What You'll Do In this role: Your work will be split roughly 30/70 between product support within the team's ownership area - third-line tickets, performance incident investigation, and defect fixes - and building new platform features and optimizations. You will own platform feature development end to end: technical design, implementation, merge procedures, and maintenance primarily on the web backend. You will work with Business Analysts on detailed specifications and with QA engineers throughout delivery. You will run peer reviews and hold the bar on technical design, code quality, maintainability, and performance. Tech stack: C# / .NET / SQL Server A few concrete examples of our projects: We investigate customer performance incidents using telemetry, logs, and production artifacts to locate the cause of degradation or crashes. On the tooling side, we are building AI agents that automatically analyze logs, telemetry, and memory dumps to accelerate this work. Performance benchmarking is an open methodological problem: customer workloads vary widely in usage patterns, and customer databases differ in size and structure. Keeping the benchmark suite representative under that variance is what we are working on. AI tools, including Claude Code, are part of day-to-day development and routine task automation. AI capabilities inside the product are a current direction. The most concrete piece is AI-assisted tooling for the large body of customer customization code that extends the platform. Among other directions, we work on developer tooling, code parsers, static analysis, code quality enforcement, and platform extensibility for third-party plugins. Our work is planned and estimated in advance, tasks are well defined, and we do not operate through constant context-switching or overtime. We are looking for candidates who can demonstrate: 7+ years of professional software development experience with .NET, C#, and MS SQL Server , primarily in backend web applications. At least 2 years in a senior or lead engineering role. Experience at a product company with a sizable, mature engineering organization. Experience working on ERP, CRM, accounting, document management, or other business systems. Independent experience designing and developing platform-level functionality. Experience building custom components or infrastructure where standard libraries and off-the-shelf solutions were not sufficient. Genuine interest in the internal mechanics of the technologies you use: the .NET runtime, database servers, and related infrastructure. Hands-on experience with performance profilers, memory profilers, performance optimization, memory dump analysis, performance incident investigation, and telemetry analysis. Demonstrated ownership: acting as a technical driver for projects end to end. Awareness of the business impact of technical decisions, not just their technical merit. Bonus points for: Experience with cloud technologies, particularly Azure or AWS. Experience using AI tools for development productivity and code quality. Experience integrating AI functionality into software products. Experience designing extensibility frameworks and plugin systems. Experience with code parsers, static analysis, or developer tooling. **The title and salary will be discussed with a successful candidate depending on the level of experience. ***We are open to work from home, hybrid or fully on site working model from our office in Belgrade depending on the candidate's preference
