[Hiring] Staff Software Engineer @Properti

Role Description

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.

Qualifications

• 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

Benefits

• A competitive rate in EUR, matched to the seniority of the role and protected from local currency swings
• Real ownership: You shape the architecture of a platform from day one, and your decisions stay in the product
• A fast-growing company: properti is growing quickly, so your scope and influence can grow with it
• Direct access to decision-makers, a small senior team, and a say in the roadmap
• Freedom in how you work: Remote, flexible hours, and the tools you choose, including AI tools like Claude Code
