Mulga builds Spinifex, an open-source, AWS-compatible cloud you run on infrastructure you control. Built for defence, taken to enterprise and AI. Founded across Australia and the US: company HQ in Austin, Texas; engineering HQ on Sunshine Coast, Australia.
We didn't copy the API. We rebuilt the engineering underneath it. Most "AWS alternatives" hand you a rewrite. We don't. On Spinifex your apps and AI get a clean lift and shift. They won't even know they left.
Most AWS alternatives wrap an API and call it a cloud. We engineered the parts that are actually hard: distributed object storage with erasure coding, block storage built to survive failure, compute on bare metal. That depth is the reason your software runs unchanged, instead of rewritten.
We started Mulga because the software the world depends on was built for AWS, but the places that matter most aren't in an AWS region. Defence sites, sovereign data centres, edge facilities, Neoclouds: all running cloud-native workloads with no cloud-native place to put them.
Spinifex closes that gap. It's an open-source build that speaks the AWS API surface (EC2, S3, EBS, VPC, IAM) on whatever hardware you put it on. AGPL-3.0, auditable, yours to keep.
The next decade of cloud belongs to whoever lets you keep both your software AND your sovereignty. Cost, jurisdiction, latency, control: every one of these is pulling workloads off the hyperscalers, and the gravity isn't reversing.
We believe the right answer isn't a new closed cloud. It's an open AWS-compatible surface that runs wherever you need it, owned by whoever runs it. The infrastructure you depend on shouldn't depend on a vendor for its right to exist.
That's what Spinifex is, and the engineering is the moat. Anyone can wrap an API. Almost nobody can rebuild the storage, the block layer, and the compute fabric underneath cleanly enough that workloads written for AWS just work. That's the work we're doing, and we're doing it in the open.
Open core, real engineering, no next lock-in. The platform you bet on should outlive any single company, including ours.
We're a distributed team building operator-grade infrastructure software in the open. If you've shipped serious distributed systems, built cloud control planes, or done deep work in storage, networking, or virtualisation, we want to talk to you.
Specific roles coming soon. For now we're hiring senior engineers across the stack.
Two offices: Austin, Texas (company HQ) and Sunshine Coast, Australia (engineering HQ), plus remote collaborators in between. Weekly cadence, strong written culture.
Neoclouds, OEMs, defence integrators, ISVs running on AWS who need their product to land off-cloud, say hi.
If you've got an AWS workload that needs to leave AWS or go to the edge, we'd like to know what you're trying to do.
