Fractile is building silicon, systems and software which will redefine the frontier of AI: running the world’s most advanced models at radically higher speed and lower cost. We have an exceptional team across hardware and software capable of bringing about this change, and we are growing fast to meet demand and deliver our product at scale.
As a fabless company, manufacturing excellence is achieved through deep technical collaboration and influence across external partners.
The Role
We are seeking aStaff Foundry Technical Managerto serve as Fractile’s technical representative at our Taiwan-based foundry partners.
This is a highly technical, hands‑on individual contributor role focused on:
* Yield ramp acceleration
* Parametric performance tracking
* Process integration alignment
* Manufacturing risk mitigation
You will not “run a fab” — instead, you will drive outcomes through technical depth, data analysis, influence, and structured collaboration with foundry engineering teams.
This role requires someone who understands how to extract maximum performance and yield from an advanced-node process in a fabless operating model.
What You’ll Own
Foundry Technical Interface (Fabless Model)
* Act as Fractile’s on‑the‑ground technical representative with the foundry.
* Engage directly with foundry teams across process integration, yield, device, lithography, and reliability.
* Translate foundry process data into actionable insights for internal design and product teams.
* Drive issue resolution without direct manufacturing authority — through technical rigor and relationship strength.
Yield Ramp & Learning Acceleration
* Lead yield analysis from first silicon through high‑volume production.
* Analyze inline, WAT, parametric, and defect density data.
* Identify yield limiters and systemic process sensitivities.
* Drive structured root cause analysis (RCA) with the foundry.
* Shorten yield learning cycles and reduce ramp time.
* Evaluate process change notices (PCNs) and assess design impact.
* Identify node‑specific variability and reliability risks.
* Support qualification, reliability stress analysis, and lifetime modeling.
Cross‑Functional Alignment
* Collaborate closely with:
* Physical Design & Implementation
* OSAT & Packaging partners
* Provide structured technical updates to leadership.
* Help define manufacturing readiness and tape‑out criteria for future programs.
What We’re Looking For
* 5+ years in semiconductor process integration, yield engineering, or foundry‑facing roles.
* Direct experience working with Taiwan‑based foundries.
* Advanced node experience (≤7nm strongly preferred).
* Deep knowledge of:
* CMOS process integration
* Yield learning methodologies
* Parametric analysis & variability
* Defect density modeling
* Experience supporting at least one advanced‑node product from first silicon to volume ramp.
* Strong analytical and data‑driven mindset.
* Ability to influence without formal authority in a fabless model.
* Fluent in English; Mandarin strongly preferred.
Ideal Candidate
You are:
* Technically authoritative yet collaborative
* Comfortable operating inside external partner ecosystems
* Highly data‑driven and structured in problem solving
* Calm under yield excursion or ramp pressure
* Motivated by building category‑defining AI silicon in a startup environment
You understand that in a fabless company, success depends on:
* Technical credibility
* Precision in communication
* Speed of analysis
* Strong engineering relationships
Why This Role Is Critical at Fractile
As a fabless company building advanced AI silicon, Fractile’s success depends on how effectively we collaborate with and influence our manufacturing partners.
In this role, you directly impact:
* Performance targets
* Yield ramp speed
This is a high‑leverage technical leadership role at the centre of Fractile’s path to production scale.
About us
* Founded in 2022, team of 70+, which is expanding rapidly
* Modern, open offices in London and Bristol
* Collaborative, problem‑solving culture built on deep curiosity, entrepreneurial initiative and technical fluency
