About the Role

We're looking for a Senior.NET Developer to join the team building and maintaining our enterprise ITSM and platform automation ecosystem — a suite of ASP.NET Core APIs and services that integrate with directory services, service management tools, and internal data stores, backed by React-based front-end applications. You'll own backend services end-to-end, from design through deployment, and work closely with frontend and automation engineers to deliver reliable, secure, and well-tested systems.

Responsibilities

Design, build, and maintain RESTful APIs and backend services using.NET 8 / ASP.NET Core

Work with PostgreSQL (via Npgsql/Entity Framework) to design schemas, write efficient queries, and manage data access layers

Implement and maintain authentication/authorization flows, including JWT bearer auth, Windows/Negotiate authentication, and LDAP/Active Directory integration

Integrate backend services with third-party and enterprise systems (e.g., ServiceNow-style ITSM platforms, directory services, internal data APIs)

Collaborate with frontend engineers to design clean API contracts consumed by React/TypeScript applications

Containerize services with Docker and support CI/CD pipelines (Jenkins, GitLab CI)

Write unit and integration tests, participate in code reviews, and uphold code quality standards (e.g., SonarQube)

Troubleshoot and resolve production issues across the stack, with structured logging (log4net) and observability practices

Contribute to architecture decisions for new services and the evolution of existing ones

Requirements;

5+ years of professional experience building backend services in C# /.NET (ASP.NET Core preferred)

Strong understanding of REST API design, authentication/authorization patterns, and secure coding practices

Experience working with relational databases (PostgreSQL, SQL Server, or similar) and ORMs (Entity Framework or equivalent)

Familiarity with containerization (Docker) and CI/CD pipelines

Experience with version control (Git) and collaborative development workflows

Strong debugging, troubleshooting, and problem-solving skills

Clear written and verbal communication, with the ability to work cross-functionally with frontend, QA, and infrastructure teams

Nice to Have (Advantages)

Full-stack development experience, comfort working across the stack with React/TypeScript front ends, from API design to UI integration

AI/ML knowledge, familiarity with applying AI/LLM tooling to developer workflows, automation, or product features (e.g., integrating LLM APIs, prompt engineering, or AI-assisted development practices)

Automation experience with Python and/or Ansible Automation Platform (AAP), building or maintaining scripts, playbooks, or jobs for infrastructure automation, compliance checks, or operational tooling

Requirements

Experience integrating enterprise systems with LDAP/Active Directory or similar identity providers

Exposure to hybrid environments where.NET services, Node/React front ends, and Python-based automation coexist and need to interoperate

A track record of improving reliability, security, or maintainability of backend systems in a production environment
