About SINGU

At SINGU, we’re redefining how the world’s most ambitious real estate companies run their operations. Our mission is to become Europe’s leading platform for managing warehouse, logistics, retail, and multi-site commercial real estate portfolios — empowering our Clients to protect revenue, boost efficiency, and unlock new value across every aspect of their business.

 

Our unified CAFM platform already powers the daily operations of over 250 million m² of real estate worldwide, supporting more than 500,000 professionals. Following our union with the UK’s Micad and Germany’s net-haus, we now help manage 100,000+ buildings across 35+ countries — and we’re just getting started.

 

Backed by a leading growth equity investor, we’re scaling rapidly and partnering with global leaders such as Prologis, ECE, CTP, Hillwood, Logicor, GLP, and Unibail-Rodamco-Westfield. As we continue to grow through strategic acquisitions and bold innovation, we stay true to our core values: adaptability, collaboration, and client focus.

 

If you’re ready to help build Europe’s leading platform for property operations — and make a tangible impact on how the real estate industry works — join SINGU and be part of this transformation.

About the Role
We're seeking a Senior Full Stack Developer to join our product team and take ownership of everything from backend architecture to customer-facing interfaces. You'll collaborate with the Team Lead, Product Manager, and Product Designer to build reliable, secure, high-quality software.

 

As a senior engineer, you'll lead code reviews, uphold strong testing practices, mentor junior engineers, and effectively use AI-assisted development tools like Cursor or Claude Code.

What You'll Do

Backend Development

  • Build and evolve backend applications in .NET 10 and C# 14

  • Design REST APIs that are consistent, secure, and well-documented

  • Design PostgreSQL database structures, and optimize queries, indexes, and overall performance

Frontend Development

  • Build user interfaces in Angular and TypeScript

  • Take an active role in our frontend rewrite using Angular

  • Ensure UI implementations are performant, maintainable, and true to the product design

Quality & Testing

  • Treat unit and integration testing as a core part of development, not an afterthought

  • Lead and participate in code reviews with clear, constructive feedback

  • Write clean, secure, maintainable code aligned with our standards

AI-Assisted Development

  • Use AI tools (Cursor, Claude Code, or similar) to accelerate development, code analysis, and refactoring

  • Critically evaluate the correctness, quality, security, and performance of AI-generated code before it ships

Delivery & Collaboration

  • Work within GitHub and CI/CD to deliver features reliably and on time

  • Collaborate closely with your Team Lead, Product Manager, and Product Designer, and actively participate in Agile ceremonies

  • Share knowledge and mentor less experienced engineers

What We're Looking For

  • Strong hands-on experience with .NET and C#

  • Solid experience building interfaces in Angular and TypeScript

  • Experience designing REST APIs and working with PostgreSQL

  • A genuine testing habit — unit and integration tests as standard practice

  • Comfort leading code reviews and giving direct, useful feedback

  • Practical experience with AI-assisted development tools, and the judgment to critically assess what they produce

  • Excellent command of English and strong collaboration skills within a cross-functional team

Why This Role Matters

This isn't just about shipping features — it's about raising the technical bar for the whole team. You'll have real influence over technical decisions, architecture, and process, working alongside a Team Lead, Product Manager, Product Designer, and the wider Engineering and Platform teams.

If this role sounds like a good fit, we’d love to hear from you. Apply and help us build technology that supports critical operations every day.

Skills Required

  • Hands-on experience with .NET 10 and C# 14
  • Solid experience building interfaces with Angular and TypeScript
  • Experience designing REST APIs
  • Experience working with PostgreSQL, including query and index optimization
  • Strong unit and integration testing practices
  • Comfort leading code reviews and providing constructive feedback
  • Practical experience using AI-assisted development tools (e.g., Cursor, Claude Code)
  • Experience using GitHub and CI/CD workflows
  • Excellent command of English and strong cross-functional collaboration skills
