About Nexgen Cloud
NexGen Cloud is the company behind Hyperstack, a full-stack AI cloud serving tens of thousands of customers from AI researchers to enterprises running the world's most compute-intensive workloads. We deliver on-demand and private GPU infrastructure to teams who treat performance as a requirement, not a feature.
We're a tight-knit, fast-moving team working at the cutting edge of AI cloud infrastructure. We practice what we preach, equipping our people with AI at every level so we can solve harder problems, ship faster, and keep raising the bar for what enterprise GPU infrastructure looks like.
The Role: Senior Software Engineer – AI Studio
This role exists because AI Studio — Hyperstack's platform for fine-tuning, evaluating, and deploying generative AI workloads — is growing fast and needs engineers who can take real ownership of the systems behind it. You'll design and build the core backend services, APIs, and user-facing features that orchestrate model training, evaluation, and deployment at scale, and contribute to architectural decisions that shape how the platform evolves.
This is a role for someone who takes accountability for production systems, thinks carefully about architecture, and wants to see the direct impact of their work on a platform used by thousands of AI teams.
What You'll Be Doing
- Design, build, and evolve core backend services and platform components — making architectural decisions that support scalability, reliability, and long-term maintainability
- Develop and maintain both backend services and user-facing interfaces that support AI workflows including model training, evaluation, and deployment
- Improve system observability, diagnose production issues, and optimise performance to keep the platform running
