Meet the team behind this journey

Our linguists are language and industry experts whose work shapes the products millions of Deep L users rely on to communicate.

As a Japanese linguist, you’ll work at the intersection of Research and Product—shaping how our technology understands and produces language, one nuanced decision at a time.

You’ll test features before they launch, dig into ambiguous or complex language data, and turn linguistic complexity and industry know-how into insights that stakeholders across the company can act on.

Alongside a global team of language specialists, you’ll help define what "good" translation means for Japanese, guide our freelance linguist network, and use AI to work smarter and faster.

It’s a role built for someone who’s as comfortable explaining a subtle grammatical point to a non-linguist as they are debating error patterns in machine output with a researcher.

• Your Responsibilities
• Serve as a linguistic consultant for your language across the company, interacting with a wide range of stakeholders from Research to Product to Sales and beyond and helping to develop products and features that redefine work in the language industry
• Test and evaluate Deep L’s products and their features both before and after launch
• Assess the linguistic quality of data generated by both humans and machines
• Design tests and examples to help Deep L identify the right freelancers for linguistic projects
• Evaluate work done by freelance linguists and provide them with actionable feedback based on project needs and expectations
• Work with ambiguous and/or highly complex language data in your language plus at least one foreign language
• Investigate and evaluate language complaints submitted by users and offer your linguistic analysis
• Partner with stakeholders on experiment and evaluation design, bringing linguistic and user‑expectation reasoning to help inform what to test, what to validate, and how to measure it
• Experiment with AI to accelerate individual and team processes
• Explain linguistic phenomena to a wide range of target audiences, from those with little to no linguistic expertise to fellow linguists
• Qualities we look for
• Deep familiarity with the cultural and professional context where the language is natively spoken, typically gained through education or substantial working experience in Japan, ideally native‑level speaker of Japanese
• English fluency (C1+)
• Bachelor’s degree in linguistics, translation, foreign languages, language teaching, or a related field
• At least 2 years of experience working in translation, localization, linguistics, education, or a related field
• Demonstrated ability to break down complex linguistic matters in a way that anyone can understand, including non‑speakers of that language
• Deep knowledge of and familiarity with reputable linguistic resources for Japanese
• Expert understanding of research best practices
• Experience working with machine translation and identifying error patterns common to machine output
• Exceptional communication skills, both written and spoken
• Experience with AI prompting or a basic understanding of LLMs, NLP, AI or experience in AI-led workflows
• Comfortable working in a dynamic environment and adapting to new circumstances
• The ability to work both independently and as part of a team
