Primary Location: United States (US) - Iowa - Dubuque Function: Product Engineering (CA) Title: Display SIL Test Infrastructure Engineer - 121058 Onsite/Remote:Onsite Position ## Your Responsibilities As a Display SIL Test Infrastructure Engineer located in Dubuque, IA, you will improve and maintain the SIL Display environment used by Construction & Forestry teams to develop and verify next-generation display software (NGPD/G5). You will build reliable Linux-based runtimes, expand automated GUI test coverage (Squish), and support developers and PV&V engineers by keeping the SIL toolchain stable, repeatable, and easy to use. Additionally, you will: * 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 VISA Sponsorship is NOT available for this position ## What Skills You Need * 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 ## What Makes You Standout * Experience with display software development and/or verification, including UI automation and test strategies (SIL preferred) * Experience with NGPD/G5 display platforms (or...
