You use them to move quickly and take responsibility for understanding, reviewing, and testing what you ship. * Excited by marketplace dynamics like matching, routing, pricing, and network effects. * Comfortable working across the whole product, talking directly with users, and figuring out what to do without a detailed specification. You may have done this as a founder, an early engineer, or in another role with broad ownership. ## Description We're a small team, and everyone works across the product. You might improve expert onboarding, debug a payout, build a recruitment agent, or extend a customer integration in the same week. You'll work directly with the CTO and operations team to identify what needs attention and take it through to production. Within your first month, we expect you to understand the product end to end and independently investigate, build, and ship improvements wherever they're needed. You will * Own and scale the recruitment engine, the algorithm that finds any niche audience in the world through network traversal, targeted ads, referrals, automated outbound, and anything else you can come up with. * Build and extend the Terac API that research tooling companies and AI data companies integrate against. * Build and improve agents that screen experts through voice and chat, assess their work, identify fraud, and help our team run projects. Evaluate how they perform with real users and make their actions reliable and reviewable. * Build marketplace systems for opportunity matching, pricing, feasibility estimation, and repeat engagement. Use what we learn from completed projects to improve who we recruit and how we match them. * Design and build the expert experience, including onboarding, project instructions, ongoing work, and payouts. Work with experts and our operations team to understand where people get stuck and fix it. * Own the behavior of what you ship in production. Investigate failures across the product, background jobs, and external services, and improve the systems that handle people's work, data, and money. * Work directly with the CTO to shape the architecture behind autonomous agents, real-time voice, and a global expert marketplace. Our core stack includes TypeScript, Next.js, Python, Postgres, and AWS. ## Related Videos - [Under the Hood of Building on Lovable](https://www.wearedevelopers.com/videos/100032-under-the-hood-of-building-on-lovable) - [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) - [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) - [GraphQL + Apollo + Next.js: A Lovely Trio](https://www.wearedevelopers.com/videos/311-graphql-apollo-next-js-a-lovely-trio) - [It's a Great Time to be a Builder: Leveraging AI for Good](https://www.wearedevelopers.com/videos/100042-it-s-a-great-time-to-be-a-builder-leveraging-ai-for-good) - [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 - [The Best X (Twitter) Accounts for Developers](https://www.wearedevelopers.com/magazine/294-the-best-x-twitter-accounts-for-developers) - [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 137 - AI'm not sure about this](https://www.wearedevelopers.com/magazine/485-dev-digest-137-ai-m-not-sure-about-this) - [Dev Digest 132 - Binging WADFlix?](https://www.wearedevelopers.com/magazine/473-dev-digest-132-binging-wadflix) - [Dev Digest 121 - AI goes offline](https://www.wearedevelopers.com/magazine/456-dev-digest-121-ai-goes-offline)
