At Kiwi, we are already running AI in production, not just designing it, but building and shipping it across the product.
We’re looking for a Senior AI Software Engineer who is deeply hands-on and comfortable owning features end-to-end: from backend logic and AI integration to frontend experiences. This role is about building fast, iterating in production, and making AI usable for real users.
Build end-to-end features powered by LLMs and agents (backend + frontend)
Integrate AI into real user-facing flows (voice, chat, product interfaces)
Design and implement APIs and services that connect AI systems with the product
Work on performance across the stack: frontend responsiveness, backend latency, AI cost/throughput
Ship quickly, iterate in production, and continuously improve real user experiences
5+ years in software development, ideally in full-stack roles
Must have hands-on experience applying AI in live product environments, working with systems that are actively used and continuously evolving
Strong backend skills (Node.js, TypeScript, etc) and solid frontend experience (React, Next.js, etc)
Experience integrating LLM APIs, agents, or automation into real products
Ability to own features end-to-end, from idea to production
Hands-on experience with PostgreSQL or other relational databases.
Comfortable working in fast-moving environments with minimal structure
Strong execution mindset, you build, ship, and improve
Fluent English communication
Preferred: experience in fintech or digital financial products
The opportunity to build AI features used by real users from day one
Ownership of end-to-end product development, not just isolated components
Real-world challenges across backend, frontend, and AI systems
A fast-moving environment where your work quickly reaches production
Fully remote (Colombia / Argentina)
