What’s Exciting About the Role

Verifone is seeking a Kafka DevOps Engineer to join our Platform Engineering team. This is an operations-first role with a strong emphasis on scripting, automation, and pipeline development. You’ll be hands-on with day-to-day Kafka operations, reliability, tuning, and high availability for payment gateway solutions that process billions of transactions annually on-prem and in AWS Cloud. Beyond keeping the lights on, you’ll play a key role in building the data pipelines—of which Kafka is a core component—that power Verifone’s new AI, machine learning, and analytics initiatives. You’ll also be part of an active effort to migrate Kafka and related services to Kubernetes, giving you hands-on experience with a meaningful infrastructure modernization project. The technology footprint is broad: Redis, MongoDB, PostgreSQL, MySQL, Snowflake, and more—so you’ll grow well beyond a single-technology niche.

Key Responsibilities

Kafka Operations & Reliability

  • Manage and support Apache Kafka clusters (including MSK), Kafka Connect ecosystem, and KSQL for high-throughput, fault-tolerant messaging and event streaming pipelines.
  • Monitor system health, set up alerts, and drive incident response and root cause analysis (RCA).
  • Handle day-to-day operational tasks including offset management, lag monitoring, consumer group management, and cluster rebalancing.
  • Perform routine cluster maintenance: upgrades, configuration changes, scaling, and health checks.

Scripting, Automation & DevOps

  • Develop and manage automation scripts using Python and Shell scripting to reduce manual toil and improve operational efficiency.
  • Design, implement, and maintain robust CI/CD pipelines for patching automation.
  • Build and maintain Infrastructure as Code (IaC) using tools such as Terraform, Ansible, or similar.
  • Containerize and orchestrate workloads using Docker and Kubernetes, with the opportunity to help migrate Kafka and related services to Kubernetes.

 

Data Pipeline Development

  • Build and optimize end-to-end data pipelines, with Kafka as a core streaming component alongside batch and ETL processes, enabling new AI, ML, and analytics use cases.
  • Collaborate with development teams to implement best practices for data flow, security, scalability, and performance.
  • Continuously identify and implement improvements to the software development lifecycle (SDLC).

Cloud & Infrastructure

  • Manage cloud infrastructure on AWS (VMs, networking, storage, IAM, etc.).
  • Support cloud migration tasks and assist in moving workloads between on-prem and cloud environments.

Required Qualifications / Skills

  • 4+ years of overall engineering experience with 2+ years of hands-on experience supporting Kafka infrastructure in a large-scale production environment.
  • Kafka Producer/Consumer microservices concepts and Kafka distributed architecture.
  • Solid Linux fundamentals: networking basics, logs, system troubleshooting, process/memory, disk.
  • Strong scripting and automation skills (Python, Bash) with a track record of reducing operational toil.
  • CI/CD pipeline development and Infrastructure-as-Code experience (Terraform preferred).
  • Cloud engineering skills, preferably AWS (EC2, VPC, IAM, MSK/ElastiCache, CloudWatch).
  • Familiarity with observability tools (metrics/logs/tracing concepts) and incident response practices.
  • Basic understanding of distributed systems tradeoffs (availability, consistency, partitions, backpressure).
  • Strong communication and presentation skills with emphasis on executive communication.
  • Flexible with regards to working shifts; on-call and weekends.

Preferred Skills (Highly Desired)

Data Engineering & Pipelines

  • Data engineering skills including data analytics, data processing, ETL, and data lake technologies (batch and streaming, file formats like Parquet, table formats like Iceberg/Delta/Hudi, basic orchestration).
  • Experience with AWS data tools (Athena, Glue, Iceberg, Redshift, etc.).
  • Exposure to Kafka Streams, Apache Flink, or similar stream processing frameworks.

Database & Caching Technologies

  • Operate Redis deployments for caching, ephemeral state, queues/streams, and rate limiting use cases.
  • Relational DB experience: PostgreSQL and/or MySQL (indexing basics, vacuum/analyze, query plans, replication fundamentals).
  • MongoDB operational familiarity (replica sets, elections, oplog basics, backup/restore).

Infrastructure & Security

  • Container/Kubernetes familiarity (deployments, stateful workloads, storage classes).
  • On-prem experience (VMware/KVM, storage, networking).
  • Security fundamentals: least privilege, secrets management, encryption-in-transit/at-rest concepts.
  • Experience working with PCI (Payment Card Industry Data Security) standards.

What We Offer

  • Direct impact on Verifone’s global payment infrastructure—your work keeps billions of transactions flowing reliably every year.
  • Ground-floor involvement in building the data pipelines that will drive Verifone’s AI, machine learning, and analytics strategy.
  • Hands-on participation in a Kafka-to-Kubernetes migration—a resume-building modernization project from day one.
  • Multi-technology exposure—Kafka, Redis, MongoDB, PostgreSQL, MySQL, Snowflake—so you grow as a well-rounded platform engineer, not a single-tool specialist.
  • Mentorship from senior engineers and Kafka architects with deep production experience.
  • Clear career progression path from mid-level to senior and lead engineer.
  • Funded certification paths—Confluent (CCDAK, Certified Administrator), AWS (Solutions Architect, MSK Specialty), CKA—plus budget for courses and technical conferences.
  • Hybrid/remote working flexibility with a collaborative team culture.
  • Competitive compensation with performance-based incentives.
