We’re launching a new team dedicated to modernizing and expanding one of our customer-facing tools — and we’re looking for a Senior Full Stack Engineer to help build it from the ground up The current stack is Vue.js on the frontend and Python on the backend, but we’re planning a migration to .NET in the near future As the senior engineer, you’ll take a leading role in architecture decisions, technical direction, and mentoring as the team grows You’ll be one of the founding members of a brand-new team, led by our Tech Team Lead This means you’ll have real influence over how the team is structured, how we work, and the technical foundations we build on — it’s a rare chance to help define a team’s culture and practices from the very beginning, rather than stepping into something already set Developing and maintaining applications, including front‑end interfaces, back‑end services, and databases Contributing to the architecture, design and implementation of new features and improvements Implementing best practices for code quality, testing and deployment automation Ensuring high‑quality software through active participation in code reviews Actively engaging in sprint retrospectives, refinements, daily stand‑ups, and other team processes Taking full ownership of the products and solutions you develop, eliminating bugs early in the process through TDD/BDD and other tests Leveraging AI‑assisted development tools and workflows to increase engineering velocity, while maintaining code quality and rigor Sharing knowledge and supporting fellow developers, QA professionals,



and support teams You share your expertise by mentoring mid‑level and junior developers, helping them grow and succeed You contribute to improving team processes, code quality, and technical decision‑making Because of this, we’re looking for someone comfortable working across all three — Vue, Python, and .NET — who can help drive that transition while continuing to ship new feature Familiarity with asynchronous programming and performance optimization in .NET Comfortable working in agile development environments and participating in sprint planning, code reviews, and peer mentoring Extensive experience with C# and the .NET ecosystem (.NET Core/.NET 6+, ASP.NET Web API, etc.) Responsible for front‑end codebases using Vue.js and/or TypeScript, collaborating closely with full‑stack and frontend developers Sound understanding of frontend build tools and state management (Vuex, Pinia, or similar) Solid understanding of software architecture, design patterns, and best practices Experience with automated testing frameworks (unit, integration, and end‑to‑end) Experience with version control systems (e.g., DevOps experience: CI/CD pipelines, Infrastructure as Code (Terraform, Helm, etc.), Docker, Kubernetes, cloud services (Azure, AWS, or GCP) Experience with Python Hands‑on experience with Entity Framework (EF Core) and LINQ RabbitMQ, Kafka, Azure Service Bus) Awareness of security best practices in software development Strong focus on testing practices (unit testing, integration testing, test automation) Proficiency with relational databases, particularly MSSQL and/or PostgreSQL #
