Job description

Are you an experienced full‑stack developer who enjoys working with React.js, Next.js, and PHP? Do you embrace AI‑assisted development to build better code faster? And are you looking for a versatile senior role where you can help shape and scale a state‑of‑the‑art marketplace?

Have you ever searched for a painter or accountant online? It can be quite a task. That’s why we started Trustoo in 2019. Trustoo is the online marketplace for local entrepreneurs, where visitors can easily find the best companies. Think of Booking.com or Tripadvisor, but for local services. Today, Trustoo offers a digital platform to over 300,000 local companies in the Netherlands, Germany, Belgium & Spain. Our team of 80+ enthusiastic and driven colleagues ensures you’ll enjoy going to work every day, while together developing and scaling the Trustoo platform.

Why your role is crucial for Trustoo

Pieter (co‑founder): “With our unique and transparent concept, we’ve seen unstoppable growth in recent years in the Netherlands. The main driver behind this growth is our platform development team, who build a state‑of‑the‑art marketplace and improve it every day.”

Position

As a Senior Full‑Stack Developer at Trustoo, you’ll work on many aspects of the platform. We continuously add new functionality to our apps and infrastructure. As we grow and scale, we want to keep improving and adopt the latest technology, so you will work for a team that drives innovation. We’re looking for someone who brings not only technical skill but also initiative and ownership. Someone who thrives on running projects end‑to‑end, perhaps has built side projects, or even helped launch/start a company. Having a publicly available portfolio or proven track record that we can look at is a strong plus.

We practice Agile methodology and embrace modern development practices, including AI‑assisted coding. At the heart of our success is close cooperation between developers, product managers, and marketers (UX/UI, Content, SEO & SEA). That’s why we do everything in‑house with a dedicated team. This enables us to innovate quickly and learn what really works.

Our Tech Stack

Front‑end: React.js and Next.js for web applications
Back‑end: CakePHP framework
AI: Python, Claude, OpenAI, Gemini
Version Control: GitHub
Cloud Infrastructure: AWS
Development Tools: JetBrains, AI‑first IDEs (e.g., Cursor), and LLMs
Best Practices: Code reviews, automated testing, CI/CD pipelines, clean code principles.

In short, you will:
- Build and improve AI tooling for our SMB customers
- Build and improve new products and product features
- Build and improve React/Next.js front‑end applications (including A/B testing), APIs, dashboards, search, and data flows
- Develop and maintain React/Next.js front‑end applications and back‑end services in CakePHP
- Use AI‑first IDEs and LLMs to write better code faster
- Deploy to AWS and collaborate via GitHub
- Take ownership of projects, from concept to implementation
- Work closely with colleagues across development, product, and marketing to innovate and scale.

What does your day look like?

You’ll start with the daily stand‑up with your platform team colleagues. You set your own priorities within the sprint goals: planning, developing, testing, and shipping. With our open culture, direct access to founders, and relatively small company size, decisions are made quickly. Every week we close together with all colleagues: reviewing progress, celebrating milestones, and sharing results.

We are looking for someone who

Has an academic level of work and thinking
Has 4+ years of experience as a full‑stack developer (senior level)
Has strong knowledge of Python
Has knowledge of JavaScript, React.js, and PHP
Has experience in building AI Agents and RAG pipelines
Has experience with or interest in Next.js, CakePHP, GitHub, and AWS
Actively uses AI‑first IDEs and LLMs to boost productivity
Is capable of running projects independently, taking initiative, and delivering results
Is eager to join an ambitious journey to build the leading services marketplace in Europe.
