Country: USA Summary

We are seeking a high-caliber Senior Systems Engineer & Engineering Team Lead to define our technical foundation, architect our next-generation power solutions, and lead our multi-disciplinary engineering design team.
In this pivotal role, you will own the end-to-end systems engineering lifecycle—bridging the gap between product management requirements and physical engineering execution. You will drive the architecture of our multi-MW modular infrastructure, up to Medium Voltage (MV), ensuring our modular solutions are safe, highly resilient, and optimized for rapid deployment.

Key Responsibilities
1. Technical Leadership & Team Management
  • Lead a Multidisciplinary Team: Direct, mentor, and build a high-performing design team consisting of electrical, mechanical, and controls/software engineers.
  • Engineering Governance: Establish robust engineering workflows, design standards, and enforce peer-review processes to ensure institutional quality and safety.
  • Resource & Project Coordination: Collaborate with Project Management to assign engineering resources, manage design schedule, and achieve timely product deliverables.
2. Systems Engineering & Architecture Definition
  • Requirements Ownership: Translate high-level market requirements (MRDs) into rigorous, traceable system-level technical requirements, functional specifications, and interface control documents (ICDs).
  • System-Level Architecture: Oversee the architecture and development of robust 3-phase electrical power distribution systems. Define the electrical, mechanical, thermal, and logical boundaries and interfaces.
  • Verification & Validation (V&V): Formulate comprehensive verification matrices, Factory Acceptance Testing (FAT) protocols, and field commissioning guidelines to validate system performance.
3. Electrical Power Systems Engineering
  • Critical Component Integration: Evaluate, specify, and select heavy electrical subsystems including high-capacity double-conversion UPS systems, static transfer switches (STS), switch gear, protective relays, and other critical subsystems.
  • Engineering Studies: Direct and review system modeling analyses, including short-circuit, protective relay coordination, arc flash, and harmonic mitigation studies.
  • Compliance Alignment: Ensure all system architectures natively comply with industry-defining standards (e.g., UL 9540A for BESS, UL 891/1558 for switch gear, NFPA 70/70E, and CE/IEC equivalents).
  • DFX (Design for X): Partner with manufacturing and service teams to optimize designs for manufacturability, transportability, and fast field installation.
Technical Expertise & Methodologies
  • Power Systems: Expert-level mastery of 3-phase AC/DC power systems, MV/LV power conversion topologies, utility protection schemes, and grounding methods.
  • Systems Engineering: Hands-on experience with systems engineering frameworks, specifically boundary diagrams, failure mode and effects analysis (FMEA), and requirements traceability matrices.
  • Grid Connection: Strong familiarity with utility interconnection requirements and power quality standards.
Tools & Software
  • Electrical Modeling: Proficiency with industry-standard simulation software (e.g., ETAP, SKM Power Tools, or Easy Power).
  • Systems & Design Tools: Familiarity with PLM software, requirements management tools, and CAD collaboration workflows (e.g., Solid Works/AutoCAD Electrical).
Physical Demands
  • Duties of this position are performed in a normal office environment.
  • Duties may require extended periods of sitting and sustained visual concentration on a computer monitor or on numbers and other detailed data.
  • Repetitive manual movements (e.g., data entry, using a computer mouse, using a calculator, etc.) are frequently required.
