Job Beschreibung

Remote · Contractor · Competitive EUR rate · Working language: English

properti is Switzerland's AI-native platform brokerage. More than 12'000 closed transactions give us proprietary data on pricing, buyer behaviour and seller conversion that no software vendor has.

The role

Build the foundations of a new platform from the ground up. You will design its core systems and APIs, set the architectural direction, and build the hardest parts yourself. These APIs will be user-facing and latency-sensitive, and once we ship they will carry real commitments on uptime, reliability, and backwards compatibility. Decisions you make early will have to hold up for years.

You will work directly with our CTO as a technical peer, not as a ticket-taker. This is an individual contributor role with real decision-making authority, and we expect you to spend a large share of your time writing production code.

About us

properti is a Swiss AI-first real estate brokerage. We are a small, senior team with direct access to decision-makers, and we are looking for the engineer who will shape the technical foundations of our new platform.

Aufgaben

You will own:

Domain model and service boundaries: applying domain-driven design (bounded contexts, aggregates, context mapping) to a real, evolving business domain
Conceptualize the API layer: contracts, versioning, authentication and authorization, and gateway design, with APIs that developers genuinely enjoy using
Abstractions that last: defining the abstractions and storage models the platform will grow on as our business logic and expansion needs increase
Security architecture: IAM, service-to-service authentication, secrets management, and threat modeling as a routine part of design
Key technical decisions: build vs. buy, migrations, and technology choices, documented as short design docs (ADRs/RFCs) with clear trade-offs
Critical-path implementation: reference implementations of the hardest components, and reviews of the changes that matter most
The reliability baseline: observability, failure handling, data consistency (idempotency, retries, event-driven workflows), and an on-call experience that gets better over time

Job Anforderungen

What you bring

This is a senior role. If you have fewer than 10 years of experience, or have not been accountable for architecture decisions, it is not the right role yet.

10+ years in software engineering, including at least 4 years as the person accountable for the architecture of a production system
Deep, practical experience applying domain-driven design to a real system, and the ability to explain where it helped and where it did not
Strong TypeScript/Node.js, or equivalent depth in another stack with the willingness to work in ours
Experience designing storage abstractions and data models (PostgreSQL or similar) for scaled backend systems
Experience designing and operating APIs behind a gateway, including authentication, authorization, rate limiting, and versioning
Security you have actually applied: least-privilege IAM, service identity, and threat modeling
Experience designing resilient distributed systems and improving the on-call experience of production systems
Hands-on experience with AWS and containerized deployments
Experience with observability in production (logs, metrics, traces, alerting) and an operator’s mindset
A habit of writing: clear design docs and decisions you can defend
Fluent English, written and spoken. C1 level or equivalent. English is our working language for design docs, reviews, and daily communication
Ownership mindset: you believe there is no such thing as “other people’s code”
The ability to work well with product and engineering colleagues, advocate for what you need, and adjust designs as requirements and feedback change

Nice to have

Event-driven architecture at scale
Experience building a platform that other teams build on
Light frontend exposure (UI work will not be a main part of the role)

Our stack and how we work

Stack: primarily TypeScript, with Next.js and Tailwind CSS on the frontend, and containers on AWS
Tooling: use whatever helps you do your best work, including Claude Code and other AI tools
Language: English first for all documentation, meetings, and written decisions
Async-first, with written decisions
Engagement: contractor (B2B), paid in EUR, with a competitive rate for the seniority of the role

How to apply

Please do not just upload a CV. Send your CV together with short written answers in English (about 300 words each) to the following two questions:

Describe a system whose architecture you owned. What was the hardest trade-off you made, and what would you change today?

Describe a case where a domain boundary you drew turned out to be wrong. How did you find out, and what did it cost to fix?
