The role

This person will develop and maintain client SDKs in Python, C++, and Java. They will manage the protoc and buf toolchain, CI pipelines, and documentation for the robot platform.

What you will do

• Manage protoc and buf toolchain for client-side code generation
• Develop Python client SDK with idiomatic wrappers and pip wheels
• Develop C++ client SDK with RAII channel lifecycle and Conan/vcpkg packages
• Develop Java client SDK with builder patterns and Maven Central artifacts
• Handle channel lifecycle including timeouts, reconnection logic, and TLS/mTLS configuration
• Map gRPC status to language-idiomatic exception types
• Manage client/server version-skew compatibility and policies
• Implement semantic versioning and deprecation policy enforcement
• Create simulation-mode toggles for offline app development
• Implement observability hooks including structured logging and OpenTelemetry tracing

Required qualifications

• Developer experience with platform SDKs having shipped client libraries used by customers
• Proficient in at least two: modern Python (typing, asyncio, pyproject.toml/wheels), modern C++ (17/20, async patterns, build systems), Java (CompletableFuture, Maven build)
• Hands-on with gRPC ecosystem including protoc, buf, grpc-python, grpc-java, grpc-cpp
• Experience with multi-language packaging including manylinux pip wheels, Conan or vcpkg recipes, and Maven Central publishing

• Capability of owning end-to-end documentation deliverables using Sphinx, Doxygen, or MkDocs
• Understanding of cross-language async patterns and gRPC trade-offs

Nice to have

• Familiarity with robotics or industrial control
• Experience writing language bindings for a native library (PyBind11, JNI, SWIG, cppyy)
• Authored OpenTelemetry instrumentation libraries across multiple languages
• Working knowledge of ROS 2 client library design (rclpy / rclcpp)
• Written a developer-portal API reference or SDK tutorial series for external developers
