Senior Full Stack AI Engineer (NextJs/Typescript/ReactJs))

Kaishi is currently working with an early-stage AI startup building a platform that deploys specialized agents across multiple digital channels —helping businesses automate growth, content, and engagement at scale.

The product is already being used to manageworkflows across platforms like search, social, and content — replacing what traditionally requires an entire marketing team.

They're a small, fast-moving team with strong product momentum and ambitious plans ahead.

The Role

We’re hiring an early-career engineer to help build and scale a multi-agent AI platform.
You’ll work directly with the founding team across both frontend and backend — contributing to agent workflows, integrations, and user-facing features.
This is a high-learning, high-impact role with exposure to AI systems, real-world scale, and startup execution.

What You’ll Do

- Build product features across frontend (Next.js / React) and backend services

- Integrate with third-party APIs (e.g.search, social platforms, external data sources)

- Support development of agent workflows(task execution, sequencing, retries)

- Work on background job systems (queues,schedulers, async processing)

- Contribute to handling and structuring large volumes of data

- Improve system performance, reliability,and debugging processes

- Help build and enhance the user dashboard for configuring and monitoring workflows

- Collaborate closely with founders in a fast iteration cycle

What We’re Looking For

- 4+ years of experience building and shipping applications with at least 1 year working on Gen AI products

- Comfortable with TypeScript / JavaScript

- Experience with NodeJs, Typescripts and AI models

- Strong backend knowledge — APIs, databases, infrastructure

- Experience working with external APIs or integrations

- Strong problem-solving skills and attention to detail

- Comfortable operating in a fast-paced, ambiguous startup environment

Nice to Have

- Exposure to job queues, cron jobs, or event-driven systems

- Familiarity with cloud platforms (AWS, GCP, Vercel, etc.)

- Interest in or exposure to AI / LLM-based applications

- Prior experience in a startup or small, high-ownership team

Why Join

- Early engineer in a high-growth AI startup

- Work on real-world problems involving automation, agents, and data

- High ownership — your work directly impacts product direction

- Steep learning curve across full-stack and systems design
