architecture, leveraging microservices patterns, and running entirely on

Azure Cloud

. We use

RabbitMQ

to build resilient, event-driven services. Implement comprehensive test suites, leveraging

Test-Driven Development (TDD)

practices with

xUnit

and/or

NUnit

structured logging

and our existing toolset,

including Grafana, Prometheus, Elasticsearch, Kibana, and distributed tracing

. Conduct

performance and load testing

using tools like

k6

or

JMeter

to ensure service resilience and scalability.

Contribute significantly to our DevOps practices, focusing on the entire CI/CD pipeline within Azure DevOps, including reviewing and improving code and deployment documentation, and ensuring robust Kubernetes (AKS) deployment, configuration, and maintenance.

Collaborate closely with our

Flutter

frontend developers, product managers, and other stakeholders to deliver high-quality features. Participate in and lead code reviews, providing constructive and insightful feedback. Create and maintain comprehensive

technical documentation

for services, APIs, workflows, and infrastructure components.

Must-Have:

7+ years

of backend development experience with

.NET

. Deep understanding of

Modular Monoliths, Microservices

,

Event-Driven Architecture (EDA)

, and sophisticated

API design (REST/gRPC)

. Proven expertise in designing and optimizing relational databases, specifically

MS SQL Server

(including advanced topics like indexing, performance tuning, and schema design).

Strong experience with Azure Kubernetes Service (AKS)

and containerization technologies like

Docker

in a production environment. Expertise in

Test-Driven Development (TDD)

and proven experience writing robust tests using

xUnit, NUnit

, or a similar .NET testing framework. Hands-on experience with advanced monitoring and observability tools:

Grafana, Prometheus, Elasticsearch, Kibana

, and a strong understanding of

Structured Logging

and distributed tracing.

Experience with Azure DevOps for managing CI/CD pipelines.

Familiarity with

Infrastructure as Code (IaC)

using

Terraform or Bicep

. Solid understanding of

security best practices

in backend and cloud environments. Comfortable working in a remote, Agile/Scrum-based environment.

Nice-to-Have:

Extensive experience with the

ABP framework

is a significant advantage. Prior experience working closely with a

Flutter

mobile frontend team. Experience with high-traffic, high-availability, customer-facing applications (especially in social or media domains). Experience with

methodologies and tools like

k6

or

JMeter

. Microsoft Azure certifications (e.g., Azure Developer Associate, Solutions Architect Expert).

Why Join Us?

Be part of a product with exciting technical challenges and a real global impact.

100% remote

-- work from anywhere. A chance to shape not just code, but the overall
