Job description

San Francisco, CA · On-site · Full-time
Compensation: $210,000–$285,000 + 0.25%–0.6% equity

About the Company

A venture-backed AI company automating the document-heavy operational work behind customs brokerage and global trade — using AI agents to read shipment documents, classify goods, and generate compliant customs filings with minimal manual input. The platform cuts customs clearance times to under 5 minutes and has already returned 30,000+ hours to brokerage teams. Past zero-to-one, with strong month-over-month revenue growth and customers processing meaningful operational volume every day.

Industry: AI / logistics / trade compliance

The Role

Own core systems across the full stack — from backend services and data pipelines to the product surfaces operations teams use every day — with full production ownership.

What you’ll be doing

• Build and scale backend services using Python, FastAPI, and TypeScript that power AI agent workflows
• Design and optimize PostgreSQL data models and queries for high-throughput document processing
• Build and manage infrastructure on AWS and orchestrate workflows using Temporal
• Architect and ship React frontend surfaces that give operations teams visibility and control over automated workflows
• Build human-in-the-loop AI interfaces that make AI outputs transparent, explainable, and manageable
• Own AI agent integrations, document ingestion pipelines, and real-time processing systems
• Work directly with founders and customers to ship fast and iterate on what matters

Tech stack: Python, FastAPI, TypeScript, React, PostgreSQL, AWS, Temporal

Requirements

• 5 - 8+ years of professional software engineering experience, with a proven track record in high-growth, fast-paced environments
• Open to 3+ years of experience for candidates with exceptional university pedigree (top 50 school)
• Deep proficiency in TypeScript and React, with the ability to architect complex state management for data-intensive applications.
• Advanced PostgreSQL, schema design, indexing, query optimization
• You are a "builder" who prefers shipping over over-engineering. You write crisp requirements and drive cross-functional delivery with minimal supervision.
• Experience (or a deep interest) in integrating AI APIs and handling complex document extraction workflows.
• You are energized by working shoulder-to-shoulder with founders in our San Francisco office.

Green Flags

• Founding or early-stage engineer on the resume. Has built without scaffolding, before process or teammates existed.
• Production code on both Python/FastAPI and TypeScript/React. Not "familiar with," actually shipped to prod on both sides without handing off either.
• AI API or document extraction in a real product. LLM integrations or OCR that went live; filters out tutorial experience.
• Concept-to-production under startup timelines. Moved fast with minimal direction; look for specifics like "built X in N weeks."
• Held uptime during a scaling event. Didn’t just build green-field, kept something running while it grew fast.
• Enterprise-adjacent exposure (security, compliance, data retention). Signals they’ve thought beyond the happy path.

Red Flags

• Only big tech experience, no startup background
• Needs heavy management or hand-holding. Look for vague ownership language or roles where someone else made the calls.
• Motivated primarily by base over equity and ownership. Signals misalignment with early-stage tradeoffs.
• No experience with data-intensive or real-time systems. Filters out candidates who’ve only worked on simple CRUD apps.
• Internships counted toward years of experience. Years should reflect production ownership, not learning environments.
• Large company only, no startup-speed execution evidence. Big tech tenure without a scrappy chapter is a real risk at this stage.
• No end-to-end production ownership. Has contributed to systems but never owned one fully from build to maintenance.

Why Join

• Real traction past zero-to-one: customs clearance under 5 minutes, 30,000+ hours saved, strong MoM revenue growth
• High-ownership full-stack role with meaningful equity, working shoulder-to-shoulder with founders
• Health insurance fully covered, dental & vision 75% covered, 401k plan
