As part of our SaaS Business Unit, you will directly contribute to the product and technical OKRs that drive our growth and scale.

The Role

We are seeking a Backend Engineer with 3–6 years of relevant experience and a strong PHP background to accelerate the development of our core SaaS platform. This role sits within a multidisciplinary tech unit that spans Backend, Data, Product, and Design—and interfaces directly with our real estate industry users.

This position is intentionally designed as a growth role, offering clear ownership areas, mentorship, and a pathway toward becoming a Senior Backend Engineer.

Your Responsibilities
  • Build and evolve backend services and APIs powering B2B SaaS workflows

  • Work on long-lived, production systems with real customers and business dependencies

  • Advocate for maintainability, scalability, and pragmatic engineering

  • Contribute to structured technical decision-making and architectural discussions

Your Skills and Qualifications
  • 3+ years of experience as a Backend Engineer or comparable role, with a strong focus on PHP

  • Strong understanding of backend architecture, API design, and relational databases

  • Experience building and maintaining digital products used by real customers

  • Ability to write clean, testable, maintainable code and improve legacy code when needed

Experience that will set you apart:

  • Background in real estate, PropTech, ClimateTech, or related digital products

  • Experience with B2B SaaS platforms

  • Familiarity with multi-tenant application architectures

  • Exposure to modern PHP frameworks, domain-driven design, or service-oriented architectures

Mindsets we value highly:

  • Customer-obsessed approach with strong stakeholder empathy

  • Ownership mentality with hands-on execution and “get-things-done” mindset

  • Comfort with ambiguity in fast-evolving environments

  • Structured problem-solving and analytical thinking

  • High degree of self-initiative and curiosity across Tech, Product, and Design

Why we
  • Become part of one of Europe’s fastest-growing ClimateTech start-ups.

  • Supported by leading US and EU investors, we are shaping the future of the sustainable construction and real estate industry.

  • Modern headquarters in the west of Berlin: conveniently located and well connected.

  • Hybrid work model with flexible working hours.

  • 30 vacation days plus one additional day per year, as well as time off on December 24 and 31.

  • We reward referrals for our open positions through a thoughtful and appreciative referral program.

  • After the probation period: up to five days of educational leave per year with a budget of €1,500.

  • BVG public transport ticket.

  • Membership at Urban Sports Club.
