- Describes themselves as back-end-strong but stack-agnostic, and is comfortable working across the stack—including on client platforms or shared protocols—when the product needs it.
- Has hands-on experience building or integrating LLM-powered or agentic features (well beyond a one-off API call), with a real feel for the cost, latency, streaming, and quality/false-positive trade-offs that come with AI products.
- Is proficient in one or more of Java, Go, or Python.
- Has experience with AWS or GCP (other cloud offerings such as Azure are a plus).
- Displays excellent software engineering fundamentals, including knowledge of algorithms and data structures.
- Has experience building, deploying, and debugging production systems at scale.
- Demonstrates perseverance when faced with tough technical issues.
- Cares about the end-user experience and strives to ensure high quality.
- Collaborates effectively with cross-functional partners—product managers, designers, linguists, and engineers on other platforms—rather than shipping in isolation.
- Has a demonstrated ability to work independently with minimal guidance, proactively manages tasks and priorities across multiple projects, analyzes and executes work efficiently, and thrives in fast-paced, results-driven environments.
