We are looking for a Senior .NET Engineer who brings not only deep technical expertise but also the mindset and capabilities of a Technical Lead. 

You’ll take on Technical Lead responsibilities in selected projects, offering technical direction, mentoring, and ownership-where your leadership will bring the most value. In other projects, you may focus solely on your senior engineering role, continuing to code and deliver with excellence. 

In short: you’re a Senior Engineer with Technical Lead skills - and when your leadership strengths are needed we won’t hesitate to let you lead, while also giving you space to stay hands-on when the team or the project benefits most from your engineering focus. 

Your Skills and Experience: 

• 5+ years of professional experience in C# and .NET development 
• Proven track record in designing and building distributed applications in production environments 
• Strong understanding of Agile methodologies and modern software development practices 
• Solid experience in DevOps-related areas (CI/CD, automation, containerization, monitoring) 
• Proficiency in applying modern programming paradigms, architectural patterns, and best practices 
• Strong design, development, and troubleshooting skills across diverse application architectures 
• Experience with React or other modern frontend frameworks as part of full-stack delivery will be considered a strong plus. 
• Readiness to work across technologies -openness to C++, Python, Java or others, depending on the domain. 
• Fluent English, both spoken and written - essential for working in international teams and with global clients 

Your soft skills matter too:

• A proactive attitude and ownership mindset – you take initiative and focus on solutions, not excuses 
• Self-awareness and ambition – you know your strengths, seek feedback, and continuously improve 
• Adaptability and curiosity – you're not afraid to step outside your comfort zone when needed 
• Collaboration-first approach – you support your teammates, share knowledge, and help build a strong team culture 
• A sense of responsibility – you care about the outcomes for your team, your project, and the client 

What You’ll Be Responsible For:

• Designing, developing, and maintaining robust .NET-based applications and backend services 
• Building full-stack solutions, including frontend components when applicable (e.g., in React) 
• Collaborating effectively within cross-functional teams. 
• Applying engineering best practices: code reviews, unit testing, design patterns, DevOps principles 
• Contributing to both current and future product architecture and design decisions 
• Collaborating closely with developers, QA engineers, and product stakeholders to deliver value 
• Ensuring high code quality and mentoring less experienced colleagues through feedback, pairing, and technical guidance 

If the project calls for it, you will step into the Technical Lead role and: 

• Provide technical direction and oversight for the project 
• Collaborate with our customers, product team, and internal stakeholders 
• Define goals, estimate workload, and support planning activities 
• Shares opinions and ideas on tools, technologies, or architectural approaches within their area of expertise, helping to inspire direction and improvements. 
• Proactively manage risk, dependencies, and progress tracking 
• Contribute to key decisions around technology, delivery approach, and team development. 
• Act as a mentor and leader, promoting technical excellence and continuous improvement within the team 

At Macrix, we value people who take initiative, support their teams, and care about delivering real value to clients. If you're someone who enjoys solving tough problems, shaping the way we grow, and being part of a collaborative, forward-thinking culture- we’d love to hear from you. 

We’re especially looking for candidates based in Poznań or nearby areas, who would enjoy the opportunity to work from our office 2–3 times a week. While we value flexibility, we also believe in the power of in-person collaboration – especially on complex and high-impact projects.
