Semiconductor Product Engineer

Semiconductor Product Engineer Overview

Fractile is on a mission to revolutionize the hardware that powers advanced AI systems, aiming to enhance the speed and efficiency of output generation. We are currently looking for a skilled Semiconductor Product Engineer to join our team in Bristol. This role is pivotal in leading the development and implementation of manufacturing test solutions for our next-generation AI accelerator devices.

Key Responsibilities

• Define and develop testing methods and strategies for AI accelerator chips aimed at high-volume manufacturing.
• Plan and manage manufacturing test content for advanced CMOS designs, including high-speed logic, SRAM, DRAM, and high-speed IO blocks.
• Develop and debug structural and functional test content such as scan/ATPG, LBIST, MBIST, JTAG, and HSIO tests.
• Bring up first silicon on ATE, which includes pattern debugging, tester correlation, shmooing, and corner analysis.
• Support testing of high-speed interfaces like PCIe Gen6 and multi-GHz LPDDR, including at-speed tests and margining features.
• Execute silicon characterization and failure analysis to identify yield limiters and defect mechanisms.
• Optimize test coverage, test time, and cost while ensuring manufacturing robustness.
• Collaborate with DFT and design teams to enhance testability and address coverage gaps.
• Work with OSATs and external partners on the deployment of test programs.
• Support advanced packaging test flows, including die-to-die interconnect testing and package-level thermal considerations.
• Contribute to the documentation of test programs, debugging procedures, and manufacturing release materials.
• Assist in qualification, reliability testing, and the ramp-up of high-volume manufacturing.

Required Qualifications

• A minimum of 5 years of hands-on experience in semiconductor test engineering.
• Proven experience in developing ATE test programs using platforms such as Advantest 93K or Teradyne.
• Strong understanding of DFT methodologies including scan, ATPG, MBIST, and LBIST, as well as memory testing techniques.
• Experience in debugging silicon issues and correlating failures to design or process-related causes.
• Familiarity with advanced CMOS nodes and the challenges associated with production testing.
• Ability to effectively collaborate in a cross-functional engineering environment.

Preferred Qualifications

• Experience testing AI accelerators, GPUs, networking ASICs, or other high-performance compute ICs.
• Experience with PCIe Gen5/Gen6, LPDDR4/5/6, or other high-speed interfaces.
• Exposure to advanced packaging, chiplets, or multi-die test flows.
• Experience improving yield, reducing test time, or optimizing cost in high-volume manufacturing.

What We Offer

• Competitive salary that reflects experience and the specialized nature of the role.
• Equity opportunities to ensure all employees share in the value creation.
• Comprehensive benefits package including Private Medical, Dental, and Vision insurance.
• Contributory Pension plan.
• 25 days of holiday in addition to bank holidays.
• Life and Critical Illness Insurance.

Join us at Fractile as we strive to increase the clock speed of global progress, one chip at a time. We are committed to building a diverse and inclusive environment where the hardest problems are solved by the broadest range of minds.
