The posting

Overview

Responsibilities

  • Ignition HMI Development: Lead the design, architecture, and deployment of commercial-grade operator interfaces standardized on the Ignition SCADA platform.
  • Site-Agnostic UI Architecture: Build dynamic, site-agnostic HMI screens and tag structures that seamlessly scale across diverse power plant configurations, skids, and high generator counts.
  • Protocol & Telemetry Integration: Implement robust communication interfaces and telemetry pipelines utilizing OPC-UA, Modbus, and SunSpec for real-time SCADA data exposure and third-party integration.
  • Alarming & Diagnostics: Develop comprehensive alarm management, system of events logging, and diagnostic dashboards for deep visibility into site hardware and network status.
  • Testing & Validation: Own the testing lifecycle for new features, including unit testing, integration testing, and hardware-in-the-loop (HIL) validation to ensure site safety logic and grid compliance.
  • DER Integration: Implement strategies for integrating Mainspring technology into Distributed Energy Resource Management Systems (DERMS) and complex microgrid environments.
  • Cross-Functional Collaboration: Work with Product, Controls and Hardware teams to translate utility requirements and interconnection standards into functional software specifications.

Qualifications

  • Industry Experience: 12+ years of hands-on experience in commercial power generation, industrial automation, manufacturing or utility-scale energy projects.
  • HMI & SCADA Expertise: Deep hands-on experience building complex industrial HMI/SCADA systems, with demonstrated mastery of the Ignition platform (Perspective/Vision modules, UDTs, Tag Historian) and industrial communication protocols, specifically OPC-UA, Modbus TCP/RTU, and SunSpec, alongside relational database integration (e.g., PostgreSQL).
  • Software Architecture & Scalability: Proven experience defining industrial software architecture, leading technical decisions, and delivering reusable, site-agnostic HMI/SCADA platforms from design through deployment.
  • Grid Interconnection Standards: Experience with grid interconnection standards (e.g., IEEE 1547, UL 1741).
  • Cybersecurity Frameworks: Knowledge of cybersecurity frameworks for industrial control systems (e.g., NERC CIP).
  • Technical Communication: Ability to create clear technical documentation and system diagrams that bridge the gap between industrial hardware and modern software.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
