Role Overview

CS TECH Ai is seeking a Controls Software Development Engineer to bridge traditional industrial automation with contemporary software engineering. The role focuses on developing software tools that automate the deployment, retrieval, backup, comparison, and version control of shop-floor programs for PLCs, industrial robots, and CNC machines.

The ideal candidate will combine hands-on PLC programming and industrial automation expertise with strong software development skills in C#/.NET and Python. The objective is to replace manual engineering activities with secure, reliable, repeatable, and auditable workflows while maintaining production safety and manufacturing uptime.

Key Responsibilities

1. Industrial Automation & Tool Development

- Design, develop, and maintain software utilities to automate program uploads, downloads, retrieval, backup, and deployment for Siemens PLCs, Rockwell PLCs, ABB robots, and CNC systems.
- Develop integrations with Siemens TIA Portal Openness, Rockwell Studio 5000 automation interfaces and SDKs, and ABB Robot SDKs or Robot Web Services.
- Automate engineering workflows for PLC logic, robot programs, and CNC part programs to reduce manual intervention and improve operational consistency.
- Develop reusable software components and automation frameworks that support multiple device types and engineering environments.

2. PLC Programming & Engineering Integration

- Develop, modify, and troubleshoot Siemens PLC programs using TIA Portal for S7-1200 and S7-1500 controllers.
- Work with Rockwell ControlLogix and CompactLogix platforms using Studio 5000 / Logix Designer.
- Develop and maintain PLC logic, including Ladder Diagram (LAD), Function Block Diagram (FBD), Structured Control Language (SCL), standard function blocks, and Add-On Instructions (AOIs).
- Work with engineering project files and formats, including L5X and L5K, for program comparison, extraction, and controlled updates.
- Integrate engineering software with PLCs and other shop-floor automation systems using supported interfaces and communication protocols.

3. Automated Deployment, Backup & Version Control

- Build automated workflows for program retrieval, scheduled or controlled backups, deployment, and restoration.
- Implement change detection and comparison mechanisms to identify differences between online device programs and offline engineering versions.
- Maintain version histories with traceability of who made a change, what changed, when it occurred, and why.
- Integrate with Git/GitHub and industrial version management or backup solutions such as octoplant, versiondog, or Rockwell FactoryTalk AssetCentre.
- Develop reliable rollback and recovery mechanisms to support controlled restoration of previously validated programs.

4. Safety, Governance & Change Management

- Implement deployment safeguards, including approval workflows, device-state validation, pre-update backups, and controlled release procedures.
- Introduce appropriate interlocks and execution checks to prevent unintended changes to production-critical equipment.




- Ensure program updates follow established engineering approvals, change management procedures, and plant safety requirements.
- Design workflows to minimize operational disruption and preserve manufacturing availability.
- Maintain auditable records of program changes, approvals, deployment activities, backups, and recovery operations.

5. Testing & Virtual Validation

- Validate software tools and deployment workflows using available simulation and emulation environments, including Siemens PLCSIM Advanced, Rockwell Logix Echo, and ABB RobotStudio.
- Test program comparison, backup, deployment, restoration, and failure-recovery scenarios before production rollout.
- Develop repeatable test cases to verify application reliability, data integrity, and expected device interactions.
- Investigate software-to-hardware integration issues and perform structured root-cause analysis.
- Document test results, identified risks, corrective actions, and deployment readiness.

6. Robotics & CNC Integration

- Develop automation utilities for ABB robot program backup, retrieval, module management, and controlled updates.
- Work with ABB PC SDK, Robot Web Services, or equivalent supported interfaces.
- Support CNC part-program transfer and management workflows for Siemens SINUMERIK and FANUC systems.
- Integrate applicable CNC interfaces, including FANUC FOCAS where required.
- Extend the automation framework to other robot and CNC platforms as project requirements evolve.

7. Interfaces, APIs & Documentation

- Develop lightweight web interfaces, APIs, or supporting utilities that expose program status, device health, backup history, version differences, and deployment results.
- Build integrations that allow plant engineering teams to access automation workflows and operational information efficiently.
- Maintain technical documentation, interface specifications, configuration guides, test evidence, and user instructions.
- Collaborate with plant controls engineers, IT teams, maintenance personnel, and software engineering stakeholders to define requirements and resolve technical issues.

Mandatory Technical Skills

- Siemens Automation: Hands-on experience with TIA Portal, S7-1200/S7-1500 PLCs, and LAD, FBD, and SCL programming.
- TIA Portal Integration: Practical experience with TIA Portal Openness for automating engineering tasks.
