Preferred Qualifications * Experience with SQL or other databases for storing and retrieving machine or process data. * Experience with GitHub or other source control platforms. * Working knowledge of Python for scripting, data processing, or test automation. * Experience with other industrial controls platforms, such as Allen-Bradley PLCs, HMIs, Ignition, robotics, or machine vision systems. * Ability to read and understand electrical schematics. ## Description We are looking for a Controls Programmer who combines strong C#/.NET development skills with a hands-on understanding of industrial hardware. In this role, you will work primarily on advanced test and process equipment we build for one of our key customers in the solar manufacturing industry. Most of these systems are PC-controlled, meaning the application you build is the sole controller, directly driving sensors, motors, drives, and data acquisition hardware in real time. We are looking for team players who enjoy working side by side with our controls engineers and technicians to design, build, and deploy software that keeps this equipment running reliably. Why Join SDC? * Software That Runs Real Machines: Your applications won't sit on top of the equipment; they'll be the controller, running machines on the plant floor and through months-long tests. * Collaborative Environment: Work closely with our controls engineers, technicians, and project managers from design through debug, runoff, and customer startup. * Family-Owned Culture: Experience a supportive and agile environment that values technical excellence and personal growth. What You'll Do * Design, develop, test, and deploy C# Windows applications that run on industrial machinery and interface directly with sensors, motors, drives, data acquisition devices, and other controls hardware. * Build and support applications where the PC serves as the primary controller in the system, managing Real Time I/O and device communication. * Work directly with controls engineers to understand machine behavior, hardware interfaces, and operator workflows, and translate them into clean, maintainable software. * Support deployment and troubleshooting of your applications during machine debug, runoff, and customer Factory Acceptance Testing (FAT). * Maintain and improve existing software tools and code libraries, applying good source control and documentation practices. * Collaborate with the controls team to identify where custom software can improve machine reliability, data visibility, or troubleshooting speed. * Travel approximately 10% to support customer startups and project implementation., * Deliver reliable, well-structured Windows applications that operators and engineers can use every day. * Build software that communicates cleanly and reliably with the sensors, motors, and hardware it controls. * Develop software capable of running months-long tests without interruption. * Communicate clearly with engineers, technicians, and project teams about what the software does and why. * Continuously improve our code libraries, tools, and development practices. * Help make every machine's software as solid as the hardware it runs on. What We Expect From Everyone at SDC * Every role at SDC is built on a shared set of expectations that define how we work together. * Demonstrate professionalism, integrity, and accountability in everything you do. * Treat coworkers, customers, suppliers, and partners with respect. * Communicate openly and collaboratively across all departments. * Take ownership by identifying issues early, proposing solutions, and following through. * Adapt to changing priorities while maintaining a positive, team-first attitude. * Produce high-quality, detail-oriented work that supports safety, quality, and continuous improvement. * Be dependable, willing to learn, and ready to support teammates whenever needed. * Contribute to a workplace built on trust, teamwork, and shared success. Why Join Steven Douglas Corp.? * Work on challenging, custom automation projects-not repetitive production support. * Collaborate with an experienced team of engineers, machinists, electricians, assemblers, and project managers. * See your designs come to life from concept through customer startup. * Help shape engineering standards and influence how future machines are built. * Grow your technical skills while working with robotics, vision systems, servo motion, AI-enabled inspection, and advanced automation technologies. * Join a stable, family-owned company committed to long-term growth, innovation, and investing in its people.
