## Job description

We are looking for a Manufacturing Software Engineer to develop software tools and dataflows to support operations. Our manufacturing process is highly data driven, and our software tools make that possible by following the material from end to end.  You'll be working with an experienced team of mechanical, electrical, metrology, and manufacturing engineers; both assisting senior engineers and taking responsibility for your own engineering projects. Your goal will be to achieve maximum productivity for our production line through developing performant backend code, clear and intuitive frontend interfaces, and ensuring smooth and secure data flow throughout.

## Responsibilities

- Leading the design, architecture, development, and deployment of new interfaces and logic for handling  material
- Identifying interruptions to data flows and developing solutions to prevent their recurrence
- Collaborating with end users to translate feature requests into actionable software design
- Organizing and maintaining documentation so others are able to understand and use it
- Follow security standards and best practices for data storage, transfer, and change contro

## Requirements

- Bachelor's degree in computer science or a similar engineering discipline
- 3+ years of software engineering in a manufacturing or industrial environment
- Languages & Systems: Python, C#, SQL, JS,  HTTP, Modbus, OPCUA, REST, SCADA, MES, QMS
- Operational knowledge of networking + hybrid cloud designs
- Strong communication and data presentation skills, working directly with internal customers

## About Diamond Foundry

## Company Overview
- **One-liner**: Diamond Foundry creates single-crystal diamond wafers and diamond-based semiconductors to solve the thermal limitations at the core of AI, electric vehicles, and wireless communications.
- **Entity Type**: Private (Series B, multiple debt rounds)
- **Headquarters**: San Francisco, California, USA
- **Founded**: 2013
- **Founders**: Engineers from Stanford, MIT, and Princeton (founded in 2012, incorporated 2013)

## Core Business
- Primary industry: Semiconductor Manufacturing / Advanced Materials
- Target customers: B2B, primarily enterprise partners in AI/cloud compute, electric vehicles, and 5G/6G wireless (chip makers, data center operators, automotive OEMs)
- Mission or purpose: To put diamond behind every chip and eventually deliver diamond semiconductors with 17,200x the semiconductor merit of silicon.

## Products & Services
- **[Diamond Wafer]**: Single-crystal diamond wafers designed to be placed behind high-power chips to solve thermal management. Claims 8x smaller power electronics than Tesla’s.
- **[AI & Cloud Compute]**: Diamond-powered AI datacenter solutions, leveraging diamond’s extreme thermal conductivity to enable faster, denser compute.
- **[Consumer Jewelry (VRAI)]**: Sustainably created diamond jewelry, serving as the company’s consumer-facing brand and proof of its diamond-growing capability.
- **[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
- **Culture**: Described as “focused on creators and creating,” with small teams of hands-on contributors, little hierarchy, and low overhead. High performers can build sizable equity ownership.
- **Work Policy**: Roles are predominantly on-site (Wenatchee, WA; Trujillo, Spain; SF Bay Area, CA; Augsburg, Germany; Dubai, UAE). No fully remote jobs currently posted.
- **Notable Perks**: Work on the “universe’s most extreme material” at the intersection of AI, EVs, and advanced manufacturing. Global opportunities across 9 countries.
- **Engineering Culture**: Deep tech, R&D-heavy environment with a 30-year master plan. Emphasis on innovation and building the future of semiconductors.
- **Diversity**: Global group with operations in the US, Spain, UAE, Germany, Taiwan, and more.
