Popis pozice: We are currently looking for talent to join a fast-growing Czech FinTech environment (non‑bank lender) that is entering a new phase: evolving a fast-moving startup product into a stable, sustainable enterprise platform. The role involves supporting an existing legacy system while helping build a modern, next‑generation solution in parallel – and we’re expanding our team to drive this transition. Joining this team means working with a modern tech stack, shaping architecture, and influencing how a proven startup grows into a long-term, resilient product. As a Python Engineer, you will: - design product architecture and implement simple and complex features - suggest improvements across technical and product areas - help break down epics and provide technical estimates - work closely with other developers, QA engineers and managers - work with business consultants to understand and address needs of business What skills should you have? - senior-level back-end Python programming with a proven track record of delivering systems to production - developing clean modules and maintaining high code clarity - designing and implementing backend services and APIs - thinking in terms of maintainability, clarity, and long-term evolution of systems - hands-on experience with MongoDB or similar document databases - understanding of message queues and event-driven communication patterns - ability to quickly learn new frameworks, tools, and patterns when needed - have strong testing culture: write unit (component, integration, and end-to-end tests when applicable) for your features - using type checking and static analysis as part of daily workflow - ability to provide thoughtful, constructive code reviews and have commitment to engineering excellence Additionally it would be great if you: - have experience in FinTech / lending / payments domain - have experience with AWS (or GCP, Azure) services and cloud infrastructure - have solid Docker skills and understanding of containerized environments - are able to work with CI/CD systems (GitHub, GitLab) and are not afraid to write/setup pipeline yourself - are comfortable with infrastructure-as-code and automation practices Tech stack - tools that we currently use or plan to use in the future: - Python 3.1X, FastAPI, Pydantic, Pytest, Mypy (we’re planning to try 'ty') - ruff, uv, Docker, AWS (SDK, CDK, CloudFormation, EC2, ECS, Fargate, S3, Dynamo, Kinesis, SQS, AWS Lambda, CloudWatch, SSM) - OpenTelemetry, Prometheus, Grafana, Ansible, GitLab CI/CD What we offer: * Meaningful Technical Growth - deep, hands‐on work with modern Python tooling and cloud technologies - real ownership of architecture and long‐term technical direction * Build Engineering Culture You Can Be Proud Of - strong focus on code quality, clarity, and maintainability - pragmatic decision‐making — no over‐engineering, no unnecessary bureaucracy - a team that is actively shifting toward thoughtful engineering over rushing features * High Impact on the Product - direct influence on architectural decisions and system evolution - close collaboration with product and business teams * Flexible, Modern Work Environment - fully remote work setup with flexible working hours with the ability to collaborate during CET business hours - async‐friendly communication that supports deep work - international team with diverse perspectives and experience * Compensation & Benefits - competitive salary and yearly bonuses - paid time off and sick-days This role may not be a good match if: - you need close guidance, step‐by‐step direction, or struggle to self‐organize your work - ambiguous requirements frustrate you, or you prefer others to fully define solutions before you start - writing tests feels like overhead, or you tend to ship features without strong test coverage - you resist code reviews or see them as a formality rather than a collaborative quality practice - cloud infrastructure makes you uncomfortable, or you avoid DevOps‐related tasks even when they’re simple - async communication feels slow or difficult, and you rely heavily on synchronous discussions to move forward - you prefer sticking to familiar tools and patterns rather than learning new ones when the situation calls for it - you avoid ownership, or you tend to over‐engineer or under‐engineer solutions instead of aiming for pragmatic clarity
