Nanogrid Electro‑Mechanical Build Technician

Organization: Sesame Solar

Job Type: Full-time (Part-time available)

Position Level: Junior & Senior Levels

Compensation: $20.00 – $30.00 per hour

• Junior range: $20.00 – $24.00/hr, based on foundational experience
• Senior range: $25.00 – $30.00/hr, reflecting leadership and specialized technical depth

A day in the shop

It’s 7:30 AM in Jackson, MI. You join a tight-knit build crew, review schematics with engineering, and roll a mobile Nanogrid onto the floor. By mid-morning, you’re either laying precise welds and assembling structural components—or routing harnesses, landing conductors, and validating controls. After lunch, you’re troubleshooting a system quirk, dialing in a finish that looks as good as it performs, and mentoring a teammate on a new tool. Every unit you touch helps communities access resilient, renewable power.

Choose your build path

We hire across two tracks and place you as Junior or Senior based on your strengths.

Track 1: Fabrication, Assembly & Finishing

• Execute mechanical implementation: trailer fabrication, structural welding, precision mechanical assembly, and preventive maintenance.
• Apply expert metalworking and woodworking practices using welders, grinders, cutters, drills, and forming tools to craft durable components.
• Deliver high‑quality finishes, including painting and protective coatings for long‑lasting, professional results.
• Suggest practical improvements to designs, build methods, and finishing processes.

Track 2: Electrical & Power Systems

• Integrate low‑voltage DC (12V/24V/48V), 120/240V single‑phase AC, and high‑power 3‑phase AC for off‑grid and grid‑tied operation.
• Assemble and wire solar PV, battery energy storage systems (BESS), and hydrogen components.
• Install and configure inverters and power conversion modules.
• Install, test, maintain, and troubleshoot wiring, controls, and instrumentation within each Nanogrid.

What everyone on the team does

• Collaborate: Partner with the Production Manager and engineers to build, refine processes, and boost efficiency.
• Diagnose & repair: Track down mechanical or electrical issues and implement lasting fixes.
• Assure quality: Inspect parts and finished units to meet exacting performance standards.
• Work safely: Keep a clean, organized station and follow all safety procedures.
• Lead at senior level: Own complex builds, optimize equipment settings, and train/mentor junior teammates on tools, welding, machinery, and test instruments.

Qualifications

Education & experience

• Technical degree, trade school, or equivalent hands‑on background in mechanical or electrical disciplines.
• Junior: 1–4 years (or comparable apprenticeship/training) in metal fabrication, mechanical assembly, finishing, or electrical assembly.
• Senior: 5–10+ years in metal fabrication/finishing (e.g., RV, trailer, modular) and/or industrial electrical assembly (including 3‑phase, off‑grid/grid‑connected) within manufacturing.

Core capabilities (must have)

• Demonstrated skill in either mechanical fabrication/assembly or electrical power systems.
• Comfort reading blueprints, engineering drawings, and electrical schematics.
• Safe, proficient use of fabrication tools (welders, power tools) or electrical test/diagnostic equipment.
• Strong craftsmanship, troubleshooting ability, attention to detail, and quality mindset.
• Clear communication and team orientation; able to work independently and collaboratively.

Trainable/Preferred

We provide on‑the‑job training; you’re not expected to arrive with every specialty.

• Mobile/modular customization (trailers, RVs, shipping containers)
• Renewable components such as solar array integration and advanced battery storage configurations

Physical & operational

• Lift up to 40 lbs, stand for extended periods, and operate a forklift safely.
• Ability to reliably commute to, or relocate to, Jackson, MI 49201 before starting (Required).

Schedule, culture & benefits
