Job description

About the Opportunity

At Skyven Technologies, we have developed a revolutionary heat pump technology to decarbonize industrial heat and move the needle on climate change. Our technologies have the potential to completely eliminate on-site CO2 emissions from industrial steam. We implement this technology through an innovative Energy-as-a-Service model that provides clean process heat to industrial facilities. We identify, fund, design, build, and install our cutting-edge, decarbonization technologies to help industrial manufacturers reach their sustainability goals, while minimizing their risk and reducing their operational expenses.

Industrial heat is responsible for roughly 20% of global CO2 emissions. That’s roughly equivalent to emissions generated by all transportation (including land, sea, and air) and is a compelling business opportunity – it will take an estimated $3.7 trillion in capital investment to decarbonize the sector by 2050. Skyven is at the forefront of this transformation and has recently been selected for a $145M investment from the U.S. Department of Energy (DOE) to accelerate the deployment of our state-of-the-art Skyven Arcturus steam-generating heat pumps (SGHPs) at manufacturing facilities nationwide, revolutionizing how we address energy needs while combating climate change.

About the Role

We are looking for a skilled and driven PLC Software Engineer to support the design, development, and deployment of control software for our cutting-edge steam-generating heat pump systems. This role offers a unique opportunity to engage in true 0-to-1 software development, translating a controls narrative and PLC hardware architecture into a fully functioning, field-deployed system. You will be responsible for authoring detailed sequences of operation, writing and testing PLC code, and supporting the software throughout its lifecycle. Ideal candidates will have a strong foundation in PLC programming and a desire to deepen their expertise in Siemens S7 platforms, PID loop tuning, sensor integration, and VFD control within a dynamic engineering team.

Responsibilities

PLC Development & Software Engineering

Design, develop, and maintain PLC software for Siemens Simatic S7 PLCs and ET 200SP distributed I/O hardware.
Develop and maintain a version-controlled library of reusable Function Blocks (FB) and User-Defined Data Types (UDT), with basic version control tracking post-deployment.
Contribute to a scalable software architecture for various hardware configurations within the product platform.
Assist in creating and documenting guidelines for PLC library objects, configured code, and code documentation.

Controls and Automation

Develop sequences of operation in collaboration with mechanical and electrical teams, identifying and addressing gaps in control narratives during the process.
Integrate PID loops, sensors, and VFDs for continuous control applications.
Support the development of custom automation tools to aid the team in configuring and deploying code for different heat pump setups.

Testing and Commissioning

Assist in bench testing and limited simulation efforts, working alongside the SCADA team.
Help write and test basic commissioning scripts and startup procedures.
Troubleshoot and resolve PLC software bugs during commissioning and post-deployment phases.

Requirements

B.S. in Computer Science, Electrical Engineering, or related engineering discipline.
5-7 years of experience in software development with a focus on PLC programming.
Proficiency in Structured Control Language (SCL) and Function Block Diagram (FBD) according to IEC 61131-3 standards.
Experience writing and testing code for Siemens PLCs (Simatic S7, ET 200SP DIO), with some exposure to PID control, sensors with various signal types, and VFDs.
Familiarity with industrial communication protocols (e.g., PROFINET, OPC-UA, Modbus).
Ability to write sequences of operation and implement descriptive user-defined data types.
Strong problem-solving skills and a willingness to learn and grow in a fast-paced environment.

Preferred

Experience using simulation tools for PLC testing.
Basic skills in developing automation tools/scripts (Python, etc.) for PLC configuration.
Familiarity with commissioning test scripts for control systems.
Knowledge of fluid systems and steam processes.
Exposure to functional safety, safety PLCs, and SIL requirements.
