We're building a daily habit. And the marketplace - the auctions, the app, the search, the moment a customer discovers something they didn't know they wanted - is where that habit is won or lost.\nThat's what you'd own.\nTHE ROLE\nWe're hiring a Software Development Lead - the most senior hands-on engineer on our customer-facing product.\nThis is an IC+ role. You'll write code, set technical direction, and own the systems that power the buyer experience end to end: auctions, website/app, notifications, search, and personalization. You'll be the person who makes the marketplace fast, reliable, and addictive - and who raises the technical bar for everyone building alongside you.\nYou won't inherit a finished product. You'll shape it. We have a foundation and momentum; we need a builder who can take the marketplace to the next level.\nWe're looking for someone who is:\nA hands-on builder first - you ship, and your code sets the standard\nProduct-minded - you care why a feature exists, not just how to build it\nObsessed with the customer experience - speed, polish, and delight matter to you\nAI-forward - you use modern tools to move faster and build smarter\nWHAT YOU'LL OWN\nReal-Time Auctions\nOwn the auction engine that powers live bidding - real-time, accurate, and rock-solid under load\nHandle the hard problems: concurrency, bid integrity, race conditions, and the spikes that come with a live marketplace\nPartner with Data on auction design, demand signals, and pricing\nWebsite & App\nLead development of the buyer-facing web and mobile experience (Vue/Nuxt front end, Python/C# services)\nMake it fast, intuitive, and fun - the treasure hunt should feel like a treasure hunt\nOwn performance, reliability, and the release process for the product customers touch every day\nSearch & Discovery\nBuild search that helps people find - and stumble onto - items they'll love, across a constantly changing, one-of-a-kind inventory\nTune relevance, ranking, and browse for a catalog where no two items are alike\nPersonalization\nTurn browse ? bid ? win ? pickup behavior into a personalized experience\nPartner with Data to surface the right items to the right customer at the right moment\nNotifications & Engagement\nOwn the notification systems (push, email, in-app) that bring customers back - outbid alerts, auction endings, new drops\nBuild engagement loops that drive the daily habit without becoming noise\nTechnical Leadership (hands-on)\nSet the technical direction, architecture, and quality bar for marketplace engineering\nMentor other engineers through code review, design, and example\nMake pragmatic build-vs-buy-vs-integrate calls and own the outcomes\nPartner closely with Product, Data, and Warehouse/Ops engineering to keep the full experience aligned\nRequirements\nWHAT YOU BRING\n6+ years building and shipping consumer-facing web/mobile products at scale\nDeep hands-on strength across the stack - comfortable owning both front end and backend services\nExperience with real-time systems - live auctions, bidding, feeds, or similar high-concurrency products\nExperience with marketplaces, auctions, or high-concurrency consumer apps\nSearch / relevance or recommendation / personalization systems experience\nNotification and engagement / lifecycle systems at scale\nA track record of leading technically as the senior builder - through code and architecture, not just meetings\nStrong product instincts and an eye for customer experience, performance, and polish\nA strong point of view on how AI is reshaping product engineering\nAbility to move fast in a 0?1 / high-growth environment with imperfect requirements\nOur stack: C#/Python, FastAPI, Vue/Nuxt, PostgreSQL, real-time event streams. You don't need every one, but you should be dangerous across most of it.\nWHY THIS ROLE IS DIFFERENT\nMost marketplace engineering roles are maintenance: keep the site up, ship the next ticket.\nThis one is different. Our inventory is chaotic and one-of-a-kind, our auctions are live, and our customers come for the hunt. You'll own the systems that turn that into a daily habit - and you'll have the autonomy and equity of someone shaping a category-defining product from the ground up.\nYou'll work directly with leadership to define how BuyWander wins on the customer side.\nBENEFITS\nCompetitive salary + performance bonuses\nMeaningful equity in a category-defining company\nHealth, Vision & Dental Insurance\nUnlimited PTO\nAnnual Company Offsites\n401K\nBuyWander is an Equal Opportunity Employer.","description_format":"text","description_chars":5008,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["401k plan","Dental insurance","Equity","Unlimited PTO"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Marketplaces","Commerce","Auctions"],"lifecycle":[{"event":"open","at":"2026-09-26T17:44:03Z"}],"visa":[],"liveness":{"score":10,"band":"cold","label":"Long shot","p_open":1,"p_active":0.339,"p_room":0.28,"age_days":94,"expected_fill_days":35,"reasons":["conf:6","win:tail","crowd:"],"computed_at":"2026-10-21T05:46:15Z"},"pay":null,"html_url":"https://alion.io/job/buywander-software-development-lead-marketplace","json_url":"https://alion.io/job/buywander-software-development-lead-marketplace.json","meta":{"generated_at":"2026-10-21T06:55:23Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":9798,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-22T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":3792376},"rest":"https://alion.io/mcp/rest/get_company?id=3792376"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fbuywander-software-development-lead-marketplace"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fbuywander-software-development-lead-marketplace"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fbuywander-software-development-lead-marketplace"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/buywander-software-development-lead-marketplace\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fbuywander-software-development-lead-marketplace"}]}
