ABOUT NUMA

Hey there! We’re Numa, a forward-thinking hospitality brand redefining how people discover cities. We create spaces where simplicity meets innovation, offering thoughtfully designed rooms, studios, and apartments in the heart of Europe’s most vibrant neighbourhoods.
We’re not just transforming the guest experience—we’re revolutionizing the hospitality industry from the inside out. Our cutting-edge technology streamlines operations, delivering unparalleled value with no hidden fees—just real, quality experiences.
At Numa, we believe that travel should be curious and authentic, and we bring those same values to our work culture. As part of our team, you’ll experience a dynamic and supportive environment where creativity thrives, and your contributions make a real impact. We’re committed to fostering a diverse, inclusive, and equitable workplace where every voice is valued, and different perspectives fuel our innovation.

ABOUT THE ROLE

  1. Design & Brand Evolution
  • Collaborate directly with the Head of Design and regional Design Managers to develop an on-brand aesthetic that harmonises Numa’s Brand aesthetic and the local neighborhood vibe.
  • Support our Research & Development team on brand concept updates and FFE (Furniture, Fixtures, and Equipment) innovations.
  1. Technical & Operational Excellence
  • The Technical Gatekeeper: Review and approve construction documentation and specifications from external landlords, architects, and contractors. You ensure their work doesn't compromise our design intent.
  • Tender Mastery: Prepare full tender sets for the project FFE scope—including layouts, technical drawings, and specifications.
  • The Quality Benchmark: Partner with regional Project Managers and conduct site visits to ensure the physical product aligns perfectly with our design quality and vision.
  1. Commercial Collaboration
  • Budget Stewardship: Align closely with the Procurement team to ensure your design proposals and FFE specs meet budget targets without losing their "wow" factor.
  • Strategic Programming: Work with Real Estate, Revenue, and Operations teams at the start of a project to develop space programs tailored to each specific market.

ABOUT YOU

  • The Hospitality Expert: 5+ years of experience in Interior Design/Architecture, with a strong background in hospitality or multi-unit residential projects.
  • The Revit Pro: Proficiency in Revit and Enscape is a must. You are comfortable building technical sets and navigating BIM workflows.
  • The German Connection: You speak and write German fluently. This is essential for reviewing legal construction documentation and communicating with local partners.
  • The Agile Leader: You have experience mentoring junior team members and a "can-do" attitude that thrives in a fast-paced environment.

ABOUT OUR OFFER

  • Empower your career: Thrive in a fast-paced, collaborative environment where your ideas help shape our future. Enjoy opportunities for professional growth and build a fulfilling career path.
  • Experience our brand: Immerse yourself in the Numa lifestyle with a complimentary stay. Share the love with friends and family through exclusive discounts on our stylish apartments. Connect with a global community of colleagues at our inspiring team-building events.

Numa values the diversity of the people it hires and serves. Diversity at our company means fostering a workplace in which individual differences are recognised, appreciated, respected and responded to in ways that fully develop and utilise each person’s talents and strengths. We therefore welcome applications from people of all races, ethnicities, disability statuses, ages, religions, gender identities, and sexual orientations.
