Core Responsibilities

Primary Functions

Translate a wide range of source materials from Japanese to English and English to Japanese, including marketing copy, websites, product UI strings, help center articles, user guides, legal contracts, medical/pharmaceutical documents, and technical manuals while ensuring accuracy, consistency, and cultural relevance.
Localize web and mobile app content by adapting tone, idioms, date/number formats, and user interface text to meet the expectations of Japanese-speaking audiences and maintain UX consistency across platforms.
Perform transcreation of creative and marketing assets (advertising, social media posts, campaigns, taglines) to preserve persuasive intent, brand voice, and campaign KPIs while complying with local regulations and cultural norms.
Proofread and edit translations produced by in-house or freelance linguists to ensure grammatical accuracy, style conformity, correct register, and adherence to brand and client style guides.
Conduct linguistic quality assurance (LQA) and pre-release checks, including string-length verification, placeholder handling, non-translatable element checks, and testing in context to prevent truncation or UI overflow.
Post-edit machine translation output (PEMT) to achieve publishable quality using established guidelines, correcting mistranslations, hallucinations, register shifts, and terminology inconsistencies.
Build, maintain, and update translation memories (TMs), glossaries, and style guides; enforce consistent use of approved terminology and support centralized terminology management workflows.
Use industry CAT tools and localization platforms (e.g., SDL Trados, memoQ, Memsource/Now Smartling, Wordfast, Across) to manage translation projects, leverage TMs, and improve turnaround while tagging segments and managing metadata correctly.
Prepare bilingual deliverables, markups, and translation packages for engineering and QA teams; export/import resource files (CSV, .resx, .po, .xliff) and validate encoding and character set integrity (UTF-8, Shift_JIS).
Collaborate cross-functionally with product managers, developers, designers, QA, legal, marketing, and customer support to clarify requirements, resolve ambiguous source text, and prioritize localization tasks.
Create SEO-optimized translated content by conducting Japanese keyword research, incorporating localized keywords naturally, and advising content teams on localized metadata, titles, and descriptions to increase organic visibility.
Manage subtitles and captions for video content: translate dialogue, localize on-screen text, create time-sync scripts, perform subtitle editing for readability, and ensure compliance with broadcast or platform guidelines.
Localize voice-over and narration scripts; liaise with voice talent and audio teams to confirm pronunciation, tone, and direction; provide phonetic transcriptions and pronunciation notes when required.
Review, qualify, and manage freelance translators and interpreting vendors; negotiate rates, provide project briefs, and perform onboarding and periodic quality audits to maintain vendor pools.
Provide cultural consulting and sensitivity reads for campaigns, product features, and legal/public-facing communications to mitigate cultural risk and ensure brand-safe localization.
Estimate translation project scope, timeframes, and cost using metrics such as word counts, complexity, TM leverage, and required linguistic QA; provide clear delivery timelines and escalation paths.
Implement and follow security and confidentiality protocols when handling sensitive client or regulatory documents, including NDAs and data protection best practices.
Participate in Agile localization processes: attend sprint planning, daily standups, and retrospectives to align translations with development cycles and releases.
Troubleshoot localization issues such as broken strings, concatenation errors, placeholder mismatches, context-less segments, and character encoding problems by liaising directly with engineering and QA teams.
Conduct linguistic validation and usability testing with native users where required (medical, clinical, or regulated content) to confirm comprehension and cultural appropriateness.
Train and mentor junior translators and linguists on best practices for CAT tools, terminology management, quality assurance checklists, and client-specific style requirements.
Maintain up-to-date knowledge of industry trends such as neural machine translation (NMT), localization automation, and accessibility (WCAG) considerations to continuously improve workflow efficiency and output quality.
Produce clear post-project reports summarizing TM gains, quality metrics, recurring issues, and improvement actions for stakeholders and localization managers.
Manage multiple simultaneous translation projects, prioritize tasks effectively, and ensure on-time delivery under tight deadlines while maintaining high linguistic quality.
Support multilingual content launches by coordinating linguistic readiness checks, packaging localized assets, and validating final builds in staging environments prior to release.

Secondary Functions

Assist in building and refining centralized glossaries, shared style guides, and onboarding documentation for cross-functional teams and external vendors.
Support ad-hoc localization or linguistic research requests such as competitor language analysis, regional copy testing, and tone-of-voice calibration.
Help develop internal training materials on localization best practices, CAT tool tips, and quality assurance processes.
Participate in product and marketing brainstorming sessions to provide early-stage linguistic and cultural input that drives global product-market fit.
Contribute to continuous improvement initiatives for localization workflows, including automation, TMS integrations, and quality tracking dashboards.
Provide ad-hoc interpretation support (consecutive or liaison) for client calls, user interviews, or stakeholder meetings when needed.
Assist in periodic audits for compliance with regulatory requirements and language accuracy for markets requiring certified translations.
