The role involves solving complex engineering challenges and collaborating on technology that supports scientific workflows.
Description
Backend Software Engineer — Titan Instrument PlatformAbout the roleYou'll join the team building the control software for Titan, an automated slide-staining instrument used in histology and immunohistochemistry (IHC) labs.
What you'll do• Extend and maintain the .NET backend that runs staining protocols end-to-end: slide/reagent scanning, fluid handling, heating, and multi-step IHC/H&E staining sequences
• Build and debug the IPC layer between the backend and the Electron/GUI frontend, adding new commands and events as features require
• Work directly with instrument hardware: serial-port communication, RFID reagent/slide identification, barcode scanning, pumps, valves, and fluid-level sensors
• Diagnose and fix issues that span software and hardware — timing, race conditions, sensor noise, and mechanical fault handling
• Maintain protocol and configuration data (staining protocols, machine settings, kit registration) and the client that syncs it with the lab's shared database
• Write and improve automated maintenance/self-test routines (heater checks, valve exercises, module cleaning) and error-recovery logic
What you bring• Professional experience in C#/.NET (.NET 6+)
• Comfort working in a multi-threaded, stateful, long-running service — this backend manages a stateful singleton instrument controller, not a stateless API
• Experience with hardware/IPC integration: serial communication, device drivers, or similar embedded/lab-automation work
• Ability to read and extend a large existing codebase with real hardware dependencies, including debugging issues that only reproduce on physical equipment
• Solid fundamentals in async/await, event-driven architecture, and defensive error handling for equipment that can't simply "retry the request"
• Willingness to work on-site with the instrument for testing and validation
Nice to have• Experience with laboratory, medical device, or other regulated hardware software (IVD, FDA/QMS-adjacent development practices)
• Familiarity with Electron or other desktop app frameworks, since the backend talks directly to an Electron GUI
• Experience with barcode/RFID scanning systems or robotics/motion control (XYZ stages, steppers)
• Exposure to ML inference in .NET, for tasks like image-based slide or tissue classification
• Prior work with JSON-based protocol/config-driven systems and versioned settings migrations
• Experience with C/C++, Python, node.js
• Bilingual proficiency: Fluent in English and Chinese (written and verbal)
Tech environmentC#, .NET 6+, Serial Ports, Visual Studio / MSBuild
