Descrição

• Design and implement an ISO 13209-compliant OTX runtime, covering the full object model, deserializer, and type system. • Build a tree-walking interpreter for the OTX XML-based DSL, including AST design using sealed/algebraic data types. • Implement a variable scoping and parameter binding engine faithful to the OTX specification. • Develop the evaluator and executor pipeline, ensuring correct handling of procedural flows, conditions, loops, and exception handling as defined in ISO 13209-1/2. • Design and implement the OTX extension framework to support runtime-loadable extensions. • Handle streaming XML parsing with namespace resolution and xsi:type polymorphic deserialization. • Integrate the runtime with a D-Server layer: implement ODX parsing, service catalog management, and UDS request/response encoding and decoding. • Implement built-in OTX extensions including DiagCom adapter, PDU-to-J2534 adapter, and log:/file:/str:/ext:/flash:/even: extensions. • Develop diagnostic application logic targeting J2534 and D-PDU API (ISO 22900-2) diagnostic interfaces. • Support flash programming workflows across multiple OEM configurations. • Ship the runtime as a Kotlin Multiplatform (KMP) library targeting JVM and native platforms. • Write robust concurrent code using Kotlin Coroutines and Mutex primitives; debug and resolve production deadlocks. • Define and maintain a comprehensive test suite covering OTX conformance, edge cases in diagnostic protocol encoding, and runtime stability. • Participate in design reviews, contribute to internal documentation, and mentor team members on OTX and diagnostic protocol topics.

🎯 Requisitos

• Shipped an OTX-compliant runtime to production in any language. • Participated in development of a D-Server diagnostic interface, including ODX parsing and executing UDS services across multiple OEMs. • Deep, subject-matter-expert knowledge of ISO 13209-1/2 (OTX) and ISO 22901-1 (ODX). • Shipped at least one Kotlin Multiplatform (KMP) library to production. • Production experience debugging concurrency issues using Kotlin Coroutines and Mutex. • Implemented a tree-walking interpreter for an XML-based DSL. • Designed ASTs using sealed or algebraic data types. • Handled streaming XML parsing with namespace resolution and xsi:type polymorphism. • Strong command of Kotlin; candidates with equivalent depth in Java, Scala, or C# will also be considered. • Subject-matter expert in UDS (ISO 14229), ISO-TP (ISO 15765), and CAN/CAN-FD (ISO 11898). • Experience developing diagnostic applications targeting J2534 and/or D-PDU API (ISO 22900-2). • Working knowledge of KW2000 and OBD-II (SAE J1979). • Experience with flash programming is a strong plus. • Hands-on experience with commercial OTX authoring tools (e.g., ETAS EDIABAS OTX Studio, SOFTING). • Familiarity with commercial ODX authoring tools (e.g., Mazel & Quack OTX/ODX Editor). • Experience with heavy-duty vehicle diagnostics (SAE J1939).
