Senior Software Engineer

Description

About the role

flō Optics is developing breakthrough digital printing technology for optical lens coatings. We are looking for an experienced Senior Software Engineer to join our R&D core team.

In this role, you will take ownership of core software modules driving our next-generation machines. You will work across the stack-connecting machine control logic, high-performance data/image processing routines, and modern UI workflows into clean, modular, and reliable software.

Key Responsibilities

• Application & Service Infrastructure: Develop robust desktop/edge backend services that handle machine sequencing, recipe/job management, data logging, and external system communications.
• Modern Interface Decoupling: Build modular software layers that cleanly separate low-level machine logic from application workflows and modern, responsive UI interfaces.
• Algorithm & Pipeline Integration: Collaborate with algorithm and image processing specialists to wrap and integrate complex computational models into production-ready, real-time machine execution pipelines.
• Hardware & Control Interfacing: Work closely with the motion and control team to establish well-defined communication protocols and APIs (e.g., REST, gRPC, IPC, JSON) between controllers and high-level software in addition to industrial PLC protocols (OPC UA, ADS, Modbus, etc.)
• Software Excellence: Implement best practices in code maintainability, automated unit/integration testing, CI/CD pipelines, and modern AI-assisted engineering workflows.

Requirements

• Education: B.Sc. in Computer Science, Software Engineering, Electrical Engineering, or equivalent.
• Experience: 5+ years of software development experience within complex multidisciplinary systems (semiconductor, digital printing, robotics, medical devices, or industrial automation).
• Deep Stack Competence: Strong proficiency in C# (.NET Core), Modern C++, or Python, with hands-on experience designing modular, multi-service or event-driven applications.
• Interface & Data Flow Design: Proven track record of designing clean API boundaries, data pipelines, and separating backend business logic from frontend user interfaces (e.g., modern desktop MVVM frameworks, Web-based UI/Electron).
• Database & Connectivity: Solid experience with database design (SQL/SQLite) and robust inter-process communication (IPC / network sockets).
• System Integration: Solid hands-on experience debugging and stabilizing software integrated with physical hardware, sensors, and actuators.

Advantages:

• Background in digital printing, printhead control, RIP engines, or industrial motion systems.
• Experience integrating image processing or computer vision libraries (OpenCV).
• Experience with containerization, deployment pipelines, or Linux/Windows edge environments.

Soft skills:

· Strong communication skills in English; ability to work effectively in a fast-paced startup environment.
