You’ll design and implement scalable, fault-tolerant, and reusable architectures that enable rapid feature development and seamless integration across our platform. This role is crucial in bridging the gap between our legacy mixed-technology environment and a future-ready, unified architecture. The Senior Software Architect will be a visionary, spearheading efforts in re-architecting the application stack with a focus on microservices, promoting reusability, and ensuring scalability across our diverse business units.

Key Responsibilities

• Design and implement robust, scalable software architectures that promote code and data reuse across applications and business units


• Lead the transition from monolithic applications to a microservices-based architecture, ensuring loose coupling and high cohesion


• Develop and maintain a comprehensive API strategy, including RESTful and GraphQL APIs


• Design and implement caching strategies (e.g. Redis) to optimize performance


• Architect solutions for data consistency and integrity in distributed systems, implementing patterns such as CORS and Event Sourcing


• Collaborate with cross-functional teams to gather requirements and translate them into technical specifications


• Mentor software engineers in best practices for scalable, service-oriented architectures


• Evaluate and recommend new technologies to enhance our technology stack


• Lead the adoption of container orchestration platforms (e.g., Kubernetes)


• Implement service discovery, load balancing, and circuit breaker patters


• Implement event-driven architectures when needed using message queues (e.g., Apache Kafka, RabbitMQ)

Required Qualifications

• Bachelor’s degree in computer science, Software Engineering, or related field


• 10+ years of experience in software development, with at least 5 years in software service architecture and development roles


• Extensive experience with microservices architecture, domain-driven design, and event-driven architecture patterns


• In-depth knowledge of distributed systems, API design, cloud computing, and scalability best practices


• Strong understanding of DevOps practices, CI/CD pipelines, and containerization technologies (Docker, Kubernetes)


• Experience with cloud platforms (AWS, Azure, or GCP) and their respective services for building scalable, fault-tolerant systems


• Strong proficiency in C#, Python, and JavaScript, with the ability to work across multiple languages


• Experience with SQL as well as both relational and NoSQL databases, including working knowledge of ORM technologies

Preferred Qualifications

• Experience in implementing observability solutions (logging, monitoring, and tracing) for microservice architectures


• Experience with service mesh technologies (e.g., Istio, Linkerd) for managing microservice communication


• Knowledge of serverless architectures and Function-as-a-Service (FaaS) platforms


• Exposure to the finance industry or with financial software systems


• Familiarity with Databricks and big data processing technologies


• Certifications in relevant cloud platforms (AWS, Azure, or GCP)

Key Competencies

• Strategic thinking and ability to align technical solutions with business and firm objectives


• Excellent communication skills, able to explain complex technical concepts to both technical and non-technical stakeholders


• Strong leadership and mentoring abilities


• Analytical and problem-solving skills with a focus on scalable, efficient solutions


• Adaptability and eagerness to learn new technologies and methodologies


• Attention to detail and commitment to code quality and best practices


• Ability to balance technical debt reduction with feature delivery and business priorities
