You will take ownership of shaping agentic AI solutions end-to-end — from API architecture and system design to comprehensive testing strategies — while mentoring peers and championing a collaborative, quality-driven engineering culture.

Responsibilities

• Architect and develop robust backend services in .NET (C#) to expose AI/model capabilities via APIs (REST/gRPC) for consumption by front-end and downstream applications.
• Lead the design and implementation of Angular UI components that surface AI-driven features such as chat interfaces, recommendation panels, and agent status/monitoring dashboards within existing or new applications.
• Define and enforce secure, scalable, and maintainable integration patterns between AI services and core business applications.
• Design, write, and optimize stored procedures, queries, and ETL processes to support data pipelines feeding AI models.
• Establish automated testing frameworks using Playwright for UI/end-to-end testing of AI-integrated application features.
• Define and implement testing strategies specific to AI/agentic systems, including prompt regression testing, output validation, agent behavior testing, and edge-case/adversarial testing.
• Lead code reviews, own CI/CD pipeline maintenance, and drive release quality gates.
• Mentor mid-level engineers and contribute to technical decision-making across the team.

Qualifications

• 3+ years of professional experience in full-stack development, with a proven track record in AI integration.
• Strong proficiency in C# and .NET for backend service development and architecture.
• Deep expertise in Angular for building modern, responsive, and scalable front-end components.
• Advanced skills in Gen AI-assisted development to accelerate coding and integration workflows.
• Extensive background in Microsoft SQL Server, including stored procedures, query optimization, and ETL processes.
• Proven competency in Playwright and test automation development within the JS ecosystem.
• Solid understanding of secure, scalable integration patterns between AI services and enterprise applications.
• Experience mentoring engineers and leading technical initiatives.
• Proficiency in English at an Upper-Intermediate level (B2) or higher.

Nice to have

• Hands-on experience with Amazon Web Services for cloud-based deployments.
