Job description

About Fractional AI
How do you turn a decades-old dataset into an industry-leading medical coding agent? Teach an AI receptionist to book appointments in Spanish? Automatically generate working data connectors from API docs? Build agents that write, test, and deploy their own software packages?
Fractional AI is focused on putting frontier AI to work. We're a group of veteran Silicon Valley builders who care deeply about getting complex AI systems built right, with strong conviction about what makes them succeed.
We're backed by Anthropic, Blackstone, Hellman & Friedman, Goldman Sachs, General Atlantic, Leonard Green & Partners, Apollo Global Management, GIC, and Sequoia Capital.
We're headquartered in SF with offices in NYC, Raleigh-Durham, and Dubai.
The Role
This role is designed for strong software engineers who want to ship AI products end-to-end across a range of domains, with meaningful ownership from day one.
You'll work on a small, high-caliber team (2-5 engineers and a PM) building AI products for our clients, from requirements gathering and prototyping through system design, development, testing, and deployment. You'll own features end-to-end, and develop domain expertise across a range of AI use cases.
You'll spend most of your time in code, with meaningful client exposure - frequently interacting with the client's team to make sure what we're building meets their needs.
Most engineers take a decade to see this range of hard problems across this many domains. Here, you'll do it in your first year. To make this possible, we are religious about being the best company in the world to learn Applied AI engineering practices.
What You Bring
  • Experience consistently shipping high visibility or high impact software, with deep care for the craft. We strongly prefer candidates with 4+ years of experience, although we understand it's only one proxy for impact. Exceptional signals elsewhere (AI evangelism, OSS contributions, founder experience) can substitute.
  • Specific interest in applying software engineering fundamentals to AI systems. You care about balancing frontier model capabilities with good system design.
  • Comfort talking with senior technical stakeholders. You navigate conversations skillfully, and care about people using what you build.
  • High ownership mindset. You jump in without instruction, embrace a "no job too big, no job too small" mindset, and want to shape strategy and culture.
  • Low ego, high integrity. You help others and ask for help. You hold a high bar for honesty-with yourself and your team.
Our Engineering Philosophy
We're opinionated about what works in production, and we write about it - from why most eval setups fail by collapsing everything into a single score, to why defaulting to chat interfaces limits AI's impact.
We have a distinct approach to building AI systems: applying standard software engineering discipline to the non-deterministic world of frontier AI. We design systems around testable hypotheses, curate durable data sets, and ensure what we ship keeps working long after we've handed it over.
After shipping 30+ AI products, we have strong opinions on what makes AI products succeed and how to get them into production. We think you'll find it refreshing if you've seen how most companies approach AI.
How Fractional Is Different
A typical engineer here ships two to three products per year and learns from dozens more. You have outsized autonomy on each product - but you won't have a year to polish a single system. The upside is constant time on the frontier of models and tooling, and a muscle for AI product development that's hard to build anywhere else.
Most engineers look back at this as the biggest growth period of their career. But it's possible you won't like it - we recommend using the interview process to hear what our engineers think.
Our Values
  • Overdeliver: We are writing the playbook on how to create enterprise value with LLMs, and building our reputation as the world's best applied AI team.
  • Overuse AI: We go out of our way to experiment with the latest tools and share what we learn with our teammates - building a culture at the frontier.
  • Over "engineer" the culture: For every big decision, we ask "would this make Fractional a better or worse place for our team?"
Location
San Francisco, CA
Work Arrangement: 4 days in-person, Fridays remote
Benefits
  • Competitive Compensation Package: Attractive salary aligned with your experience and skills.
  • 401k with Matching: Invest in your future with our company-matched retirement plan.
  • Unlimited PTO: Take the time you need to relax and rejuvenate.
  • Exceptional Medical, Dental, and Vision Coverage: Comprehensive health benefits to keep you and your family healthy.
  • Health FSA: Manage out-of-pocket health expenses effectively.
  • Commuter Benefits: Make your travel to work easier and more affordable.
  • Life Insurance: Providing peace of mind for you and your loved ones.
  • Team Events and Activities: Regular events to build camaraderie and a strong team spirit.
