Medior Full Stack Developer

As a Medior Full Stack Developer at dealside, you'll be a vital part of our team, working together to build the AI copilot for sales teams and to empower them to focus on what they do best - selling.

Expect to navigate a wide array of challenges that include both front-end and back-end engineering, as well as integrating Large Language Models (LLMs) into our products. Your goal will be to craft the optimal user experience while ensuring our product remains scalable.

You’ll join our ambitious dealside team as one of the first hires. This means you’ll have the opportunity to be part of an early-stage start-up and to learn from experienced serial entrepreneurs.

If you're ready to embark on an exciting journey from the early days and make a significant impact in a growing team with global ambitions, dealside is the place for you!


A non-exhaustive list of features we could use your help with:

  • Converting mockups and designs into compelling visual elements, while maintaining code integrity.
  • Building integration with LLM API’s and assisting in prompting to get the most out of our AI features.
  • Implement logging and user tracking where we can - we are hyper-focused on our users and we want to track as much as possible.
  • Adding support for new data source ingestion and assisting in maintaining clarity in our data layer.
  • Experiment with new technologies to get the most out of our stack.

We believe in shipping fast to gather feedback quickly from our customers. We focus more on building the right product than building the product right.

We like to keep things simple, so we leverage as much as possible the services offered by key vendors.

You’ll report directly to our co-founder & CTO, but you’ll work together with other departments (and customers) in detailing the requirements of features and make trade-offs together in order to maximize value while minimizing complexity.


  • We’re looking for someone with at least 2 years of experience building full stack applications. You are fluent in Typescript, familiar with React, Node.js and SQL. Experience with meta-frameworks like Remix or Next.js is a plus.
  • You’re able to slice big initiatives in small chunks so we can re-prioritize along the way in case important opportunities arise.
  • You have strong problem-solving abilities and a go-getter mentality that embraces challenges.
  • We have a data-heavy back-end, so having some affinity with data is important.
  • Personal growth is important to you, and you have the ambition to join a start-up culture.
  • Collaboration is key for us, so we’re looking for people that are fun to work with, have a lot of expertise and are open to other people’s opinions.
  • We have global ambitions so fluency in English is a must.


  • You will be able to work with super cool AI based and other state of the art tech, that will change the world of SalesTech!
  • As one of the first hires of dealside, you’ll be able to witness our growth from the first row.
  • As a part of dealside, you’ll become a part of the Ghent tech ecosystem, and a member of the StarApps ecosystem.

Next to the above very awesome perks, we offer a competitive salary with the following benefits:

  • Macbook Pro
  • Fully paid phone subscription
  • Healthcare benefits plan
  • Meal vouchers
  • Annual company retreat
  • Free office snacks
  • Team drinks and events
