Senior .NET Software Engineer (m/f)

Opis posla

        We’re looking for a Senior .NET Software Engineer to join Aircash Development in Split. You’ll own complex backend problems from idea to production – designing and building the systems behind our products, writing clean, scalable code, and shipping features that reach millions of users across the EU.

Split is a new Aircash Development location, not a separate engineering organization. Your team will work with the same standards, culture and ways of working as the rest of Aircash Development – one engineering organization, multiple locations.

Key Responsibilities:
- Own complex backend features end-to-end, from technical design and implementation to production monitoring and continuous improvement
- Drive technical discussions, challenge solutions constructively, and help the team make pragmatic engineering trade-offs
- Support and mentor other engineers, share knowledge and context, and help raise the engineering bar across the team
- Take ownership when things go wrong in production – lead the investigation, fix the root cause and share what we learn
- Work through ambiguity: turn unclear problems into clear technical solutions without waiting for a perfectly defined task
- Design, develop, and maintain backend services and APIs using modern .NET technologies, writing clean, scalable code
- Participate in code reviews and provide constructive feedback to peers
- Collaborate closely with QA engineers to ensure comprehensive testing coverage and smooth deployments
- Work alongside the product team to refine requirements and deliver features that exceed user expectations
- Contribute to system monitoring, logging, and performance tuning to ensure system reliability and observability
- Test, deploy, and monitor your work – your contributions will be immediately visible to users
- Stay up to date with new technologies, concepts, and best practices in software development, and bring them to the team
- Work with established development tools, guidelines, and conventions, including:
          - Web development using .NET Core or .NET Framework
          - Relational databases (MSSQL) and Object-Relational Mapping (ORM) tools like Entity Framework (EF/EF Core)
          - Build and maintain integrations with NoSQL systems like Elasticsearch and cloud-based components, such as Azure Service Bus
          - Basic understanding of frontend frameworks, with AngularJS being a plus

Uvjeti:
- 5+ years of professional .NET development experience, with deep knowledge of .NET Core / .NET Framework
- A track record of taking complex problems from requirements to production and owning the outcome, not just the assigned task
- Experience making technical decisions, understanding trade-offs, and challenging solutions constructively
- Experience mentoring less experienced engineers and sharing context, not just code
- Comfort working through unclear requirements and taking initiative without waiting for tasks to be defined
- Strong understanding of backend architecture patterns, microservices, RESTful APIs, and asynchronous -processing
- Strong problem-solving skills and a proactive approach to tackling challenges
- Familiarity with distributed systems, messaging platforms (e.g. Azure Service Bus), and event-driven architectures
- Understanding of observability concepts (logging, tracing, metrics) and tools like New Relic, Seq, or similar
- Excellent communication and collaboration skills to thrive in a team-oriented environment
- Commitment to delivering high-quality, scalable solutions focusing on user satisfaction

Benefiti:
What we bring to the table.

Innovation drives us, and we never stop asking "what's next?".

And because great work deserves great perks, here's what you can expect from day one:
- Growth isn't a buzzword here. You'll have access to real learning opportunities, both inside and outside the company
- Open feedback is part of our culture; we grow by listening, learning and sharing with each other
- Tasty, freshly prepared lunches every day, with options to suit different tastes and preferences
- Start your day off right – coffee, tea, fresh fruit, and snacks are waiting for you every morning in the kitchen
- Annual health check-ups to help you take care of your health without extra hassle
- A fully covered Multisport card and sports activities like padel to make staying active easy and enjoyable
- Christmas and Easter bonuses that bring a little extra ease to the holiday season
- For parents, extra support and time off for those milestone moments – from baby bonuses to the first days of kindergarten or school
- Extra vacation days to give you more time to unwind, recharge and do what you enjoy most

Step into a role where your ideas make an impact, your work has meaning, and every day brings something new to build or improve.
