- 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
- This isn’t a legacy product handoff: you’ll be joining at the very start, shaping both the technical direction and the team culture from day one
- 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
- We’re actively growing the team and expect to bring on a Product Manager and one additional Engineer alongside you
- 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
- Supporting team leaders with your expertise and assist in customer meetings
- Owning CI/CD pipelines to ensure seamless operations
- In one year, you’ll know you were successful if..
- You are fully integrated as part of the team and have built strong working relationships
- You actively contribute to maintaining a positive, collaborative, and knowledge‑sharing team atmosphere
- You take full ownership of products and solutions, having delivered several major features to production with measurable impact
- 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

- Strong problem‑solving and communication skills
- Familiarity with asynchronous programming and performance optimization in .NET
- Motivational and engaging with a “can do” attitude,



fostering a positive team environment
- 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)
- Ability to collaborate effectively in cross‑functional teams, including product, design, and QA
- Experience with version control systems (e.g., Git) and CI/CD practices
- DevOps experience: CI/CD pipelines, Infrastructure as Code (Terraform, Helm, etc.), Docker, Kubernetes, cloud services (Azure, AWS, or GCP)
- Experience with Python
- Solid understanding of RESTful API design and integration
- Knowledge of microservices architecture and event‑driven systems
- Hands‑on experience with Entity Framework (EF Core) and LINQ
- Familiarity with message brokers (e.g., RabbitMQ, Kafka, Azure Service Bus)
- Awareness of security best practices in software development
- Strong focus on testing practices (unit testing, integration testing, test automation)
- Ability to mentor others and foster knowledge‑sharing within the team
- Proficiency with relational databases, particularly MSSQL and/or PostgreSQL
