# Automation Programmer for Custom PLC & HMI

We are looking for an experienced **automation programmer** to support our industrial projects.

Our team will handle:

- Customer requirements
- Process study
- Control philosophy
- Sequence of operation
- I/O requirements
- Interlocks and operating conditions
- HMI screen requirements

The programmer’s role will be to **implement the provided control logic on our custom PLC and develop the required operator HMI screens**.

Main tasks:

- Convert our provided control logic and sequence into PLC software
- Program digital and analog I/O functions
- Implement timers, counters, interlocks and alarms as specified
- Develop HMI screens based on our provided design and operating requirements
- Connect PLC variables to the HMI
- Test and troubleshoot the software

The custom PLC uses a **C/C++ based control framework**, so experience with C/C++ and industrial automation is preferred.

Experience with PLC and HMI systems is important, but the engineer will **not be responsible for designing the industrial process or control philosophy**.

We are mainly looking for a reliable programmer who can accurately convert our prepared automation design into working PLC and HMI software.

This can become a long-term cooperation for multiple upcoming automation projects.

Please provide examples of similar PLC/HMI programming work and your preferred hourly or project-based rate.
