Job description

Senior .Net/DevOps Software Engineer (Payroll or Freelance)

Brainsquare is looking for a Senior .NET / DevOps Engineer to strengthen our Product Compliance Team within one of our enterprise environments.
In this role, you will play a pivotal part in building and running a Supplier Compliance Portal - combining backend engineering with cloud-native DevOps expertise to deliver a secure, scalable, and high-performing solution.

This opportunity is ideal for someone who thrives in both .NET development and cloud infrastructure engineering, and who enjoys working in an environment where automation, security, and scalability are central.

Key Responsibilities

• Phase 1 – Foundation & Security

  • Design, build and deploy .NET Core microservices and APIs in Azure.

  • Configure Azure App Services / AKS, implement CI/CD pipelines, monitoring and alerting.

  • Set up secure authentication flows (B2C, SSO, regional authentication such as WeChat).

  • Establish rollback, backup, and restore strategies to ensure high availability.

• Phase 2 – Scaling & Integrations

  • Extend the backend with supplier data services and event-driven integrations (Kafka / Event Hubs).

  • Optimize system performance for 5,000+ concurrent users through caching, replication, and load balancing.

  • Strengthen infrastructure with observability dashboards and proactive performance tuning.

  • Collaborate closely with React frontend engineers to ensure end-to-end secure and performant data flows.

• Phase 3 – Reporting & Advanced Workloads

  • Scale infrastructure to handle complex compliance data queries and “where-used” scenarios.

  • Support reporting pipelines and optimize data query layers.

  • Continuously improve the production environment through advanced DevOps practices and automation.

What we expect from you

• Proven experience in .NET development (C#, APIs, microservices).

• Strong knowledge of Azure Cloud services (App Services, Azure SQL, Blob Storage, Key Vault, Entra ID).

• Hands-on experience with CI/CD pipelines in Azure DevOps.

• Familiarity with event-driven architectures (Kafka, Event Hubs).

• Solid expertise in cloud security, identity, and resilience (OAuth2/OIDC, RBAC, rate limiting, rollback strategies, disaster recovery).

• Ability to design, implement, and maintain scalable enterprise-grade backends.

Bonus points for:

• Experience with performance/load testing, AI/ML integration, or fullstack development (React).

What we offer to employees

• A permanent contract with a competitive salary package.

• Company car, fuel card, mobile subscription, laptop, and insurance package (group + hospitalization).

• Flexibility with hybrid working (onsite Antwerp + home office).

• Access to our competence centers for continuous learning and certifications.

• Involvement in long-term projects in stable enterprise environments.

• A collaborative culture where you can actively shape your career path.

What we offer to freelancers

• Long-term freelance missions in stable enterprise environments.

• Competitive daily rates aligned with market standards.

• Transparent and fast invoicing & payment processes.

• Opportunity to join Brainsquare competence centers and collaborate with peers.

• Option to engage in side assignments (assessments, pre-sales, training) with additional compensation.

• Close follow-up and support from Brainsquare as your partner.
