• Design and execute A/B tests, causal inference analyses, and other experimentation frameworks.
• Analyze product requirements and map them into technical tasks.
• Execute development projects through full software development life cycle.
• Optimize and manage various database solutions, including NoSQL (MongoDB, ElasticSearch, Hadoop), in-memory databases (MemSQL, Apache Ignite), and relational databases (Oracle, MySQL).
• Ensure high-quality deliverables by adhering to software development best practices, testing, and continuous integration pipelines.
• Collaborate with cross-functional teams to deliver end-to-end features from UI to backend services.
• Develop responsive, user-friendly interfaces using React JS or similar UI frameworks.
• Integrate front and back-end components to ensure seamless functionality and user experience.
• Identify, analyze, and remediate security vulnerabilities across applications and environments.
• Write advanced SQL queries to extract, manipulate, and validate large datasets.
• Build predictive models using Python or R, applying best practices in statistical modeling.
• Participate in code reviews, design discussions, and architectural decision-making.
• Ensure adherence to best practices in coding, performance tuning, and security.
• Any other duties as assigned by superiors.

Requirements

Qualifications & Experience:

• Full Grade 12 Certificate with 5 credits; including English and Mathematics.
• Bachelor’s or Master’s degree in Computer Science, Software Engineering, or Information Technology. A background in Mathematics or Statistics is a major plus given the Data Science requirements.
• At least 7-10 years of professional software development experience, with at least 2-3 years in a Lead Developer or Software/Coding Architect role.
• Experience in designing highly scalable data processing pipelines.
• Experience with designing and developing APIs with low response times and resource utilization for large data sets.
• Hands-on experience with React JS or Next JS.
• Experience with OWASP principles, API security (OAuth2/OpenID Connect), and data encryption.
• Experience building ETL (Extract, Transform, Load) processes or using tools like Hadoop.
• Prior experience in FinTech or Banking is critical.
