About the Role

Were looking for a Senior Full Stack AI Engineer to join a small, high-impact team working at the intersection of product engineering and AI-driven solutions.

This is not a traditional full-stack role. Its a highly autonomous, product-focused position where youll take ownership from idea to production, working across backend, frontend, architecture, and AI-enabled features. Youll operate in a fast-paced, low-process environment, translating ambiguous stakeholder needs into working solutions while balancing rapid delivery with long-term quality.

Youll work across both improving an existing Python-based application and building new AI-powered solutions, often prototyping and shipping within short timeframes. This role requires strong engineering judgment, a proactive mindset, and the ability to bring structure and best practices into an evolving environment.

• Translate ambiguous stakeholder requirements into structured solutions, user flows, and deliverables


• Design system architecture, making decisions around scalability, maintainability, and security


• Build and deliver end-to-end features across frontend and backend with full ownership


• Rapidly prototype AI-enabled solutions and evolve them into production-ready systems


• Improve and scale an existing Python-based application, addressing backlog, performance, and UX gaps


• Define and implement UX flows and usability improvements (not visual design, but user journeys)


• Integrate with APIs, including AI-driven services, and design robust data flows


• Apply secure development practices and ensure systems are reliable and maintainable


• Balance speed of delivery with long-term engineering quality and structure


• Contribute to and elevate engineering practices (architecture, SDLC, testing) through hands-on work


• Collaborate with stakeholders and team members while operating with a high degree of independence

• Strong experience with Python (5+ years) in production environments


• Proven experience in system design and architecture (5+ years), including making trade-offs


• Hands-on experience with AI-assisted development tools (e.g., Codex, Claude, or similar) in real workflows


• Strong experience integrating APIs, including AI or data-driven services (3+ years)


• Solid frontend experience with React and modern JavaScript/HTML (3+ years or equivalent frameworks)


• Experience owning features or products end-to-end, from concept to delivery (3+ years)


• Strong understanding of SDLC, engineering best practices, and code quality standards


• Experience working in ambiguous environments and shaping requirements independently


• Proven ability to prototype quickly and deliver at pace (2+ years)


• Strong stakeholder communication skills and ability to translate business needs into technical solutions (5+ years)


• Good understanding of UX flows and usability principles (2+ years)


• Experience working with databases and data modelling (3+ years)


• Understanding of secure development practices (3+ years)


• Experience handling data pipelines or ETL processes (2+ years)


• High ownership mindset with the ability to operate independently in a low-structure environment

• Experience working in small, high-autonomy teams without dedicated QA or BA support


• Exposure to building AI-powered products or LLM-based workflows in production


• Experience improving engineering maturity (architecture, testing, SDLC) within teams


• Familiarity with rapid prototyping tools and experimentation environments


• Strong product mindset with the ability to balance user needs, business goals, and technical constraints

• Fixed Shifts: 12:00 PM - 9:30 PM IST (Summer) | 1:00 PM - 10:30 PM IST (Winter)


• No Weekend Work: Real work-life balance, not just words


• Day 1 Benefits: Laptop and full medical insurance provided


• Support That Matters: Mentorship, community, and forums where ideas are shared


• True Belonging: A long-term career where your contributions are valued


• 5-Day AI Training: Hands-on AI Academy onboarding to get you building with AI from day one
