Descrizione del lavoro

We are looking for a Senior Programmer/Architect (C++ / C#) with deep architectural experience in software development for industrial machines and automation systems. The candidate will define the code design guidelines for machine-level software and act as a technical mentor to the team, while remaining hands‑on.

This role directly reports to the R&D product leader in their region with a dotted line to the Sr. Director of Software Development based in Spain.

Key Responsibilities

• Design, develop, and optimize the software architecture for the control, diagnostics, and supervision of complex industrial machines, ensuring efficient coexistence between C++ (real‑time/low‑level management, drivers, high‑performance data processing) and C# (HMI, application logic, connectivity).
• Lead the technology choices of the industrial software development team, define coding standards together with the team to ensure maximum machine stability and safety, and conduct rigorous code reviews.
• Explore new technologies and industrial protocols, creating Proofs of Concept (PoCs) to improve machine performance, efficiency, and connectivity.
• Work closely with the electronic design, automation (PLC), and mechanical teams to translate machine operating specifications into robust software architectures.
• Act as a reference point for less experienced programmers, helping them solve complex software/hardware interface issues.

Requirements

• Proven experience in developing application or control software for industrial machines, plants, or complex embedded systems.
• Deep knowledge of software‑hardware interaction dynamics (input/output management, machine cycles, alarm management, and machine state management).
• Excellent knowledge of modern C++, concurrent/multithreaded programming, memory management, and performance optimization for critical low‑level tasks.
• Solid experience with the .NET ecosystem (Framework + Core) for developing advanced human‑machine interfaces (HMI), supervision services, and coordination logic.
• Familiarity with the integration of industrial protocols and fieldbuses (e.g., OPC UA, EtherCAT, Modbus, CANopen, TCP/IP).
• Good experience integrating low-level native code with high-level managed code (C++/CLI, P/Invoke).
• Use of profiling and debugging tools in industrial environments, unit testing frameworks, and version control systems (Git).
• Ability to guide and influence the team’s decisions through technical credibility and expertise.
• Strong aptitude for understanding the impact of code on the physical behavior of the machine and on operational safety.
• Ability to analyze complex bugs or abnormal machine behaviors in a structured way, focusing on the long‑term stability of the system.

What can we offer?

• Direct Product Impact: The opportunity to see your code move, control, and optimize real, state‑of‑the‑art industrial machines.
• Focus & Flow: Protected time for research, development, and architectural design, minimizing corporate bureaucracy.
• Exposure: The candidate will interact with counterparts across the EFI group to develop international projects.
