Job description
AI-Native Full-Stack Builder (m/f/d)
Why This Role Exists
We are building an AI-native delivery team that ships working software in days, not quarters. This role is for someone who lives in AI-native tooling — Claude Code, Cursor, Replit, v0, Lovable, Bolt — and who treats shipping as the unit of progress. This is not a Staff Engineer role and is not asking for one. We are not asking for five-year architectural ownership; the integration engineering function owns that. We are asking for speed, judgment, and the ability to ship working software end-to-end at high cadence.
What Success Looks Like
- Working software in users' hands fast — days and weeks, not quarters.
- A portfolio of small, useful internal tools, automations, and tenant-facing PoCs accumulates quickly. Some land, some get killed. Both are signal.
- Tight feedback loops with real users — internal teams, operations, pilot tenants.
- Prototypes that prove themselves are handed cleanly to the integration engineering function for hardening — without rewrite drama.
- Code that did not earn its place is thrown away without ceremony.
Responsibilities
Building & Shipping
- Build working software end-to-end in AI-native tooling: Claude Code, Cursor, Replit, v0, Lovable, or equivalent. You are fluent across at least several of these and you experiment with new ones.
- Ship to small user groups fast — internal users, operations teams, pilot tenants. Your loop is build → demo → learn → rebuild.
- Cover the stack pragmatically: frontend, backend, basic data, basic deploy. You do not need to be the deepest in any one layer; you need to be effective across all of them.
- Build LLM-powered features into product where they create real user or operational value — AI-assisted search, document processing, intelligent summarization, agentic workflows.
Quality Calibration
- Write deliberately loose code in early stages; tighten what proves itself. Recognize when something is a five-day experiment and when it is a candidate for production.
- Throw away what did not work without attachment. Double down on what did.
- Hand winning prototypes to the integration & hardening engineering function with clean context — what it does, who uses it, what it touches, what is not yet production-ready.
- Apply judgment on quality calibration. Prototypes deserve different rigor from production code; both deserve thought.
AI-Forward Workflow
- Use AI coding assistants as your default workflow — code generation, test generation, refactoring, documentation, debugging — not as a novelty.
- Continuously evaluate new AI development tools as they emerge. Adopt fast when they earn it. Discard when they do not.
- Maintain critical judgment over every AI output. Speed without judgment produces bad code at scale.
Your Profile
Experience & Expertise
- 4+ years of professional development experience, or equivalent demonstrated portfolio of shipped work.
- Hard requirement: a working portfolio of AI-built prototypes — at minimum 2 to 3 things shipped recently using AI-native tooling. Link required in application.
- Effective across the stack: frontend (React, Vue, or similar), backend (Node, Python, or similar), basic database work, deployment to platforms like Vercel, Railway, Supabase, or equivalent.
- Daily practice with AI coding assistants — Claude Code, Cursor, or comparable. Not awareness, not occasional use — default workflow.
- Working understanding of when something needs to be hardened versus when it should stay in prototype form. Bonus if you have made that judgment call in production before.
- Comfort with throwaway code and rapid iteration. You do not require comprehensive test coverage on a 3-day experiment.
- Real estate, proptech, or property operations context is an advantage — not a gating requirement, but it accelerates you.
Core Competencies
- Velocity Under Uncertainty: You ship in days even when the spec is fuzzy. You treat ambiguity as a signal to build, not to delay.
- Prototype-to-Production Fluency: You know which corners can be cut and which cannot. You know when to call in the integration engineer.
- AI Tool Mastery: You are deep in at least one AI coding environment and competent in several. You are not a tourist.
- User Proximity: You stay close to the people using your work. The feedback loop is short and direct.
- Comfort with Throwing Code Away: You do not get attached. The portfolio matters more than any single artifact.
- Pragmatic Quality: You apply the right level of rigor for the stage. Experiments and production code get different treatment, by design.
Who You Are
- Builder: You measure yourself in things shipped, not story points moved.
- Allergic to Long Planning Cycles: You would rather build a small bad thing on Tuesday than plan the perfect thing for two weeks.
- Comfortable with Messy Code in Service of Learning: You also know when to clean it up — or throw it out entirely.
- Curious About the Domain: You actively want to understand how a property gets managed, what an operations team does day-to-day, where the friction lives.
- AI-Forward: AI tools are your default, not a novelty. You experiment with new ones every month and have opinions about them.
- Discreet: You handle tenant data and operational information responsibly, including data passing through AI systems.
Qualifications
- Working portfolio of AI-built artifacts shipped in the last 90 days — link required in application.
- English: advanced.
- German: an advantage but not gating.
- Degree not required if portfolio is strong. Demonstrated shipping beats credentials.
Your Perspective (Benefits)
- Interesting, varied and broad range of tasks in one of the largest real estate companies in Germany and Europe.
- Individual training and coaching for professional and personal development in our Academy and with our in-house business coach.
- Professionally equipped, in-house gym with trainers and courses at the headquarters in Berlin as well as fitness and health offers through the Wellhub platform at all external locations.
- Comprehensive company health management and company pension scheme.
- Support on the way to work through a subsidy for the use of public transport and the option of leasing a bicycle through Eurorad.
- Mobility and flexibility through the use of pool cars and company cars to carry out tasks.
- Flexible working hours and mobile working for an even better work-life balance.
- Exciting virtual range of family-friendly benefits, including vacation programs, leisure and sports activities and consulting services with our partner company Voiio.
- Opportunity to attend Bundesliga matches of FC Union Berlin, our favorite club.
- Discounts in selected hotels worldwide with up to 30% on overnight stays and special conditions on food and drinks.
- Employee discounts for special conditions in the areas of media, fashion, leisure, facilities and much more via a partner company.
- Additional days off on Christmas Eve & New Year's Eve.
