## About the Role

* Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, Computer Science, Electronics, Systems Engineering, or a closely related field.
 * 3+ years designing and owning Python-based applications and libraries (including desktop GUI applications).
 * 2+ years experience building and owning software that talks to physical hardware - instruments, microcontrollers, robots, sensors, or similar devices - not only software-to-software integrations.
 * Demonstrated software architecture and design judgment: usability, maintainability, extensibility, and performance, not only feature delivery.
 * Experience with Git and a defect-tracking system such as Jira.
 * Working knowledge of software verification and validation techniques (automated testing, integration tests, and checking work against requirements).
 * Travel globally u p to 15%

What Will Put You Ahead

 * PyQt (or a similar Python GUI framework) for desktop applications.
 * Comfort in a lab or on a manufacturing floor: supporting operators, reproducing hardware-in-the-loop failures, and traveling to plants as needed.
 * Experience with instrument or device I/O (VISA, SCPI, serial, or similar).
 * Ability to apply scientific Python to user-facing applications: NumPy, Pandas, SciPy, and a conda-based workflow.
 * Building reusable libraries, APIs, or configuration-driven frameworks that other engineers and testers use.
 * Clear written and verbal communication with non-software customers (manufacturing, test, and product engineers).
 * RF, VNA, or signal-integrity background will put you ahead.

## Description

This Software Design Engineer will join that career path. The first assignment is Atlas, a desktop platform used to run robot-based 67GHz vector network analyzer (VNA) test processes and replace older site-specific VNA tools. This tester solution will drive the next generation of 224G data interconnects and beyond.
What You Will Do

 * Design, implement, and maintain Python desktop applications used by electrical, mechanical, signal-integrity, and manufacturing engineers.
 * Own features in Atlas: process flow, robot/VNA control, configuration, results display, and the operator-facing workflow that runs on a test station that will be deployed to labs and production floors.
 * Integrate software with test hardware and automation - instruments, fixtures, and robots - so a configured process can run reliably in production.
 * Help migrate manufacturing sites from historical VNA platforms onto Atlas, including setup, debugging, and training users on the new workflow.
 * Work with product-family and process configuration so new parts and test sequences can be added without rewriting the application.
 * Support global manufacturing centers: reproduce failures, ship fixes, and make the tools usable for people who are not software developers.
 * Participate in the full development cycle: requirements, design, implementation, code review, verification and validation, documentation, and knowledge sharing.
 * Eventually you will own other SSG tools besides Atlas. This role is not for a single-product specialist., Our goal is for each employee, and their families, to live fulfilling and healthy lives. We provide essential resources and support to build and maintain physical, financial, and emotional strength - focusing on overall wellbeing so you can focus on what matters most. Our benefits plan includes - medical, dental, vision, flexible spending and health savings accounts, life insurance, ADD, disability, retirement, paid vacation/time off, educational assistance, and may also include infertility assistance, paid parental leave and adoption assistance. Specific eligibility criteria is set by the applicable Summary Plan Description, policy or guideline and benefits may vary by geographic region. If you have questions on what benefits apply to you, please speak to your recruiter.
Additionally, everyone has individual work and personal needs. We seek to enable the best work environment that helps you and the business work together to produce superior results.
