About the role
At ON.energy, the Senior Controls Engineer for HMI/SCADA owns the visual design, layout, and functional behavior of every operator-facing screen across our energy storage and power infrastructure platforms. This is a screen-first role — the primary deliverable is a SCADA interface that operators trust, understand, and can act on instantly. The ideal candidate brings deep, hands-on experience with Ignition and its Perspective module, a sharp eye for information design in high-stakes environments, and the communication skills to gather requirements from field operators and translate them into polished, production-ready screens.
What you'll bring
- Bachelor's degree in Engineering, Human-Computer Interaction, Computer Science, Product Design, or a related field — or equivalent professional experience.
- Hands-on, production experience with Inductive Automation Ignition — including project configuration, tag management, alarm pipelines, and system integration.
- Demonstrated experience building and delivering Perspective module screens — components, bindings, scripting, styling, and responsive layout across device types.
- Deep understanding of industrial HMI design principles: information hierarchy, alarm visualization, color coding for process states, situational awareness, and operator-centered layout.
- Proven ability to gather requirements from and present deliverables to both internal teams (engineers, PMs, field techs) and external clients (operators, site managers, procurement stakeholders).
- Comfortable leading design reviews, workshops, and milestone presentations.
- Proficiency with wireframing or prototyping tools (e.g., Figma, Adobe XD, or equivalent) to communicate screen designs before Perspective development begins.
- Familiarity with Modbus, OPC UA, or similar — enough to understand tag structure, data availability, and how underlying data shapes what can be displayed on screen.
- Portfolio or examples of Perspective work strongly preferred.
- Experience in energy storage, renewables, or power infrastructure strongly preferred.
- Experience with BESS, inverters, or distributed energy resources (DER) and familiarity with their operational data and state models.
- Ability to read single-line diagrams and understand basic power system concepts — essential context for designing accurate and meaningful SCADA screens.
