Brownfield Retrofit Engineer_PS

Job description

Job Summary Brownfield Retrofit Engineer Lead equipment modernization for legacy production equipment and control systems covers the full chain from original equipment state, through library validation, to hardware commissioning — combining deep PLC competence with project management and industrial deployment capability. Roles and Responsibilities 1. Original Equipment Understanding & Assessment Digest and understand original equipment state — mechanical function, electrical schematics, control logic, and underlying process intent — as the baseline for any upgrade decision. Conduct technical assessment and modernization roadmap for legacy equipment, focusing on Brownfield feasibility and risk control. 2. Project Management Manage Brownfield upgrade projects — scope, schedule, resources, risk, and stakeholder coordination across TEF3, production, and external partners. Track milestones, dependencies, and deliverables against the WP0 roadmap; escalate risks and drive mitigation. 3. Test Bench & Legacy Communication Establish test benches and validation environments for legacy components, enabling communication control testing before migration. Operate the AI-assisted conversion tool to generate candidate Nexeed Automation library blocks and control programs from legacy sources. 4. AI Tool Usage & Library Validation Operate the AI-assisted conversion tool to generate candidate Nexeed Automation library blocks and control programs from legacy sources. Read, review, and validate the generated library code — verify functional equivalence against legacy baselines and ensure correctness before release. Build and standardize reusable PLC libraries for the new platform, accumulating in-house library capability over successive upgrades. 5. Hardware Commissioning & Field Deployment Lead hardware commissioning — integrate PLC, peripherals, drives, safety, and mechanical interfaces; perform FAT, SAT, and ramp-up support. Troubleshoot field issues across hardware, bus, PLC logic, HMI, MES, and mechanical interaction layers. Document and transfer knowledge to TEF3 colleagues, enabling the team to sustain upgraded systems independently. Qualifications Requirement Education degree: Bachelor or Master degree in Mechanical Engineering, Electrical Engineering, Automation, Computer Science, or related fields. 5+ years of hands-on PLC engineering and industrial automation experience, including brownfield / legacy system exposure. Job Relevant Knowledge and Experience Deep PLC hardware and software engineering competence — covering legacy controllers, target ctrlX platform, and fieldbus communication Able to design library structures, define block interfaces, and apply software engineering discipline to PLC code. Ability to read and review AI-generated library code and verify functional equivalence against legacy baselines — deep PLC expertise is the core requirement; AI tool fluency can be built on the job. Hands-on commissioning of PLC hardware, peripherals, drives, safety relays, and I/O modules; able to read electrical drawings and integrate at the hardware level. Strong communication and cross-functional collaboration skills.
