ABOUT QUANTUMLOOPAI

Backed by leading investors and scaling rapidly ahead of our Series A, we are building the infrastructure that will define the next generation of AI-driven service delivery.

ABOUT THE ROLE

We are looking for a Full Stack Engineer (Backend Heavy) to join our growing India-based development team. You will work across the full stack but spend the majority of your time designing, building and scaling the backend services and APIs that power EMMA. This is a hands-on engineering role where you will take ownership of core platform infrastructure, collaborate with our UK-based product and engineering teams, and help us scale a system that is growing fast.

WHAT YOU WILL DO

  • Architect, develop and optimise scalable, secure backend services using Node.js, TypeScript, and NestJS within a distributed microservices architecture.
  • Build responsive, intuitive user interfaces using React, Next.js and TypeScript to complement backend capabilities.
  • Design, optimise and maintain MySQL databases for high-performance, high-availability applications.
  • Contribute to CI/CD pipelines and automate build, test and deployment processes using Azure DevOps and Docker.
  • Write high-quality, maintainable code and conduct thorough code reviews to uphold engineering standards across the team.
  • Collaborate with Product Owners, Business Analysts, UX Designers and fellow engineers to understand requirements and deliver robust end-to-end solutions.
  • Mentor team members on backend and frontend development best practices, with a focus on building scalable and efficient systems.
  • Advocate for best practices in software development, DevOps and agile methodologies to ensure a secure, reliable and performant platform.

Requirements

ESSENTIAL

  • Minimum 2-3 years of experience building scalable, distributed backend systems using Node.js and TypeScript.
  • Proficiency in developing user interfaces using React, Next.js and modern frontend frameworks.
  • Strong understanding of distributed systems, microservice architecture and API design.
  • Expertise in creating secure, scalable RESTful APIs and/or GraphQL endpoints.
  • Experience building responsive UIs using React, Next.js, Redux and TypeScript, with solid understanding of component-based architecture and state management.
  • Proficiency in designing and optimising MySQL databases for high-performance applications.
  • Hands-on experience with Azure or similar cloud platforms for hosting, scaling and monitoring applications.
  • Familiarity with CI/CD pipelines using tools like Azure DevOps and containerisation with Docker.
  • Deep understanding of secure coding practices, authentication mechanisms and API gateways.
  • Strong analytical skills with the ability to break down complex problems into atomic units of work.
  • Excellent written and verbal communication skills, comfortable collaborating asynchronously with a UK-based team.
  • Comfortable working remotely and aligning to UK business hours (9:00 AM to 6:00 PM GMT/BST).

DESIRABLE

  • Experience working on high-traffic platforms or products serving large user bases at scale.
  • Experience with Ionic or similar hybrid mobile application development frameworks.
  • Advanced Azure capabilities such as Kubernetes, CosmosDB and API Management.
  • Familiarity with Firebase for notifications and real-time features.
  • Proven ability to mentor junior team members and lead by example.
  • Experience with NestJS or similar backend frameworks.

LOGISTICS

  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
