Sr. Manufacturing Test Engineer

Etched is building AI chips that are hard-coded for individual model architectures. Our first product (Sohu) only supports transformers, but has an order of magnitude more throughput and lower latency than a B200. With Etched ASICs, you can build products that would be impossible with GPUs, like real-time video generation models and extremely deep & parallel chain-of-thought reasoning agents.

Job Summary

Etched is hiring a Senior Manufacturing Test Engineer based in Taiwan to own development, deployment, and sustainment of manufacturing test solutions at our L10 contract manufacturer. You will serve as the primary in-region technical lead for test strategy and execution, ensuring robust and scalable test processes across PCBA, subsystems, and full server-level builds. This role requires deep technical expertise and hands-on engagement with CM partners to ensure high yield, quality, and reliability as we ramp into production.

Key Responsibilities

• Develop and validate manufacturing test plans, fixtures, and automated test systems across board, subsystem, and server levels.

• Collaborate with design, packaging, and reliability engineering to define test requirements and ensure sufficient coverage.

• Ensure test infrastructure readiness to support production ramp.

• Qualify test process readiness at CM to ensure sufficient test coverage and optimized test time.

• Monitor test metrics including yield, throughput, and false failure rates; drive continuous improvement.

• Lead root cause analysis and corrective action for test escapes, yield issues, and reliability failures.

• Partner with CM engineering teams on NPI builds, MP ramps, and process change control.

• Provide DFT (Design for Testability) feedback to internal design teams for next-generation products.

• Ensure test solutions are scalable, maintainable, and compliant with reliability and quality standards.

• Act as the primary technical interface for all test-related topics between Etched HQ and L10 in Taiwan.

You may be a good fit if you have:

• Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, or related field.

• 7 years of experience in manufacturing test engineering for complex hardware systems (servers, networking, or semiconductor-based).

• Strong background in test development for PCBA, HBM/memory, power delivery, and system-level validation.

• Proficiency in automated test systems, scripting (Python, LabVIEW, or similar), and test data analysis.

• Hands-on experience with ICT, functional test, and high-volume test strategy.

• Prior experience working directly with Taiwan-based contract manufacturers (L10-level preferred).

• Fluent in Mandarin and English, with strong communication and technical documentation skills.

• Ability to travel within Taiwan and occasionally internationally.

Strong candidates may also have:

• Experience supporting NPI to MP ramp in AI ASIC or high-performance server systems.

• Familiarity with HBM memory test, probe card design, and socket qualification.

• Prior exposure to reliability testing and failure analysis workflows.

• Background in startup or hypergrowth hardware environments with high ownership.

How we're different

Etched believes in the Bitter Lesson. We think most of the progress in the AI field has come from using more FLOPs to train and run models, and the best way to get more FLOPs is to build model-specific hardware. Larger and larger training runs encourage companies to consolidate around fewer model architectures, which creates a market for single-model ASICs.

We are a fully in-person team in San Jose and Taiwan, and greatly value engineering skills. We do not have boundaries between engineering and research, and we expect all of our technical staff to contribute to both as needed.
