Core Responsibilities

Primary Functions

Lead hands-on customer technical engagements from discovery through resolution, including on-site troubleshooting, lab reproduction of field issues, and delivery of technical recommendations that enable successful product integration and adoption.
Design and execute detailed hardware validation and characterization plans (electrical, thermal, mechanical, and RF as applicable) to verify product performance against specifications and document test data, procedures, and results.
Create and maintain reference designs, evaluation board schematics, and layout recommendations to accelerate customer development and reduce time-to-market for partner integrations.
Debug complex hardware and mixed-signal issues using oscilloscopes, logic analyzers, spectrum analyzers, network analyzers, thermal chambers, and power analyzers; perform root-cause analysis and propose design or firmware mitigations.
Develop and maintain automated test frameworks and scripts (LabVIEW, Python, PyTest, or similar) for regression testing, functional verification, and high-throughput manufacturing qualification.
Collaborate with firmware and embedded software teams to reproduce firmware-related performance issues, propose fixes, and validate firmware updates in the lab and field; participate in firmware bring-up and validation for new releases.
Provide pre-sales technical support and product demonstrations to customers and partners, including customizing demos, delivering technical presentations, and responding to RFP/RFI technical questions with clear, actionable materials.
Drive New Product Introduction (NPI) activities by coordinating cross-functional teams (hardware, firmware, test engineering, manufacturing, supply chain) to develop test plans, acceptance criteria, and production readiness checklists.
Author and maintain comprehensive application notes, integration guides, datasheet usage examples, test procedures, and troubleshooting documentation tailored to target customer use cases.
Analyze signal integrity and power distribution networks on PCBs; provide layout hygiene and decoupling recommendations to prevent EMI, noise coupling, and reliability issues in customer designs.
Define component selection criteria and provide recommendations on passives, power regulators, sensors, connectors, and RF modules to ensure optimal performance, cost, and manufacturability.
Drive reliability, stress, and environmental testing (thermal cycling, vibration, humidity, burn-in) and interpret results to advise engineering and product teams on necessary design changes or qualification steps.
Evaluate third-party modules and subsystems, run integration tests, and generate go/no-go recommendations to reduce integration risk and accelerate customer development cycles.
Support field escalation and warranty investigations by collecting telemetry, reproducing reported issues in the lab, preparing RCA reports, and coordinating corrective actions with design and manufacturing teams.
Mentor and train customers and internal stakeholders (sales, support, QA) through workshops, webinars, and technical enablement sessions to improve product knowledge and reduce time-to-first-success for integrations.
Collaborate with manufacturing and test engineering to create and optimize production test fixtures, automated test sequences, and pass/fail criteria that balance throughput with defect detection.
Maintain and operate advanced lab equipment, ensuring calibration, safety, and consistent test conditions; define and enforce lab best practices and test standards to generate reproducible results.
Provide input to product management on customer feature requests, prioritized bugs, and competitive product feedback to influence product roadmaps and hardware feature sets.
Perform cost-of-goods (COGS) and manufacturability reviews early in the development cycle to recommend design or component changes that improve yield and reduce unit cost without compromising product integrity.
Work closely with regulatory and compliance teams to plan and support EMC/EMI, safety, and radio certification activities; provide pre-compliance test data and corrective actions to meet target certifications.
Create and maintain a repository of test assets, example code, evaluation board BOMs, and reproducible test cases so engineers and customers can rapidly iterate and validate designs.
Monitor and analyze field performance data and telemetry to identify patterns, recurring failures, and opportunities for firmware or hardware updates that improve product reliability and customer satisfaction.
Coordinate cross-border or multi-site technical engagements, including travel to customer sites or contract manufacturers, to help with on-site commissioning, root cause investigations, or ramp support.

Secondary Functions

Support ad-hoc data requests for hardware performance metrics, exploratory analysis of failure rates, and trend reporting to inform reliability improvements.
Contribute to the organization's hardware strategy and roadmap by surfacing customer requirements and practical constraints observed during field engagements.
Collaborate with sales and marketing to produce technical collateral (whitepapers, case studies, bench guides) that highlight real-world application success stories and measurable benefits.
Participate in sprint planning and agile ceremonies within product and firmware teams to ensure customer-driven priorities are represented and deliverables are testable.
Assist with post-launch support tasks such as firmware patch validation, hardware revision reviews, ECO execution, and supplier change management.
Maintain lab inventory, test fixtures, and spare boards; manage procurement and staging of customer evaluation kits for demos and POCs.
Help develop training curricula and certification tracks for internal FAEs and channel partners to accelerate technical onboarding.
Support continuous improvement initiatives in test yield, cycle time, and defect reduction in collaboration with quality and manufacturing engineers.
Provide on-call support rotation for critical field incidents, including rapid triage, communication to stakeholders, and escalation management.
Participate in vendor and supplier technical evaluations to qualify components, modules, and manufacturing partners against defined application requirements.
