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 recent 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 solid 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.
