Temporary Stem Cell Sales Jobs (NOW HIRING)

Turn Breakthrough Science into Real-World Solutions

Why This Role Matters
When a researcher's stem cell differentiation fails, months of work can be lost. When an antibody doesn't perform as expected, a clinical study stalls. At Filtrous, we don't just sell reagents and cell culture products. We help scientists succeed. As our Application Scientist in Biochemistry, you'll be the expert who bridges the gap between our products and real laboratory challenges. You'll develop validated protocols, travel to customer sites to solve problems firsthand, and create the technical content that helps scientists get results faster. Your work will directly impact research outcomes in cell therapy, diagnostics, and life science discovery.

What You'll Do
Turn Complex Techniques into Reproducible Success: Develop and validate cell culture protocols, stem cell differentiation methods, and immunoassays that customers can trust. You'll eliminate the trial-and-error that wastes their time and resources.
Be the Expert in the Field: Travel to customer sites to troubleshoot failed experiments, optimize antibody panels, and validate molecular assays. Your hands-on support turns frustrated customers into loyal partners.
Bridge the Knowledge Gap: Many labs lack expertise in advanced techniques like iPSC culture or multiplex immunoassays. You'll conduct training sessions that unlock capabilities they didn't know they had.
Create Content that Sells: Author application notes, white papers, and protocols that demonstrate product value. Your technical content becomes the proof that wins new customers.
Shape What We Build: Collaborate with R&D to ensure new products actually work in customer workflows. Your field insights prevent costly product-market mismatches.
Arm the Sales Team: Provide technical demonstrations and answer the hard questions during customer engagements. Your expertise closes deals that sales alone cannot.

Problems You Will Solve
Failed experiments waste months: When a customer's stem cell work or antibody test fails, weeks or months of effort are lost and clinical studies stall, with no expert on hand to step in and turn the failure around.
Trial-and-error slows customers down: Customers waste time and money figuring out cell culture and immunoassay products through guesswork because there are no validated, ready-to-use protocols they can simply follow and trust.
Labs lack advanced know-how: Many customers do not have the in-house skills for harder methods like specialized stem cell culture or multi-marker immune tests, so they leave product capabilities untapped with no one to train them.
Sales cannot answer hard questions: Deals stall when technical customers ask deep scientific questions during buying conversations, because the sales team cannot run demonstrations or close those discussions without expert backup.
New products miss real lab needs: Without real-world field feedback reaching the product team, Filtrous risks building products that do not fit how customers actually work, leading to costly mismatches.

How Success is Measured
Deliver 6+ validated protocols and technical application notes per quarter that customers can implement immediately
Achieve 90%+ customer satisfaction on field support visits and training sessions
Reduce product-related support tickets by providing clear documentation and proactive training
Contribute to new product launches with field-validated performance data

Why You'll Love It Here
At Filtrous, you're not buried in a corporate R&D lab running the same assay forever. You're a key player working closely with a small, collaborative team where your expertise directly impacts customers and products. You'll report directly to the Director of R&D, collaborate daily with sales, QC, and operations, and see your protocols used by real scientists solving real problems. You'll travel, meet customers, and build deep expertise across multiple applications. And as Filtrous grows, you'll grow with us: expanding into new product areas, mentoring future hires, and shaping our technical direction.

Who You Are
Ph.D. in Molecular Biology, Biochemistry, Cell Biology, or related field (required)
Hands-on expert in cell culture, stem cells, immunoassays, and molecular biology techniques
Proficient with key platforms: flow cytometry, qPCR, ELISA, Western blot, cell-based assays
Strong communicator: you can explain complex science to both PhDs and technicians
Customer-focused: you genuinely enjoy solving problems and helping scientists succeed
Willing to travel: customer sites, training sessions, and industry events
Bonus points if you have:
Experience with iPSC culture, stem cell differentiation, or cell therapy manufacturing
Background in antibody development, validation, or immunoassay optimization
Track record of published application notes or technical publications
Experience in clinical diagnostics or GMP/regulated environments
