machines producing custom parts for over 100 Amazon organizations. We are building the next generation of services and applications that digitize shop floor operations, integrate with enterprise manufacturing platforms, and lay the groundwork for intelligent production scheduling. You will work across the full stack &mdash; React applications for operators and planners, event-driven backend services processing manufacturing data in real time, and integration bridges connecting AMS to enterprise ERP, PLM, and MES systems. The team is small, the technical surface is broad, and the users are in the building.<br>
<br>
Key job responsibilities<br>
<ul><li>Design, build, and operate services on AWS Lambda, DynamoDB, S3, SNS, SQS, and Step Functions using event-sourced, domain-driven architecture patterns</li><li>Build React web applications using the Cloudscape Design System for manufacturing operators, planners, and engineers</li><li>Integrate AMS services with enterprise platforms through event-based and API-based integration patterns</li><li>Design and implement API models, CDK infrastructure, and CI/CD pipelines for new services</li><li>Collaborate with senior engineers on system design, code reviews, and architecture decisions</li></ul><br>
A day in the life<br>
Your day starts with a standup alongside SDEs, data engineers, and manufacturing stakeholders. You pick up where you left off on a React component that displays real-time resource status for shop floor planners. After lunch, you shift to a backend service, designing a DynamoDB schema for part versioning. A code review comes in from a senior engineer working on an enterprise integration bridge, and you spend time understanding how AMS connects to external manufacturing platforms.
<br>
<br>
Some weeks lean more frontend &mdash; building interactive data visualizations or responsive layouts for shop floor devices. Other weeks lean more backend &mdash; implementing event-sourced entity patterns or integrating with third-party APIs. The mix depends on the sprint and your strengths.</div><h2 class="jobSectionHeader"><b>

<h1 class="jobSectionHeader"><b>Senior Software Engineer (Search &amp; Personalization)</b></h1><p><b>
Location:</b> Seattle, WA <b>Type:</b> Full-Time | Engineering</p><h3 class="jobSectionHeader"><b>
ABOUT BUYWANDER</b></h3><p>
BuyWander is rebuilding the $850B retail returns industry. We take chaotic truckloads of returned goods and transform them into a fast, fun, treasure-hunt shopping experience powered by AI, real-time auctions, and local pickup.</p><p>
We&rsquo;re not just building a marketplace. We&rsquo;re building a daily habit.</p><h3 class="jobSectionHeader"><b><br>
THE ROLE</b></h3><p>
We are looking for a highly product-minded <b>Senior Software Engineer</b> to own our Search and Personalization experience.</p><p>
With the rapid advancement of AI coding agents (like Claude Code and Cursor), the way we build across the stack has completely changed. We aren't hiring you to spend your days writing boilerplate UI components. We are hiring you for your architectural brain and product sense.</p><p>
Your mandate is to build the discovery engine that keeps our users addicted to the &quot;treasure hunt.&quot; You will partner with our Data &amp; AI team to take raw recommendation models and turn them into lightning-fast, highly personalized consumer experiences.</p><h3 class="jobSectionHeader"><b><br>
WHAT YOU&rsquo;LL OWN</b></h3><p><b>
1. The Discovery &amp; Personalization Engine</b></p><ul><li>
Design and implement the architecture for our &quot;For You&quot; feeds.</li><li>
Blend rules-based logic with ML-driven recommendations to ensure the right weird, unique, or high-value item hits the exact right bidder at the right time.</li></ul><p><b>
2. Search Optimization</b></p><ul><li>
Own our core search infrastructure (Elastic Cloud / Pinecone).</li><li>
Implement hybrid search (keyword + vector), tune ranking weights, and build typo-tolerance and synonym matching so our buyers always find what they are looking for.</li></ul><p><b>
3. Measuring Success &amp; Experimentation</b></p><ul><li>
You don't just ship features; you measure them. You will design the A/B testing framework for our search ranking changes.</li><li>
Track click-through rates (CTR), bid velocity, and conversion metrics to definitively prove your search tweaks are making the company money.</li></ul><p><b>
4. AI-Assisted Product Development</b></p><ul><li>
Use modern AI coding tools to rapidly wire your backend search APIs into our Vue/Nuxt frontend.</li><li>
Focus your deep thinking on system design, database queries, and user flows, while leveraging AI agents to accelerate UI execution.</li></ul><h3 class="jobSectionHeader"><b>
WHY THIS ROLE IS DIFFERENT</b></h3><p>
At most companies, you are handed a Jira ticket and told exactly what to build. Here, you are handed a business problem: <i>&quot;Our bidders are having trouble finding niche electronics in our chaotic inventory&mdash;fix it.&quot;</i></p><p>
You will have the autonomy to design the search logic, test the algorithms, and ship the product experience that solves that problem. If you love building systems that directly drive user addiction and marketplace revenue, let's talk.</p><p><b>
Benefits</b></p><ul><li>
Competitive Salary and Performance-based Bonuses
</li><li>Meaningful equity in a company attacking a massive market, for a brand that can become nationally recognized</li><li>
Health, Vision &amp; Dental Insurance
</li><li>Unlimited PTO
</li><li>Annual Company Offsites
</li><li>401K</li></ul>
Requirements:<h3 class="jobSectionHeader"><br>
</h3><h3 class="jobSectionHeader"><b>
WHAT YOU BRING</b></h3><ul><li><b>
The Tech Stack:</b> Deep backend proficiency (we use C#/Python/FastAPI) and a solid understanding of modern frontend frameworks (we use Vue/Nuxt/Vercel).</li><li><b>
Search Expertise:</b> Proven experience tuning search engines (Elasticsearch, Algolia, or OpenSearch) and familiarity with modern Vector databases (Pinecone).</li><li><b>
Product Sense:</b> You think in terms of user psychology and metrics. You understand concepts like collaborative filtering, session-based recommendations, and ranking algorithms.</li><li><b>
The Modern Workflow:</b> You are highly proficient in using AI developer tools (Copilot, Cursor, Claude) to multiply your output.</li></ul><p>
