Experience Required: 4+ Years

Notice Period: Immediate Joiners Only

Job Description

We are looking for a highly capable Fullstack Product Engineer to join our fast-paced team and contribute to the development and deployment of cutting-edge AI-powered products. This role is ideal for someone who thrives in high-speed environments, takes full ownership of outcomes, and is passionate about building end-to-end solutions that users love.

Must-Have Skills & Experience

Product-driven mindset: Ability to make quick tactical decisions with a strong focus on product outcomes, not just code quality.
Hands-on LangChain experience: Proven experience building real features or products using LangChain and strong familiarity with the LLM ecosystem.
AI chatbot expertise: Experience working on AI chatbots, agents, vector databases, embeddings, and prompt engineering.
AI product launch experience: Successfully launched at least one AI-powered product, ideally LLM-based.
Fullstack proficiency: Strong skills across both backend and frontend—Ruby/Ruby on Rails (or willingness to quickly adapt) and React.
Zero-API mindset: Comfortable working across the stack with minimal abstractions and without reliance on heavy API layers.
Ownership mentality: Self-starter who thrives in unstructured environments and takes accountability for end-to-end delivery.

Key Responsibilities

Lead and own end-to-end development of AI-driven products using Ruby and React, collaborating closely with product and design teams.
Rapidly prototype, build, and iterate on features with extremely fast turnarounds (days, not weeks).
Develop intelligent workflows and integrations leveraging LangChain, LLM frameworks, vector DBs, and embeddings.
Implement clean, efficient architectures without unnecessary API layers—favoring direct, smart integration.
Deliver high-impact, user-facing features that will be used by thousands globally.

Bonus Skills (Good To Have)

Experience building tools in CRM, SaaS, or automation domains.
Exposure to fast-paced startup environments.
