Robot Client SDK Engineer (human)

YOUR MISSION & CHALLENGES - protoc + buf toolchain for client-side code generation; CI pipelines regenerate clients on every proto change - Python client SDK: idiomatic wrappers with context managers, async/await variants, IDE completion stubs, pip wheels published to internal PyPI - C++ client SDK: RAII channel lifecycle, async, language-idiomatic exception hierarchy, Conan/vcpkg packages - Java client SDK: builder patterns for requests, CompletableFuture, Maven Central artifacts - Channel lifecycle handling across languages: timeouts, deadline propagation, reconnection logic, TLS/mTLS configuration - gRPC status to language-idiomatic exception mapping: hierarchical exception types with semantically meaningful subclasses - Client/server version-skew compatibility tables—published policies on client-server version support, automated compatibility tests - Semantic versioning aligned with the platform architect, deprecation policy enforcement with linter warnings, migration guides - Simulation-mode toggle inside the client: same proto interface, simulation backend for offline app development - Observability hooks per language: structured logging, OpenTelemetry tracing context propagation, Prometheus client metrics - Reference example applications per language demonstrating canonical patterns: pick-and-place, mode switching, fault recovery, telemetry streaming - Auto-generated documentation per language: Sphinx (Python), Doxygen (C++), Javadoc (Java); examples kept in sync with API surface - Internal customer onboarding: skill bundles, evaluation harnesses, R&D notebooks, demo apps—all start from your reference template - RFC co-review with the Robot Platform Integration Engineer on every proto change WHAT WE CAN LOOK FORWARD TO - Developer experience with platform SDKs—has shipped client libraries used by external or internal 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: protoc, buf, grpc-python, grpc-java, grpc-cpp—has implemented production clients. - Multi-language packaging: manylinux pip wheels, Conan or vcpkg recipes, Maven Central publishing—experienced with full CI pipelines. - API design fluency: gRPC/REST/GraphQL, semantic versioning, deprecation policy authorship, backwards-compatibility analysis. - Documentation tooling: Sphinx, Doxygen, MkDocs; capable of owning end-to-end documentation deliverables. - Cross-language async patterns: understands trade-offs among sync, async, and streaming gRPC across languages and their ergonomic differences NICE TO HAVE - Familiarity with robotics or industrial control to discuss latency and timing semantics with robot platform engineers - 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
