WHY JOIN US

If you're looking for a place to grow, make an impact, and work with people who care, we'd love to meet you!

ABOUT THE ROLE

We are looking for a Senior/Lead AI Software Engineer (Full Stack) to build and scale intelligent, AI-driven products from concept to production in rapid iteration cycles. This role is pivotal in architecting end-to-end AI solutions—leveraging LLMs, RAG pipelines, vector databases, and Rust or Golang—to power high-performance, low-latency applications. You’ll shape scalable AI architectures, automate workflows, and drive innovation in a fast-growing environment that values ownership, speed, and technical excellence.

WHAT YOU WILL DO

• Architect and develop robust, scalable AI-powered features across frontend and backend;
• Design and implement end-to-end AI solutions, from data ingestion to model integration and user-facing interfaces;
• Rapidly gather business and technical requirements and translate them into functional AI demos within 1–2 weeks;
• Integrate LLMs and AI services (e.g., APIs, vector databases, RAG pipelines) into production-ready applications;
• Work deeply in the existing web app codebase, enhancing core modules and integrating AI capabilities;
• Architect high-throughput, low-latency systems that scale reliably;
• Collaborate closely with Product, Design, and Engineering;
• Maintain high standards for documentation, testing, observability, and code quality;
• Lead technical initiatives to automate manual workflows using AI and improve system reliability.

MUST HAVES

• 5+ years of full-stack development experience
• Experience in Rust or Golang
• 2+ years of AI/ML engineering experience building or integrating AI-driven systems
• AI-assisted code experience with tools such as GH Copilot, Cursor, or Windsurf
• Proven ability to gather ambiguous requirements and independently develop AI prototypes/demos within short timelines (1–2 weeks)
• Strong experience working with LLM APIs, prompt engineering, embeddings, and vector databases
• Experience designing scalable AI architectures (RAG, agents, model orchestration, evaluation pipelines)
• Proven ability to navigate and improve large, production-scale codebases
• Strong understanding of performance optimization, system design, and low-latency architectures
• Excellent communication and documentation skills in a fast-moving team environment
• Demonstrated experience deploying AI features into production environments
• Upper-intermediate English level

NICE TO HAVES

• 2+ years of team lead/management experience
• Strong skills in Python
• Experience with CI/CD pipelines
• Experience with cloud platforms and AI tools such as Vertex on GCP, SageMaker, Bedrock from AWS, and similar ones
• Experience with AI frameworks/SDKs (LangChain, LlamaIndex, Hugging Face, etc.)
• Experience building AI agents or multi-agent systems
• Start-up mindset: comfortable experimenting, iterating quickly, and tackling ambiguous challenges

PERKS AND BENEFITS

• Professional growth: Mentorship, TechTalks, and personalized growth roadmaps.
• Competitive compensation: USD-based pay with education, fitness, and team activity budgets.
• Exciting projects: Modern solutions with Fortune 500 and top product companies.
• Flextime: Flexible schedule with remote and office options.
