Senior Backend Engineer

As a Senior Backend Engineer, you'll be at the forefront of building and scaling the infrastructure that powers our product. You'll design and implement robust, high-performance backend systems that handle complex data pipelines, enable seamless AI model deployment, and ensure enterprise-grade security and compliance for our financial services clients. Working closely with machine learning engineers, product teams, and infrastructure specialists, you'll architect scalable solutions that process sensitive financial data with precision and reliability.
This role offers the opportunity to tackle unique technical challenges at the intersection of AI and finance, where your work will directly impact how financial institutions leverage artificial intelligence to transform their operations. You'll drive technical decisions, mentor junior engineers, and help shape the engineering culture as we scale our platform to serve the world's leading financial organizations.
Responsibilities:
Design, develop, and maintain scalable backend services and APIs that power the AI workspace platform.
Build and optimize data pipelines for processing large-scale financial datasets with high accuracy and performance.
Implement robust security measures and ensure compliance with financial industry regulations (SOC 2 GDPR, and FCA requirements).
Collaborate with ML engineers to productionize machine learning models and integrate them into backend systems.
Optimize database schemas and queries for high-throughput, low-latency operations across distributed systems.
Lead technical design reviews and mentor junior and mid-level engineers.
Monitor system performance, troubleshoot production issues, and implement solutions to improve reliability and uptime.
Contribute to engineering best practices, code quality standards, and technical documentation.
Requirements:
7+ years of professional backend engineering experience with a proven track record of building and scaling production systems.
Expert-level proficiency in Python and modern web frameworks, particularly FastAPI (or similar frameworks like Flask or Django).
Deep understanding of relational databases, especially PostgreSQL, including query optimization, indexing strategies, and performance tuning.
Proven experience scaling databases.
Strong knowledge of caching strategies and in-memory data stores, particularly Redis.
Hands-on experience with asynchronous task processing using Celery or equivalent distributed task queues.
Proficiency with message brokers and event-driven architectures (Azure Service Bus, RabbitMQ, Kafka, or similar).
Solid understanding of RESTful API design principles and microservices architecture patterns.
Experience with cloud platforms (Azure preferred; AWS or GCP acceptable) and containerization technologies (Docker, Kubernetes).
Strong knowledge of security best practices, authentication/authorization mechanisms, and data encryption.
Familiarity with CI/CD pipelines, automated testing, and version control systems (Git).
Excellent problem-solving skills with the ability to debug complex distributed systems.
Strong communication skills and experience collaborating with cross-functional teams.
Bachelor's degree in computer science, engineering, or equivalent practical experience.
