  • Enjoy switching hats — builder, debugger, architect, and product thinker when needed
  • Believe clarity comes from action — prototype, test, and iterate without waiting for perfect plans
  • Stay calm and effective in startup chaos — shifting priorities and building from zero doesn't faze you

Job Description

Founding Full Stack AI Engineer - NodeJS - AI Start-up k plus equity

Agentic Realm

So joining a start-up there are always risks, do the founders have pedigree in previous ventures? Is there a proven MVP and financial security?

The main thing to notice that the
founders have had a successful exit previously, they are excellent at fundraising and finding their niche on the market.

This is an AI start-up, so the stack is as modern and fresh as they come. Their platform is all TypeScript based and of course the AI/ML stuff is Python based.

So I would love to chat with you if you have the following criteria
:

  1. You like in-person collaboration.(They built their last company on in working in the office)
  2. You have been through the start-up trenches of an early stage SaaS start-up.
  3. Have been involved in an early stage start up before and been through the entire product lifecycle.
  4. You thrive in a fast paced environment where use cases and requirements can change fast.
  5. You are agnostic to the tool and framework to get the work done.
  6. You are a self starter.
  7. Generally be sound and a nice person.

Technically speaking you will have experience with as many of these:

Python

Very strong grasp of complex SQL queries

Have a love for classic machine learning things such as neural networks.

Having a strong knack for maths and know what is going on under the hood with the algo logic.

Coordinating intricate LLM workflows.

Would be excellent if you also had:

TypeScript - (Nest/Next)

tRPC

Data Pipelining experience

LLM tools like HuggingFace, Langchain, OpenAI etc.

This role will not be for everyone, firstly, it is not full remote, as they are an early stage start-up they want to brainstorm in-person. They also need someone with extremely strong opinions, they want an engineer not just an implementer. They want you to question to status-quo. You will be someone whose passion is your engineering, so in your job and in your spare time.
