About the role

Are you a systems-level thinker who thrives on untangling complex hardware mysteries?
Do you prefer the thrill of deeply investigating and solving structured, multi-domain problems over routine schematic drafting?
Mainspring Energy is looking for a highly autonomous, intellectually curious Senior Electrical Systems & Sustaining Engineer to anchor a brand-new sub-team within our Electrical Engineering (EE) organization.

Responsibilities

Utilize standard laboratory diagnostic equipment (oscilloscopes, digital multimeters, power supplies, logic analyzers, and electronic loads) to validate containment strategies and prove out root-cause theories
Root Cause & Failure Analysis: Lead end-to-end problem resolution spanning from initial telemetry data parsing to deep-dive root cause analysis.
Partner closely with our internal Failure Analysis (FA) experts to diagnose complex electronics and hardware system failures
Design Ownership for Reliability: Directly drive the continuous improvement of our deployed hardware ecosystem.
You will have the technical authority to own and execute the engineering change lifecycle-from designing and releasing targeted PCBA revisions to identifying, testing, and qualifying strategic off-the-shelf (OTS) components-to permanently eliminate failure modes and improve system performance
Technical Triage & Strategy: Function as the primary gatekeeper for incoming electrical engineering challenges. For specialized issues, triage, prioritize, and collaboratively map out resolution strategies with design specialists across the EE department
Metrics & Infrastructure Management: Own and optimize the EE Atlassian/Jira Problem dashboard.

Requirements

8+ years of experience with a Bachelor's degree, or 4+ years of experience with a Master's degree, in Electrical Engineering or a related field.
Technical Acumen: Strong foundational expertise in complex electronics and hardware systems (preference for broad mechatronics/electronics experience over purely facility power systems)
Hands-on Lab Experience: Proven competency in a physical hardware lab environment setting up test benches, instrumenting hardware under test, and maintaining clean, safe laboratory testing practices
You are not satisfied with the first layer of failure and have a tenacity towards finding the true root cause
Systems-Level Perspective: The ability to zoom out and understand complex interdependencies across circuitry, firmware, manufacturing and mechanical wear mechanisms within a massive multi-domain machine
The ability to zoom out and understand complex interdependencies across circuitry, firmware, manufacturing and mechanical wear mechanisms within a massive multi-domain machine
Familiarity with the Python for data parsing, automated test script creation, or querying hardware telemetry logs
You will turn deep-dive technical findings into institutional knowledge, creating the foundational documentation required to scale this sub-team and uplevel the broader engineering organization
8+ years of experience with a Bachelor's degree, or 4+ years of experience with a Master's degree, in Electrical Engineering or a related field. This background must be in an Electrical, Product, or Reliability Engineering capacity with a clear track record of owning complex circuit/schematic analysis, physics-based root-cause investigations, and the full engineering change (EC) design lifecycle

Nice to have

Process Discipline & Tools: Prior experience working within formal CAPA structures, quality management frameworks, and bug/incident tracking ecosystems (e.g., Jira, Confluence)
Fast-Paced Environments: Prior experience working within a startup, rapid product development environment, or a scaling hardware company where agility and self-direction are mandatory
ECAD Tools: Proficiency with professional ECAD software layout and schematic design tools, preferably Altium Designer
Software & Scripting: Familiarity with the Python for data parsing, automated test script creation, or querying hardware telemetry logs
Modern Version Control: Experience utilizing Git-based version control workflows ( GitHub or GitLab ) for tracking hardware code, scripts, or engineering documentation
