About Ojin
Ojin is The Human AI Company. We build the infrastructure that makes AI feel human. Our Human Agents deliver natural, lifelike conversations in real time, powered by our proprietary models and blazing-fast APIs on a globally distributed GPU fabric.
We've built award-winning AI experiences for brands including BMW, H&M, and Clinique. Now we're opening that infrastructure up as a platform that will define how the world experiences AI and we're assembling a small, ambitious team of exceptional people to do it.
The Role
At Ojin , the infrastructure underneath our product is what makes it exceptional - real-time AI at scale only works if the systems powering it are built right. This is the person who owns that.
You'll manage GPU deployments at scale across multiple clouds and regions, architect the systems that make real-time AI possible, and set the technical direction for how we build and scale as the platform grows. You'll also take a leadership role in some of our most important cross-functional work - including driving our compliance and security certifications - where your ability to coordinate across teams matters as much as your technical depth.
If you want to own hard problems end-to-end and shape how a fast-moving AI company builds its infrastructure from the inside, this is the role.
What You'll Do
Manage large-scale deployments of thousands of concurrent GPU servers, with a sharp focus on performance and efficiency
Architect and implement systems for dynamic deployment, routing, and load balancing across multiple clouds and regions
Design and implement deployment pipelines that are scalable, reliable, and actually a pleasure to work with
Set technical direction for infrastructure decisions and raise the bar for how the team builds and operates
Champion simple, robust tooling - research it, document it, and drive adoption across the team
Own observability and monitoring so we always know what's happening and can move fast when something isn't right
Lead our compliance and security certification work including SOC2 Type II - coordinating across engineering, product, and operations to get it done without it becoming a full-time job in itself
Build software that's testable, operable, and maintainable - and hold that standard across everything we ship
What We're Looking For
5+ years of hands-on production experience with AWS
Proficiency in TypeScript or Go
Strong proficiency in Infrastructure-as-Code - AWS CDK, Pulumi, or Terraform
Solid grasp of at least one other major cloud platform (Azure, GCP, Oracle OCI) or on-premise deployments
Deep expertise in serverless architectures and security best practices
Solid understanding of containerisation and Docker in real production environments
Experience with globally distributed, low-latency systems - this is core to what we do
Startup-experienced and comfortable with what that brings - fast decisions, hard problems, and real ownership from day one
Clear communicator in English - comfortable explaining complex infrastructure decisions to both technical and non-technical audiences
Nice To Have:
Experience with AI/ML workloads and GPU infrastructure
Experience in AWS CDK specifically
Background in systems programming or graphics programming
Knowledge of the Wine ecosystem (Proton, VKD3D)
