Senior Software Engineer

About Nex Gen Cloud

We are a fast‑growing company building next‑generation GPU cloud infrastructure. Nex Gen Cloud is the company behind Hyperstack, a cloud platform providing on‑demand and private cloud infrastructure for high‑performance workloads. Hyperstack is used by teams running compute‑heavy applications that need speed, reliability, and control.

AI Studio is Hyperstack’s fastest‑growing product and an end‑to‑end GenAI platform that enables customers to fine‑tune models, evaluate performance, and deploy production inference without managing infrastructure. As adoption grows and workloads scale, we are looking for a Senior Software Engineer to help shape and evolve the core systems that power the platform. In this role, you will take ownership of critical product areas and underlying services across the AI Studio stack, design and build robust user‑facing features, APIs, and backend systems that orchestrate model training, evaluation, and deployment  will play a key role in shaping technical direction, making architectural decisions, improving system reliability and performance, and raising the quality bar across the codebase.

This is a senior individual‑contributor role for an experienced Software Engineer with a high degree of autonomy and ownership. You will lead the technical design and delivery of complex systems and product areas, from early exploration through production and long‑term maintenance.

Own the design, implementation, and evolution of complex product areas and backend systems. Lead technical design for new features and services, making architectural decisions that balance scalability, reliability, performance, and long‑term maintainability from early design through production and ongoing operation.

Build and maintain user‑facing interfaces and backend services/APIs as required by the product, ensuring cohesive end‑to‑end functionality and a strong user experience.

Write clean, maintainable, and well‑tested code. Lead by example in code reviews, uphold and evolve shared engineering standards, and drive improvements to the quality, structure, and maintainability of the codebase over time.

Produce and maintain clear technical documentation for systems, APIs, and features. Help keep internal knowledge bases and relevant user‑facing documentation accurate and up to date.

Partner closely with Product and Design to shape solutions from ambiguous requirements. Work with engineers across the wider Engineering group to align on architecture, shared systems, and technical standards, and to manage cross‑team dependencies. Communicate technical trade‑offs, risks, and constraints clearly.

Take responsibility for production readiness and operational health. Identify failure modes, improve observability, and drive performance and reliability improvements.

Support and mentor other engineers through collaboration, design discussions, and code reviews, helping raise the overall quality and effectiveness of the team.

Identify high‑impact improvements to architecture, tooling, and processes, and drive initiatives that improve system quality and developer productivity over time.

• Strong experience designing, building, and operating production backend systems and APIs, with proficiency in Python and frameworks such as Flask.
• Proven ability to own complex asynchronous, long‑running, or resource‑intensive workflows end to end, with a focus on reliability, observability, and operational readiness.
• Experience shipping full‑stack product features using modern web frameworks such as Next.js, with a solid understanding of frontend and backend integration.
• Practical understanding of AI Studio style workflows in production, such as model training or fine‑tuning orchestration, evaluation, deployment, and inference. You do not need to be an ML researcher, but you should understand how models move through real systems.
• Strong system design and…
