Company is built as a native "vibe coding" platform; the role sits at a vibe-coding startup—not a coding role but embedded in that product context.

About the Role

Part-time Chief of Staff supporting the CEO at Jinba, responsible for driving strategic planning, leading cross-functional initiatives, and improving operational processes. The role is hybrid in San Francisco, requires at least 20 hours/week, and has a path to full-time conversion after a 3-month evaluation.

Job Description

Role

Chief of Staff to the CEO at a venture-backed startup.

Key Responsibilities

  • Fix operational bottlenecks: identify and implement solutions to improve how the company works, communicates, and ships.
  • Lead cross-functional projects: manage high-priority initiatives that span multiple teams (market analysis, product launches, fundraise prep, etc.).
  • Maximize the CEO’s time: manage priorities, prepare board and investor materials, and coordinate external engagements.
  • Support hiring and culture: help recruit key roles and maintain a unified culture across San Francisco and Tokyo teams.
  • Build the information edge: research competitors, market trends, and partnership opportunities to inform leadership decisions.

Requirements

  • 2+ years in a high-performance environment such as top-tier management consulting, investment banking, or a Chief of Staff role at a high-growth startup.
  • Proven track record managing complex projects with multiple stakeholders and delivering under pressure.
  • Exceptional communication skills with the ability to synthesize messy information into clear narratives.
  • Strong analytical and financial modeling skills.
  • Native or bilingual proficiency in English.

Bonus Qualifications

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

Mindset & Traits

  • Ownership: treats problems as if it were your company and proactively solves them.

  • Discretion: able to handle sensitive information with integrity and maintain confidentiality.

Logistics

  • Employment type: Part-time (Contract), hybrid in San Francisco.
