Software Engineer - Backend

About the Team

The Clumio backend team designs, builds, and operates the cloud-native systems behind Clumio's data protection solutions — from the core SaaS platform to the systems that back up and recover large volumes of enterprise cloud data. In these environments backup is a compliance-, audit-, and security-driven requirement rather than a nice-to-have, so recovery performance, cost efficiency, and reliable operation at scale are our key differentiators.

Built on a fully cloud-native architecture, the platform scales dynamically with workload, delivers faster recovery and lower cost than native cloud backup, and stays correct under real-world failure conditions through reprocessing and retries. Beyond core backup and recovery, the team also builds customer onboarding, metering and billing, reporting, alerting, and ML-driven insights. We operate a mature, production-proven platform on AWS — including Amazon S3, DynamoDB, and the industry's first data protection solution for Apache Iceberg — and are actively expanding into multi-cloud data protection across GCP and Azure.

Role Overview

As a Software Engineer on the Clumio backend team, you implement and deliver features and components within the data protection platform, working under the guidance of Senior and Principal Engineers. This role focuses on writing reliable, maintainable, production-ready code as part of larger systems that are critical to customer-facing operations.

You take problems from implementation through to production — building features and workflows, writing tests, and helping operate and improve them once they ship. You make sound implementation decisions within an established design, learning to balance correctness, simplicity, and performance, and you grow your ownership of specific components over time.

This is a role built for growth. You'll learn how large-scale, cloud-native data protection systems are designed, operated, and kept correct under real-world failure — working on problems of genuine scale rather than toy projects. With close mentorship from Senior and Principal Engineers and regular code review, you'll sharpen your engineering fundamentals, take on steadily larger and more complex work, and grow along a clear path toward broader system ownership.

Basic Qualifications

• Software engineering experience through professional roles internships, or academic and personal projects.
• Solid grounding in computer science fundamentals — data structures, algorithms, and complexity analysis — with the ability to apply them to practical problems.
• Proficiency in at least one modern programming language (e.g., Go, Java, Python, C++, Rust).
• Ability to break a problem down into a correct, maintainable solution, and the instinct to ask clarifying questions when requirements are unclear.
• A willingness to learn how production systems are built, operated, and debugged, with support from the team.
• Working knowledge of English.
