You'll ideally have around 5+ years of software engineering experience, with a strong backend background and good experience with Python. You don't need to have worked in cybersecurity before. What matters more is that you're comfortable working with: * Python and backend systems * Large amounts of data * Data pipelines and databases * Cloud platforms - AWS would be ideal, but Azure or GCP are also relevant * Containers and/or serverless technologies * Technical design and architecture * Complex problems where there isn't always an obvious answer ## Description We're working with a growing technology business that is looking for a Senior/Principal Python Engineer to join its Belfast engineering team. This is a role for someone who enjoys getting stuck into backend engineering, data and architecture, rather than simply working through a list of tickets. The team is working on some major changes to the platform, so there is a good opportunity for someone senior to have a real say in how things are built. What's the role about? At a high level, you'll be working on the backend systems and data pipelines that sit behind the wider platform. There's a lot of data involved, so a big part of the challenge is making sure it can be ingested, processed, organised and stored efficiently at scale. The technology is primarily Python, alongside cloud technologies, databases, containers and serverless architecture. The team is also going through a period of change and improvement, so you'll be involved in things like reworking the ETL platform, developing a new stateful backend and building out a Knowledge Database. There's also the added challenge of supporting the platform across different environments, including cloud, on-premise and government environments., This isn't a role where you'll simply inherit an established platform and maintain it. The team is actively changing and improving the architecture, meaning someone joining at Senior/Principal level can have a genuine influence on the direction of the technology. ## Related Videos - [30 powerful AWS hacks in just 30 minutes: Boost your developer productivity](https://www.wearedevelopers.com/videos/1624-30-powerful-aws-hacks-in-just-30-minutes-boost-your-developer-productivity) - [Developing the Backend with Stefan Lingler, CTO at Shpock](https://www.wearedevelopers.com/videos/100360-developing-the-backend-with-stefan-lingler-cto-at-shpock) - [Kubernetes and Microservices with Multi-Model Databases](https://www.wearedevelopers.com/videos/382-kubernetes-and-microservices-with-multi-model-databases) - [Why and when should we consider Stream Processing frameworks in our solutions](https://www.wearedevelopers.com/videos/1085-why-and-when-should-we-consider-stream-processing-frameworks-in-our-solutions) - [Python-Based Data Streaming Pipelines Within Minutes](https://www.wearedevelopers.com/videos/1233-python-based-data-streaming-pipelines-within-minutes) - [Shipping Faster with Less: Render on Cloud Hosting, AI Workloads, and the Future of DevOps](https://www.wearedevelopers.com/videos/1894-shipping-faster-with-less-render-on-cloud-hosting-ai-workloads-and-the-future-of-devops) ## Related Articles - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [Why Upskilling And Reskilling is Important For Developers](https://www.wearedevelopers.com/magazine/428-why-upskilling-and-reskilling-is-important-for-developers) - [The 13 Best Python Libraries for Developers in 2025](https://www.wearedevelopers.com/magazine/371-the-13-best-python-libraries-for-developers-in-2025) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [The Most Popular IT Jobs on the Market](https://www.wearedevelopers.com/magazine/376-the-most-popular-it-jobs-on-the-market) - [Data Engineer Salary UK](https://www.wearedevelopers.com/magazine/253-data-engineer-salary-uk)
