Senior Software Engineer (C++, SECS/GEM)

Responsibilities

• About the role You will own the software layer between back-end production equipment and the factory systems (MES, host, test data servers).
• Equipment integration and control Design, develop and maintain SECS/GEM interfaces (SEMI E4/SECS-I, E5/SECS-II, E30/GEM, E37/HSMS) between back-end equipment and host/MES systems.
• Integrate new and existing die bonders, wire bonders, moulding systems, testers, handlers and AOI tools, including collection events, alarms, variables, remote commands and recipe management.
• Support equipment qualification, factory acceptance and site acceptance testing for automation software.
• Legacy systems and interfaces Maintain and extend legacy integrations built on SOAP web services, XML and proprietary protocols.
• Maintain, debug and modernise existing Ada and C++ applications while keeping production lines running.
• Build connectors and adapters between legacy services and newer platforms, including message-bus based integration (e.g. JMS).
• Wafer maps and test data Develop and support software that handles wafer maps (e.g. SEMI E142, SINF/TSK and vendor formats) for die picking and bin tracking.
• Handle test data flows (e.g. STDF, bin summaries, lot/yield data) from testers to data servers and yield systems.
• Ensure data integrity and traceability across lots, wafers, strips and units.
• Support, quality and collaboration Provide second- and third-line support for production issues, including root-cause analysis and permanent fixes.
• services, configuration, scheduled tasks, logs and patches in cooperation with IT.
• Build and maintain simple internal web tools (HTML, JavaScript, CSS) for engineering use.
• Write technical documentation, follow change-control procedures and participate in code reviews.
• Work with equipment, process, test and IT engineers, and with equipment vendors, to resolve interface issues.
• Mentor junior engineers and share knowledge within the team.

Requirements

• Good knowledge of Windows as an operating system: services, networking, file shares, registry, event logs and troubleshooting.

Maintain Windows-based equipment PCs and servers

Master’s or Bachelor's Degree in Computer Science, Software Engineering, Electrical/Electronic Engineering, Mechatronics or a related field. At least 5 years of software development experience, including 3+ years in semiconductor or electronics manufacturing automation. Hands-on experience in a back-end assembly and test environment; experience at a semiconductor manufacturer (e.g. Infineon, STMicroelectronics, onsemi, Intel) or an OSAT or equipment supplier is an advantage. Working knowledge of SECS/GEM (SECS-II messages, GEM state models, HSMS) and practical experience connecting equipment to a host or MES. Proficiency in C++ (or Ada); readiness to maintain Ada code if coming from C++. Experience with SOAP web services, WSDL and XML, and other legacy communication protocols.

Understanding of back-end processes and equipment

die bonding, wire bonding, moulding, test and AOI. Knowledge of wafer maps and semiconductor test data (formats, binning, lot and wafer genealogy). Basic web development skills in HTML, JavaScript and CSS.

Solid debugging skills, including reading SECS logs and network traces. Good command of English, written and spoken; Bahasa Malaysia is an advantage.
