MERN Stack Developer

About Us

We believe the future of software development is AI-native — where engineers operate at a higher level of abstraction and quality remains non-negotiable. 

Incubyte is a software craft consultancy where the “how” of building software matters as much as the “what”.  

We partner with companies of all sizes, from helping enterprises build, scale, and modernize to early-stage founders bring their ideas to life. 

Our engineers operate in an AI-native development model, using AI as a collaborator across the SDLC to accelerate development while upholding the discipline of software craftsmanship. Guided by Software Craftsmanship and Extreme Programming practices, we build reliable, maintainable, and scalable systems with speed, without compromising quality. If this way of building software resonates with you, we’d like to talk.

You should be able to build and support complex applications single-handedly with a keen eye towards UX, design, security and performance. Additionally you will need to have a basic understanding of microservices, API integrations to aid in achieving our vision of building the most robust and scalable integration platform in the B2B Retail + Food verticals.

Our stack is primarily built around Node, PHP, React, Angular, Mongo, PHP and advanced Infra and DevOps tools such as Kubernetes, Grafana, Prometheus, ELK and more.

Mentoring should come naturally to you, as well as finding the right balance towards process and documentation.

Highlights:
1) You will be working on interesting technical challenges in a product centric and open-source driven environment.
2) You will help set a very high bar on code quality with a focus on test driven development and writing highly performant, fault tolerant and secure code.
3) You will take ownership of product features from conception to implementation, testing deployment and support.
4) A lot of freedom on when and where you work from - just get stuff done.
5) You will open source as much as possible, and blog about cool things that you learnt and built.

7) You will get stock options in line with silicon valley standards.


Caveats:
1) We have a strict no-divas rule. There are a lot of smart engineers on the team but no one with an attitude / superiority complex.
2) If you think writing tests for your code, writing docs, doing customer support etc are not your cup of tea, this isn't the right role for you.
3) Similarly, if you're viewing this just as a 20-40% increment opportunity over your current compensation, this isn't the right role or company for you.
