Job description

Job Overview

The Account Executive, Industrial is a high-stakes hunter who thrives on strategic target accounts. You aren’t just selling hardware; you are architecting future-state energy solutions for sophisticated stakeholders in the Oil & Gas and Heavy Industrial sectors. You will take the baton from our leadership team to own the full sales cycle—from initial latent interest to executed multi-million dollar contracts.

Core Responsibilities

• Execute the Target Account Strategy: Own and manage a concentrated portfolio of strategic target accounts, executing on plans to nurture relationships and create repeatable buyers
• Contract Execution: Drive the "last mile" of the sales process. You are responsible for moving deals from "Progress" to "Closed-Won" and meeting annual quota targets
• Relationship Architecture: Build deep, lasting trust with technical champions and C-suite executives, ensuring Mainspring is the preferred partner for long-term energy infrastructure
• Technical Value Selling: Articulate the complex value proposition of our linear generator, including project finance concepts (IRR, NPV) and technical hardware integration
• Cross-Functional Collaboration: Partner with engineering and business development to feed market intelligence back into our product roadmap

Qualifications

• Experience: 14+ years of experience transacting complex, high-TCV enterprise deals in the energy or heavy industrial space (e.g., Distributed Power Generation, Midstream, Energy Infrastructure, Capital Equipment)
• Vertical Fluency: Deep domain expertise in Oil & Gas—Midstream or Energy Transition arms of integrated Majors preferred
• Proven Enterprise Closer: Track record of originating, negotiating, and closing complex hardware/infrastructure deals. (Not a pure BD strategy role—requires direct contract closing experience)
• Startup Grit: Ability to thrive in fast-paced, high-growth environments; comfortable building a brand’s presence from the ground up without massive corporate support structures
• Technical Literacy: Ability to master the nuances of distributed power hardware, gas blending/fuel flexibility (Natural Gas, Field Gas, Propane, RNG, Hydrogen), and grid interconnection constraints
• Education: Bachelor’s degree in Engineering, Business, or Finance required; MBA or advanced degree preferred
