Now hiring technology partners

Projects open for software collabs

We are looking for Technology Partners to work alongside us on the 3 projects below.

Timing: Now. Start asap to deliver projects by EOY2026.
Cubbit engineering team (20+ devs) supplies full support to make the Partner autonomous.
01

Kubernetes Operator for the Cubbit DS3 Coordinator

Required skills
Kubernetes Operator development in Go DevOps Systems administration
Replace the per-customer Pulumi/ArgoCD fork with one reusable Operator for the Coordinator's 12 Go microservices.
Handle always-on dependencies (Redis, Postfix) and orchestrate operator-managed ones (Kafka, Postgres, Prometheus — the latter two optional).
Bonus: a kubectl plugin for seamless install and management, fitting Cubbit's existing operator ecosystem.
Read the full brief

We want to develop a Kubernetes Operator that simplifies the deployment of the Coordinator component, currently installed through a Pulumi script and an ArgoCD deployment. The present approach forces us to maintain a fork of the values repository for each customer, which makes installation cumbersome for the end user. The Coordinator consists of twelve microservices written in Go, whose configuration and Helm chart will most likely need to be reworked. The operator will need to handle the installation of the dependencies that are always present, namely Redis and Postfix, as well as the orchestration of those that already ship with their own operator, such as Kafka, Postgres and Prometheus, of which only Postgres and Prometheus are optional since they are sometimes managed directly by the customer. Ideally, we also envision a kubectl plugin to make installation and management as seamless as possible. It is worth noting that Cubbit already relies on other Kubernetes operators to install the many other components of the platform, so this work will fit into an established operational ecosystem.

Technical audit and hardening of DittoFS (open source)

Required skills
Golang NFS & SMB — Linux NFS & SMB — Windows / Active Directory
DittoFS serves NFSv3/v4 and SMB2/3 in userspace — no FUSE, no kernel modules — with dedup, compression and client side encryption over S3 compatible backends.
Built over eight months, almost entirely with AI — now needs a careful human code audit before wider production use.
Focus areas: sustained-write reliability tests, SMB/NFS permission correctness, removing unnecessary AI-authored code, and performance.
Read the full brief

DittoFS (github.com/marmos91/dittofs, dittofs.io) is a modular virtual filesystem written in Go, capable of serving NFSv3/v4 and SMB2/3 simultaneously in userspace, without relying on FUSE or kernel modules, across interchangeable backends including S3 compatible storage. It integrates deduplication, compression and client side encryption. The project was built over the course of eight months, almost entirely with the support of AI, and it is attracting growing interest from teams looking to run it in production. The product works, but we need someone to read through the code carefully, carry out a technical audit and support us in maintaining the open source repository. In particular, we expect the introduction of reliability tests based on sustained, continuous writes over time, verification of the semantic correctness of permissions between SMB and NFS, the removal of unnecessary code introduced by the AI, and an overall effort to improve performance.

03

Technical audit and development support for Cubbit DS3 Drive

Required skills
Mobile & desktop app development Swift Kotlin C# Rust
Rust core with FFI bindings for Swift, C# and Kotlin — macOS and iOS are complete, Windows is in development.
Next up: finish Windows, then build Android and web on each platform's native APIs (e.g. Apple's FileProvider).
Requested gaps: versioning, proxy support, audit logs, whitelabeling, email folder sharing, and large-file sharing via an Outlook plugin.
Read the full brief

We are also seeing strong interest in building a whitelabel, cross platform version of the Cubbit DS3 Drive application (github.com/marmos91/cubbit-ds3-drive), which was likewise developed with the help of AI. The application is built on a Rust core that, through FFI, generates the bindings for Swift, C# and Kotlin, supporting macOS, iOS, Windows and Android. The macOS and iOS versions are complete and fully functional, while the Windows version is currently in development. On this front we need to complete the Windows version, implement the Android and web versions, and fill a number of product gaps requested by our customers, specifically versioning, proxy support, audit logs, whitelabeling, folder sharing via email, and sharing of large files through an Outlook plugin. Each platform will need to build on the native APIs offered by its respective operating system, such as Apple's FileProvider APIs. Here too, we expect the partner to begin with an audit of the existing code, in order to ensure it is clean, efficient and reliable.
