• Build & Iterate: Design, develop, and maintain high-quality back-end services, RESTful/GraphQL APIs, and microservices using .NET. • Storage: Work with relational databases (primarily SQL Server) – design schemas, write efficient queries, and optimise performance. • Data Access: Implement data access layers using Entity Framework Core. • Auth: Build and integrate authentication & authorisation mechanisms. • Collaborate: Work within a loose Agile/Sprint framework, contributing to storyboarding and regular sprint planning meetings, and work closely with front-end developers, QA engineers, and product owners to deliver end-to-end features. • Code Quality: Implement clean, maintainable, and automated code testing following Clean Architecture principles and current best practices. • Performance: Identity and resolve performance bottlenecks, security issues, and production incidents. • Documentation: Help maintain technical documentation for APIs and services (Swagger / OpenAPI).

• Design, deploy, and manage Kubernetes-based containerized application environments • Configure and maintain Kubernetes clusters in cloud-native infrastructures • Support container networking, orchestration, and cluster scalability • Deploy and manage applications using Helm charts • Automate CI/CD pipelines for application deployment and system integration • Monitor and maintain Kubernetes platform health, performance, and availability • Implement Kubernetes security best practices and access controls • Utilize monitoring and logging tools such as Prometheus, Grafana, and ELK stack • Troubleshoot containerized applications, cluster performance, and networking issues • Implement and support service mesh architectures such as Istio or Linkerd • Support Infrastructure as Code (IaC) automation using Terraform or Ansible • Collaborate with development, cloud, and DevOps teams to optimize deployments and operations

• As a Software Developer, you are a leader by example, you are a subject matter expert, and you help lead strategic technical direction. • You will get to interact with key client stakeholders on a regular basis and use your experience to prove business ROI through innovative greenfield technology solutions. • Software Developers typically have longer tenures and higher retention rates with Callibrity than other companies because the work is challenging and rewarding, we have a strong engineering culture, and we invest in the best people. • Callibrity Software Developers can solve a broad subset of problems with a broader set of solutions by choosing the right language, framework, and tool for a problem. • Work directly with key stakeholders at our clients to accomplish shared goals. • Communicate complex ideas effectively, both verbally and in writing. • Proactively identify opportunities, challenges, and issues and recommend a solution. • Demonstrate mastery of software development best practices (Agile, DevOps, Test Automation, CI/CD, TDD). • Stay ahead of the curve by exploring new technologies including AI, Machine Learning, Cloud, and IoT. • Thrive in an environment where there is close interaction among different roles and teams. • Are admired by the client as someone they can count on, regardless of title or seniority.

• Absorber rápidamente el contexto del proyecto y el levantamiento de requerimientos previo, asegurando una total alineación con el equipo actual y los objetivos técnicos ya trazados. • Diseñar, programar y avanzar en la migración de soluciones, conectando de manera eficiente la lógica de negocio en C#/.NET con los componentes de frontend en React.js que ya están definidos o en proceso de construcción. • Ejecutar la transición de los portales tradicionales hacia la nueva infraestructura, asegurando el rendimiento de las consultas en SQL Server y minimizando el impacto en la operación actual. • Mantener y elevar el estándar del código, aplicando buenas prácticas de desarrollo para garantizar que las nuevas plataformas sean mantenibles, seguras y preparadas para el futuro (aprovechando Azure cuando corresponda).
