Senior Kafka Developer information

What does a senior Kafka developer do?

A Senior Kafka Developer is responsible for designing, developing, and maintaining systems that use Apache Kafka for real-time data streaming and processing. They work on building scalable data pipelines, integrating Kafka with other systems, and ensuring high availability and performance. Additionally, they often provide technical leadership, mentor junior developers, and help define best practices for event-driven architectures within an organization.

What are some common challenges senior Kafka developers face when managing large-scale data streaming pipelines?

Senior Kafka Developers often encounter challenges such as ensuring data consistency across distributed systems, optimizing Kafka cluster performance, and monitoring for bottlenecks or data loss. Managing schema evolution and handling message serialization can also be complex, particularly in environments with multiple producers and consumers. Collaborating closely with DevOps, data engineering, and application development teams is essential to proactively address these issues and maintain high system reliability.

What are the key skills and qualifications needed to thrive as a senior Kafka developer, and why are they important?

To thrive as a Senior Kafka Developer, you need deep expertise in distributed systems, stream processing, and strong programming skills in languages like Java or Scala, typically backed by a relevant degree and significant experience with Apache Kafka. Familiarity with Kafka Connect, Schema Registry, monitoring tools, and cloud platforms, as well as certifications like Confluent Certified Developer, are highly valuable. Exceptional problem-solving, communication, and collaboration skills help you design scalable solutions and work effectively with cross-functional teams. These skills ensure the reliability, performance, and scalability of critical data infrastructure that powers real-time business operations.

What is the difference between Senior Kafka Developer vs Kafka Engineer?

AspectSenior Kafka DeveloperKafka Engineer
Primary FocusDesigning, developing, and optimizing Kafka-based applicationsImplementing, maintaining, and scaling Kafka infrastructure
Required SkillsKafka API, Java/Scala, data streaming conceptsKafka setup, cluster management, performance tuning
CertificationsKafka certifications, Java certificationsKafka certifications, DevOps certifications
Work EnvironmentDevelopment teams, data engineering projectsOperations, infrastructure teams, cloud environments

While both roles require Kafka knowledge and related certifications, Senior Kafka Developers focus on application development and data integration, whereas Kafka Engineers concentrate on infrastructure, deployment, and system performance. The roles often collaborate but serve different aspects of Kafka implementation within organizations.

Job description

Citi is hiring a Senior Java Engineer to lead the technical transformation of its global cheque payment platform - a critical infrastructure at the heart of high-volume financial transaction processing. In this senior engineering role within the Payments Platform organisation, you will combine deep hands-on coding in Java with platform strategy ownership, guiding a scrum team through the modernisation of core payment systems from legacy mainframe architectures to cloud-native microservices. This is a rare opportunity to architect and deliver at scale while embedding AI-driven practices into both the platform and the engineering workflow.
Responsibilities
  • Design and build production-grade Java microservices for a high-volume, low-latency cheque payment platform, authoring reusable frameworks, conducting architecture reviews, and setting the technical standard for the team.
  • Architect event-driven, fault-tolerant distributed systems using Apache Kafka - covering message schema design, topic partitioning, consumer group strategies, and exactly-once processing semantics.
  • Define and execute the engineering roadmap for modernising the cheque payment platform, migrating global components from monolithic mainframe applications to scalable, cloud-native microservices.
  • Own the platform's data architecture across Oracle, Microsoft SQL, and MongoDB - governing schema design, query optimisation, indexing strategies, and data consistency patterns across relational and NoSQL stores.
  • Drive AI-powered engineering quality across the team - integrating tools such as GitHub Copilot and LLMs (including Gemini) for automated test generation, vulnerability scanning, and enhanced payment processing accuracy.
  • Lead performance engineering for JVM-based applications - profiling hotspots, tuning garbage collection, optimising thread management, and improving critical settlement processing paths.
  • Own the security and compliance posture of the platform through threat modelling, vulnerability assessments, and secure design reviews, ensuring alignment to engineering excellence standards across CI/CD, DevOps, and cloud-native delivery.
  • Act as the primary engineering point of contact for the cheque processing pillar, communicating platform health, delivery progress, and engineering strategy to senior business and technology stakeholders.

Required qualifications & skills
  • Extensive hands-on Java engineering experience in high-throughput, production-grade environments, including JVM performance tuning, GC optimisation, and thread and memory profiling.
  • Proven ability to design and deliver microservices-based architectures using Spring Boot or Spring MVC, with hands-on expertise in RESTful API design, service decomposition, and inter-service communication patterns.
  • Deep practical knowledge of Apache Kafka, including topic design, partitioning strategies, consumer groups, exactly-once semantics, and high-throughput stream processing.
  • Hands-on expertise with Oracle SQL and MongoDB, covering schema design, query optimisation, indexing, aggregation pipelines, sharding, and replica set configuration.
  • Cloud-native engineering experience with OpenShift, AWS, Kubernetes, and Docker - including container orchestration, autoscaling, and cloud-native deployment practices.
  • Hands-on ownership of CI/CD pipelines using tools such as Jenkins, Gradle, and Maven, with experience in DevOps practices, observability tooling such as Grafana, and distributed tracing.
  • Demonstrated experience delivering at scale within Agile or SAFe frameworks, including PI planning, cross-team dependency management, and programme-level governance.

Beneficial skills & qualifications
  • Familiarity with real-time ML model serving, MLOps practices, RAG patterns, or agentic AI frameworks such as LangChain or AutoGen in an enterprise or regulated environment.
  • Experience leading large-scale legacy modernisation programmes - migrating mainframe components written in COBOL, Assembler, or C++ into cloud-native microservices.
  • Hands-on Python skills applied to data pipeline engineering, AI and ML integration, and workflow automation.
  • Knowledge of reconciliation and exception handling patterns within payment settlement workflows.
  • Experience with chaos engineering, fault injection, and production readiness reviews as part of a resilience testing practice.

What we offer
Joining Citi means taking ownership of engineering that operates at genuine global scale. This role offers the platform, the people, and the technical challenge to do your most impactful work - with the seniority and visibility to shape how payments engineering evolves at one of the world's leading financial institutions.
  • Technical leadership at scale, with end-to-end ownership of a mission-critical global payment platform and clear senior visibility across technology and business.
  • A hands-on engineering culture that values technical depth at every level of seniority - you will stay close to the code while driving platform strategy.
  • Access to cutting-edge tooling, cloud-native infrastructure, and AI-powered development practices as part of a major payments modernisation programme.
  • Hybrid working model with 3 days in the office and 2 days working remotely, offering flexibility alongside strong team collaboration.
  • Structured learning and development opportunities to deepen expertise in distributed systems, AI integration, and financial technology at enterprise scale.
  • Competitive financial wellbeing package, including salary, performance-based reward, and a comprehensive suite of employee benefits.
  • Access to wellbeing and family support programmes designed to help you perform at your best inside and outside of work.

Build the future of global payments engineering at Citi - apply today and bring your expertise to a platform that moves the world's money.
