Job description

We are seeking a Mid–Senior Full-Stack Software Engineer to help build and scale the HyperDev platform. You will work across both frontend and backend systems, building production features, integrating APIs, and contributing to a high-quality developer experience.

You’ll collaborate closely with product and engineering teams to deliver reliable, scalable solutions while contributing to technical decisions and continuous improvement of our platform. This role is ideal for a hands‑on engineer who enjoys solving practical problems, shipping features, and working across the full stack in a fast‑moving environment.

Responsibilities

• Build and maintain full‑stack features across frontend and backend systems.
• Develop and maintain APIs and backend services.
• Implement responsive, high-quality frontend experiences.
• Integrate third‑party services and APIs.
• Collaborate with product and design teams to ship features.
• Write clean, tested, maintainable code.
• Contribute to system performance, reliability, and scalability.
• Support CI/CD, testing, and engineering best practices.
• Work with AI‑powered tooling where relevant to improve developer workflows.

About Us

At HyperDev, we don’t believe AI replaces developers. We believe it should make them faster, clearer, and more human.

Our platform turns natural language into real, working software while keeping people firmly in the loop. AI generates structure and logic; humans guide intent, judgement, and quality. The result is code that stays understandable, controllable, and owned by the people building it—not a black box you’re afraid to touch.

HyperDev is a spin‑out within the HyperionDev ecosystem, backed by a profitable global tech education company. Our founding team includes engineers who have worked on generative AI models at OpenAI and technical leaders behind award‑winning software products. We’re building tools for developers who want leverage, not autopilot.

If you care about craft as much as speed, and you want to shape how humans and AI build software together, you’ll feel at home here.

Minimum:

• 4+ years of commercial full‑stack development experience
• Strong frontend experience (React + TypeScript)
• Strong backend experience (Python — Django/FastAPI or similar)
• Experience building and consuming REST APIs
• Experience with Git and modern development workflows
• Experience integrating third‑party services/APIs
• Experience writing automated tests
• Experience working in production environments
• Ability to work independently in a fast‑moving team

Preferred:

• Experience working with LLM APIs or AI tools
• Exposure to AI coding tools (Copilot, Claude, Cursor, etc.)
• Experience with cloud deployment or containerisation
• Modern CSS frameworks (Tailwind, etc.)
• DevOps exposure
• Interest in developer tooling or AI platforms

Why Join Us?

• Be part of the founding team of a new AI developer platform backed by an established, profitable parent company.
• Shape the architecture, product, and culture of a company from day zero.
• Collaborate with a team that has worked at OpenAI and shipped award‑winning products.
• Access the resources, backing, and reach of the HyperionDev ecosystem while building something new.
• Work on the cutting edge of AI and developer tooling, with the freedom to experiment and innovate.
