## Job description

Diamond Foundry Inc. is solving the thermal limitation at the foundation of today's most exciting tech industries -- AI & cloud compute, electric-car power electronics, and 5G/6G wireless. We have managed to produce the world's first single-crystal diamond wafers and are now on a mission to put a diamond behind every chip. We are the rare unicorn that has grown fast and profitably. We received $515m in funding and are executing a multi-$B expansion plan for one of the greenest forms of tech manufacturing: converting greenhouse gas into diamond wafers using zero-emission energy.

We are seeking an ambitious, skilled, and versatile Senior Metrology Engineer. In this position, you will play a key role in the development and implementation of measurement systems combining physical dimensions determination and defect detection. You will develop and maintain computer vision models for tracking sample defects at various stages of the process. You will also develop 3D measurement capabilities for samples of various sizes and shapes. Based in Zaragoza, you will be an integral part of an experienced team of mechanical, electrical, and materials engineers, and at the interface between R&D, process, and production operations across our various facilities. The position will involve hardware design, data collection, deep learning model training and evaluation, development of post-processing scripts, and data analysis.

## Responsibilities

- Development of routines for 3D measurements and extraction of form, dimensions, surface roughness/flatness.
- Development, testing, and maintenance of deep learning vision models.
- Developing tools for monitoring model performance and data integrity.
- Effectively communicating results and recommending a course of action.
- Acting as a point of contact between the metrology team and the process and production teams to define requirements and metrics. You will also partner with vendors to evaluate new optical/vision characterization equipment and technologies, upgrade existing tools, and expand capacity/throughput.

## Requirements

- Bachelor's degree with 2+ years of relevant experience in Mathematics, Computer Science, Physics, Material Science, Engineering, or a similar field.
- Fluency in Python and machine learning libraries (ex. sklearn), including experience with deep learning frameworks (ex. Keras, TensorFlow, PyTorch).
- Experience with JMP and SQL is a plus.
- Expert in data collection and analysis/interpretation, measurement & analysis automation scripting findings, DOE, SPC.
- Effective communication and ability to thrive in a cross-functional development team, excellent problem-solving skills, and the ability to work independently as well as part of a team.

- **[Electric Car Components]**: Diamond-based power electronics for electric vehicles, improving efficiency and reducing size.

## Market Standing
- **Valuation**: Not disclosed (was a unicorn as of Series B). Revenue of $350M (annual) indicates strong growth.
- **Key Metric**: Annual Revenue: $350M (as of most recent data). Total Funding: ~$523M+ across multiple rounds (Series A, B, venture, debt).
- **Notable Investors**: Not explicitly listed in provided data, but funding history includes multiple institutional investors.
- **Growth Signals**: 5 years profitable; >90% global market share for large diamond wafers; headcount up 23.5% YoY (to 259 employees); active job postings up 54.2% YoY; building the largest solar + battery farm in Europe to power its Spain foundry.

## Competitive Advantages
- **Vertically integrated manufacturing**: Designs and builds its own reactor technology and runs all operations in-house, enabling rapid scaling and cost control.
- **First-mover in diamond wafers**: Claims >90% global market share for large single-crystal diamond wafers.
- **Extreme material advantage**: Diamond has 17,200x the semiconductor merit of silicon, offering a massive physics-based moat.
- **Green manufacturing**: Crystallizes greenhouse gas into diamond using zero-emission energy; byproducts are oxygen and water.
- **Profitability**: Rare for a hardware unicorn; has been profitable for 5 years.

## Strategic Focus
- **Near-term (2023+)**: Place a diamond behind every high-power chip, solving the thermal bottleneck for AI, EVs, and 5G/6G.
- **Mid-term (2033+)**: Deliver diamond semiconductors (transistors) that outperform silicon by orders of magnitude.
- **Operational**: Scaling production capacity in the US (Wenatchee, WA) and Spain (Trujillo), including building a massive solar+battery farm.
- **R&D**: Advancing heteroepitaxy and bonding processes in labs in the US and Germany.

## Why Work Here
