The employer's own description
Job Description: About the Team: Our Technology team drives the evolution of our Engineering, Data, Product and User Experience functions. Within this group, the GenAI Experiences team builds generative AI products that define the future of news and business intelligence for millions of users across the Wall Street Journal and Dow Jones brands. Through our Co-Engineering model, we develop production-grade AI capabilities — including summarization, conversational AI, and deep research experiences — in close partnership with Product, Newsrooms, and platform teams. Collaborating across disciplines, we spearhead the development of groundbreaking AI-powered products and technologies. About the Role: Dow Jones is seeking a Senior Software Engineer to join our GenAI Experiences team in Barcelona. In this role, you will take end-to-end technical ownership of complex features and systems, driving delivery with limited supervision and serving as a key technical contributor on the team. You will partner closely with data scientists, ML engineers, product managers, and peer engineering leads to design and ship reliable, scalable AI-powered products. This is an individual contributor role for an engineer who is ready to lead technically on large-scope projects, influence engineering direction, and mentor colleagues — while remaining deeply hands-on in design, implementation, and production operations. You Will: ● Design, build, and own end-to-end delivery of AI-powered features across the GenAI Experiences platform — from backend APIs and data layers to user-facing integrations. ● Partner with product managers, data scientists, and engineering leads to translate business requirements into reliable technical solutions, and surfacing risks and tradeoffs. ● Integrate internal and third-party LLM and AI APIs to extend system functionality and deliver new product capabilities. ● Develop tools and frameworks for prompt management, automated evaluations, and observability. ● Improve team processes — code quality standards, testing practices, observability, and CI/CD pipelines. ● Monitor and improve production AI systems for reliability, performance, and quality — troubleshooting issues across the full stack. ● Integrate third-party AI APIs (internal and external) to extend the functionality of systems. ● Participate in code reviews, apply MLOps best practices, and contribute to team standards for model versioning, experiment tracking, and CI/CD. ● Stay updated on developments in fullstack engineering for GenAI and IR technologies, incorporating best practices and leveraging cloud infrastructure for efficiency. You Have: ● Bachelor's or Master's degree in Computer Science, Engineering, Data Science, or a related STEM field or equivalent work experience. ● 3-5 years of industry software engineering experience building and operating production systems. ● Strong Python skills and experience building scalable backend services and REST or GraphQL APIs. ● Experience with cloud-based infrastructure and services (e.g., AWS and GCP), Docker, and the Git version control system ● Exposure to deploying and monitoring machine learning models or generative AI systems in production environments, including automated evaluation pipelines. ● Familiarity with LangChain, LangGraph, LangSmith, or equivalent agentic/orchestration frameworks. ● Exposure to MLOps tooling — model deployment, monitoring, experiment tracking, evaluation pipelines — is a strong plus. ● SQL proficiency and experience with data pipeline tooling (Airflow or equivalent).
