Fitch Group is currently seeking a Senior Software Engineer – Python based out of our Toronto office. How You'll Make an Impact:

• Design, develop, and maintain robust Python-based backend services and APIs using FastAPI/ asyncIO, and architect scalable data pipelines for ingestion, transformation, and delivery of large datasets
• Build and manage streaming and event-driven architectures using Apache Kafka, RabbitMQ, and AWS SQS, and deploy cloud infrastructure on AWS (Lambda, EC2, ECS, S3, RDS, DynamoDB)
• Design and optimize both relational and non-relational databases, and integrate AI/ML models and services, including LLMs and cloud AI APIs
• Develop and maintain CI/CD pipelines, champion containerization with Docker and Kubernetes/ECS, and enforce version control best practices using GitHub
• Establish and enforce coding standards, design patterns, and governance frameworks, including architecture decision records, API standards, and security best practices, promoting TDD and clean architecture principles
• Lead Proof of Concept (POC) initiatives to evaluate new technologies and present trade-off analyses and recommendations to stakeholders
• Take full end-to-end ownership of critical applications, managing incidents, escalations, documentation, performance monitoring, and technical debt
• Mentor and coach junior and mid-level engineers through code reviews, knowledge-sharing sessions, and tech talks, while contributing to technical roadmaps and platform strategy
• Demonstrate strong soft skills including clear communication, collaboration, accountability, adaptability, and a continuous learning mindset

You May be a Good Fit if:

• 7+ years of professional software engineering experience with Python as the primary language
• Strong experience with AWS services (e.g., Lambda, S3, ECS/EKS, SQS, RDS, DynamoDB, IAM)
• Hands-on experience building and maintaining CI/CD pipelines (GitHub Actions, CodePipeline, Jenkins, or equivalent)

• Practical experience with message brokers and streaming platforms (Apache Kafka, RabbitMQ, AWS SQS/SNS)
• Experience building RESTful/GraphQL APIs with FastAPI (or equivalent frameworks such as Flask/Django REST/asyncIO)
• Experience designing and building data pipelines (batch and/or real-time)
• AI fluency – familiarity with integrating AI/ML services, LLM APIs (e.g., OpenAI, AWS Bedrock), or building AI-powered features
• Demonstrated experience owning and delivering end-to-end applications in a production environment
• Proven track record of mentoring engineers and contributing to team growth
• Experience leading or contributing to POC initiatives and translating outcomes into actionable decisions
• Strong understanding of software governance, coding standards, and engineering best practices

What Would Make You Stand Out:

• Familiarity with Apache Spark or other distributed processing frameworks
• Knowledge of MLOps practices and model deployment
• Experience working in Agile/Scrum environments
