What we expect from you:

• Strong experience with React and TypeScript, including building production-grade web applications.
• Solid backend development experience in any modern language (Rust experience is a plus; willingness to dive into Rust is essential).
• Deep understanding of data architecture and modeling, especially around unstructured → structured data transformation.
• Experience integrating external APIs, handling complex data ingestion, and dealing with messy real-world inputs.
• Ability to work independently in a fast-paced startup environment as the first engineering hire.
• Familiarity with Agile workflows (daily standups, iterations, async communication).
• Comfortable with remote collaboration, including Slack, video calls, and async updates.
• English proficiency at Upper-Intermediate level for effective team communication.
• Bonus: experience with LLM APIs, data extraction pipelines, forecasting systems, or operational automation workflows.
