Job description

Overview

lakeFS is an open source project that provides the object storage a manageability layer with version control capabilities such as branching, committing, merging and using pre-commit and pre-merge hooks. This allows data engineers to manage the data lake securely, just like the code repository they manage. We are on a mission to simplify the lives of engineers building data-intensive applications.

What you'll do

• Design and develop robust backend services that power lakeFS, written primarily in Go.
• Contribute to our React-based UI to deliver intuitive and reliable user experiences.
• Work across our stack: cloud-native infrastructure (Kubernetes, Terraform, ArgoCD), data engineering plugins and SDKs (Scala, Python, Java), and performance-critical components such as Graveler.
• Ensure our product remains reliable, scalable, and secure in production — handling billions of daily API calls across multiple clouds.

BUILD OUR TEAM

• Collaborate closely with teammates in a distributed, remote environment.
• Contribute ideas and feedback to shape product direction based on customer and community input.
• Help foster a culture of trust, ownership, and continuous learning.

Requirements

• 7+ years of experience in backend development, preferably building distributed or cloud-native systems.
• Proficiency in Go (preferred) or similar backend languages (Java, Python, etc.).
• Familiarity with modern frontend development, specifically React.
• Strong grasp of data structures, system design, and software architecture principles.
• Experience working in remote teams and excellent written and verbal communication skills.
• Passion for open source, data infrastructure, and empowering engineers.
• A BSc/MSc in Computer Science (or similar) – A plus.
