Full-stack Developer - Flux

Flux is a technology-driven company based in Amsterdam (IJburg). We build SaaS solutions for the commercial real estate sector. Our platform supports real estate valuers in their daily work — streamlining valuation workflows, improving data exchange, and connecting valuers with banks and tax authorities.

We are looking for an experienced developer with strong frontend knowledge who enjoys building well-crafted systems, cares about quality, and combines a strong grasp of the fundamentals behind the technologies they use with a continuous drive to explore and apply new technologies in practice.

Main tasks & responsibilities

• As a developer, you will take ownership of the full Software Development Life Cycle (SDLC) of our SaaS services — from design and development to deployment and operations.

• We are a small, international team of full-stack developers with different strengths across backend, frontend, and DevOps. We follow an agile way of working (Scrum) and collaborate pragmatically across those areas. 

• You will report directly to the CTO, reflecting our relatively flat structure and focus on ownership and results.

• Our platform consists of several standalone legacy systems that are still critical to the business today. At the same time, we actively evolve this landscape by incrementally migrating towards a new architecture, using well-established migration patterns rather than big-bang rewrites.

• Alongside this, we are investing in how we structure and use data across the platform — improving consistency, models, and integrations, and creating a stronger foundation for future capabilities. This also opens up opportunities to apply AI in a meaningful way, both in the product and in how we build it.
