Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Senior Software Engineer, Auctions - **Company:** BSL - Applied Laser Technologies LLC - **Location:** San Francisco, CA, United States (Remote available) - **Experience:** Expert - **Salary:** $200,000.0 - $220,000.0 - **Contract:** Permanent contract - **Skills:** Artificial Intelligence, Amazon Web Services, Computer Vision, Cloud Computing, Python (Programming Language), PostgreSQL, Recommender Systems, TypeScript, ReactJS, Large Language Models, Front End Software Development, Google Meet, Crud - **Published:** September 5, 2026 - **Apply:** https://arc.dev/remote-jobs/j/redirect/phpyd65o25 ## About the Role * 5+ years building and scaling complex applications - Python, Postgres, AWS or comparable cloud infrastructure. * Modern frontend mastery. Deep experience with React, TypeScript, and building high-performance real-time UIs. Real-time is the operative word: this is not a CRUD screen. * Reliability under pressure. A track record of building systems that stay up when the stakes and the traffic are highest. You've been paged during the worst possible ten minutes. * AI pragmatism. You've taken LLMs or computer vision models and turned them into practical, user-facing features that solved a real business problem. Not a demo. * Product instincts. You don't build what's on the ticket. You understand the collector mindset and build things that delight them - and you can explain the why behind past work before you explain the how. * High agency. You thrive where you're expected to find the highest-leverage work and go execute it without a hand-holding manual. Bonus: experience with personalization engines, recommendation systems, or AI/ML integrations. Startup experience. You collect, or you have a view on where this market is going. ## Description We'll be specific so you can prepare. Before any of it: download the app, put a card up, make a bid, and try our selling feature. Every round assumes you've used the product, and we expect your point of view to sharpen as you go. For this role, actually sit through the end of a live auction. Notice what the UI tells you and what it doesn't. * Recruiter screen - 25 minutes, Google Meet. Come ready to talk about the metric you own today and how you're performing against it, why Alt specifically, and how you're actually using AI. We'll align on comp and answer your questions. * Hiring manager - 45 minutes, Google Meet. Be ready to go deep on a project you owned end to end - starting with the problem it existed to solve, then the design, then what was yours versus the team's, then the outcome. * Technical screen - 60 minutes. A hands-on working session on a concurrency problem close to what this role actually does. Think out loud. * System design - 60 minutes. Design the bidding path under real load. We'll push back on at least one of your choices on purpose - how you take that matters as much as the design. * Why Alt,- 30 minutes. Exactly what it says. Come with something specific. * Leore, our founder and CEO - 30 minutes Everyone who joins Alt meets Leore. Come with a point of view on where you'd take auctions first. * Reference checks - 15 minutes with a former manager(s) ## Related Videos - [ Your Code Is the Sales Team Now](https://www.wearedevelopers.com/videos/100327-your-code-is-the-sales-team-now) - [Rest API Antipatterns](https://www.wearedevelopers.com/videos/100208-rest-api-antipatterns) - [Watch Tests Go Brrrr! : Getting Started with Cypress in ReactJS](https://www.wearedevelopers.com/videos/282-watch-tests-go-brrrr-getting-started-with-cypress-in-reactjs) - [Optimizing Discovery: PostgreSQL's Role in Transforming GetYourGuide's Search](https://www.wearedevelopers.com/videos/1647-optimizing-discovery-postgresql-s-role-in-transforming-getyourguide-s-search) - [Meet Your New BFF: Backend to Frontend without the Duct Tape](https://www.wearedevelopers.com/videos/682-meet-your-new-bff-backend-to-frontend-without-the-duct-tape) - [Discover the open source trio you didn’t expect: .NET and PostgreSQL on Linux](https://www.wearedevelopers.com/videos/2042-discover-the-open-source-trio-you-didn-t-expect-net-and-postgresql-on-linux) ## Related Articles - [Dev Digest 137 - AI'm not sure about this](https://www.wearedevelopers.com/magazine/485-dev-digest-137-ai-m-not-sure-about-this) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [Dev Digest 120 - Apple and peers](https://www.wearedevelopers.com/magazine/455-dev-digest-120-apple-and-peers) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Dev Digest 132 - Binging WADFlix?](https://www.wearedevelopers.com/magazine/473-dev-digest-132-binging-wadflix)
