The full description lives on the employer’s site. Open the listing.

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.

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)

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.

[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.

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.

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.

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.
