- **Work type:** hybrid
- **Posted:** 2026-01-19

## Job description

## About the Role

We're looking for a Chief of Staff to serve as a force multiplier for the CEO. This is a part-time contract role (at least 20 hours per week, with flexibility on scheduling) designed for someone who can move fluidly between strategy and execution. This isn't a "shadow the executive" role. You'll own real problems, make real decisions, and have direct impact on how the company scales. The position has a clear path to full-time conversion, with a mutual evaluation at the 3-month mark. The ideal candidate has the horsepower of a top-tier consultant, the scrappiness of an early startup employee, and the judgment to know when to ask questions versus when to just figure it out.

## What You'll Do

- Drive strategic planning: Own the quarterly planning process, track KPIs, and keep the company aligned on what matters.
- Fix what's broken: Identify bottlenecks in how we work, communicate, and ship. Implement solutions without waiting to be told.
- Lead cross-functional projects: Take ownership of high-priority initiatives that don't fit neatly into existing teams, whether that's analyzing a new market, coordinating a product launch, or preparing for a fundraise.
- Maximize the CEO's time: Manage priorities, prepare materials for board meetings and investor conversations, and handle external engagements.
- Support hiring and culture: Help recruit key roles and maintain a strong, unified culture across our SF and Tokyo teams.
- Build the information edge: Conduct research on competitors, market trends, and potential partnerships to inform decisions at the top.

## Requirements

## Experience

- 2+ years in a high-performance environment: top-tier management consulting, investment banking, or Chief of Staff at a high-growth startup.
- Track record of managing complex projects with multiple stakeholders and delivering under pressure.
- Exceptional communication skills. You can take messy information and turn it into a clear, concise narrative.
- Strong analytical and financial modeling skills.
- Native/Bilingual proficiency in English.

Bonus

- Prior experience as a founder or early employee at a venture-backed startup.

Mindset

- Ownership: You treat this like your company. You don't wait for permission to solve problems.
- Adaptability: You're comfortable with ambiguity and can pivot between strategic, financial, and operational challenges without losing momentum.
- Discretion: You'll have access to sensitive information. You operate with integrity and keep confidences.

## About Jinba.io

## Company Overview
- **One-liner**: Jinba provides an enterprise AI workflow builder that lets business teams create and deploy production-ready workflows using natural language, with SOC 2 compliance and on-premise deployment options.
- **Entity Type**: Private (Startup, Y Combinator Winter 2026 batch)
- **Headquarters**: San Francisco, USA (with an office in Tokyo, Japan)
- **Founded**: 2024 (estimated based on YC batch timing)
- **Founders**: Shoya Matsumori (Co-founder and CEO, Ph.D. in machine learning) and Takuya Norisugi (Co-founder and COO, former McKinsey manager)

## Core Business
- **Primary industry**: Enterprise AI Workflow Automation / No-code Development
- **Target customers**: B2B, specifically large enterprises in regulated industries (banking, insurance, financial services) and Fortune Global 500 companies
- **Mission or purpose statement**: Enable enterprises to build AI workflows just by chatting, eliminating the IT backlog and allowing business teams to deploy workflows to production with full compliance controls.

## Products & Services
- **Jinba Flow**: A vibe-coding platform where builders create and deploy workflows using natural language. Workflows can be reviewed and edited visually with flowcharts, integrated with 100+ external services, and published as APIs or batch processes.
- **Jinba App**: The execution environment where users run and interact with deployed workflows. Supports chat-based execution, auto-generated input forms, and MCP (Model Context Protocol) integration for AI agent access.
- **Jinba Toolbox (Beta)**: A centralized tool management and execution platform for AI agents, offering sandbox execution in containers, semver versioning, REST API/SDK/MCP support, and a centralized tool registry.
- **Jinba API**: Enables technical teams to build and deploy custom APIs in minutes without writing code, with 100+ integrations, SSO, RBAC, and audit logs.

## Market Standing
- **Valuation/Market Cap**: Not publicly disclosed
- **Key Metric**: Total Funding — Y Combinator Winter 2026 batch (standard YC deal: ~$125K-$500K); serves 40,000 enterprise users at major financial institutions
- **Notable Investors/Partners**: Y Combinator (Winter 2026 batch); SOC 2 compliant; serves Fortune Global 500 companies in banking, insurance, and other highly regulated industries
- **Growth Signals**: 40,000 enterprise users; YC-backed with active hiring across engineering, sales, and design roles; expanding from San Francisco to Tokyo office; targeting highly regulated industries with compliance-first approach

## Competitive Advantages
- **Natural language workflow creation**: Unlike traditional no-code tools with drag-and-drop interfaces, Jinba lets users describe workflows in plain language, significantly reducing build time (promise of "Prompt to API in 5 minutes")
- **Enterprise-grade security from day one**: SOC 2 compliant with end-to-end encryption, SSO, RBAC, audit logging, on-premise or private cloud hosting, and private model hosting — designed specifically for regulated industries
- **Dual product ecosystem**: Jinba Flow for builders and Jinba App for consumers, with MCP integration allowing AI agents to access workflows
- **Targeting regulated industries**: Built specifically for banks, insurers, and compliance-heavy enterprises that competitors like Zapier, Make, and n8n cannot adequately serve due to security gaps

## Strategic Focus
- **Deep enterprise penetration**: Focused on Fortune Global 500 companies in banking, insurance, and regulated sectors
- **Security and compliance leadership**: Emphasizing on-premise deployment, private model hosting, and SOC 2 compliance as core differentiators
- **AI-native workflow automation**: Positioning as "Lovable meets n8n, but built for the enterprise" — combining vibe-coding with production-ready deployment
- **Global expansion**: Hiring across San Francisco and Tokyo offices, suggesting dual-market strategy (US and Japan)

## Why Work Here
- **YC-backed startup**: Winter 2026 batch with strong founder backgrounds (Ph.D. in ML, McKinsey) and rapid traction (40,000 users)
- **High-impact roles**: Open positions include Founding Engineer, Founding Sales Lead, Chief of Staff, Forward Deployed Engineer, and Founding Design Engineer — offering early-stage ownership and equity
- **Hybrid/remote flexibility**: Roles listed as "On-site" (San Francisco), "Hybrid" (San Francisco and Tokyo), and "Contract Hybrid" — suggesting flexibility depending on role
- **Competitive compensation**: Salary ranges listed for some roles (e.g., $150K-$250K for Founding Engineer roles)
- **Engineering culture**: Emphasis on "making something people want" and "building with AI" — strong technical culture with modern stack
- **Dual-location optionality**: Offices in San Francisco and Tokyo allow for international work opportunities
