About Voltspan
Voltspan helps companies keep their data in their own hands and turn it into models of their own. We build from the power up: our own GPU clusters in US data centers, the sandboxes and inference agents run on, and the training behind them. We are growing across every layer of the stack.
About the role
Customers trust us with their data, their agents and their models. You will secure the whole stack, from the BMC on a server to the API in front of a model.
What you'll do
- Design isolation between customers across clusters, sandboxes and storage
- Build identity, access and secrets management for our platform
- Harden hardware, firmware and network edges in our data centers
- Lead compliance work such as SOC 2, and customer security reviews
What we're looking for
- Hands-on infrastructure or cloud security experience
- Strong understanding of Linux, networking and virtualization security
- Ability to write code, not only policy
Nice to have
- Experience running SOC 2 or ISO 27001 programs
- Hardware and firmware security
Projects you might work on
- Tenant isolation that holds up to an external red team
- A security program enterprise customers approve quickly

If a role excites you but you don't meet every qualification, apply anyway. We care more about what you have built than about a checklist.
Salary range, visa sponsorship and benefits will be added before this posting goes live.
How we work
- Small teams, big systems. Everyone here owns real infrastructure and real customers from week one.
- From volts to agents. Work moves across the whole stack, so you will see how your piece connects to power, GPUs, tokens and agents.
- We run what we build. The people who write the software also operate it, next to the people who rack the hardware.
