About The Position

John Deere is seeking a Display SIL Test Infrastructure Engineer to join their team in Dubuque, IA. This role focuses on improving and maintaining the SIL Display environment for Construction & Forestry teams, enabling the development and verification of next-generation display software. The engineer will be responsible for building Linux-based runtimes, expanding automated GUI test coverage, and ensuring the stability and usability of the SIL toolchain. This is an onsite position.

Requirements

Experience developing and/or maintaining software in a Linux environment (build, debug, scripting, and dependency management)
Demonstrated problem-solving skills to diagnose and resolve complex issues across software, environment configuration, and tooling
Experience building or maintaining automated test environments (SIL/HIL/MIL) or CI pipelines for embedded or UI software
Strong communication skills with ability to work across development, PV&V, and operations teams to deliver reliable environments
Experience writing maintainable scripts and utilities (e.g., Python, Bash) and using source control workflows (Git)
Ability to work in a self-directed mode while balancing sustainment work with incremental improvements and new features

Nice To Haves

Experience with display software development and/or verification, including UI automation and test strategies (SIL preferred)
Experience with NGPD/G5 display platforms (or similar embedded display stacks), including build, deploy, and runtime troubleshooting
Experience with Linux, Squish, Qt/QML, and one or more languages such as C/C++/C# and Python; familiarity with Jenkins and container/virtualization tools is a plus
Experience troubleshooting complex systems using logs, traces, and debuggers; ability to reproduce issues and drive them to resolution
Experience building repeatable developer workflows (installers, scripts, environment setup, documentation) for multi-team usage
Experience integrating automated tests into CI with reliable execution, reporting, and triage practices
Experience with networked/vehicle communication in test environments (e.g., CAN/J1939, Ethernet) is beneficial but not required
Familiarity with Construction & Forestry machine workflows and operator

Responsibilities

Contribute to the Display SIL environment for Linux based display software to support Construction & Forestry development and verification activities
Develop and maintain display simulation hooks, stubs/mocks, and interfaces needed to run display software in SIL
Expand and sustain automated GUI test coverage using Squish (test architecture, libraries, baselines, execution stability)
Partner with display software and PV&V teams to diagnose failures and improve SIL usability, performance, and reliability
Build and maintain the SIL toolchain (build/run scripts, launchers, logging, configuration management) and keep documentation current
Integrate SIL and Squish execution into CI (e.g., Jenkins) with actionable reporting and fast feedback to development teams
Support both domestic and international engineering teams by troubleshooting environment issues and enabling efficient workflows
Implement best practices for versioning, branching, and release of SIL assets (scripts, configs, test libraries) to minimize regressions
Create onboarding material and provide technical guidance to new users of the SIL Display environment and Squish framework
Plan, coordinate, and assist execution of Display SIL runs (local and CI) and help teams interpret results
Define and maintain environment health metrics (execution stability, flakiness, runtime, failure modes) and drive continuous improvement
Collaborate with internal stakeholders and tool vendors as needed to integrate and support SIL/Squish capabilities
Work with stakeholders to reproduce, triage, and resolve issues found during SIL execution and automated GUI testing
