Job description

Medior Software Engineer (Go, PHP) – EV Charging Location Data Platform

Location: Utrecht, Netherlands (Hybrid, 3 days/week in office)

Base Pay Range: €60,000 – €75,000 + holiday allowance, plus a lot of great benefits (see below)

(Scale-up, 60+ people, Utrecht, Netherlands, mission-driven)

Our client is a leading independent global platform for EV charge point location and pricing data. They give navigation providers, charge point operators, eMSPs, and the public sector accurate, trustworthy data on where EV charging happens and what it costs. With over 1.5 million connectors tracked across 80+ countries, they support the electrification of both passenger and heavy-duty vehicles. They\'re looking for people who want their work to have a direct, measurable impact on the transition to electric mobility.

The Role

As a Medior Software Engineer, you\'ll design, build, and harden one of the company\'s most foundational products: validated, enriched location data for charging stations worldwide, delivered via an OCPI-based API. You\'ll report to the Team Lead of the Locations team and contribute to the architecture, data integrity, and security of the systems you work on.

You\'ll help drive the migration of foundational backend services from PHP to Go, modernizing systems that power data for 1.5M+ EV connectors globally while maintaining performance and security throughout. You\'ll also help modernize internal tooling for data validation workflows, treating maintainability and readability as core priorities.

You\'ll work across the API, data, and security layers, collaborating with the product manager and wider team to help shape the technical roadmap. The stack is Go and PHP (Laravel), used intermittently, running on Google Cloud Platform, MySQL, Postgres, Kubernetes, and Docker, with the team actively transitioning from PHP to Go. AI tools (e.g. Claude Code, Gemini) are available and encouraged, with a strong expectation that engineers personally own what they ship.

Key Responsibilities

• Contribute to critical backend components as part of the PHP to Go migration
• Help ensure the integrity, performance, and security of data powering 1.5M+ EV connectors worldwide
• Modernize internal tools supporting data validation workflows
• Write clean, maintainable code and take full ownership of your deliverables
• Proactively identify and propose improvements to architecture, performance, scalability, and security
• Work with the product manager and team to support the technical roadmap
• Collaborate cross-functionally to ensure API and data reliability for clients

Requirements

• 2 to 4 years of professional software engineering experience, including hands-on Go or PHP (Laravel)
• Solid technical proficiency with Google Cloud Platform, MySQL, Postgres, Kubernetes, and Docker
• Experience with automated testing and a genuine focus on code maintainability
• Nice to have: PHP experience (the team is transitioning away from it)
• Nice to have: familiarity with GitLab CI
• Comfort with system design fundamentals
• Strong communication and collaboration skills, with a growth mindset

We Care

• Salary: €60K–€75K plus holiday allowance
• Visa sponsorship available for candidates already located in the Netherlands (relocation is not offered)
• Fun, international team with frequent company events
• Dynamic scale-up environment: real opportunity to make an impact
• Own office right next to Utrecht Central Station
• Hybrid working: 3 days in office, 2 from home. Monday and Thursday are mandatory office days, with free healthy lunch provided
• 20 weeks of 100% paid parental leave
• €150 medical allowance
• Employee well-being support and fitness programs
• Membership to MyWheels, an EV car-sharing service
• 1-year contract
• Freedom and autonomy: no dull moments guaranteed
