Staff Software Engineer 100% Remote – Ankara

About the role

properti, a Swiss PropTech broker, is hiring a Staff Software Engineer for a fully remote position based in Ankara. This is a senior role focused on owning the architecture of a platform, with a competitive hourly rate paid in EUR and a contractor (B2B) engagement.

Key responsibilities

• Define domain boundaries and service boundaries using domain-driven design (bounded contexts, aggregates, context mapping)
• Design the API layer: contracts, versioning, authentication and authorization, and gateway design
• Define storage models and abstractions that the platform can grow on
• Handle security architecture: IAM, service-to-service authentication, secrets management and threat modeling
• Make key technical decisions (build vs. buy, migrations, technology choices) documented in ADRs/RFCs
• Build reference implementations of critical components and review the most important changes
• Set the reliability baseline: observability, failure handling, data consistency, idempotency, retries, event-driven workflows and an on-call experience

Required profile

• 10+ years in software engineering, including at least 4 years accountable for the architecture of a production system
• Deep practical experience with domain-driven design and with storage abstractions and data models (PostgreSQL or similar)
• Experience designing APIs behind a gateway, resilient distributed systems and on-call improvements
• Hands-on experience with AWS and containerized deployments, and observability in production
• Fluent English (C1 or equivalent); English is the working language
• Ownership mindset and good collaboration with product and engineering colleagues
• Nice to have: event-driven architecture at scale, platform-building experience, light frontend exposure

Required skills

• TypeScript and Node.js, or equivalent depth in another stack
• API design, IAM, threat modeling, AWS and containers
• Next.js and Tailwind CSS on the frontend

What we offer

• A competitive rate in EUR, matched to seniority and protected from currency fluctuations
• Direct access to decision-makers and a say in the roadmap
• Remote, flexible hours and freedom to choose your tools, including AI tools

To apply, send your CV together with two short written answers in English (about 300 words each) describing a system you owned and a case where a domain boundary proved wrong.
