About this role

What you'll own

- Mythic’s end-to-end production test strategy across Wafer Sort, Final Package Test, characterization, screening, and volume ramp

- Test programs for new silicon products, from development and debug through production release and optimization

- Test methodology, coverage strategy, screening philosophy, and release criteria

- Silicon bring-up, characterization, correlation, guardbanding, and test transfer into manufacturing

- Yield and quality analysis: finding systematic failures and escapes and driving them to root cause

- Day-to-day technical work with OSATs, foundries, and ATE vendors to deploy and sustain test flows

- Tradeoffs across test coverage, cost, test time, quality, and ramp schedule

- Infrastructure, automation, and analytics for production test and yield learning

What you'll bring

Required qualification

- 5+ years in semiconductor test engineering, product engineering, or production test development

- Hands-on ownership of Wafer Sort and Final Package Test

- Developing, debugging, and releasing test programs on ATE platforms in production

- Converting and translating test patterns from STIL, WGL, and VCD into ATE-specific pattern formats

- Solid grounding in manufacturing test flows, device screening, test coverage, guardbanding, and outgoing quality

- Experience taking silicon through bring-up, characterization, yield ramp, and production release

- Strong debug skills and fluency with manufacturing test data

- Experience working with design, DFT, product, reliability, and operations teams

Preferred qualifications

- Testing mixed-signal or analog silicon, including trim and calibration

- Experience with AI, accelerator, or high-performance compute silicon

- Experience with Advantest, Teradyne, or similar ATE platforms

- Probe cards, load boards, hardware interfaces, and test hardware debug

- DFT structures such as scan, MBIST, and boundary scan

- Managing OSATs and other external manufacturing partners

- Scripting, automation, and test-data analysis (e.g., Python, JMP, or yield-analysis tools)

- A track record of reducing test time and improving yield and correlation during ramp

What success looks like in your first year

- Wafer Sort and Final Test flows are robust, scalable, and released to production

- New products move from bring-up to manufacturing with strong coverage and few surprises

- Yield issues are caught early and driven to root cause quickly

- Test programs are stable, efficient, and built to scale with volume

When determining compensation, a number of factors will be considered, including skills, experience, job scope, location, and competitive compensation market data.
