Job description

Position Purpose

The Software Engineer leads full-stack software development for medical In Vitro Diagnostic (IVD) devices and provides software engineering support for biological analysis software packages. This role bridges low-level hardware interaction and high-level user interfaces, developing robust software applications, configuring operating system environments, and verifying code against established regulatory and technical specifications. The engineer will design and build intuitive UI/UX for non-technical users to control complex scientific instruments, interface directly with microcontrollers and embedded hardware, and enable automated analysis of complex biological datasets to provide actionable information to end users.

• Lead full-stack software development efforts for medical IVD systems and biological analysis software, spanning lower-level microcontroller/hardware interfaces to upper-level application logic and user interfaces.
• Design, build, and refine intuitive graphical user interfaces (UI/UX) that enable scientific personnel and non-technical operators to control analytical instruments and sensor networks.
• Program, integrate, and test low-level microcontrollers (e.g., Arduino or similar platforms) to communicate with biological sensors, custom boards, and peripherals.
• Write, test, and optimize high-performance C++ codebases as well as Python applications for instrumentation control, data processing, and analytical workflows.
• Implement cybersecurity controls, software hardening procedures, and secure coding practices within production and operational environments.
• Adhere to quality management system (QMS) protocols and regulatory/ISO standards (e.g., ISO 13485, ISO 62304) throughout the software development lifecycle, including formal design controls, risk assessments, and code documentation.
• Collaborate with cross-functional teams—including biologists, systems engineers, hardware developers, and project leads—to translate technical wireframes and scientific requirements into production-ready software.
• Troubleshoot and debug complex hardware/software integration issues, recreating user workflows to isolate root causes and optimize operating efficiency.
• Author and maintain software lifecycle documentation, design specifications, verification/validation protocols, and end-user operating manuals.
