About the job
As a Senior SDK Developer, you will be a part of the team that works on the development of the new and cutting edge Tether AI SDK.
Responsibilities
* Developer-Facing SDKs & APIs: Tether is committed to delivering world-class developer experiences through robust and intuitive SDKs. You will design, build, and maintain modular, versioned SDKs that abstract complex backend logic into clean, usable interfaces — enabling seamless integration with Tether’s platform across various client environments.
* Performance & Reliability at Scale: SDKs must be fast, lightweight, and reliable — even when performing heavy and demanding operations. You’ll design resilient logic (retry policies, offline handling, batching) and contribute to the scalability of platform-facing interfaces and services powering the SDKs.
Security
Security-First Engineering: You’ll embed best-in-class security practices directly into the SDK architecture, including secure communication, encrypted storage and rigorous input validation. Your work will help ensure safe integration pathways for all developers working with the Tether ecosystem.
Qualifications
* +6 years of experience with Node.js/JavaScript in production environments.
* Proven track record in designing and maintaining developer-facing SDKs (npm packages, API clients, or instrumentation libraries).
* Strong understanding of modular architecture, versioning strategies, and semantic API design.
* Have actively participated in the development of a complex platform.
* Ability to quickly learn new technologies.
* Good understanding of security practices.
Nice to have
* Familiar with peer-to-peer technologies (Kademlia, BitTorrent, libp2p).
* Comfortable with high-availability concepts.
* Rust or C++ skills are a plus.
* Familiar with AI domain applications (RAG, Agents, Inference, AI SDKs).
* Familiarity with real-time data delivery (Node.js/other streaming).
