We are seeking a Software Developer/Engineer with strong cloud engineering (Azure) experience, modern CI/CD practices, and advanced React UI development expertise to design, build, and support enterprise web applications and digital interfaces used across manufacturing and business operations.

This role is ideal for a hands-on engineer who can balance architecture and delivery, improve reliability and security, and mentor others while partnering with cross-functional stakeholders.

RESPONSIBILITIES

• Design, develop, and maintain enterprise-level web applications and APIs using Microsoft .NET technologies (C#, ASP.NET Core, RESTful services).
• Architect and implement modern, responsive, user-centric web interfaces using React (preferably with TypeScript), along with HTML/CSS and modern UI frameworks.
• Lead or significantly contribute to cloud application architecture (Azure preferred; AWS acceptable), including:
• Deployment patterns (App Services, containers, Kubernetes, serverless)
• Secure networking and identity/integrations
• Performance, scalability, high availability, and disaster recovery considerations
• Build and maintain robust CI/CD pipelines (Azure DevOps, GitHub Actions, or similar), including:
• Automated builds, tests, linting, packaging, and deployments
• Environment promotion strategies (dev/test/stage/prod)
• Release governance and rollback strategies
• Implement and maintain Infrastructure as Code (IaC) practices (e.g., Bicep/ARM, Terraform, or equivalent).
• Develop secure back-end services and integrations for ERP/manufacturing systems (SQL Server, APIs, data flows, authentication/authorization).
• Create and maintain technical documentation aligned to SDLC expectations (requirements, design specs, interface specs, test/validation procedures, release notes).
• Collaborate with internal teams (Operations, Manufacturing, Quality, Engineering, IT) to gather requirements, plan releases, and deliver enhancements with minimal disruption.
• Ensure adherence to security best practices (secure coding, access control, secrets management, data protection) and support vulnerability remediation efforts.
• Improve observability and maintainability by implementing logging/monitoring and performance diagnostics (e.g., Application Insights, cloud monitoring tools, structured logging).
• Participate in production support and issue resolution, including root cause analysis and preventative improvements.
• Mentor and guide junior developers through code reviews, best practices, and technical decision-making.
• QUALIFICATIONS
• Bachelor’s degree in computer science, Computer Engineering, MIS, or a related technical discipline (or equivalent professional experience).
• 5 years of professional experience building and supporting web applications (full-stack or strong front-end back-end collaboration).
• Advanced proficiency with:
• C# / .NET / ASP.NET Core
• SQL Server (querying, performance tuning fundamentals, stored procedures as applicable)
• React (strong UI engineering skills, TypeScript highly preferred)
• Git workflows (branching strategies, pull requests, code review practices)
• Demonstrated experience delivering solutions in a cloud environment (Azure/AWS), including application deployment and operational considerations.
• Hands-on experience implementing and maintaining CI/CD pipelines.
• Strong understanding of secure software development practices, including authentication/authorization patterns and secure API design.
• Ability to work in a manufacturing/enterprise environment with cross-functional stakeholders and production deadlines.
• Strong problem-solving skills, communication skills, and a track record of delivering reliable software.

Preferred Qualifications (Nice to Have)

• Experience with Azure services (App Service, Functions, AKS/Kubernetes, Key Vault, Storage, Service Bus, SQL Azure) or equivalent AWS services.
• Experience with containerization (Docker) and orchestration (Kubernetes).
• Experience with automated testing (unit/integration/UI), quality gates, and policy-as-code.
• Experience with ERP/MES ecosystems (any major ERP; manufacturing integration experience strongly preferred).
• Reporting and analytics experience (e.g., SSRS, Power BI, or modern embedded analytics patterns).
• Familiarity with OWASP guidance and secure development tooling (SAST/DAST, dependency scanning, secret scanning).
