Solos Technology Limited
Software Engineer

We are an innovative startup at the forefront of AI-driven smart glasses and mobile applications. Our products seamlessly integrate advanced multimodal large language models (LLMs), real-time image recognition, IoT, and edge computing to redefine how users interact with the world.

We're looking for talented Software Engineers who specialize in Backend systems, Mobile SDK development, AI-powered solutions, or both. You’ll help shape the future of wearable and mobile AI alongside a fast-moving team that takes ideas from prototype to production with speed and purpose.


What You’ll Do

Depending on your specialization, your responsibilities will fall into one of the following tracks:

Backend Engineer

  • Design, develop, and optimize backend services for smart glasses and mobile ecosystems.

  • Build robust APIs that integrate AI features like chat, translation, image recognition, etc.

  • Deploy and manage scalable, cloud-native infrastructure (preferably on AWS).

  • Support real-time communication use cases.

  • Focus on system performance, security, and maintainability.

AI Engineer

  • Research and develop AI features such as multimodal chat, real-time speech translation, retrieval-augmented generation (RAG), computer vision, etc.

  • Fine-tune and deploy LLMs or vision models on cloud and edge devices to support low-latency applications.

  • Stay up to date with the latest in generative AI, NLP, and CV—and bring those innovations into production.

  • Collaborate closely with backend, mobile, and hardware teams to build cohesive user experiences.

Mobile SDK Developer

  • Build native iOS/Android SDK using Swift and Kotlin.

  • Apply multithreading and concurrency programming models effectively.

  • Implement and optimize features requiring Bluetooth Low Energy (BLE) and Wi-Fi stack.

  • Build and optimize AI-powered mobile apps (Local LLM, NLP, CV, etc.) running locally with low latency and efficient resource usage.

  • Develop applications that run continuously in the background with low power consumption.

  • Collaborate with AI and backend engineers to deliver seamless end-to-end experiences on wearable and mobile platforms.


What You’ll Need

General Requirements (All Candidates)

  • Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field.

  • Self-driven, curious, and excited to work in a fast-paced startup environment.

  • Strong problem-solving skills, a can-do attitude, and a collaborative mindset.

  • Experienced engineers will be considered for senior roles.

For Backend Engineers

  • Strong programming skills in TypeScript/Node.js.

  • Experience with NoSQL databases and SQL database.

  • Experience working OpenAI API, LangChain or other LLM framework in a backend context.

  • Experience with cloud-native applications (AWS preferred).

  • Understanding of real-time systems or streaming technologies.

  • Familiarity with backend frameworks such as Express, NestJS, Fastify, etc.

For AI Engineers

  • Proficient in Python and familiar with modern ML frameworks like PyTorch, Hugging Face Transformers, or TensorFlow.

  • Strong understanding of LLMs, NLP, real-time translation, computer vision, etc.

  • Experience with LangChain, RAG pipelines, or multimodal AI tools and frameworks.

  • Experience deploying and optimizing AI models for cloud or edge inference.

  • Knowledge of model optimization techniques (e.g., quantization, pruning, distillation) and fine-tuning for low-latency applications.

For Mobile SDK Developers

  • Proficiency in Swift (iOS) and Kotlin (Android).

  • Experience with multithreaded and concurrent programming.

  • Strong knowledge of BLE and Wi-Fi stack communication.

  • Experience developing and optimizing on-device AI applications.

  • Proven track record building apps that run reliably in the background with low power consumption.


Why Join Us?

  • Shape the future of next-gen AI wearable devices.

  • Work on real products used by real users.

  • Move fast, ship often, and learn continuously.

  • Collaborate with passionate engineers and innovators
