Role Summary

We are hiring for a Senior Software Engineer - AI Localization & NLP to work on a project focused on intelligent localization systems and AI-powered translation technologies. The selected candidate will build scalable backend solutions, develop and fine-tune transformer-based models, and improve end-to-end localization workflows using modern AI/ML technologies.

Key Responsibilities

• Design and develop AI-powered localization workflows integrating Neural Machine Translation (NMT) and Large Language Models (LLMs).
• Build and improve translation quality estimation systems using COMET, BLEURT, and custom LLM-based evaluators.
• Develop and fine-tune Automated Post-Editing (APE) solutions to improve translation quality, terminology accuracy, and consistency.
• Fine-tune transformer-based models using Hugging Face and domain-specific translation memory and glossary data.
• Build scalable backend services, APIs, and microservices to support automated localization workflows.
• Integrate product systems, Translation Management Systems (TMS), content repositories, and CI/CD pipelines.
• Develop automation frameworks for content extraction, file processing, translation handoff, validation, and linguistic quality assurance.
• Optimize model performance, inference latency, and cloud deployment using AWS services such as SageMaker and Bedrock.
• Build Python pipelines for multilingual data processing, sentence alignment, tokenization, and fuzzy matching.
• Benchmark translation performance using BLEU, chrF++, TER, COMET, and other NLP evaluation metrics.
• Collaborate with localization program teams, product engineering teams, and external suppliers to improve localization processes.
• Contribute to localization engineering standards, shared tools, frameworks, and AI-enabled translation practices.

Must-Have Skills

• 6+ years of software engineering experience, with significant backend or AI/ML experience.
• Strong proficiency in Python.
• Experience working with transformer-based models, including Hugging Face or similar frameworks.
• Hands-on experience training, fine-tuning, and deploying machine learning models.
• Experience with AWS services such as SageMaker and Bedrock.
• Strong experience building APIs, microservices, and system integrations.
• Strong understanding of end-to-end localization workflows, including extraction, translation, review, quality assurance, and release.
• Experience working with Translation Management Systems such as Phrase, Passolo, or similar platforms.
• Experience with SQL/NoSQL databases and cloud-native architectures.

Nice-to-Have Skills

• Experience implementing reference-free Quality Estimation (QE) systems.
• Experience developing Automated Post-Editing (APE) solutions.
• Familiarity with LLM orchestration frameworks such as LangChain.
• Experience integrating localization workflows into CI/CD pipelines.
• Knowledge of automated linguistic quality assurance and validation tools.
• Background in NLP, computational linguistics, or multilingual data engineering.
• Experience optimizing model inference performance and cost efficiency in production environments.
