Brownfield Retrofit Engineer

Job Description

Job Summary

BrownfieldRetrofit 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

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.
• Fluent English both in speaking and writing
