Python developer in property management software

We're Locus, a small team in Amsterdam building property management software. We know our market, we know what customers need, and we’re ready to build the business. Join us and be part of that journey. If you enjoy building Python applications, collaborating with colleagues, and taking responsibility for features, we'd like to meet you. You'll work with a lean, structured codebase where event sourcing and CQRS are core to the architecture. You'll focus on backend features, business logic, and data, using Python, FastAPI, PostgreSQL, and Redis.

• Turn requirements into an implementation, bringing your own ideas to the solution.
• Develop backend features using event sourcing to model business processes and record changes.
• Write maintainable code and domain-focused tests that validate business flows and document how they should work.
• Work with domain experts to validate features, then iterate on their feedback.
• Mentor colleagues and offer guidance on technical decisions, helping the team achieve more together.

• Strong experience building and maintaining Python applications, ideally with FastAPI and event sourcing.
• A good understanding of relational databases, transactions, backend design, and the tradeoffs behind architectural decisions.
• Thoughtful collaboration: share your thinking, listen to colleagues, follow through on commitments, and ask for help when you need it.
• You're eligible to work in the Netherlands without requiring sponsorship.
• Будет плюсом: Experience integrating cloud AI services, such as Gemini, Claude, or Amazon Bedrock, into application workflows; React experience is a plus, but isn't required

• 25 days of annual leave, plus national holidays.
• Salary reflects your relevant experience and the responsibilities you take on, with 8% holiday allowance on top.
• We share the salary range before our introductory call.
