Senior Software Engineer

Client

Our client is an established B2B SaaS company building mission-critical software used by large enterprise operators. Their cloud-based platform helps international clients manage complex operational data and make data-driven decisions that improve reliability and reduce costly operational risk. The product is a multi-tenant SaaS solution on a modern Microsoft/.NET stack, integrating with major enterprise systems, and is being extended with AI-powered, predictive features. The company is in a strong growth phase and is actively expanding its engineering teams.

Position

As a
Senior .NET Engineer
, you will own backend-heavy features across the platform end-to-end; from architecture and design through development, testing, and into production. This is a role for an engineer who takes genuine ownership of their work, contributes actively to system design, and cares about how software behaves once it reaches real users in a demanding, mission-critical environment. You will work within a module-based team and play a real part in shaping how the product evolves, including how AI is meaningfully integrated into it.

Responsibilities

• Owning backend-heavy features end-to-end, from architecture and design through development, testing, and into production;
• Building and testing features in C#/.NET within a trunk-based development workflow;
• Using AI coding assistants (e.g., Claude Code, Codex, Cursor);
• Contributing to a thoughtful, product-level integration of AI into the platform;
• Working closely with Product, Design, and a domain expert to translate business needs into reliable implementations.

Candidate

Your background:

• Minimum
  7 years
  of building and shipping software within
  SaaS or enterprise product teams
  ;
• Deep, hands-on C#/.NET expertise, with engineering grounded in clean, well-structured code;
• Knowledge of design fundamentals (SOLID, architectural patterns, pragmatic API design);
• A track record of owning features end-to-end, from the first design decisions through to running in production;
• A plus if you've built or integrated LLM-based features, or know your way around industrial or asset-intensive domains.

Your Stack & Skills:

• AI coding assistants (e.g., Claude Code, Codex, Cursor) are already part of how you work;
• Comfortable with relational databases and at home in a
  cloud environment
  (Azure, AWS, or GCP);
• Familiar with modern engineering practices - CI/CD, containerisation (Docker, Kubernetes), and a strong code-review culture;
• React or another modern frontend framework can be a plus;
• You communicate comfortably in
  Croatian and English
  within an international engineering team.

Your Mindset:

• You take real ownership, care about your features beyond merge, through to how they behave in production;
• You think about the bigger picture: how your code will be tested, deployed, and maintained;
• You are product-aware and understand the business context behind what you build;
• You communicate clearly, collaborate proactively, and approach problems in a structured, pragmatic way.
