Our Translation Management platform enables organizations to automate and streamline every stage of the localization process.\nWe believe innovation happens when talented people collaborate, experiment, and continuously learn. That’s why we foster an inclusive, solution-oriented culture where curiosity, teamwork, and ownership are valued every day. Our mission is to become the leading enterprise Translation Management System - and we’re looking for people who want to help shape the future of global communication technology.\nThe Role\nHybrid Working Requirement: Candidates should be flexible to attend our Marousi, Athens office 3 times per week. Please note that travel or commuting expenses will not be covered for candidates residing outside Attiki or outside a reasonable commuting distance.\nThis is an individual contributor role, and the successful candidate will not have direct people-management responsibilities.\nXTM is looking for an AI Language Scientist to shape how we build and apply artificial intelligence across our translation and localization ecosystem.\nThis is a high-impact role for an AI expert who wants to operate at the intersection of deep technical research, product roadmap, and hands-on engineering. You will be XTM’s core technical authority on AI-helping us identify genuinely useful capabilities, avoid hype, and build high-value, production-ready features for our global enterprise customers.\nPrimary Responsibilities\n1. AI in Language Technology (Core Focus)\nExplore how advances in AI disrupt and enhance traditional translation, terminology, localization, and multilingual content workflows.\nIdentify high-value opportunities where LLMs, RAG, and custom models directly improve automated translation quality, workflow automation, and enterprise localization tools.\nLeverage XTM's existing localization expertise and proprietary data to create unique competitive differentiation.\n2. AI Research & Innovation\nStay at the forefront of AI/ML developments (LLMs, multimodal AI, agentic systems, vector embeddings, fine-tuning).\nDesign and execute prototypes, experiments, and proof-of-concepts to validate new capabilities before handing off to product.\nEstablish rigorous metrics for model evaluation, quality, reliability, accuracy, latency, and cost.\n3. Product & Engineering Collaboration\nWork closely with Product and Engineering teams to turn successful experiments into production-ready capabilities.\nPartner with engineers to move prototypes to scalable implementations and define technical requirements for AI-powered features.\nWrite clean Python code and contribute hands-on technical implementations where appropriate.\n4. AI Strategy & Technical Direction\nPartner with Product, Engineering, and executive leadership to define XTM’s AI vision and technical roadmap.\nConduct build-vs-buy evaluations across models, platforms, frameworks, and AI infrastructure.\nSet internal standards for experimentation, evaluation, responsible AI, and production readiness.\n5. Industry Voice & Community Engagement (Secondary Focus)\nServe as an external voice for XTM by writing occasional research-led articles, presenting at key industry events, or engaging with academic and open-source AI communities. (Note: Primary focus remains internal research and product execution).\nRequirements\nEssential\n5+ years of professional experience in AI, Machine Learning, NLP, Generative AI, or a closely related field.\nDomain Expertise: Proven experience in NLP, translation technology, computational linguistics, or working with large multilingual datasets.\nHands-on LLM Experience: Demonstrated success building with LLMs, modern ML frameworks, transformers, RAG, vector search, and model fine-tuning.\nEngineering Skills: Strong Python skills and the ability to build functional prototypes and write production-grade code alongside engineering teams.\nPragmatic Evaluation: Proven ability to critically evaluate emerging tech against real-world metrics (accuracy, latency, cost) rather than adopting trends.\nCommunication: Exceptional ability to explain complex AI concepts clearly to both technical and non-technical stakeholders.\nHighly Desirable\nAdvanced degree (Master’s or PhD) in Computer Science, AI, NLP, or computational linguistics.\nExperience with agentic AI workflows, tool-using LLMs, and AI observability frameworks.\nPrior experience in enterprise B2B SaaS environments.\nPublished research, patents, or active open-source contributions.\nWhat Success Looks Like (First 12 Months)\nQuarter 1: Established an audit of XTM’s AI capabilities and built a streamlined framework for evaluating emerging models.\nQuarter 2: Delivered initial prototypes that successfully validate new AI-driven language features for the product roadmap.\nQuarter 3: Partnered with engineering to deploy a key AI capability into production.\nQuarter 4: Established XTM’s go-forward AI technical roadmap and served as a recognized internal authority across all product lines.\nBenefits\nWhy You’ll Enjoy Working Here\nAt XTM, we want people to do meaningful work, grow their careers, and have the freedom to innovate.
