Job Title: Senior AI/ML Software Engineer – Localization

Job Location: Hybrid – Vancouver, BC, Canada

Job Type: T4 Contract

Experience: 6+ Years

Rate: CAD 70 - 75 per hour

Role Summary: NearSource is seeking a Senior AI/ML Software Engineer - Localization to architect and scale intelligent localization systems using advanced AI, Natural Language Processing (NLP), and machine translation technologies.

The role will focus on developing production-ready AI-powered localization pipelines, fine-tuning transformer-based models, and delivering scalable backend solutions that enhance translation quality, automation, and enterprise localization workflows.

Key Responsibilities

AI-Powered Localization Architecture

• Architect advanced localization workflows integrating Neural Machine Translation (NMT) and Large Language Models (LLMs) for translation refinement.
• Design and implement reference-free Quality Estimation (QE) systems using COMET, BLEURT, or custom LLM-based evaluators.
• Develop and fine-tune Automated Post-Editing (APE) solutions to improve translation fluency, terminology accuracy, and stylistic consistency.
• Fine-tune transformer-based models using Hugging Face and domain-specific translation memory and glossary data.
  
  
  

Backend Engineering and System Integration

• Architect and develop scalable backend services, APIs, and microservices supporting automated localization workflows.
• Design integrations across product systems, Translation Management Systems (TMS), content repositories, and CI/CD pipelines.
• Develop automation frameworks for content extraction, file processing, translation handoffs, validation, and linguistic quality assurance.
• Optimize model inference, performance, and cloud deployment using AWS services, including SageMaker and Bedrock.
  
  
  

Data Engineering and NLP

• Develop Python-based pipelines for multilingual data curation, sentence alignment, tokenization, and fuzzy matching.
• Benchmark translation performance using BLEU, chrF++, TER, COMET, and other NLP evaluation metrics.
• Drive workflow optimization through intelligent automation, data processing enhancements, and scalable system architecture.
  
  
  

Technical Leadership

• Establish technical standards for localization engineering and AI-driven translation quality.
• Partner with Localization Program Management and product engineering teams to align technical execution with localization strategy.
• Provide technical guidance on localization tooling, automation frameworks, and AI-enabled localization practices.
• Contribute to the evolution of shared localization platforms, engineering tools, and technical standards.
  
  
  

Must-Have Skills

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

Nice-to-Have Skills

• Experience implementing reference-free Quality Estimation (QE) or 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.
  
  
  

Interview Process

The selection process is expected to include 2-3 interview rounds:

• Round 1: 30-minute Hiring Manager discussion.
• Round 2: Technical interview focusing on AI knowledge, system design, and coding.
• Additional Round (if required): Behavioural or technical assessment based on the candidate's profile and interview feedback.
