Full Stack Software Engineer — AI,Fronted Oriented (Fully Remote)

We are looking for a Full Stack Software Engineer with strong cross-platform engineering capabilities to join our team and build next-generation AI-powered products.

The ideal candidate should have strong expertise in at least one core technology stack, while also having hands-on experience across multiple layers of the product stack, including Backend, Web, Android, and/or iOS.

Beyond traditional full-stack development, we are particularly interested in engineers who have experience with AI Agents, LLM applications, or AI-assisted product development, and who can independently take a product from technical design through implementation and production.

This is a highly cross-functional engineering role, where you will work across different technology stacks and business scenarios depending on product needs. The strongest candidates will demonstrate:

Deep expertise in one stack + hands-on experience across other stacks + strong AI/Agent capability + the ability to learn and ship independently.

For example:

• Strong Java Backend + Web + AI Agent experience → Strong fit
• Strong Web + Android/iOS + AI Agent experience → Strong fit
• Strong Android/iOS + Backend/Web + AI Agent experience → Strong fit
• Strong in only one stack with no meaningful cross-platform exposure → Lower priority
• Broad technology exposure but limited production ownership → Lower priority

Responsibilities

• Design and develop end-to-end products across Backend, Web, Android and/or iOS.
• Build scalable backend services and APIs using technologies such as Java / Spring Boot, with experience in distributed systems, microservices and high-concurrency applications.
• Develop modern web applications using technologies such as React, TypeScript, Next.js or Vue.js.
• Contribute to mobile application development on Android (Kotlin) and/or iOS (Swift).
• Design and integrate AI-powered features, AI Agents and LLM-based workflows into production applications.
• Work with LLM APIs, agent orchestration, RAG, tool calling, workflow automation and external API integrations where applicable.
• Own features end-to-end, from requirement understanding and system design to development, testing, deployment and production optimisation.
• Collaborate closely with product, engineering and business teams to translate business problems into scalable technical solutions.
• Rapidly learn and work across unfamiliar technology stacks when required.
• Contribute to engineering standards, code reviews, system reliability and overall technical quality.

Requirements

Core Engineering

• 4+ years of software engineering experience, with strong hands-on development experience.
• Strong proficiency in at least one of the following areas:
  • Backend - Java / Spring Boot / distributed systems
  • Web - React / TypeScript / Next.js / Vue.js
  • Android - Kotlin
  • iOS - Swift
  • Practical experience working across multiple technology layers is highly preferred.
  • Experience designing and developing production-grade applications, APIs or distributed systems.
  • Strong understanding of software engineering fundamentals, including system design, API design, databases, testing and debugging.
  • Ability to understand and contribute beyond one's primary technology stack.

  Cross-Platform Experience

  We are particularly interested in candidates with experience spanning 2 or more of the following:

  • Java / Spring Boot Backend
  • Web / React / TypeScript
  • Android / Kotlin
  • iOS / Swift

  Candidates do not need to be equally strong in all four areas. We value depth in one area + meaningful hands-on experience in other areas.

  AI / Agent Engineering

  • Hands-on experience with LLM applications, AI Agents, Generative AI or AI-assisted engineering is strongly preferred.
  • Experience with one or more of the following is a plus:
    • AI Agent / Multi-Agent systems
    • LLM API integration
    • RAG
    • Tool calling / function calling
    • Agent orchestration
    • AI workflow automation
    • LLM evaluation
    • AI coding / AI-assisted software development

    Engineering Mindset

    • Strong problem-solving and analytical skills.
    • Able to understand ambiguous requirements and translate them into practical technical solutions.
    • Strong learning agility and willingness to pick up new technologies quickly.
    • Good communication and collaboration skills.
    • Comfortable working in a fast-paced environment with changing business and technical requirements.
