Software Development Engineer (New Grad / Entry Level)

Qumulo·Junior·Hybrid · Seattle·$110k–$140k USD

Posted Oct 4, 2026·qumulo.com

Qumulo is a software-defined cloud data platform. Our core is a distributed storage operating system in C & Rust, holding exabytes in the datacenter, at the edge, and natively in the cloud. Qumulo serves everything from a hospital's medical imaging archive to an animation studio's render farm in an environment where 99% correct doesn’t cut it.

About the Role:

Joining us, you'd learn and work across our distributed storage engine and the services that help customers store, manage, and protect their data, under the guidance of experienced senior engineers.

This includes a fault-tolerant block layer that erasure-codes and distributes data beneath the file system, a transactional file system where aggregates roll up as they change so a query across billions of files answers in real time instead of walking a tree, and that same machinery drives quotas, capacity trends, snapshot policy, multiple access protocols, plus replication and backup - all running in userspace.

All of which makes Qumulo a distributed operating system problem: scheduling, memory hierarchy, protection, and concurrency. We're AI-forward and specific about what that means. You will learn to use agents to help write code while developing your engineering judgment to ensure every design decision is correct, because nothing ships that isn't right.

Why join Qumulo:

Qumulo blends the flexibility of a startup with the security of a mature and profitable organization. Here you’ll work closely with a small team of smart, capable engineers who will serve as your mentors. Opinions are expected, disagreement is normal, and you'll get hands-on experience taking projects from ideation to release. We value quality, correctness, and performance. Our architecture, protocols, and patents are public, so you can read how most of this works before you talk to us - and we’re small enough that the work you do will actually show up in the product.

As a Software Engineer at Qumulo, you will:

Collaborate with team members on design, code reviews, and pair programming to deliver high-quality software.
Collaborate with team members and area leads on architecture and design of new/updated features.
Contribute to full-lifecycle feature development and testing using C, Rust, and Python.
Take ownership of defining and implementing customer-facing features and internal system improvements.
Help debug, troubleshoot, and fix test failures and complex product or service issues in production environments.

What we're looking for:

Recently graduated (or graduating within the next 9 months) with a degree in Computer Science, a related field, or equivalent experience.
Ability to write well-factored, maintainable, and well-tested code.
Strong grasp of algorithms and data structures, with solid academic or project experience in distributed systems, database concepts, concurrent programming, or operating systems concepts.
