The posting

Senior .NET Developer (C#/.NET) - Hybrid Porto (2 days/week office)

ABOUT THE OPPORTUNITY

We're looking for a Senior .NET Developer to join a well-established international organization in the telecommunications sector, working on business-critical systems that support large-scale operations. This is a chance to take real end-to-end technical ownership, working from architecture and design through to production support, on a team that values engineering craft, pragmatic decision-making, and mentorship over process for its own sake.

PROJECT & CONTEXT

You'll join the engineering team behind a large-scale telecommunications platform for an international company with operations across Europe. The team designs and evolves scalable, distributed C# .NET solutions, with modern DevOps practices — CI/CD via Azure DevOps, Infrastructure-as-Code with Terraform, and observability tooling — embedded directly into the development lifecycle. You'll work closely with Tech Leads, QA, and Product to deliver reliable features end-to-end, while helping raise the engineering bar through code reviews, pairing, and mentoring junior and mid-level engineers.

WHAT WE'RE LOOKING FOR (Required)

  • 5+ years of professional software engineering experience with a proven track record operating production systems at scale
  • Deep proficiency in C# and modern .NET development
  • Strong experience designing and deploying solutions in an Azure Cloud environment
  • Solid understanding of distributed systems, APIs, and scalable architecture patterns
  • Experience implementing CI/CD pipelines and automated deployment strategies (Azure DevOps)
  • Demonstrated experience owning the design of distributed systems and leading engineers across teams without direct authority
  • Proven ability to mentor and elevate other engineers through pairing and code review
  • Strong testing practices across unit, integration, and UI automation, with thorough code review habits
  • Experience working in Agile delivery teams with ownership of technical outcomes
  • Bachelor's or Master's degree in Computer Science, Engineering, or a related field (or equivalent practical experience)
  • Fluent English, B2 (Upper Intermediate) minimum — required

NICE TO HAVE (Preferred)

  • Experience with React, HTML, CSS/SCSS for front-end collaboration
  • Familiarity with Docker and containerized environments
  • Experience with observability stacks such as Prometheus, Grafana, Loki, or Azure Application Insights
  • Experience using AI-assisted development tooling (e.g., GitHub Copilot, MCP servers)
  • Hands-on experience with Terraform / Infrastructure-as-Code

Want me to save this to the project as a doc, or produce a second version assuming Consulting (or Direct Hiring) with a placeholder minimum you can fill in?

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
