Truston Solutions BV vacatures

It’s not just a job — together, we’re on a mission. We're committed to accelerating the energy transition, with the goal of empowering 2 million sustainable energy installations by 2035. But we cannot achieve this goal alone. We are looking for talent to strengthen our team and work with others on what really matters.

The team you will join

At iChoosr, you will join a team of 160 goal getters with a proactive approach, a strong sense of ownership and strong interpersonal skills. Your colleagues work across the US, the Netherlands, Belgium, the UK, Poland and Japan.

As a Solution Architect, you will work at the intersection of technology strategy and hands‑on architectural design. You’ll combine a strong technical foundation with an enterprise perspective, helping ensure our architecture scales with our business ambitions.

Working closely with the CTO, Tech Leads, Data Architect, Product Teams, and Office Technology Team, you’ll be responsible for steering architectural direction, constructively challenging technical decisions, and ensuring coherence across our technology landscape.

Over the last two years, iChoosr has undergone a major digital transformation with a new scalable platform that enables business teams to execute group‑buying campaigns. Following the successful MVP release of this initiative, your focus will shift toward extending this new platform, decommissioning legacy components, and embedding sound architectural governance and documentation practices, including maintaining our ArchiMate architecture repository.

You will also play a key role in supporting the Office Technology Team with governance and decision‑making related to the broader technology ecosystem outside the platform, ensuring that all IT systems adhere to architectural principles and align with technology standards.
