What problems you will solve:

Application Development & Method Optimization - Problems Solved:

• Lack of validated methods - Customers struggle without proven protocols, leading to failed experiments and wasted resources
• Platform incompatibility - Products that work in one system fail in another, causing customer frustration and returns
• Inconsistent results - Without optimized protocols, customers get variable data that can't support publications or regulatory submissions
• Time-consuming trial and error - Customers waste months developing methods that Filtrous could provide ready-to-use
• Regulatory rejection risk - Methods that don't meet specifications cause costly delays in clinical or diagnostic implementations

Customer Validation & Field Support - Problems Solved:

• Failed product adoption - Without on-site support, customers abandon products after initial failures rather than optimizing conditions
• Knowledge gaps - Many labs lack expertise in specialized techniques, preventing them from using advanced products effectively
• Site-specific variables - What works at Filtrous may fail at customer sites due to water quality, equipment differences, or user technique
• Extended downtime - Without rapid support, failed experiments can halt research projects or diagnostic testing for days/weeks
• Training bottlenecks - New staff can't get up to speed quickly, reducing lab productivity and increasing error rates

Content Creation & Marketing Support - Problems Solved:

• Underutilized products - Customers use products at 30% capability because they don't know advanced applications exist
• Lost sales opportunities - Sales team can't articulate technical value without compelling proof-of-performance data
• High support burden - Without clear documentation, every customer requires extensive hand-holding, overwhelming support staff
• Competitive disadvantage - Competitors with better technical content appear more credible and win customers despite inferior products
• Customer confusion - Complex scientific concepts presented poorly lead to misuse, complaints, and damaged reputation

Cross-functional Partnership - Problems Solved:

• Product-market misalignment - R&D develops products that don't fit customer workflows without field application input
• Sales credibility gaps - Sales team loses deals when they can't answer technical questions or demonstrate applications
• Post-launch failures - Products released without thorough application testing fail in customer hands, causing recalls/returns
• Compliance issues - Methods developed in isolation may not meet regulatory requirements, blocking customer implementations
• Siloed knowledge - Critical application insights stay trapped with individuals instead of improving products company-wide

Technology Evaluation & Market Intelligence - Problems Solved:

• Obsolete product portfolio - Missing emerging market trends leads to declining relevance and lost market share
• Blind competitive positioning - Without knowing competitor capabilities, can't effectively differentiate or price products
• Missed opportunities - Unaware of new application areas where existing products could excel with minor modifications
• Reactive product development - Always catching up to market needs instead of anticipating and leading
• Unsubstantiated claims - Without comparative data, marketing messages lack credibility and fail to convince customers

Qualifications:

• Ph.D. in Analytical Chemistry, Molecular Biology, Biochemistry, or related life sciences field with extensive experience in analytical instrumentation (required)
• Demonstrated expertise in method development and validation on analytical platforms including LCMS, HPLC, GCMS, ICP-MS, and qPCR systems
