🎯 Role Definition

The Instrument Designer is a multidisciplinary engineering role focused on designing, prototyping, validating, and supporting the manufacture of precision instruments (scientific, lab, medical, analytical, or industrial). This role blends mechanical, electrical, optical, and embedded systems design to translate user requirements into robust, manufacturable products. The Instrument Designer drives component selection, tolerance analysis, test planning, documentation, and regulatory/compliance activities while collaborating closely with R&D, firmware/software, manufacturing, quality, and product management.

Core Responsibilities

Primary Functions

  • Lead concept development and system-level design of precision instruments from requirements definition through prototype, verification, validation, and release to production, ensuring traceability to user needs and regulatory constraints.
  • Create and maintain detailed 3D CAD models, assemblies, and production drawings (SolidWorks/Creo), including GD&T, tolerance stacks, and material specifications for manufacturability and cost targets.
  • Design, specify, and integrate electronic subsystems and PCBs in coordination with electrical engineering (schematic review, component selection, power distribution, signal integrity, EMC considerations).
  • Develop embedded firmware interfaces and collaborate with firmware/software engineers to ensure timing, communications, sensors, and actuators meet system requirements; contribute to firmware architecture and low-level debugging when required.
  • Architect optical and sensor subsystems (lens selection, alignment features, detector integration, stray light mitigation) for analytical and imaging instruments, including optical tolerance analyses and simulation.
  • Define and execute prototype builds, including hands-on assembly, lab testing, iterative refinement, and rapid iteration to reduce technical risk and accelerate time-to-first-prototype.
  • Create detailed test plans, verification protocols, and validation test matrices to demonstrate conformance to functional, environmental, EMC, safety, and regulatory requirements.
  • Lead failure modes and effects analysis (DFMEA/FMEA) and root cause analysis for design robustness, reliability improvements, and risk mitigation strategies throughout product development.
  • Develop calibration procedures, verification jigs, and automated test fixtures for production and field calibration; define calibration frequency and traceability requirements.
  • Generate bills of materials (BOM), routings, costed part lists, and supplier specifications; evaluate vendor capabilities, source critical components, and support supplier qualification and negotiations.
  • Prepare and maintain technical documentation including specifications, assembly instructions, work instructions, service manuals, and design history files to support manufacturing and regulatory audits.
  • Collaborate with quality and regulatory teams to ensure compliance to relevant standards (e.g., ISO 9001, ISO 13485, CE, RoHS, FCC, UL), and support submission packages for regulatory approvals when required.
  • Drive DFM/DFM reviews with manufacturing and operations to optimize part design, simplify assembly, reduce cost, and identify process control requirements prior to production release.
  • Plan and execute environmental and reliability testing: thermal cycling, humidity, vibration, shock, ingress protection (IP), and long-term performance testing to establish product lifetime and warranty metrics.
  • Perform tolerance analysis and mechanical stress analysis (FEA) to ensure structural integrity, thermal stability, and dimensional control under operating conditions.
  • Design and debug harnesses, cable assemblies, connectors, enclosures, and EMI shielding solutions to maintain signal fidelity and product safety in final form-factor.
  • Provide field support and in-service troubleshooting for early product deployments, performing on-site diagnostics, corrective design changes, and firmware updates as needed.
  • Manage project schedules, technical budgets, and milestone deliveries while communicating progress and technical trade-offs to product management and stakeholders.
  • Mentor junior designers and technicians, conduct design reviews, and enforce best practices for CAD model management, version control, and change control (ECO process).
  • Coordinate cross-functional engineering reviews (concept, preliminary, critical, production readiness) and ensure design closure with actionable verification evidence.
  • Implement quality by design: design verification testing, statistical analysis of manufacturing data, and continuous improvement initiatives based on field feedback and warranty data.
  • Support intellectual property strategy by documenting novel design concepts, contributing to patent disclosures, and participating in prior-art assessments.

Secondary Functions

  • Assist product marketing and applications teams with technical content for datasheets, whitepapers, and launch collateral that accurately describe instrument capabilities and limitations.
  • Support sales and field teams with application engineering, specimen testing, and customer-focused demonstrations during pre-sales and pilot programs.
  • Maintain and calibrate lab test equipment and instrumentation used in R&D and validation efforts; schedule and document calibration activities.
  • Participate in continuous improvement programs to reduce time-to-market, increase yield, and improve serviceability of instruments.
  • Help define component lifecycle plans and obsolescence mitigation strategies to ensure long-term product support.
  • Lead small cross-functional technical task forces to rapidly address high-priority field issues or urgent product changes.
  • Support sustainability and materials selection initiatives to meet environmental and regulatory goals (RoHS, REACH) and reduce product environmental impact.
