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.
Fractile is building next-generation AI compute infrastructure designed to dramatically improve performance-per-watt and unlock new efficiency frontiers for large-scale inference. Our hardware pushes the boundaries of high-speed design, power density, and system integration. We are looking for a PCBA Product Engineer to help industrialise our advanced AI accelerator boards and scale production with world-class manufacturing partners in Taiwan. This is a critical, high-ownership role at the core of our hardware execution strategy.
You will take complex, high-performance PCBAs from prototype through mass production — working at the intersection of hardware design, manufacturing engineering, and supplier execution. This role requires deep experience with:
- High-layer-count, high-speed boards
- Advanced PCB stackups
- Fine-pitch BGA assembly
- Taiwan-based PCB fabs and SMT partners
You will not only execute builds — you will shape how Fractile scales hardware manufacturing.
What You’ll Do
- Lead DFM / DFA / DFT reviews for high-speed AI accelerator boards.
- Partner with design engineering to proactively eliminate manufacturability risk.
- Support board bring-up and rapid iteration cycles.
- Work Closely with Taiwan Manufacturing Partners.
- Validate SMT process windows for fine-pitch, high-thermal-mass components.
- Be physically present during builds to drive real-time issue resolution.
- Ensure strong process control and ramp readiness.
- Own Yield and Quality Metrics.
- Drive first-pass yield (FPY) and DPPM improvements.
- Lead structured root cause analysis (8D, RCCA).
- Support reliability validation (thermal cycling, power cycling, environmental stress).
- Build Scalable Manufacturing Systems.
- Establish documentation, control plans, and ECO processes appropriate for a scaling startup.
- Improve traceability and production data visibility.
- Partner with supply chain on cost-down and second-source strategy.
What We’re Looking For
Required Experience
- 5+ years in PCBA Product Engineering, NPI, or Manufacturing Engineering.
- Experience industrialising complex, high-density PCBAs.
- Strong knowledge of:
- 12+ layer stackups
- Controlled impedance
- Fine-pitch BGA assembly
- High-power board considerations
- Hands-on factory experience with Taiwan PCB fabs and SMT partners.
- Fluent Mandarin and English.
Strongly Preferred
- Experience with AI accelerators, GPUs, server boards, or high-performance compute.
- Exposure to high-speed interfaces (PCIe, DDR, high-current rails).
- Experience scaling from prototype to volume production.
- Startup or fast-growth hardware environment experience.
Who You Are
- You take full ownership of outcomes, not just tasks.
- You are comfortable on the factory floor solving problems in real time.
- You think systematically but move quickly.
- You identify risks before they become production issues.
- You thrive in high-performance, technically rigorous environments.
What Success Looks Like at Fractile
- Smooth NPI transitions with minimal yield loss.
- Strong first-pass yield at ramp.
- Reduced DFM escapes before production freeze.
- Tight collaboration between design and manufacturing.
- Manufacturing processes that scale as Fractile scales.
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.
