About us
Rentman is a B2B SaaS scaleup building smart, powerful resource management software for event and production teams. Our users plan everything from small shoots to massive festivals in 70+ countries — and they all rely on Rentman to keep their gear, people, and timing perfectly in sync. Our team includes 100+ people from 30+ nationalities. We work in English, and our culture is open, inclusive, and flat — built on curiosity, ownership, and the freedom to challenge ideas.

Mission of this role

For this role, your mission is to design and build the internal systems that keep Rentman running smoothly as we scale. From customer and financial tooling to data-driven applications, you’ll empower teams across the business to work smarter, automate repetitive tasks, and make better decisions based on accurate, accessible data. You’ll play a key role in shaping a new Data team—bringing ideas, driving technical decisions, and delivering tools that make a real impact on how Rentman operates every day. You will be the first ever developer in this team!

What you’ll do

• Design, build, and maintain internal tools and systems critical to Rentman’s operations (customer management, invoicing, data sync, data warehouse)
• Make build-or-buy decisions and oversee implementation of new internal tools
• Collaborate across teams—engineering, customer success, finance—to deliver scalable, effective solutions
• Build clean, maintainable frontend and backend code (PHP, Python, SQL)
• Design integrations between systems to reduce manual work and improve data accuracy
• Stay curious—explore how emerging AI tools can optimize internal workflows

Stack

Rentman is a modern cloud-based web application, relied on daily by users to manage equipment and access data on the go. While you’ll be working primarily on our internal tooling, we expect the stack to align closely with our main SaaS platform: modern PHP, Python, MySQL, and some Angular/TypeScript for frontend work. But, this is a new team so you’ll have influence over tooling and tech choices, though we already have GCP, Mage, Bigquery & DBT for Data Architecture! This is an exciting opportunity to help establish processes and systems from the ground up. If you’re passionate about making a difference, taking ownership, and collaborating with a curious, goal-oriented team, you might be our perfect fit.

Methodology
For your role, in the brand new Data team, that structure is still being shaped - which means you’ll help design how we work. Our dev teams follow Scrum with two-week sprints and weekly releases. For you, you’ll be collaborating directly with Simon (CTO), Onno (Head of Development), and Arthur (Data Engineer) and our new Data Analyst to build a methodology that works for the new team.
