Job description
Nexus Engineering Group is employee-owned, full-service, and growing our Substation Department. As a Substation Engineer – Protection & Controls, you’ll develop the protection, control, and wiring design of high-voltage substation projects — and grow from production support toward independent design. You’ll produce the single-line and three-line diagrams, schematics, and wiring documentation — including protective relaying and SCADA/automation scope — that keep substations running safely and reliably. Working alongside a collaborative team of engineers and designers, you’ll take on more ownership as you develop, building toward independent design of substation protection and control packages. ### Why Nexus You’ll own a piece of what you build. Nexus is employee-owned through our ESOP, so the value you help create comes back to you — not just outside shareholders. We invest in our engineers and give them room to grow into greater ownership of the work. **What you can expect:** - Employee ownership (ESOP) — build equity in the firm as it grows - Real ownership that grows with you — from production support toward independent design - Mentorship from senior engineers and designers on a collaborative team - Full-service EPCm exposure, from concept through startup, across a diverse client base - Career paths that grow with you — toward technical leadership, project management, or discipline leadership - Flexible work arrangements where business needs allow ### What You’ll Do - Develop and revise single-line diagrams, three-line diagrams, schematics, and wiring documentation in CAD, with growing independence as you develop. - Build and maintain cable/conduit lists, nameplates, and client-specific documentation. - Assist the project lead in developing protection and control documentation, applying technical design standards. - Support protective relaying, SCADA/RTU, and automation design and interfaces within your scope. - Apply internal and external processes, procedures, and design standards (IEEE, ANSI, NEC, NESC). - Coordinate with drafters, designers, other disciplines, clients, and vendors to deliver complete, constructible packages. ### What We’re Looking For **Required Qualifications** - Bachelor of Science in Electrical Engineering, Electrical Engineering Technology, or a related discipline. - 2+ years of experience in substation, power delivery, or electrical design. - Proficiency with CAD (AutoCAD and/or AutoCAD Electrical). - Familiarity with the wiring scope — AC/DC schematics, control wiring, protective relaying, and SCADA/RTU/automation interfaces. - Working knowledge of IEEE, ANSI, NEC, and NESC standards. - Proficiency with Bluebeam (or equivalent) for redlines and markups. - Ability to travel to project and substation sites, some of which are not accessible by public transportation. **Preferred Qualifications** - Substation Design Suite (SDS) experience. - Exposure to procurement documentation and processes. - Engineer-in-Training (EIT) certification, with progress toward Professional Engineer (PE) licensure. ### Work Environment & Physical Demands This role combines office-based design work with periodic visits to substation and construction sites. This role may require: - Prolonged periods of sitting and working at a computer workstation, with or without reasonable accommodation - Periodic travel to substation and construction sites, some not accessible by public transportation - Site visits that may involve exposure to weather, energized electrical equipment, noise, and heavy equipment; appropriate PPE, including arc-rated clothing, must be worn on site - The ability to walk uneven terrain and access outdoor substation yards, with or without reasonable accommodation
