Description

Founding Engineer

Location: San Francisco

Department: Engineering

Location Type: HYBRID

Employment Type: FULL_TIME

With the advent of reasoning models, intelligence has become a commodity. Judgment has not. 

A $400B industry built on selling intelligence-for-hire -  management consulting (think Mckinsey, BCG, Bain) - is on the brink of massive disruption. We’re reimagining how intelligent, outcome-oriented business decisions get made when AI systems can reason at scale but human judgment still sets the direction.

We’re building the Claude Code for consultants — an AI-native operating system for business decisions. Our agents synthesize fragmented systems and workflows, turning messy data into crisp, actionable insight in seconds. 

We’ve raised a $10M seed from Tier 1 VCs.

Why Join Us


Own the architecture and direction of the product 
  • Work directly with experienced founders (ex-Google, ex-PE&consulting)
  • Tackle complex, high-impact problems that transform how millions work 
  • Move fast with a small team that values clarity, craftsmanship, and curiosity
  • Shape the company’s DNA — engineering culture, technical stack, and what “good” means


What You’ll Do

  • Design and build our core intelligence engine end-to-end: data ingestion, model orchestration, feedback loops, API layers, UI integration
  • Own the architecture across stack boundaries (Python / Go / TS) to support scalable, evolvable systems
  • Partner with founders on roadmap, trade-offs, and technical vision
  • Define what great engineering looks like in an AI-first organization


You Might Be a Great Fit If


Mindset & Style:

  • Generalist who thrives in ambiguity and doesn’t wait for perfect specs
  • Think like an owner: big picture, not just your part. Obsessed with outcomes
  • Build iteratively: ship quickly, measure, improve, repeat
  • You care about velocity, craftsmanship, and simplicity
Experience & Skills: 
  • Shipped meaningful products end-to-end (bonus: startup or small-team experience)
  • Strong foundations in distributed systems, data, or AI/ML
  • Fluency in modern stacks: TypeScript, Python, Go, Postgres, React.  But we care more about how you think than what you know.
  • You know how to balance “just enough abstraction” vs overengineering
  • Willing to work 3 days a week out of our San Francisco office

Who you will work with: 


Our founders bring deep technology experience (Google-scale systems serving hundreds of millions of users) and domain expertise in high-stakes business decisions from top consulting and private equity firms.


Why this matters


85% of the global economy runs on enterprises. The biggest frontier in enterprise AI is not just better models - it’s judgment at scale. You’ll build the infrastructure, pipelines, and reasoning layer that let large organizations turn messy data into crisp, decisive outcomes.
You won’t just write code; you’ll invent the scaffolding of a new AI operating system for decisions.
