Office Type: Onsite (5 days/week)
Salary: $180,000 – $230,000 Equity
Company Description
Our client is an early-stage, venture-backed AI startup building conversational agents that can run live product demos and automate sales workflows for B2B companies. Their platform replaces traditional sales motions with real-time, AI-driven interactions that adapt dynamically to user needs.
With strong early traction—including rapid customer growth and increasing demand—the company is scaling quickly from a small founding team. This is a rare opportunity to join at the ground floor, working directly with the founders to define the product, architecture, and engineering culture.
What You Will Do
- Build and ship full-stack features end-to-end, from backend systems to frontend UI
- Design and improve LLM-powered agent systems, including orchestration, evaluation, and self-improvement loops
- Debug real-world production issues using customer conversation logs and system behavior
- Develop generative UI experiences that adapt dynamically based on user interactions
- Build infrastructure for agent performance, versioning, and experimentation
- Work directly with customers to understand product gaps and ship solutions quickly
- Contribute to all areas of the system: backend APIs, frontend interfaces, AI pipelines, and infrastructure
- Operate in a fast-paced environment, shipping daily and iterating rapidly
Ideal Candidate Background
- 0–5 years of software engineering experience (exceptional new grads considered)
- Strong full-stack experience with React (frontend) and Python (backend)
- Experience building and shipping production systems used by real users
- Startup experience or strong interest in early-stage environments
- Strong problem-solving skills and ability to operate in ambiguous environments
- Comfortable working directly with customers and debugging real-world issues
- Based in or willing to relocate to San Francisco (onsite role)
Preferred
- Experience working on AI/LLM-based systems or automation tools
- Background in B2B SaaS, sales tech, or developer tools
- Strong product intuition and ability to make tradeoffs quickly
- Experience building customer-facing features with direct business impact
- Track record of high ownership (e.g., founding engineer, early startup hire, strong internships)
Compensation and Benefits
- Competitive base salary: $180,000 – $230,000
- Meaningful equity as an early founding engineer
- Opportunity to define product, architecture, and engineering culture from day one
- Work directly with founders on high-impact problems
- Fast-paced environment with rapid iteration and learning
- Exposure to cutting-edge AI systems and real-world applications
This role is ideal for engineers who want to operate at the frontier of AI and product development—owning systems end-to-end and building a company from the ground up.
