- **Compensation:** $115k–$150k

## Job description

- We started by building infrastructure to run CI workloads really fast. Our first product helps companies run GitHub Actions substantially faster and cheaper by owning and operating our own global fleet of bare-metal machines rather than renting generic cloud VMs.
- Today, we orchestrate tens of millions of Firecracker VMs each week, running CI for 7,000+ companies and tens of millions in ARR. We’ve grown 20x in the past 12 months.
- We operate thousands of bare-metal machines across multiple regions, regularly schedule 100k+ vCPUs concurrently, and run a petabyte-scale Ceph cluster that we manage ourselves.
- We’ve raised $58.5M from Seed to Series B, led by Google Ventures (GV) & Peak XV Partners, and we’re intentionally building a small, but exceptional team.
- Blacksmith was founded by a team with deep systems and scaling experience, including building search/ads infrastructure at Faire, and operating large distributed systems at Cockroach Labs. Our GTM is led by Jon Boyer, formerly Head of Sales at Zapier.
- We're now extending the same CI infrastructure into a broader platform: running agent sandboxes at scale and building our own background coding agent on top of it.

As Office Manager, you will own the day to day operations and workplace experience for the Blacksmith San Francisco office. This is a crucial role. We are an in-person team and we want everyone to enjoy the environment they work in. Your role will deliver an experience that means people want to come in, and guests leave feeling impressed.

## What you’ll do

- Own the workplace experience. We want the office to be an enjoyable place to be; the latest technology, high end design touches, fully stocked kitchen, catered lunches. You’ll own this end-to-end.
- Coordinate internal team events, lunches, dinners. And help with coordinating and managing the external customer and network events we’re hosting in the office.
- Employee experience; work anniversaries, birthdays, special events. We want people at Blacksmith to feel recognized and you’ll play a key role in delivering this experience.
- Effectively manage the day to day operations of the office. Vendor management, equipment, supplies, facilities.
- Negotiate and manage vendor contracts.
- Be the first point of contact for all guests.
- Always be looking for ways to improve the office experience.

You’re a good fit if you have

- Experience in delivering exceptional workplace experience in a similar role.
- You understand what makes an in-person office experience enjoyable and can deliver that for the team.
- You enjoy creating experiences - you are excited by the little details, you can anticipate the needs of the team and enjoy delivering an experience that people love.
- You can effectively manage multiple projects simultaneously and have exceptional eye for detail.
- You are comfortable owning logistics and coordinating across the business to deliver initiatives.

## About Blacksmith

## Company Overview
- **One-liner**: Blacksmith is a high-performance CI cloud platform that runs GitHub Actions on purpose-built hardware to accelerate build, test, and deployment workflows.
- **Entity Type**: Private (Startup, backed by Y Combinator and Google Ventures)
- **Headquarters**: San Francisco, CA, USA (with an office in New York City)
- **Founded**: 2024
- **Founders**: Aditya Maru, Aditya "JP" Jayaprakash, and Aayush Shah

## Core Business
- **Primary industry**: Developer Infrastructure / CI/CD (Continuous Integration & Continuous Delivery)
- **Target customers**: B2B, primarily software engineering teams of all sizes (from startups to enterprises) using GitHub Actions
- **Mission or purpose**: To be the compute layer for CI — making developers’ feedback loops as fast as possible by providing a drop-in replacement for GitHub-hosted runners that is faster, more observable, and more cost-efficient.

## Products & Services
- **Blacksmith CI Platform (SaaS)**: A cloud-based service that replaces standard GitHub Actions runners with bare-metal microVMs running on high-performance gaming CPUs. Key features include:
    - **2x faster hardware** (highest single-core performance)
    - **4x faster cache downloads** (co-located caching)
    - **40x faster Docker builds** (NVMe persistence)
    - **Advanced observability** (global log search, inline PR failure comments, job-level insights)
    - **Instant provisioning** and unlimited concurrency
    - Claimed to be 75% more cost-efficient than GitHub runners and a drop-in replacement (one-line YAML change)

## Market Standing
- **Valuation/Market Cap**: Not publicly disclosed
- **Key Metric**: Total Funding (undisclosed amount, but backed by Y Combinator and Google Ventures); also reports **50M+ jobs processed monthly** and **30,000+ happy developers** across **3,000+ organizations**
- **Notable Investors/Partners**: Y Combinator (backed), Google Ventures (backed), and angel investors including Kelsey Hightower (former Distinguished Engineer, Google), Spencer Kimball (CEO, Cockroach Labs), David Cramer (Co-founder, Sentry), Theo Browne (Founder, t3.gg), and Kelvin Beachum (NFL athlete, Arizona Cardinals)
- **Growth Signals**: Launched in 2024, grew to a team of 25, acquired 30,000+ users and 3,000+ customer organizations within the first year, and is actively hiring across engineering, sales, marketing, and operations roles in both San Francisco and New York City.

## Competitive Advantages
- **Purpose-built hardware**: Uses bare-metal gaming CPUs with the highest single-core performance available, specifically optimized for the CI workload, unlike generic cloud VMs from hyperscalers (AWS, GCP, Azure).
- **Co-located caching**: Cache artifacts are stored in the same data center where jobs run, dramatically reducing download times compared to solutions where cache is remote.
- **Cost efficiency**: Claims 75% lower cost than GitHub-hosted runners while providing significantly better performance.
- **Drop-in simplicity**: Integration is a single-line change in the GitHub Actions YAML file, with no credit card required to start.
- **Founding team pedigree**: Founders are University of Waterloo graduates and former engineers at Cockroach Labs and Faire (YC W17), bringing deep infrastructure and scaling expertise.

## Strategic Focus
- **Current priorities**: Scaling the platform to handle increasing job volume, expanding observability features, and building out the go-to-market team (active hiring for Sales, Marketing, and Customer-facing roles).
- **Future direction**: While starting with GitHub Actions, the company plans to expand to other CI platforms such as BuildKite, GitLab, and Jenkins, aiming to become the universal compute layer for CI — going after the $10B CI compute market currently dominated by hyperscalers.

## Why Work Here
- **Culture**: Values-driven environment emphasizing “No passengers,” “Be contrarian,” “Take risks,” “Play hard,” “Show kindness,” and “Stay optimistic.” The team is described as lean (25 people), exceptionally talented, and multidisciplinary.
- **Remote/Hybrid Policy**: Hybrid model with offices in San Francisco and New York City. Roles are listed for specific locations, suggesting in-office presence is expected.
- **Notable Perks**:
    - Competitive salary and equity (with early exercise tax benefits)
    - 5% 401K match (100% on first 3%, 50% on next 2%)
    - Health, dental, and vision insurance
    - Paid family leave
    - Unlimited PTO
    - Birthday off + a Michelin star dinner for you and a +1
    - Team offsites and Michelin star team dinners
    - Choice of mechanical keyboard
    - Lunch on Fridays
- **Engineering Culture**: Small, high-agency team where engineers are expected to own large areas of the product. Strong emphasis on taking risks, moving fast, and building infrastructure from the ground up.
