About AERINOX

AERINOX is a leading stationary-engine emissions control systems integrator, specializing in Selective Catalytic Reduction (SCR), Oxidation Catalyst (DOC), Diesel Particulate Filter (DPF), and integrated aftertreatment solutions for large diesel and natural gas engines ranging from 50 kW to 20 MW. With 800+ commissioned SCR installations, AERINOX is a trusted compliance partner for data centers, industrial operators, distributed power generators, and engine OEMs and dealers across North America.

Headquartered in Johnstown, Colorado, AERINOX operates as part of DCL — a broader emissions technology group with in-house catalyst formulation, custom fabrication, engineering, and global supply capabilities. Our value proposition goes beyond hardware: we deliver engineering, integration, installation, commissioning, and lifecycle support that enables customers to obtain permits and operate reliably in increasingly strict regulatory environments.

The Opportunity

We are growing our commercial team and seeking a driven, technically capable Sales Engineer to join us in Johnstown, Colorado. This is a relationship-first role focused primarily on managing and expanding existing accounts while capturing new sales opportunities across our key end markets: data centers/hyperscalers and industrial/distributed power customers.

You will be the primary commercial interface for a portfolio of accounts — understanding their permitting challenges, identifying expansion opportunities, and working closely with our engineering and project teams to deliver compliant, reliable emissions solutions. This role is ideal for someone who thrives at the intersection of technical problem-solving and long-term customer relationships.

What You’ll Do

- Own and develop a portfolio of existing customer accounts, serving as their primary point of contact for new projects and system upgrades

- Build deep relationships with permitting managers, facility engineers, operations leads, and procurement teams at data centers and industrial facilities

- Identify and pursue upsell and cross-sell opportunities including new system installations, replacement catalyst, controls upgrades, and service contracts

- Monitor customer regulatory environments and proactively engage when permitting requirements tighten or fleet expansions are planned

New Business Development

- Identify and qualify new capital equipment opportunities within target segments (data centers, distributed power, industrial)

- Develop and present technical proposals, system configurations, and ROI-driven value cases to engineering and operations stakeholders

- Coordinate with internal engineering and project management teams to ensure accurate scoping, pricing, and proposal delivery

- Attend industry events, trade shows, and customer site visits as needed (primarily virtual/remote selling with occasional travel)

Technical & Commercial Execution

- Develop a working understanding of SCR, DPF, DOC, and integrated aftertreatment systems to engage credibly with technically sophisticated buyers

- Communicate customer requirements clearly to internal engineering teams and serve as the voice of the customer throughout project execution

- Track pipeline, forecast accurately, and maintain CRM discipline

What We’re Looking For

Required

- 3–5 years of experience in a sales engineering, technical sales, or applications engineering role

- Background in industrial capital equipment, engineered systems, or related technical products

- Demonstrated ability to manage and grow complex B2B accounts with long sales cycles

- Strong written and verbal communication skills; able to present confidently to both technical and executive audiences

- Self-directed, organized, and comfortable operating in a lean, entrepreneurial environment

- Proficiency with CRM tools and standard business software

Preferred

- Experience in emissions control, environmental compliance, power generation, or adjacent industrial markets

- Familiarity with air permitting processes, non-attainment regulations, or environmental compliance requirements

- Experience selling to data centers, utilities, or large industrial operators

- Understanding of PLC-based controls or instrumentation systems

Compensation & Benefits

- Base salary: $85,000–$100,000 depending on experience

- Commission plan tied to new system/capital equipment sales

- Comprehensive benefits package including health, dental, vision, and 401k

- Collaborative team environment with direct access to senior leadership

- Opportunity to grow with a business at an exciting inflection point — expanding service offerings, controls capabilities, and installed base

This is an in-office position located at AERINOX headquarters in Johnstown, Colorado.
