## Job description

## About Ghost

Ghost is a personal AI hardware company. To realize the full benefit of what models will do for people, we believe an entirely new platform will be built around AI. Some devices will let your AI understand what is happening around you, others will enable you to get things done without navigating apps or menus. As these systems become more capable and more personal, it matters who owns them. We’re building a future where that intelligence belongs to you, with an ecosystem of devices and software that gives you greater control over your time, attention, and the things you want to accomplish.

## What you'll do

- Build and optimize the inference stack that runs personal AI models locally on Core.
- Improve latency, throughput, and memory efficiency across interactive requests and background agent workloads.
- Profile performance across the hardware and software stack, optimizing kernels, memory movement, and runtime execution.
- Build benchmarks that reflect real product workloads, including long contexts, concurrent agents, and sustained operation.
- Work closely with the hardware, post-training, and product teams.

## Who you are

- Experience building or optimizing inference systems for language models.
- Strong systems programming skills in C++ or similar languages, alongside proficiency in Python.
- Familiarity with GPU architecture, memory management, and performance profiling.
- Experience with inference runtimes, quantization, or GPU kernel development using CUDA, Triton, or equivalent tools.
- Strong experimental judgment: you can identify bottlenecks and evaluate tradeoffs between speed, memory, power, and model quality.
- Ability to work on-site in San Francisco.

## About Ghost

## Company Overview
- **One-liner**: Ghost builds personal AI factories—dedicated hardware and software for autonomous AI agents that you own and control.
- **Entity Type**: Private (Seed stage, $10.5M raised)
- **Headquarters**: San Francisco, California, USA
- **Founded**: 2025
- **Founders**: Zain Javaid

## Core Business
- **Primary industry**: Artificial intelligence, consumer hardware, agentic software
- **Target customers**: B2C (individuals who want a personal AI agent) and developers building agent-based systems
- **Mission**: Enable personal intelligence that lives on your own infrastructure, not in the cloud—giving users full ownership and control over their data and AI.

## Products & Services
- **Ghost Personal AI Agent (Software)**: An AI agent that learns from all your emails, files, conversations, and journals; can manage finances, make decisions, run companies, and control smart home devices.
- **Ghost Dedicated Hardware**: Ambient devices (e.g., home assistants, context capture devices) designed for always-on, autonomous AI operation—unlike phones or laptops that are human-driven.
- **Ghost Ecosystem**: A new computing paradigm where agents work 24/7 without waiting for app launches, handling tasks proactively.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total funding $10.5M (Seed round)
- **Notable Investors/Partners**: a16z, Abstract, Audacious, SV Angel, Nova, Cory Levy, Max Mullen
- **Growth Signals**: Extremely small team (~5 employees) with high talent density; hiring founding engineer; ambitious vision for a new computing primitive; founders and team come from top quant shops and universities.

## Competitive Advantages
- **Ownership & Privacy**: Unlike cloud-based AI, Ghost’s agents run on hardware you own, ensuring data never leaves your control.
- **Purpose-built Hardware**: Designing devices specifically for autonomous, ambient AI operation rather than repurposing smartphones or laptops.
- **Small, Intense Team**: Highly selective, talent-dense team working on the hardest unsolved problems in agentic systems.

## Strategic Focus
- Build the next generation of consumer AI hardware and operating system for personal intelligence.
- Develop context capture devices (transcription, video, etc.) and fully local home assistants.
- Create an ecosystem where agents are always accessible and can act autonomously over days and weeks.

## Why Work Here
- **Culture**: “Aggressively young, talented team” that values endurance and deep technical work. Team members have turned down millions in cash/equity from top firms to build real products.
- **Work Environment**: San Francisco-based; likely in-office given the hardware focus. Job posting for founding engineer is in SF.
- **Perks & Engineering**: Well-funded seed stage with competitive salary ($130k–$220k for founding engineer). Engineers are expected to use AI agents to write >90% of their code. Opportunity to define a new computing primitive from the ground up.
