We are seeking a founding engineer to help us build the foundations of our tech stack and team. This person should be excited about joining an entrepreneurial journey and significantly impacting the product and technical stack. We’re looking for someone who’s independent and eager to navigate uncharted waters.

This is a unique opportunity to join WhatsAppX as one of the first engineers and significantly impact the product and technical stack.

Previous experience in a startup or scale-up organisation is highly valued.

🎯 Your mission

You will work closely with Thomas (CTO) and Paul (CEO) to build a world-class product from scratch.

Responsibilities

• Build the foundations of the platform

• Build, maintain and test product features end-to-end, from the user interface to the API, from the documentation to the security aspects

• Work closely with the founders and product team of eFounders to shape the platform

• Implementing coding best practices (clean code, test, typing…), help us build a very high-quality codebase and set the foundations of what it will become

• 4+ years of experience in a full-stack web dev position, or a backend dev position (ready to jump-in on frontend tasks)

• Strong experience in Node.js (vanilla or one of its backend variants: Express, NestJs, …). Cherry on the cake: experience in NestJs

• Experience with relational database

• Ownership mentality: you like to take initiative and build features from conception to production

• Product & business sense: you care about what you build and the value you create for users. “code is just a way to a bigger mean” → this sentence resonates with you

• Team player: you enjoy learning from each other, thrive in teams and communicate with ease

• Bias for action: you are a doer and like to build, no task is below you

• Strong attention to detail: code quality and good UX is important to you and you set a high bar

💻 Our tech stack

This is the stack that we work with, you don’t have to know it all:

• Tools: Github, Github actions, Postman, Copilote etc…

• Frontend: React, TailwindCss, TailwindUI

• Backend: NestJs monolith for the API, outposts with serverless Lambdas

• DB: Postgres & TypeORM (ORM)

• Testing: Cypress, Jest

• Infra: AWS, Serverless Lambda, CDK

Engineering mindset

• We want to go fast. Velocity is our greatest weapon

• We strive for software craftsmanship and good practices, such as clean code, peer programming, and code reviews

• Develop, deploy and maintain features. We own our choices and our code!

• The tech serves the company’s goal, not the other way around

• Each piece of code serves a specific purpose and delivers value

• We are here to ship, build a startup and to have fun while doing 🚀

Benefits

• Competitive compensation and equity package

• Latest Macbook Pro + Monitor

• Awesome colleagues with high ambitions (the founders + Hexa (eFounders) core team)
