Full Stack Engineer

The Role

We're looking for a sharp, versatile Full-Stack Engineer who can move fluidly between intelligent backend systems and polished mobile experiences. You'll work at the intersection of AI, mobile, and platform engineering.

What You'll Do

• Design and build mobile features using JavaScript across iOS and Android
• Develop and maintain Python-based backend services, APIs, and AI/ML pipelines
• Implement and optimize machine learning models for recommendation, search, fraud detection, and personalization
• Architect scalable, algorithm-efficient systems that perform under real-world load in emerging market conditions (low bandwidth, diverse devices)
• Collaborate with product, design, and data teams to ship end-to-end features from idea to production
• Contribute to our Miniapp SDK and developer platform used by third-party businesses deploying on Ramses

What We're Looking For

• 1+ years of experience in full-stack or mobile software engineering
• Strong proficiency in JavaScript/TypeScript for cross-platform mobile development
• Solid Python skills for backend development and ML/data workflows
• Hands-on experience building and working with AI agents — designing agentic workflows, tool-calling systems, and multi-step autonomous pipelines in production environments
• Proficiency working with LLMs — prompt engineering, fine-tuning, API integration, context management, and embedding LLM capabilities into real user-facing features
• Practical experience with agentic coding tools and frameworks (such as LangChain, LangGraph, CrewAI, AutoGen, or similar) to build systems where AI takes meaningful, chained actions
• A solid foundation in algorithms and data structures — you think about complexity, not just correctness
• Experience with REST APIs, cloud infrastructure (AWS, GCP, Azure, Digital Ocean), and SQL/NoSQL databases
• Ability to work independently and take ownership of features from spec to deployment

Bonus Points

• Introvert personality
• Superhuman focus
• Hardcore engineer
