Continuously research, evaluate, and prototype emerging open-source data and streaming technologies, leading their integration into Citi's data platform through direct implementation. This includes evaluating new streaming frameworks and caching solutions.

• Performance & Resilience Optimization:

Proactively identify and implement architectural and systemic performance optimizations to ensure optimal efficiency, responsiveness, and resilience across the entire data platform, including Flink and Redis clusters.

• Cross-Functional Technical Collaboration:

Collaborate closely with senior technical stakeholders across engineering, data science, and business teams to translate complex technical requirements into robust, high-impact implementations.

• Delivery & Code Quality Assurance:

Drive the timely, high-quality, and secure delivery of data platform features, championing agile methodologies, engineering best practices, and ensuring accountability for code quality and robust testing.

• Technical Problem Solving:

Act as a primary escalation point for complex technical challenges, providing expert diagnosis and hands-on resolution.

• Operational Flexibility:

May occasionally work a non-standard shift including nights and/or weekends and/or have on-call responsibilities to support critical platform operations.

Qualifications:

• 10+ years of demonstrable and highly hands-on experience in software development, with at least 3-5 years in a lead technical contributor or staff engineer role within a data-intensive environment.
• Deep Architectural & Implementation Expertise:

Proven expertise in designing, building, and implementing Microservices and complex streaming/data pipeline architectures.

• Polyglot Proficiency & Technical Authority:

Demonstrated ability to be a technical authority and actively contribute across multiple programming languages/frameworks, with strong hands-on experience in Java (Java 11+ preferred), and significant expertise in Python, along with practical knowledge of front-end technologies like Angular/React.

• Expertise in Flink Ecosystem:

In-depth architectural understanding and hands-on experience with Apache Flink for real-time stream processing, including Flink SQL, Data Stream API, and state management. Comprehensive knowledge of Flink infrastructure setup, maintenance, enhancement, migration strategies, and experience in evaluating/integrating alternative streaming frameworks.

• Mastery of Redis:

In-depth knowledge and practical experience with Redis, encompassing not only data structures, caching patterns, and pub/sub mechanisms but also strategic expertise in Redis cluster setup, maintenance, enhancement, and migration strategies for mission-critical, high-performance applications.

• Distributed Systems & Data Engineering:

Deep understanding of distributed systems concepts and extensive hands-on experience with data distribution platforms like Apache Kafka, and various big data storage/querying systems (e.g., Trino, Pinot, Druid, Ignite) for low-latency access in large-scale, distributed data pipelines.

• Cloud-Native & DevOps Contribution:

Proven experience with the design, implementation, and operational aspects of cloud-native applications and deployment via Kubernetes / Open Shift / ECS, specifically for managing microservices, streaming, and data services.

• Technical Leadership, Coaching & Communication:

Exceptional ability to provide technical direction, coach junior engineers through hands-on collaboration, and articulate complex technical concepts clearly to diverse audiences.

• Advanced Problem Solving & Strategic Technical Thinking:

Excellent problem-solving skills, a data-driven approach to technical decision-making, and the ability to define and execute long-term technical strategies through direct implementation.

• Experience with Large Language Models (LLMs), including fine-tuning, prompt engineering, and integrating LLMs into applications, is a plus.

Software Engineering Excellence:

• Demonstrable experience driving and implementing CI/CD strategies for rapid, reliable, and secure deployment of microservices and streaming components. Familiarity with Team City, Sonar Qube, and Jenkins.
• Expertise in the SDLC lifecycle within an Agile environment, adapting to fast-paced data requirements and directly contributing to continuous process improvement.
• A champion of engineering best practices: architectural patterns, coding standards, rigorous code review, and robust unit/integration testing across diverse technologies.
• Strong experience with standard CI tools (Jenkins, Team City, Sonar Qube, Git).

Education:

• Bachelor’s degree/University degree or equivalent experience.
