Senior Full Stack Engineer - SF

Senior Full Stack Engineer

About the Role

We're hiring a Senior Full Stack Engineer to own critical systems across the entire stack — from backend infrastructure and AI workflows to the frontend applications operations teams rely on every day.

This is a highly technical, high-ownership role where you'll build and scale backend services, architect data models, manage cloud infrastructure, orchestrate distributed workflows, and develop modern frontend experiences that support real-world operational decision-making.

You'll work across Python, TypeScript, React, PostgreSQL, AWS, and Temporal while collaborating directly with founders and customers to rapidly ship impactful product improvements.

This is an ideal opportunity for engineers who thrive in fast-moving startup environments and enjoy owning systems end-to-end in production.

About the Company

The company is building an AI-driven platform transforming operational workflows and document processing at scale.

Backed by leading venture capital firms, the founding team includes experienced leaders from Google, LinkedIn, and Salesforce. The business has already achieved meaningful traction with strong month-over-month revenue growth and customers processing significant operational volume daily.

This is not an early idea-stage company — the platform is already operating in production with real customer impact.

What You'll Do

• Build and scale backend services using Python, FastAPI, and TypeScript
• Design systems powering AI agent workflows and real-time processing pipelines
• Architect and optimize PostgreSQL database models, indexing, and query performance
• Build and manage infrastructure on AWS
• Orchestrate distributed workflows using Temporal
• Develop and ship React frontend applications for operations and workflow management
• Create intuitive human-in-the-loop AI interfaces that improve transparency and operational control
• Build AI integrations, document ingestion systems, and real-time workflow processing
• Work directly with founders and customers to rapidly iterate on high-impact features
• Own systems end-to-end from architecture through production deployment

Required Qualifications

• 5–8+ years of professional software engineering experience
• Experience working in high-growth, fast-paced startup environments
• Deep expertise with TypeScript and React
• Strong frontend architecture and state management experience
• Strong backend engineering experience using Python
• Advanced SQL and PostgreSQL database design experience
• Experience building and operating production systems at scale
• Strong ownership mentality with the ability to work independently
• Comfortable shipping quickly and making pragmatic engineering trade-offs
• Experience collaborating cross-functionally in ambiguous environments
• Based in San Francisco or willing to relocate
• Comfortable working onsite full-time

Visa Support

• H-1B transfers supported
• OPT candidates welcome
• O-1 visa candidates considered
• No new sponsorship available

Preferred Qualifications

• Experience integrating AI APIs and AI-driven workflow systems
• Experience building document extraction or document processing pipelines
• Familiarity with logistics, supply chain, or enterprise workflow platforms
• Background at a high-growth startup or early-stage engineering team
• Interest in high-ownership startup environments with meaningful equity participation

Compensation & Equity

Compensation

• Base Salary: $210,000 – $285,000 USD

Equity

• Equity Range: 0.25% – 0.6%

Benefits & Perks

• Health insurance fully covered
• Dental and vision coverage (75% employer-paid)
• 401(k) plan

Why This Role Stands Out

This is an opportunity to help shape the technical foundation of a rapidly growing AI platform operating at real production scale. You'll work across backend systems, AI infrastructure, distributed workflows, and frontend applications while having direct influence on product direction, architecture, and operational performance.
