- Hands-on Development: Actively participate in the coding, implementation, and peer review of complex modules and core framework components to lead by example.
- Strategic Solutioning: Translate complex business requirements into robust, secure, and efficient technical solutions, setting the standard for the engineering organization.
- Code Excellence: Champion and enforce best practices for writing modular, testable, and maintainable code, rooted in expert knowledge of OOP principles and design patterns.
- System Optimization: Lead efforts to continuously refactor and optimize applications for performance, scalability, and maintainability at an enterprise scale.
- High-Level Collaboration: Collaborate with senior stakeholders, product owners, and other technology leaders to define roadmaps and ensure high-quality delivery.
- Innovation: Drive the evaluation and adoption of new technologies and methodologies to keep the platform at the cutting edge.
- Influence and Leadership: Provide thought leadership and influence technical design and decisions across the organization.
Recommended Qualifications:
- 10+ years of hands-on experience in Big Data development, with expert-level proficiency in Java and Apache Spark.
- Domain Knowledge: Strong understanding of Funds Transfer Pricing (FTP) processes and financial systems is required.
- Expert-level knowledge of object-oriented programming, advanced design patterns, and clean coding practices.
- Proven track record of architecting, building, and optimizing large-scale, mission-critical distributed data processing systems.
- Extensive experience with REST APIs, RDBMS, and Kafka or similar messaging systems.
- Deep experience with microservices architecture and containerization technologies (Docker/Kubernetes).
- Significant experience working in and leading teams within Agile environments, demonstrating strong collaboration and ownership.
- Proven ability to lead technical teams and mentor engineers to achieve technical excellence.
- Extensive experience with Databricks is highly preferred.
- Deep familiarity and experience with building AI-powered solutions / AI agents.
