Original job description

Senior Software Engineer, Full-Stack Applications – Python

Fitch Ratings is seeking a Senior Software Engineer to join our global Ratings Technology team in Toronto. You'll build and maintain mission-critical full-stack applications that power how a world-leading credit ratings agency delivers insights to analysts, executives, and decision-makers who shape global financial markets.

You'll work on Ratings workflow and analytical applications using modern technologies across the full stack - from backend services in Java and Python to frontend applications in React. This role offers the opportunity to work with cutting-edge cloud technologies, contribute to technical solutions, and grow your skills in a collaborative environment.

What We Offer:

• Impactful work – Build applications used by analysts worldwide with direct visibility to your contributions

• Modern technology stack – Work with Java, Python, React, AWS, Kubernetes, and emerging AI technologies

• Continuous learning – Training, certifications, conferences, and clear paths to senior/principal/architect tracks

• Flexible environment – Work from our Manchester office with hybrid flexibility, competitive compensation, comprehensive benefits, and work-life balance

• Innovation culture – Experiment with new technologies, contribute ideas, and help shape technical decisions

We'll Count on You To:

• Develop and maintain full-stack applications – Build robust, scalable applications using Python (FastAPI/Flask), and ReactJS following best practices and design patterns

• Contribute to the development lifecycle – Write clean, maintainable code, implement CI/CD pipelines with GitHub Actions, deploy to Kubernetes, and ensure quality through testing and code reviews

• Work with diverse data technologies – Develop solutions using RDBMS (PostgreSQL, Oracle) and NoSQL (MongoDB) databases, optimize queries, and ensure data integrity

• Collaborate across teams – Partner with product managers, analysts, and other engineers to understand requirements and deliver solutions that meet business needs

• Apply engineering best practices – Follow SOLID principles and design patterns, participate in code reviews, solve technical challenges, and contribute to code quality

• Support and improve systems – Troubleshoot production issues, optimize performance, and help ensure reliability of applications at scale

• Stay current with technology – Learn and experiment with emerging technologies, share knowledge with the team, and contribute to continuous improvement

What You Need to Have:

• Full-Stack Engineering Experience – 7+ years of hands-on experience building enterprise applications and modern web technologies in production environments

• Software Engineering Fundamentals – Strong understanding of OOP concepts, design patterns, SOLID principles, algorithms, data structures, and ability to write clean, maintainable code

• Backend Development – Proficiency in Python (Pandas, FastAPI, Flask) for building enterprise applications, data processing, and API development

• Frontend Development – Experience with ReactJS, Node.js, TypeScript/JavaScript, and modern web development practices

• Database Technologies – Hands-on experience with RDBMS databases (e.g., Oracle, PostgreSQL) and NoSQL databases (e.g., MongoDB)

• DevOps & Cloud – Experience with CI/CD pipelines, GitHub Actions, Kubernetes (K8s), shell scripting (Bash) for automation, and AWS cloud platform

• Effective communication and teamwork – Ability to collaborate with cross-functional teams and communicate technical concepts clearly

What Would Make You Stand Out:

• AI and Machine Learning – Understanding of AI/ML concepts, experience with LLMs, prompt engineering, or integrating AI capabilities into applications

• Data Technologies – Experience with Kafka, PySpark, Parquet and Avro data formats, Apache Airflow for workflow management, or Streamlit for building interactive data applications

• Advanced Data Management – Strong SQL design, query optimization, and database architecture expertise

• Observability – Experience with observability patterns and tools like Datadog, distributed tracing, monitoring, and logging best practices

• DevOps and Infrastructure – Familiarity with ArgoCD for GitOps and Security/Access Management (IAM federation access via Entra ID)

• Financial Services Background – Experience with analytical workflows, financial products, or regulatory processes
