Job Description

As a

Full-Stack Engineer

, you will take a leading role in building and evolving an AI-powered platform for

our client, an ambitious startup based in Antwerp

. You’ll own features end-to-end — from early concept and specification through development and deployment. AI is at the core of the product, meaning you’ll be building applications where machine learning is deeply embedded rather than treated as an add-on.

A key part of this role is direct collaboration with customers. In the absence of traditional product managers, you’ll work closely with users to understand their challenges and translate real-world needs into robust technical solutions. This customer-facing responsibility is essential to ensure the product delivers genuine value.

Beyond hands-on engineering, you’ll contribute to product discussions, technical decision-making, and brainstorming sessions. This is a chance to shape both the product and the engineering approach, with real influence on technical direction and company strategy.

What We’re Looking For

Strong experience with

React and TypeScript

(experience with Remix and React Router v7 is a plus)

Ability to

lead projects independently

from idea to production

Excellent written and verbal

communication skills in English

, with strong attention to detail

Deep understanding of

TypeScript fundamentals

and experience building scalable full-stack applications

Experience building

AI-driven applications

(prompt engineering and/or fine-tuning experience is a plus)

A collaborative and proactive mindset, comfortable working autonomously in a

small, fast-paced startup environment

Why Join?

Work alongside a

highly experienced, senior-level technical team

Build with

cutting-edge AI models

at the forefront of innovation

Join a

hyper-growth, VC-backed startup

where speed, ownership, and impact truly matter

Be part of a team that values

excellence, execution, and technical quality

Competitive salary, performance-based incentives, and significant

personal and professional growth opportunities
