Mary Technology builds AI for litigation lawyers. It reads every document in a case, turns the evidence into facts linked back to the exact page, and flags what conflicts and what’s missing. Work that used to take a legal team weeks now takes minutes.

More than 4,000 lawyers across 150+ firms use it. We raised a $7M round led by OIF Ventures in March 2026 and now have offices in Sydney, Austin and San Francisco.

We’re hiring our first dedicated Platform Engineer. You’ll own our cloud infrastructure end to end, working closely with engineering and product, and build the practice from the ground up with room to grow a team around you.

What you’ll be doing

- Running GPU infrastructure for AI inference across AWS, Azure and GCP as usage grows
- Taking the platform global, extending our Terraform setup into new regions
- Designing observability and on-call from scratch, so we find issues before customers do
- Owning the security setup behind SOC 2, which is what wins us deals with law firms
- Owning CI/CD pipelines in GitHub Actions
- Automating provisioning, scaling and configuration to cut out manual work
- Shaping how we run AI agent infrastructure,



ephemeral environments and model telemetry as deployment scales

Why join Mary?

- First infrastructure hire at a company already used by thousands of lawyers
- Real AI workloads in production, with GPU capacity growing quick
- Legal data is about as sensitive as it gets, so security work is central to the business
- A direct say in how the platform gets built as we expand into the US
- Equity with real upside and an attractive salary in a scaling, AI native business

What you’ll bring

- Experience in DevOps, Cloud or SRE roles, with strong software engineering fundamentals
- Comfortable owning infrastructure from design through to maintenance
- Terraform or similar infrastructure as code tools
- Hands-on CI/CD experience, ideally GitHub Actions
- Solid AWS knowledge; Azure or GCP is a plus
- Scripting in Python and Bash
- Good understanding of cloud security: IAM, encryption, vulnerability scanning, monitoring
- Docker and Kubernetes experience is a plus
- Interest in AI infrastructure is a plus, though not required

Sound like you? We’d love to hear from you.
