Software Engineer Ii

Software Engineer II / Mitikah We are seeking a Developer with good experience in .NET (C#/.NET 6+) for backend and BFF layers, jQuery for web front-end, and relational databases using the NHibernate ORM.This role will design, build, and maintain secure, scalable applications and services, exposing and consuming REST and SOAP integrations.You will work cross-functionally with Product, UX/UI, QA, and DevOps to accelerate delivery while upholding high engineering standards.The ideal candidate pairs architectural thinking with hands-on execution: writing clean, testable code; designing APIs; optimizing database access with NHibernate; automating tests; and communicating clearly.Success will be measured by the reliability of our services, the usability and performance of our web apps, and the speed and quality with which we ship value to production.What You'll Do Design and implement .NET microservices (C#/.NET 6/7/8) with ASP.NET Core, applying SOLID principles, design patterns, and clean code practices.Build and maintain ASP.NET Core Web APIs/BFFs for core backend services and service orchestration.Create web frontends with jQuery plus JavaScript/HTML/CSS , building reusable components and robust API integrations.Model and optimize data access with NHibernate (mapping, session/Unit of Work, caching, lazy/eager loading, transaction management, query tuning) over relational databases (e.g., SQL Server or PostgreSQL).Design, document, and version APIs — REST (OpenAPI/Swashbuckle) and SOAP (WSDL, XSD, WS-Security; WCF/CoreWCF)—ensuring compatibility and stability.Integrate with external systems via REST/SOAP, implementing OAuth2/OIDC/JWT, resilient error handling, retries/backoff, and observability.Ensure quality with unit, integration, contract, and end-to-end tests (xUnit/NUnit/MSTest; Playwright/Cypress; Postman/Insomnia/SoapUI for services).Set up and maintain CI/CD pipelines (GitHub Actions Pipelines) for build, test, static analysis, and automated deployments.Drive observability and reliability : structured logging, metrics, tracing (ELK/EFK, Datadog/Grafana), SLIs/SLOs, and alerting.Embed security by design : OWASP best practices, input validation, secret management, access controls, dependency hygiene, and hardening.Collaborate in agile workflows (Scrum/Kanban): backlog refinement, estimation, acceptance criteria, demos, and continuous improvement.Produce clear technical documentation (ADRs, C4 diagrams, runbooks) and participate in code reviews centered on readability, tests, and maintainability.Collaborate and help junior engineers and peers as needed and contribute to engineering culture and standards.Production operations and continuous reliability: Participate in on-call rotations; lead incident response (detection, containment, mitigation, and blameless postmortems); maintain proactive monitoring and alerting (SLIs/SLOs/SLAs); perform security hardening and patching; manage capacity and costs; and carry out preventive maintenance to minimize downtime.AI-assisted engineering and product features: Use AI coding assistants (e.g., GitHub Copilot/CodeWhisperer) to pair-program, generate tests, and speed up reviews while upholding code quality; design and integrate LLM-powered capabilities (search, summarization, chatbots) via APIs or hosted/on-prem models; coach teammates on effective, responsible AI workflows.What You'll Bring 2–4 years of professional full-stack experience with production delivery, scalability, and quality focus.Strong .NET (C#/.NET 6/7/8) skills with ASP.NET Core, microservice patterns, asynchronous programming, and familiarity with reactive/streaming paradigms.NHibernate expertise : fluent in mappings (attributes/XML/Fluent NHibernate), session/transaction management, second-level cache, query optimization; experience with relational databases (SQL Server or PostgreSQL).Experience with EF Core or Dapper is a plus.Frontend proficiency with jQuery plus JavaScript/HTML/CSS ; understanding of accessibility and web performance.API design WCF/CoreWCF); proficiency with Postman/SoapUI.Automated testing (xUnit/NUnit/MSTest; Playwright/Cypress), static analysis (SonarQube, Roslyn analyzers), and coverage practices.Desirable CI/CD Kubernetes and Terraform are desirable.Security : OWASP Top 10, OAuth2/OIDC, JWT, secret management, CORS policies, access control; basic compliance awareness (e.g., GDPR/ISO ***** is a plus).Observability : logs, metrics, traces; experience with ELK/EFK, DataDog/Grafana (preferred).Desirable Architecture : understanding of DDD, Clean Architecture, event-driven patterns, messaging (RabbitMQ/Kafka preferred), and caching (Redis).Soft skills : clear communication, critical thinking, autonomy, ownership, teamwork, and results orientation.Education : Bachelor's degree in Computer Science, Engineering, or related field (or equivalent experience).Cloud certifications (AWS/GCP/Azure) are a plus.Languages : Advanced Spanish; technical English for documentation and cross-team collaboration, #LI-MG1
