About the role

Sales Representative: Pressure-Sensitive Adhesives and Tackifiers Full-time United States · Remote with travel Reports to: Business Development Director, Adhesives About Mstack Mstack is an R&D-led specialty chemicals platform that makes global sourcing simpler, more transparent, and more cost-effective. We operate across 15+ countries, are backed by Lightspeed Venture Partners and Alpha Wave Global, and have scaled past $150M in revenue. Our tech-enabled network of approved production facilities in strategic low-cost regions gives manufacturers access to high-performance materials without the usual tradeoffs on quality or lead time. The platform handles the full procurement cycle: sourcing, testing, shipping, and tracking. Every product moves through ISO and ASTM-certified testing before it ships. We serve CASE (coatings, adhesives, sealants, elastomers), oil and gas, water treatment, personal care, agrochemicals, and pharmaceuticals. Adhesives is one of our fastest-growing lines, and this role sits at the center of it.

About the Role: We are hiring a senior sales professional to build and run our pressure-sensitive adhesives business in North America. The scope covers both formulated PSA and hot melt adhesives and the raw materials that go into them, with tackifiers as a central part of the portfolio: C5 and C9 hydrocarbon resins, rosin esters, and terpene phenolics. You will own a book of business across converters, tape and label manufacturers, formulators, OEMs, and distributors, selling into packaging and graphics, labels, automotive, construction, and industrial markets. This is a hunting role with real technical content. Expect to sit alongside our product development and technical service teams through sampling, trials, and qualification.

What You Will Do: Build and manage a book of business across PSA and hot melt adhesive accounts, including the tackifier resins and other raw materials feeding those formulations Open new accounts with converters, formulators, OEMs, and distributors, and run the full cycle from first conversation through qualification and repeat volume Work cross-functionally with technical service and product development to support customer trials, sample qualification, and drop-in substitution work Partner with sourcing and QC to match customer specs to the right approved production facility, and to keep supply predictable once an account scales Represent Mstack at industry events such as PSTC Tape Summit, Label Expo Americas, and Foam Expo Feed market intelligence back to the business: competitive activity, pricing movement, supply shifts, and emerging applications

What We Are Looking For: 10+ years of sales experience in pressure-sensitive adhesives, hot melts, tackifiers, tapes, films, or label materials Working knowledge of tackifier chemistries (C5 and C9 hydrocarbon resins, rosin acids and rosin esters, terpene phenolics) and how resin selection shifts tack, peel, and shear performance Familiarity with PSA adhesive chemistries (acrylic, rubber-based, hot melt, silicone) and common substrates (paper, PET, PP, foam) Existing relationships with converters, distributors, formulators, or OEMs in adhesives or tape and label Comfort in technical sales conversations involving PSTC and ASTM test methods, bond performance, and application specs Willingness to travel roughly 30 to 50 percent for customer visits and trade shows Degree in chemistry, chemical engineering, or a related technical field is helpful but not required

Nice to Have: Experience selling globally sourced raw materials and walking customers through qualification of a new supply source Exposure to hot melt formulation for packaging, hygiene, or tape applications Distribution channel management, including pricing and program structure Why This Role Competitive base plus uncapped commission tied to what you close A supply chain, QC lab, and technical team behind you rather than a catalog and a price list Direct access to leadership and short decision cycles: if a deal needs a call on pricing or a new source qualified, you get an answer quickly Early ownership of a product line we are actively investing in Mstack is an equal opportunity employer. We evaluate every applicant on merit and do not discriminate on the basis of race, color, religion, sex, national origin, age, disability, veteran status, or any other protected characteristic.

Before you apply

Applying takes about a minute. These four things decide how fast it moves after that.

Your profile is current

It's what we read first. Occupations, seniority and locations matter more than a long history.

Two examples you can talk through

Not a portfolio — just two pieces of work where you can explain the decisions and what you'd change.

A number in mind

What you're on now and what would make you move. We negotiate better when we know both.

Your notice period

Employers plan around it, and it's the question that stalls offers most often.

Once you apply, someone reads it and calls you before anything reaches the employer — usually within two working days.
