About Skyven Technologies

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.

About the Role

We’re seeking an experience PLC Engineer to support the development and validation of control logic for our steam-generating heat pump system using Siemens S7 PLCs. The role will require approximately 20 hours per week for 4–6 weeks, with a possibility of extension. Compensation will be offered at a negotiable hourly rate.

Technology Background

Skyven’s steam-generating heat pump system relies on Siemens S7 PLCs to manage complex control sequences for industrial heat processes. The PLC code is in an early stage of development with an established structure but is not yet polished, requiring in-depth effort to understand and optimize. The PLC Engineer will not need to comprehensively understand the entire codebase and system but will focus on developing and refining specific sections of Siemens S7 PLC code that integrate into the broader system.

Skyven’s steam-generating heat pump system uses Siemens S7 PLCs to control complex industrial heat processes. The PLC code is in early development with an established structured foundation but needs refinement. You won’t need to master the entire codebase; instead, you’ll focus on specific portions of the code, working from a provided Sequence of Operations (SOO) and collaborating with our internal team to integrate your work.

Key Responsibilities

  • Develop and refine Siemens S7 PLC code based on a provided Sequence of Operations (SOO
  • Review existing code to ensure it aligns with the SOO and identify any discrepancies
  • Support unit and simulation testing to verify expected behavior and edge cases
  • Offer recommendations to improve code performance and reliability
  • Participate in weekly one-hour video calls during U.S. East Coast business hours

Requirements

Ideal Candidate

  • Strong experience programming Siemens S7 PLCs in industrial settings
  • Proven ability to interpret and implement logic from a Sequence of Operations
  • Familiar with unit and simulation testing, including edge case scenarios
  • Solid understanding of industrial control systems and their field application
  • Comfortable working with early-stage codebases and improving them
  • Hands-on experience with real-world PLC implementation (not just simulations)

FAQS

Q: Am I expected to create a new PLC system from scratch?

A: No. You’ll be working within an existing structure and building out specific sections based on a defined Sequence of Operations.

Q: Do I need to understand the entire system and ensure it works perfectly?

A: No. You’ll focus on assigned parts of the code. System integration and oversight will be managed by the project lead.

Q: Does experience with other PLC brands qualify me?

A: Siemens S7 experience is preferred. However, strong experience with other PLC platforms and the ability to quickly adapt may be considered.

Q: Is experience with unpolished or early-stage codebases required?

A: Yes. You should be comfortable working with partially completed code and offering constructive feedback.

Q: Is there potential for future work?

A: Possibly. There may be opportunities for extension, new projects, or even a full-time role, but ongoing work is not guaranteed.

Benefits

  • 20 hours per week for 4-6 weeks, with potential for extension
  • Hourly rate negotiable
  • Fully remote; no travel required
