Job technologies
Your role in the team
- We are growing our .NET engineering team and are in a search of senior full-stack engineers.
- The team builds the Invoicetrack platform, from the back-end services to the interfaces customers work in, in close collaboration with product management.
- You are a senior engineer with real ownership.
- You design, build and run what you ship, and you help shape how the team works.
- One of these roles carries stronger technical leadership: setting standards, guiding design decisions and raising the quality of the whole team.
- Work with AI agents daily.
- Tools such as Claude Code and GitHub Copilot are your default way of working, and you know what to delegate and when to take the wheel.
- Own what AI produces.
- You give agents clear context and review their output critically, accountable for its correctness and security.
- Writes AI ready specs with testable acceptance criteria before any code is written.
- Hands whole tasks to AI coding agents and checks the output against the spec.
- Has the agent write tests first; nothing merges until CI and coverage checks pass.
- Reviews by outcome, not line by line, and improves the team’s shared skills and conventions.
- Raise the team’s game.
- Share prompts, tools, skills and workflows that work.
- In the technical leadership role, set the standards for how the team works with AI.
- Ship software finance teams rely on.
- Build across the stack.
- Design and deliver features end to end, from .NET 10 services and RESTful APIs to React front ends, and agree clear API contracts with the front-end engineers you build them with.
- Shape the architecture.
- Lead back-end architecture and data modelling decisions on SQL Server, applying clean architecture and domain-driven design so the platform stays scalable, fast and maintainable.
- Set the quality bar.
- Establish coding standards and best practices through code review, design discussion and example, and give feedback that helps other engineers improve.
- Work with product.
- Turn product problems into technical solutions with the product manager, and push back when there is a simpler or better way.
- Run what you build.
- Work with DevOps on CI/CD pipelines, Docker and Kubernetes deployments and monitoring, and keep improving the performance, security and scalability of services in production for enterprise customers.
- Grow the team.
- Share knowledge, support other engineers and help hire the people who join after you.
Our expectations of you
Qualifications
- You are also comfortable working with legacy systems on .NET Framework 4.8.
- An AI-first way of working.
- You use AI tools such as GitHub Copilot and Claude as your default in daily development, not occasionally.
- You work well with engineers, product managers and DevOps, and you make the people around you better.
- You are at home in Jira and Confluence.
- You want to make a difference, take ownership and hold yourself to a high standard.
- A track record of setting standards or leading technical decisions is a strong plus, and essential for one of the two roles.
- Excellent English, written and spoken.
Experience
- Senior .NET experience.
- 5+ years building production back-end systems in C#, ASP.NET and Entity Framework, including .NET 10, with strong fundamentals in performance and a real affinity for good code design, refactoring and testability.
- Strong experience designing RESTful APIs and distributed systems, working with Elasticsearch, Kafka, Docker, Kubernetes and various Azure services, and building on relational databases such as SQL Server.
- Hands-on experience with React and TypeScript, including state management libraries and integrating front ends with back-end APIs.
- Experience with xUnit or NUnit and integration testing, and a working understanding of CI/CD pipelines.
- Experience with SaaS platforms is a plus, though not required.
What we offer
- The minimum gross salary for this position is €3,954 per month, as determined by the IT Collective Agreement.
- The actual salary will be based on your qualifications and experience.
