You will collaborate closely with Product, Operations, and DevOps teams to develop secure, scalable, and efficient solutions in a fast-paced environment.

Key Responsibilities

Architect and implement cloud-based services

• Design, develop, and maintain card platform services using AWS (e.g., EC2, RDS, Lambda, S3) and Python.
• Utilize AWS CDK (Cloud Development Kit) to provision and manage cloud infrastructure resources that support data engineering and processing workflows.

Develop and manage data pipelines and ETL processes

• Automate ETL workflows and data processing tasks in Python and TypeScript, ensuring high data quality and integrity.
• Manage data integration from various sources into the data warehouse.

API integration and development

• Design and consume RESTful APIs to integrate with both third-party and internal applications.
• Manage real-time and batch data flows using AWS services, ensuring optimal performance and reliability.

Optimize and manage databases

• Work with relational databases like MySQL to design schemas, optimize queries, and conduct data migrations.
• Troubleshoot, debug, and enhance existing systems to ensure high availability and security.

Ensure scalability, reliability, and security

• Develop highly scalable, secure solutions aligned with AWS best practices, including monitoring and cost optimization.
• Implement and maintain CI/CD pipelines and other DevOps practices to streamline deployments.

Collaborate across teams

• Work closely with product managers and other stakeholders to translate business needs into technical requirements.
• Align data processes with broader product goals to drive efficiency and effectiveness.

Provide technical leadership

• Guide architectural decisions, including tool and technology choices for the card platform.
• Mentor junior and mid-level engineers, sharing knowledge on systems design, coding best practices, and cloud infrastructure.

What We’re Looking For

• Five or more years of software engineering experience, preferably with large-scale, data-intensive platforms.
• Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field—or equivalent work experience.
• Proficiency in Python for building enterprise-scale applications and services.
• Working knowledge of TypeScript for cloud development and automation tasks (preferred).
• Strong experience with AWS (e.g., Lambda, EC2, RDS, Step Functions, S3) and cloud-based architectural design.
• Familiarity with AWS CDK for provisioning and managing cloud infrastructure.
• Experience with MySQL or other relational databases (schema design, query optimization, data migration).
• Hands-on experience with ETL processes and data pipelines, including ingestion, transformation, and validation.
• Knowledge of DevOps principles and tools (CI/CD pipelines, Docker, Kubernetes) is preferred.
• Experience in FinTech or restricted-spend payments is a plus.
• Strong analytical and problem-solving skills, with the ability to optimize and troubleshoot cloud-based workflows.
• Excellent communication and collaboration skills to work effectively across multiple teams.

Why Join Us?

• Work on cutting-edge FinTech solutions that make a real-world impact.
