What are the responsibilities and job description for the Sales Engineer Controls & Automation position at Growlink?
About Growlink
Growlink builds the control systems that power the most advanced commercial cultivation facilities in the world — automating HVAC, lighting, irrigation, and fertigation so growers can focus on yield, consistency, and efficiency. We're a fast-moving team where every system we ship has a real-world impact on how food and cannabis is grown at scale.
The Role
We're looking for a Senior Sales Engineer who can do two things exceptionally well: partner with our Account Executives to win complex deals, and own the technical scope of those projects from discovery through production-ready handoff.
This is an equal split between sales-facing and engineering work. Half your time you'll be the technical expert in the room — on discovery calls, demos, and customer presentations — helping AEs build confidence and close deals. The other half you'll be heads-down: reviewing MEP and irrigation plans, designing control architectures, specifying hardware, and ensuring every BOM and drawing set is accurate and build-ready before it touches the shop floor.
If you love being the person who bridges the gap between what a customer needs and what actually gets built — this role was designed for you.
What You'll Do
Sales & Customer Engagement (50%)
- Join Account Executives on discovery calls, technical presentations, and solution design sessions as the subject matter expert on controls and automation
- Lead technical alignment conversations with customers and project stakeholders — translating complex requirements into clear, confident solutions
- Build customer trust by acting as a credible technical advisor who understands both operational goals and financial constraints
- Support proposal development, system scoping, and quoting alongside the sales team
- Help AEs identify gaps, risks, and opportunities in a project scope before they become problems
Technical Design & Engineering (50%)
- Review Architectural, MEP, and Irrigation plans to define integration strategies for each project
- Design control system architectures using low-voltage controls and industrial protocols (BACnet, Modbus) across HVAC, lighting, irrigation, and environmental systems
- Specify controls hardware and develop layouts for UL 508A control panels, including transformer/power supply sizing, I/O allocation, and circuit protection
- Size and specify fertigation systems — water flow rates, pipe sizing, tank volumes, and nutrient injection
- Validate all designs against customer requirements, equipment specs, and real-world constraints
- Finalize drawing sets, BOMs, and submittals — and work directly with panel drafters to ensure accuracy and build readiness before release to production
- Coordinate with panel shops, equipment vendors, and internal teams to keep projects on track
What We're Looking For
Required
- 5–10 years in controls engineering, industrial automation, or building automation systems (BAS)
- Strong ability to read and interpret MEP drawings and technical submittals
- Hands-on experience with low-voltage controls and protocols (BACnet, Modbus)
- Proven experience designing electrical control panels and systems
- Comfortable in customer-facing settings — you can explain complex systems clearly to both engineers and non-technical stakeholders
- Able to translate customer requirements into build-ready designs with minimal rework
Preferred
- Experience in cannabis, greenhouse, or controlled environment agriculture (CEA)
- Background in fertigation and irrigation system design
- PLC/BAS programming experience
- Familiarity with UL 508A standards and panel production workflows
- Comfortable with advanced Excel or system design tools
What Success Looks Like
- AEs feel equipped and confident going into technical conversations because you're in their corner
- Customers leave discovery calls with a clear understanding of the solution and high confidence in Growlink's expertise
- Designs are production-ready with minimal rework — scoped right the first time
- Sales, engineering, and production are tightly aligned on every project
- Projects move efficiently from design through commissioning
Why Growlink
You'll work on systems that directly impact how the world's most sophisticated cultivation facilities operate. This isn't theoretical — your designs get built, commissioned, and run in real facilities. You'll have real ownership, a close-knit team, and the opportunity to shape how we scale.
