Overview

As a Senior Software Engineer, you’ll play a key role in shaping how modern organizations build and secure software at scale. You’ll join a collaborative, forward-thinking team and help drive our mission to embed security into every part of the AI-native development lifecycle.

You’ll join a team of exceptionally strong and talented engineers who are the backbone of our data infrastructure.

• Conducting performance tuning, monitoring, and troubleshooting of Kafka clusters and data pipelines to maintain operational excellence.
• Collaborating with engineering teams to understand data needs and enable them to build reliable, high-throughput applications on top of our platforms.
• Leading technical projects, mentoring junior engineers, and contributing to the technical roadmap of the team.
• Staying ahead of industry trends and evaluating new technologies to continually improve our data infrastructure.

What You’ll Need

• At least 5 years of commercial experience as a Software or Platform Engineer, with a strong focus on data infrastructure.
• Hands-on production experience with Kafka, including cluster administration, security (SSL, SASL, ACLs), and performance optimization.
• Extensive experience with Infrastructure as Code, particularly Terraform.
• Understanding of distributed systems architecture, including fault tolerance, message ordering, and partition strategies.
• Proficiency in at least one core programming language (Go or TypeScript), and willingness to learn new languages and technologies.
• Experience with cloud platforms (AWS, GCP, or Azure), especially data-related services.
• Experience with data warehousing concepts and tools, specifically Snowflake.
• A track record of building and operating reliable, scalable back-end systems.
• Strong commitment to code quality, testing, and operational excellence.
• Excellent communication and collaboration skills, with the ability to work with diverse technical teams.

Nice to Have

• Experience with Snowflake, Kafka, and Terraform.
• Experience with Kubernetes in production.
• Experience with other Kafka ecosystem tools like Schema Registry and Kafka Connect.
• Passion for data and solving large-scale technical problems.
