## Job description

## About Us

[Vast.ai](https://vast.ai)’s cloud powers AI projects and businesses all over the world. We are democratizing and decentralizing AI computing—reshaping our future for the benefit of humanity. We are a growing and highly motivated team dedicated to an ambitious technical plan. Our structure is flat, our ambitions are out‑sized, and leadership is earned by shipping excellence. We seek engineers with strong intrinsic drive, a true passion for advancing the state of the art, and a mix of architecture, coding, and communication skills. LOCATION: On-site at our office in San Francisco or Westwood, Los Angeles.

## About the Role

As a Senior Infrastructure Engineer, you will help design and scale the core systems that power Vast.ai’s global GPU marketplace. You’ll work closely with our founders and core engineering team to extend the underlying compute infrastructure — from GPU provisioning and scheduling to billing, orchestration, and marketplace dynamics. We’re looking for someone who has previously built large-scale infrastructure platforms — systems with similarities to Vast.ai, or distributed compute orchestration frameworks. Full-time · On-site at either our SF or LA offices Tech Stack Python, C++, PostgreSQL, Linux, Docker, KVM, Redis, Terraform, AWS, REST/gRPC APIs Ideal Experience

- Distributed Systems: Experience building high-throughput backend systems or compute clouds
- Compute Orchestration: Familiarity with Docker, or custom scheduling frameworks
- GPU Infrastructure: Understanding of GPU provisioning, driver management, and workload scheduling
- Billing & Metering: Implemented or integrated usage-based billing and account credit systems
- Marketplace Dynamics: Knowledge of dynamic pricing, spot instances, or supply-demand balancing mechanisms
- Security & Multi-Tenancy: Experience designing secure, multi-tenant systems in cloud environments
- Programming: Strong programming skills in Python and C++; ability to write performant, maintainable, well-architected code
- Database Expertise: Comfortable designing schemas and queries for large-scale data systems (PostgreSQL preferred)

Bonus points for:

- Experience with GPU security, virtualization, or zero-trust compute isolation
- Prior startup experience or end-to-end product ownership

## Key Responsibilities

- Improve the backend systems that power Vast.ai’s compute marketplace
- Integrate GPU provider onboarding, usage tracking, billing, and orchestration APIs
- Develop scalable infrastructure for workload scheduling and resource management
- Optimize pricing and marketplace logic for efficiency and transparency
- Benchmark, profile, and harden systems for performance, reliability, and fault tolerance
- Collaborate with product and infrastructure teams to shape the future of decentralized compute

Interview Process (≈ 1 week) After submitting your application, our technical team reviews your credentials. If selected, you’ll proceed through the following stages:

- 15 min – Initial screening with member of your future team (virtual)
- 40 min – Systems and architectures (virtual)
- 1 hour – LLM-assisted coding assessment (virtual)
- 2 hours – Meet and greet with coding assessment (on-site)

## Benefits

- Comprehensive health, dental, vision, and life insurance
- 401(k) with company match
- Meaningful early-stage equity
- Onsite meals, snacks, and close collaboration with founders/tech leaders
- Ambitious, fast-paced startup culture where initiative is rewarded

## About Vast.ai

## Company Overview
- **One-liner**: Vast.ai operates a decentralized GPU marketplace that enables developers and AI agents to provision and manage compute power across a global network of hardware, offering a cost-effective alternative to hyperscaler clouds.
- **Entity Type**: Private (raised $30M in funding)
- **Headquarters**: Los Angeles, CA (1100 Glendon Ave, STE 1840) and San Francisco, CA (100 1st Street, STE 2250)
- **Founded**: 2016 (incorporated June 28, 2016)
- **Founders**: Jake Cannell (CEO) and Christian Horne

## Core Business
- **Primary industry**: Cloud infrastructure / GPU compute / AI infrastructure
- **Target customers**: AI researchers, ML engineers, AI agent developers, enterprises needing GPU compute for training and inference
- **Mission**: "To organize, optimize, and orient the world's computation."
- **Vision**: "To make life substrate-independent through Vast Artificial Intelligence."

## Products & Services
- **GPU Cloud**: On-demand instances across 20,000+ GPUs in 40+ data centers. Deploy via CLI, SDK, Python API. Per-second billing. Real-time pricing set by supply and demand. [vast.ai](https://vast.ai/)
- **Serverless Inference**: Deploy models as endpoints with automatic GPU optimization, auto-scaling to zero, pay-per-compute-time. [vast.ai](https://vast.ai/)
- **GPU Clusters**: Dedicated multi-node clusters with InfiniBand networking for large-scale training. [vast.ai](https://vast.ai/)
- **API & SDK**: REST API, Python SDK, CLI for programmatic compute provisioning. Agent-native interface for autonomous compute procurement. [vast.ai](https://vast.ai/)

## Market Standing
- **Valuation**: Not publicly available
- **Key Metric**: Total funding $30M (as of 2026, per jobsbyculture.com) [jobsbyculture.com](https://jobsbyculture.com/blog/working-at-vast-2026)
- **Notable Investors/Partners**: Not disclosed in available sources
- **Growth Signals**:
  - 310% year-over-year growth (2024–2025)
  - 20,000+ GPUs, 350+ hosts, 700K+ transactions/month
  - SOC 2 Type I certification achieved in 2024
  - Enterprise and Secure Cloud offerings launched; customers include professional data center partners
  - Headcount grew from fully distributed team to 40+ employees across two offices (LA & SF) [vast.ai/about](https://vast.ai/about)
  - Conflicting reports: jobsbyculture.com cites ~30 employees, while vast.ai/about states "40+ employees"

## Competitive Advantages
- **Decentralized marketplace model**: Taps into underutilized GPU hardware (gaming rigs, mining farms, research labs, small data centers) to offer compute at 3–5x cheaper than AWS, no contracts required.
- **Agent-ready infrastructure**: The same API used by developers is designed for AI agents to autonomously procure and optimize compute – a moat for the upcoming agentic economy.
- **Real-time, transparent pricing**: Prices set by supply and demand, programmatically queryable via API. No hidden costs or enterprise sales friction.
- **Heterogeneous hardware support**: 68+ GPU types across 40+ data centers, enabling users to compare and switch between hardware types easily.
- **SOC 2 certified**: Security and compliance for enterprise workloads.

## Strategic Focus
- **Agentic compute**: Building an "infrastructure layer where AI agents design, procure, and optimize their own compute" [vast.ai](https://vast.ai/)
- **Enterprise expansion**: Growing Secure Cloud (certified data centers) and dedicated cluster products for professional customers.
- **Scaling the network**: Increasing GPU count, host partnerships, and geographic diversity while maintaining real-time pricing and low latency.
- **Open infrastructure**: Keeping compute distributed and independent, countering hyperscaler concentration.

## Why Work Here
- **Culture**: "High level of rigor, precision, and professionalism" – employees are stakeholders who own the impact of their work. Fast-paced startup environment where initiative is rewarded. [vast.ai/about](https://vast.ai/about)
