This Senior Software Developer role covers designing, building, modernizing, and supporting enterprise applications on both modern and legacy stacks. The team wants a hands-on engineer who builds cloud-native applications and also maintains and gradually modernizes older systems, with strong design skills and the ability to mentor others.

Responsibilities

• Design and build scalable, secure, maintainable applications using C, modern.NET Core, REST APIs, React, microservices, and micro frontends.
• Turn business and product requirements into technical designs, APIs, services, components, data models, and integrations.
• Apply SOLID principles, clean architecture, separation of concerns, dependency injection, domain-driven design, and suitable design patterns.
• Set service boundaries that keep coupling low so teams can develop, test, deploy, and scale independently.
• Build, deploy, and run applications in the cloud using cloud-native services, containers, CI/CD, configuration management, logging, monitoring, and observability.
• Develop and integrate REST APIs, asynchronous messaging and events, and third-party systems.
• Work through iterative development and release cycles within Scrum.
• Work closely with product managers, tech leads, architects, QA, DevOps, application support, security, and other engineering teams in an Agile product model.
• Mentor junior and mid-level developers on design, coding standards, debugging, testing, AI-assisted development, and engineering practice, raising standards across the team.
• Investigate complex production issues, find root causes, and deliver lasting fixes and preventive measures.
• Write and maintain thorough technical documentation.
• Own assigned capabilities from technical design through development, testing, deployment, production validation, and ongoing support.

Requirements

• A bachelor's degree in computer science, information technology, or engineering, or equivalent experience.
• Typically 10+ years of professional software development, with substantial hands-on work building enterprise applications in C and.NET.
• Experience designing and building full-stack enterprise applications, not mainly maintaining existing ones.
• You can take a complex requirement from analysis and technical design through to implementation and production deployment on your own.
• Clear written and verbal communication, willingness to share knowledge, and good collaboration.
• Experience working in teams and with Agile methods is a must.
• Strong hands-on skill with C, modern.NET Core, ASP.NET Core, Web API, RESTful services, dependency injection, asynchronous programming, LINQ, Entity Framework or EF Core, and enterprise application development.
• Strong experience with React, JavaScript or TypeScript, HTML5, CSS, component-based development, state management, API integration, and modern frontend work. Experience with micro frontends is strongly preferred.
• Proven ability to apply SOLID principles, clean code, design patterns, layered or clean architecture, microservices, API-first design, event-driven concepts, domain modeling, resiliency patterns, and loosely coupled systems.
• Experience running applications in a public cloud, Azure preferred, including CI/CD pipelines, containers, cloud services, configuration, secrets management, monitoring, logging, and observability.
• Strong SQL, PL/SQL, and relational database skills, preferably SQL Server, including data access layers, integrations, APIs, messaging-based integrations, and efficient database access.
• A solid grasp of security practices, including authentication and authorization services.
• Strong experience with automated unit and integration testing, mocking, API testing, code quality, static analysis, secure coding, and automated quality gates.
• Ability to create, update, and improve stored procedures, SSRS reports, and SSIS packages.
• Effective use of generative AI and code-generation tools across the whole software lifecycle, not just for writing code, including requirement clarification, design, implementation, refactoring, test generation, debugging, documentation, and pull request and code review.
