- Ability to learn new domains quickly, orient oneself in the academic literature, and implement new ideas, creatively borrowing concepts from other modalities and applying them to EEG domain
- Interest in neural data such as EEG, MEG, fMRI as well as building foundation models in a much less explored space
- Proficiency with PyTorch and Python

## QUALIFICATIONS / ADDITIONAL SKILLS:

- Experience with VAEs, GANs, diffusion models, and contrastive learning
- Familiarity with signal processing (especially for EEG) and time-series analysis
- Experience training on large-scale (multi-node) GPU clusters
- Experience contributing to large existing codebases and ramping up quickly
- Previously published machine learning research in well-respected venues

- **Founded**: 2020 (some sources cite 2021)
- **Founders**: Krithik Puthalath (CEO), Beren Millidge (Chief Scientist), Danny Martinelli (Head of Product), Tomás Figliolia (Chief Architect)

## Core Business
- **Primary industry**: Artificial Intelligence / Foundation Models / Cloud AI Infrastructure
- **Target customers**: Developers, enterprises, and "frontier AI hyperscalers" (B2B)
- **Mission or purpose**: "Open Superintelligence" – to enable sovereign, transparent, and customizable AI that runs on any hardware without vendor lock-in.

## Products & Services
- **[Zyphra Research](https://www.zyphra.com/)**: Open-source foundation models trained on heterogeneous compute, focusing on novel architectures for long-term memory, continual learning, and silicon performance. Released as research prototypes.
- **[Zyphra Cloud](https://www.zyphra.com/)**: Full-stack AI platform built on AMD, designed for long-horizon agents. Provides managed infrastructure for deploying, customizing, and running Zyphra's or third-party models with full data sovereignty.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total funding of **$11M** (Series A)
- **Notable Investors/Partners**: AMD, Intel Capital, Future Ventures, Bison Ventures, Transpose Platform, and others
- **Growth Signals**:
  - Headcount grew **151.9% YoY** to 53 employees
  - Operates in 5 countries (US, UK, Canada, India, Saudi Arabia) with offices in San Francisco, Palo Alto, and London
  - Active job postings: 14 (up 16.7% quarterly)
  - LinkedIn followers grew 236.3% year-over-year

## Competitive Advantages
- **Full-stack open-source approach**: Combines novel model architectures (probabilistic computing, heterogeneous compute) with a cloud platform optimized for long-horizon AI agents.
- **Hardware agnosticism**: Promises "run intelligence across any hardware and any provider, without lock-in," with early focus on AMD silicon.
- **Commitment to openness**: Models are transparent, allowing customers to audit reasoning and adapt to specific domains.
- **Sovereignty focus**: Enterprises own their models, data, and deployments – appealing to regulated industries.

## Strategic Focus
- **Priority on architecture innovation** (continual learning, long-term memory, silicon performance) over scaling existing methods.
- **Building a full-stack platform** that tightly couples research breakthroughs with a production-grade cloud service.
- **Scaling the team** aggressively – hiring across research engineering, platform, developer relations, and AI engineering.

## Why Work Here
- **Culture of open research**: Employees contribute to novel model architectures that are publicly released, offering a rare blend of academic freedom and product impact.
- **Heavy engineering focus**: 57% of the team is in technical roles, with a flat structure (62% specialist-level roles).
- **Locations**: San Francisco (HQ) and London, with potential for remote-friendly roles (not explicitly stated).
- **Notable perks**: Not detailed publicly, but typical for a well-funded Series A startup (equity, benefits, etc.).
