Senior Software Engineer (SDK) at Clera

About the Role This is a high-ownership engineering role at a fast-growing, open-source AI engineering platform — think of it as the Datadog for LLM observability. The platform is trusted by thousands of development teams worldwide, and the SDKs you'll own are downloaded millions of times each month , often serving as the very first touchpoint a developer has with the product. The SDKs run in production environments ranging from serverless functions to long-running agent loops. They must be rock-solid: minimal CPU and memory overhead, zero tolerance for failure, and a developer experience that feels effortless. When you ship, thousands of developers benefit the same day. What You'll Do Own the Python and TypeScript SDKs end-to-end — reliability, performance, and developer experience. Set the bar for SDK quality across the organization. Design APIs developers love — naming conventions, parameter structure, breaking-change communication, and documentation. Every detail of the DX is yours
