As a Software Developer:
Generalist, you will design, develop, test, and deliver offerings using leading‑edge and/or proven technologies. You will work in an Agile, collaborative environment to understand stakeholder requirements and contribute to the development of innovative software solutions.

Your primary responsibilities will include:

• Develop Component‑Level Solutions:
  Design, code, and test innovative component‑level software solutions, ensuring that the implemented solutions are unit tested and ready to be integrated into their product.
• Contribute to CI/CD Pipeline:
  Contribute to the automated CI/CD pipeline that takes code through various quality stages, ensuring seamless integration and delivery.
• Debug Customer‑Reported Problems:
  Design, develop, and unit test code fixes for customer‑reported problems, collaborating with stakeholders to resolve issues efficiently.
• Deliver Offerings:
  Deliver high‑quality offerings using leading‑edge and/or proven technologies, meeting stakeholder requirements and expectations.
• Collaborate with Stakeholders:
  Work in an Agile, collaborative environment to understand stakeholder requirements, providing input and guidance to ensure successful solution delivery.

In this role, you will help target runtime compilation and dynamic code generation for accelerated execution for GPU‑accelerated Watsonx.data. You will work on the layer that transforms logical operations into efficient executable paths for heterogeneous compute environments in Velox.

• Design and implement dynamic code generation for accelerated operators.
• Optimize compilation strategies for runtime efficiency and maintainability.
• Improve execution planning interfaces between engine logic and generated code
• Work with GPU and engine teams to expose more operations to acceleration paths
• Build debuggability and correctness checks into generated‑code workflows.

• Software Development & Compiler Engineering Expertise:
  Proven experience designing, developing, testing, and delivering high‑quality software solutions using leading‑edge and proven technologies, with deep hands‑on expertise in compiler frameworks, language runtimes, and code generation (e.g., LLVM, MLIR, or equivalent), supported by strong C++ proficiency and systems‑level reasoning.
• Component‑Level Design & Code Generation:
  Strong experience designing, coding, and testing innovative component‑level solutions, including compiler passes and optimizations, ensuring correctness, performance, unit testing, and seamless integration within execution engines and runtime systems.
• Runtime Systems & Query Processing Knowledge:
  Familiarity with execution engines and query‑processing internals (e.g., Velox, vectorized execution), enabling effective optimization across runtime‑generated and host code for high‑performance data processing workloads.
• Advanced Debugging & Problem Resolution:
  Demonstrated expertise debugging complex issues across compiler‑generated and host code, with the ability to design, implement, and unit test robust fixes while collaborating with stakeholders to resolve problems efficiently.
• Agile Development & CI/CD Enablement:
  Experience working in Agile, collaborative environments and contributing to automated CI/CD pipelines, enabling continuous integration, testing, and reliable delivery of…
