Custom Filters Direct information

What is Custom Filters Direct?

Custom Filters Direct is a company that specializes in manufacturing and supplying custom-sized air filters for residential, commercial, and industrial HVAC systems. They allow customers to order air filters in virtually any size, thickness, and type to fit their specific needs, which is particularly useful for non-standard or hard-to-find filter sizes. The company offers a variety of filter types, including pleated, fiberglass, and high-efficiency filters, and provides online ordering for convenience. Their products are designed to improve indoor air quality and maintain the efficiency of HVAC systems.

What are common challenges faced by employees at Custom Filters Direct, and how are they addressed?

Employees at Custom Filters Direct often encounter challenges related to managing custom orders and ensuring precise specifications for clients. Coordinating between production, sales, and logistics teams is key to meeting tight deadlines and maintaining product quality. The company typically addresses these challenges through regular team meetings, clear communication channels, and ongoing training to keep staff updated on the latest filtration technologies and customer service practices. This collaborative approach helps ensure that customer expectations are consistently met.

What is the difference between Custom Filters Direct vs HVAC Technician?

AspectCustom Filters DirectHVAC Technician
Required CredentialsNone specific, industry knowledge preferredEPA certification, technical training
Work EnvironmentOffice, warehouse, or remoteOn-site at buildings, HVAC systems
Employer & Industry UsageManufacturers, suppliers, online retailHeating, ventilation, air conditioning services
Search & Comparison IntentBuying filters, product infoRepair, installation, maintenance

Custom Filters Direct primarily focuses on selling and distributing filters directly to consumers and businesses, often through online channels. HVAC Technicians, on the other hand, are skilled professionals who install, repair, and maintain HVAC systems. While both roles are connected to air quality and climate control, their credentials, work environments, and industry functions differ significantly.

What skills and qualifications are needed to thrive as a Custom Filters Direct Sales Representative?

To thrive as a Custom Filters Direct Sales Representative, you need strong knowledge of HVAC filtration products, sales techniques, and experience in customer service, often supported by a high school diploma or relevant sales certifications. Familiarity with CRM systems, order processing software, and inventory management tools is typically required. Excellent communication, problem-solving, and relationship-building skills help you understand client needs and foster repeat business. These competencies ensure effective sales processes, customer satisfaction, and business growth in a competitive market.

Senior Photonics Test Systems Engineer

nEye.ai

Santa Clara, CA • On-site

$140K - $230K/yr

Full-time

Re-posted 11 days ago

Job description

About Us:
nEye.ai, a well-funded optical switch startup, is poised to revolutionize the future of data centers. nEye's MEMS-based silicon photonics optical circuit switches (OCS) eliminate critical bottlenecks in AI processing by enabling direct optical connections among thousands of GPUs and memory units. The company's SuperSwitch is an ultra-low power consumption, high radix, compact chip-scale design, offering hyperscale data centers enhanced performance, efficiency, and scalability.
Job Overview:
We are looking for a hands-on photonics experimentalist and test systems engineer to design, build, and scale the systems used to measure, validate, and productionize our optical platform.
This is not a traditional "test execution" role.
You will own how optical systems are measured, from first prototypes through high-volume production. This includes defining measurement strategies, building custom test systems, developing automation and analysis frameworks, and closing the loop between design, fabrication, and system performance.
Key Responsibilities
Build & Own Optical Test Systems
  • Architect and develop custom electro-optical test platforms at wafer, die, and module levels
  • Design and integrate instrumentation such as optical spectrum analyzers, tunable lasers, polarization control systems, and RF/electro-optical measurement setups
  • Build scalable, production-ready test racks and infrastructure
Drive Measurement Strategy & Insight
  • Define and validate key optical performance metrics (e.g., insertion loss, return loss, polarization-dependent loss, chromatic dispersion)
  • Develop novel measurement techniques and calibration methods where needed
  • Use DOE, statistical methods, and modeling to extract signal and guide design decisions
Bridge R&D to Manufacturing
  • Own the transition from lab validation to high-volume production test
  • Establish MSA, CpK, SPC, and yield monitoring frameworks
  • Support transfer of test systems to contract manufacturers and production partners
Close the Loop with Design
  • Collaborate with photonics, device, and systems engineers to identify performance limitations and failure modes
  • Debug complex issues across optical, electrical, and mechanical domains
  • Drive design improvements based on test data
Build Automation & Data Systems
  • Develop scalable test automation frameworks using Python, LabVIEW, or similar tools
  • Create data pipelines and analysis tools (e.g., JMP, MATLAB, Python)
  • Enable rapid debugging, visualization, and data-driven decision-making

Required Qualifications
  • Bachelor's or Master's degree in Optical Engineering, Electrical Engineering, Physics, or a related technical field
  • 6+ years of experience in photonics test, optical systems, or experimental optics
  • Hands-on experience building and debugging optical measurement systems (not just running tests)
  • Familiarity with telecom, datacenter optics, or silicon photonics systems
  • Experience with wafer-, die-, or module-level characterization
  • Experience building test systems from scratch and scaling them into production
  • Ability to bridge design, test, and manufacturing workflows
  • Background working with transceivers, PICs, modulators, lasers, or optical switching systems
  • Strong understanding of optical measurement physics
  • Experience with DOE, SPC, GRR, and yield optimization
  • Optical instrumentation: OSA, tunable lasers, OTDR/OFDR, VNA, BERT, polarization systems
  • Automation: Python (preferred), LabVIEW/TestStand
  • Data analysis: JMP, MATLAB, or similar tools

Preferred Qualification
  • Direct product experience testing specific components like DWDM filters, Mux/Demux, circulators, couplers, switches, etc.
  • Comfortable working in a high-velocity, evolving environment with a willingness to travel to support manufacturing partners and field deployment as required
  • Intimate knowledge of all of the following optical metrics and their measurement techniques: IL, RL, WDL, PDL, CD, DGD, GDR, and MPI

$140,000 - $230,000 a year
Expected Salary Range and Title: $140,000-$230,000 annually. Starting salary and title will depend on, and be commensurate with, relevant experience, skills, training, education, market demands, and the ultimate job duties and requirements.
nEye.ai is an Equal Opportunity Employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, age, sex, sexual orientation, gender identity, national origin, disability, protected veteran status, or any other characteristic protected by law.
