Key Responsibilities

- Feature Ownership: Design, build, and maintain scalable features across our backend services and frontend applications.

- Performance Optimization: Write highly efficient code to minimize latency overhead in our prompt routing pipeline.

- Database Management: Schema design, query optimization, and data modeling across relational and non-relational data stores.

- Infrastructure Support: Deploy, monitor, and manage cloud resources to ensure high availability of our services.

- Quality & Testing: Maintain a rigorous testing culture by writing comprehensive unit, integration, and end-to-end tests.

Technical Requirements

Backend & Core Logic

- 2+ years of professional software engineering experience in a production environment.

- Strong proficiency in either Go (Golang) or Python for building backend services.

- Solid understanding of asynchronous programming, concurrency patterns and building RESTful or gRPC APIs.

Frontend & Logic Layer

- Strong experience with TypeScript and Node.js.

- Proficiency in modern frontend frameworks (e.g., React, Next.js, or Vue) to build developer dashboards, API key management tools and analytics views.

Data & Cloud Infrastructure

- Production experience with SQL (e.g., PostgreSQL, MySQL) and/or NoSQL (e.g., Redis for caching/rate-limiting, MongoDB, or ClickHouse for analytical data).

- Hands-on experience with cloud infrastructure platforms, specifically AWS or Google Cloud Platform (GCP).

- Familiarity with containerization (Docker) and modern CI/CD pipelines.

Engineering Discipline

- A strong testing culture: Deep commitment to writing testable code with a solid grasp of unit testing framework habits (e.g., go test, pytest, Jest).

- Obsession with performant code: Understanding of time/space complexity, memory management, and identifying performance bottlenecks.

Nice-to-Haves (Preferred Qualifications)

- AI/LLM Knowledge: Familiarity with the AI ecosystem (OpenAI API, Anthropic, Hugging Face, LangChain, or Ollama). Understanding how tokenization, embeddings, and prompt structures work is a massive plus.

- Experience building tools specifically for developers (APIs, SDKs, or CLI tools).

- Knowledge of edge computing or serverless architectures (AWS Lambda, Cloudflare Workers).

- Experience handling real-time data streaming or WebSockets.
