Founding Engineer (Full Stack)

Direct message the job poster from Nestra

Shape the future of housing with tech that scales

At Nestra, we're on a mission to radically change how real estate development works. Imagine a world where building homes is as scalable as writing code—fast, intelligent, and on-demand. We're building the tech that makes this a reality.

We’re looking for our Founding Full Stack Engineer — someone who wants to build core infrastructure from scratch, ship fast, and solve real-world problems with code. If you’ve ever wanted to be on the ground floor of something big, this is it.

What You'll Do

• Own the end-to-end development of Nestra’s digital platform — frontend, backend, and everything in between.
• Work directly with the founders to shape the product roadmap and technical architecture.
• Build elegant interfaces and scalable backend systems that support real-world operations.
• Design APIs and integrations that power our automation and connect us to external services.
• Set the foundation for engineering best practices : CI / CD, testing, observability, security.
• Move fast, learn even faster, and help us iterate toward product–market fit.
• Require : 5+ years full-stack experience in fast-paced environments or early-stage startups.
• Builder mentality : love taking ownership and turning ambiguity into working software.
• Technical versatility : fluent with modern frontend frameworks (React, etc.), backend languages (Node.js, Python, etc.), and cloud platforms (AWS, etc.).
• Product-oriented : care about the “why,” not just the “how,” and enjoy collaborating with non-technical stakeholders.
• AI-savvy : curious about and eager to leverage AI tools — from LLMs to automation APIs — to enhance product capabilities and development speed.
• Startup DNA : bias to action, comfort with change, excited to build from zero to one.
• Must already have the right to work in Spain or the EMEA region — no visa sponsorship at this stage.
• While remote-first, our headquarters are in Barcelona. Ideally, you are here or willing to join in person 4 days a month.
• Experience in proptech, construction tech, or digitizing legacy industries is preferred.
• Enjoy working close to physical-world operations (e.g., logistics, real estate, supply chains).

What We Offer

• Founding role : shape the tech, culture, and trajectory of the company.
• Meaningful ownership : startup equity and real skin in the game.
• Competitive compensation : salary benchmarked against leading European tech hubs.
• Tangible impact : our product affects real homes and people.
• Massive opportunity : addressing the housing shortage with scalable, sustainable solutions.
• Aligned team : collaborative builders, architects, and operators committed to solving real problems.
