Senior Software Engineer

Job Description

### **KEY FACTS**

* Base salary: $290,000--$310,000

* Location: San Francisco or PA • 5 days in-office
* Experience: 6+ years, 2+ at senior level with consumer-scale product ownership

### **Why This Role Is Unique**

As a Senior Software Engineer, you sit at a rare intersection: working directly with OpenAI's research team on frontier model capabilities while shipping those breakthroughs into a consumer product that touches millions of people's financial lives. Most engineers get one or the other. Here you get both.

### **What You'll Do**

* Own a core system end-to-end: multi-model AI orchestration, financial data aggregation, Computer Use engine, agent platform runtime, or consumer app architecture.
* Set technical direction. Make decisions that shape how the product scales to millions of users.
* Mentor and unblock mid-level engineers. Raise the team's bar by example.
* Work directly with Bruce (CTO) on architecture. Ship production code daily.

### **What We're Looking For**

* 6+ years production engineering, 2+ years senior-level ownership at a consumer-scale product.
* Deep chops in one or more: distributed systems, AI/LLM at scale, mobile app architecture, real-time data systems, browser automation / agent runtimes.
* Shipped a product that 1M+ people use.
* Extreme AI fluency. Rebuilt their engineering workflow around AI to move 3x faster.
* Hunger over credentials. Fast-shipping startup generalist over brand-name coaster.
* Preferred: Top 20 CS degree + 2+ startups. Exception: exceptional startup shipping record with deep system ownership.
