Senior Python Engineer

We’re hiring a Senior Python Engineer to take a leading role in building the backend technology behind a large-scale digital platform. You’ll be responsible for making important technical decisions, developing core services, and ensuring our systems remain fast, dependable, and ready to grow. The position is highly hands-on and suited to an engineer who enjoys taking ownership rather than working within narrowly defined responsibilities. You’ll work across application development, distributed architecture, messaging, data flows, performance, and production operations. Working hours: This position requires substantial overlap with Central European Time (CET ±2 hours). Candidates must be located within this time-zone range. Applications from outside the stated range will not be considered. Your Responsibilities - Own backend services throughout their lifecycle, from technical design and implementation to deployment, maintenance, and future improvements. - Build and evolve Python/Django services capable of handling substantial traffic and demanding performance requirements. - Contribute to the architecture of distributed systems designed for scale, availability, and consistently responsive user experiences. - Turn product requirements into production-ready technical solutions while working closely with product, frontend, and infrastructure colleagues. - Help raise the engineering standard through thoughtful code reviews, technical discussions, mentoring, and sharing practical knowledge with less-experienced engineers. - Work with key parts of our backend ecosystem, including APIs, Kafka-based messaging, caching mechanisms, and data-processing workflows. - Investigate and resolve performance bottlenecks, with particular attention to throughput, response times, resource usage, and resilience. - Establish and maintain effective automated testing across unit, integration, and performance levels. - Improve how we develop, deploy, monitor, and operate our software, including logging and system observability. - Take part in the engineering on-call rotation and help diagnose and resolve issues affecting production systems. What You Bring - At least 8 years of professional experience developing backend systems with Python, including evidence that you’ve owned substantial technical work through to delivery. - Practical experience with Django and a good understanding of Python’s asynchronous programming model - Hands-on experience operating Apache Kafka in a production environment. - A strong understanding of distributed backend architecture, whether gained through microservices or other distributed-system designs. - Experience packaging and running applications with Docker; practical Kubernetes knowledge is advantageous. - Experience with at least one major cloud platform, with AWS being particularly relevant. - Strong SQL/database skills, especially with PostgreSQL. Experience with NoSQL technologies is beneficial. - Familiarity with automated delivery pipelines, CI/CD practices, and modern software testing approaches. - Experience working with production monitoring and logging solutions such as Prometheus, Grafana, or comparable technologies. - The ability to investigate complex technical problems independently and communicate your reasoning clearly during design and code-review discussions. - Experience with software platforms serving one million or more users is highly valued. - Experience working within Agile development environments. - A strong ownership mindset and a focus on delivering dependable, maintainable software rather than simply completing individual tickets. - Availability to participate in an on-call rotation.
