Principal Software Engineer (polyglot) - Brazil (remote) Get AI-powered advice on this job and more exclusive features. About Dscout At Dscout, we’re building the most flexible and powerful UX research platform on the market—trusted by the world’s top brands in finance (JP Morgan Chase), healthcare (Aya, Headspace), consumer goods (Keen, Verizon), and tech (FAANG, Spotify, AirBnB). Our tools help teams deeply understand the humans behind their products, so they can build better ones. We’re already recognized as a leader in the UX research space. Now, we’re going even further. We’re transforming our platform and internal development lifecycle to be AI-first—rethinking how we collect, analyze, and act on rich media data (think: video, audio, open text) at scale. Engineers at Dscout aren’t just maintaining code—they’re building what’s next: whole new products and infrastructure designed from the ground up with GenAI at the core. If you’re curious, collaborative, and excited about using AI to solve meaningful, complex problems—we’d love to meet you. Our Platform Our frontend is built with React. Our backend uses Elixir and Python. GenAI has significantly impacted our system architecture, requiring us to adapt and evolve. Our department is in the midst of a shift from existing products augmented with AI to AI-first products. Existing Production Products Our frontend is in TypeScript & React. And our backend is in Elixir with Phoenix, Ecto, Absinthe, and Oban. The two talk to each other through GraphQL and live in one monorepo. We use Postgres for all of our DB needs and are hosted in AWS. We also have a native iOS and Android app that use Swift and Kotlin. We also make heavy use of WebRTC and WebSockets. GenAI features are frequent in our existing products, ranging from summarization, categorization, and guardrails against inappropriate data collection. These are built in our new Python stack and accessed via various APIs from Elixir. To share a sense of our scale, we have about 11 years of video stored on our platform. All of which we process on our own. Emerging AI-first Products Until this moment, the Elixir ecosystem provided us with everything we needed. To meet the speed and demand of GenAI development we have adopted the state-of-the-art tools & frameworks in the Python ecosystem, specifically the Lang family of frameworks. Modular architecture forms the building blocks of our agentic, AI-first applications that will eventually replace our existing products. You Are… A polyglot Principal Software Engineer who will help us build and scale our new, AI-first and agentic products.
