<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>
BuyWander is an Equal Opportunity Employer. We make employment decisions based on qualifications, skills, merit, and business needs. We believe a range of skills, perspectives, and experiences strengthens our team and supports better outcomes for our employees and customers.</p></div>

Privacy Statement</i></b></p>
<p><i>
All member records are protected according to our</i><i> </i><i>Privacy Policy</i><i>. Further, while employees of Headspace (formerly Ginger) cannot access Headspace products/services, they will be offered benefits according to the company's benefit plan. To ensure we are adhering to best practice and ethical guidelines in the field of mental health, we take care to avoid dual relationships. A dual relationship occurs when a mental health care provider has a second, significantly different relationship with their client in addition to the traditional client-therapist relationship&mdash;including, for example, a managerial relationship.
</i></p><p><i>As such, Headspace requests that individuals who have received coaching or clinical services at Headspace wait until their care with Headspace is complete before applying for a position. If someone with a Headspace account is hired for a position, please note their account will be deactivated and they will not be able to use Headspace services for the duration of their employment.</i></p>
<p><i>
Further, if Headspace cannot find a role that fails to resolve an ethical issue associated with a dual relationship, Headspace may need to take steps to ensure ethical obligations are being adhered to, including a delayed start date or a potential leave of absence. Such steps would be taken to protect both the former member, as well as any relevant individuals from their care team, from impairment, risk of exploitation, or harm.</i></p>
