About OneInbox

• We're putting voice at the heart of how enterprises actually run.
• We're the production-grade voice AI platform built for Japan and Asia-Pacific.
• We're handling millions of real calls every month — in Japanese, English, Hindi, and Arabic — for banks, real estate firms, and government services.
• Try OneInbox today.

Why we're hiring this role

• We have real production outcomes most AI companies don't — and we're under-telling that story.
• Enterprise procurement in Japan and APAC takes months. Our brand and content need to do work the whole time.
• First marketing hire-level seat with direct line to the founders on positioning and strategy.

What you'll be doing First 30 days

• Audit current site, content, and inbound funnel — what's working, what's not.
• Talk to 5 customers and 3 prospects in active eval to understand how they actually describe us.
• Land on a sharper positioning statement the founders and sales team agree on.

First 60 days

• Ship a refreshed marketing site and 3 customer stories.
• Stand up an editorial calendar covering technical, executive, and operator audiences.
• Run the first paid + organic test cycles and report what actually moved pipeline.

First 90 days

• Build the launch playbook for the next product release.
• Lead OneInbox's presence at the next major industry event in Japan or Singapore.
• Hire (or scope) the first dedicated content or growth marketing role under you.

Who you are

• 3–5 years of B2B marketing — bonus if you've sold or marketed into Japanese enterprise.
• Strong taste for what good looks like — site, content, narrative.
• Bilingual Japanese / English required.
• You can write the first draft yourself — you don't outsource the words.
• Comfortable owning a number that the sales team cares about.

Why OneInbox

• Generational impact: build the voice layer that every APAC enterprise eventually runs on.
• Ownership culture: you'll work close to the founders and ship in days, not quarters.
• Kind, high-bar team: senior operators who've built and led at scaled companies — and are easy to work with.
• Strong backing: institutional investors and committed enterprise customers from day one.

What we offer

• Real ownership: competitive salary and meaningful equity for early team members.
• Health coverage: medical, dental, and vision for you and your dependents.
• Team time: regular in-person off-sites across Tokyo, Singapore, Dubai, and Bengaluru.
• Flexible time off: take what you need, when you need it.
• Learning budget: dedicated annual L&D, plus conference and travel support.
• Daily essentials: catered meals on office days, commuter support, and wellness benefits.
