Rentman is a B2B SaaS scaleup where we build the leading operations management platform to support event and media production teams.

Our product is our main and only focus. So if you want to work on, and improve, a long-term codebase, and think about the larger technical and product picture, then Rentman can be an interesting match for you.

All the resources behind events need to be planned up front, tracked and transported. That’s where Rentman comes into place.

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.

Build scalable, high-performance UIs with Angular and TypeScript for a real-time SaaS platform used by event professionals in 70+ countries. Lead with clean code, mentoring, and impact.

We’re based in Utrecht (NL) with a second office in Toronto (CA), and our 100+ team members work in a culture that’s open and flat, where curiosity drives us, ownership matters, and everyone has the freedom to challenge ideas and make an impact.

Our way of working

Rentman currently has 5 self-sufficient development teams, with plans to expand to 7 in the near future to realise all of our product goals.

The teams we currently have are:

  • Team equipment
  • Team project management - Responsible for our soon-to-be-released Organize product
  • Team crew - Responsible for all crew needs: planning, budgets, and time tracking
  • Team lifecycle - Responsible for everything related to onboarding and customer health

We strive to have all development teams self-sufficient and self-structured. A perfect development team consists of 2 frontend developers, 2 backend developers, a product owner, a QA engineer and a designer.

While every team is free to set their own structure and goals, currently all teams work in a traditional scrum way: 2-week sprints, with a retro to end the sprint.

Customer understanding is important at Rentman, so we facilitate visiting warehouses, interacting with customers at our “Rentman live” events, and joining various trade shows to hear first-hand from our customers how they experience our software.

Our tech stack in a nutshell

Our front-end is an Angular-based SPA with over 3,500 components. It is based on a custom-made design system, and the main data views are powered by AG-Grid. We strive to stay up to date with the latest developments, and we usually migrate to the latest Angular versions within 2 weeks of a new release.

We smartly process thousands of item records in the front-end caching layer, and actively keep client states in sync through a custom-made websocket structure.

Our back-end is a custom-made PHP framework, with a queryable API interface similar to GraphQL.

We take development at scale very seriously, and have fully typed our frontend, and even have a custom-made PHP-to-TypeScript system so that our frontend-to-backend communication is also properly typed.

What we’re looking for

  • 3 years of experience as a senior in a product-led development team or SaaS company
  • Proven experience in contributing to a user-friendly solution
  • Proven experience dealing with complex business rules and data models
  • Proven accountability for feature development solution and success
  • Positive mindset towards using AI in the development toolchain

For us, having Angular experience is a nice-to-have. At Rentman, we believe that every good developer understands that a framework is a tool to help achieve results and that you can always learn a new framework if you have strong fundamentals.

What you’ll get

  • An ambitious, diverse international team
  • Competitive salary (+8% holiday benefit) based on experience
  • A “13th month” annual bonus based on company results
  • 25 days of paid vacation, plus one extra day off each year from your 2nd year onwards up to your 5th anniversary
  • A paid 4-week sabbatical after 5 years to go on an adventure
  • Flexible WFH policy and work from anywhere for 4 weeks a year
  • A shiny Windows, Linux or Mac of your choice
  • An annual training budget to boost your skills
  • A pension plan via BrightPensioen
  • Access to OpenUp for mental well-being and personal growth
  • Sports activities (Rentman football team, squash and padel) and a Onefit fitness subscription
  • An OV Business card if you live further than 10km away from the office
  • A flexible and engaging work environment with free lunches, office perks (PS5, Ping Pong, D&D), legendary karaoke parties, and various team activities
  • An amazing office in the heart of Utrecht, Netherlands, at the historical Drift 17

Rentman is the all-in-one solution that lets event rental teams work more productively. From one-man shows to large production companies, thousands of event professionals use Rentman to realize big and small events from start to finish. Thanks to this, millions of people were able to enjoy special moments - and this is what it's all about.
