## Description

### Description

We’re seeking an experienced Software Engineer to maintain, enhance, and modernize a suite of .NET-based applications while developing new cross-platform, mobile, and distributed systems. This role bridges legacy modernization with next-generation engineering, spanning .NET, Flutter, Go, Docker, Linux, and private-cloud services.

A central component of this position involves integrating several independent internal applications to create a seamless, cohesive ecosystem across operational, logistics, compliance, and internal systems. The role also includes transforming a legacy Windows application into a modernized, forward-compatible software architecture.

The ideal candidate is comfortable working across Microsoft and non-Microsoft stacks, private cloud environments, Linux-based microservices, modern front-end development, and mobile applications. Familiarity with AI-assisted development tools (Cursor, Copilot, etc.) is highly valued to improve both speed and quality.

**Key Responsibilities**

-   Maintain, troubleshoot, refactor/modernize, and enhance existing .NET Framework / .NET Core applications.
-   Architect and develop APIs, microservices, event-driven components, and back-end systems for portals, dashboards, and enterprise workflows.
-   Build new back-end services using Go, .NET Core, Node.js, or Python for scalability and cross-platform compatibility.
-   Build cross-platform mobile and embedded applications using Flutter.
-   Develop lightweight, modern web interfaces using JavaScript/TypeScript with a strong focus on UX/UI design principles.
-   Integrate internal applications and data flows to improve cohesion across multiple sovereign systems, unifying workflows and reducing operational silos.
-   Plan and execute migration and modernization strategies to the organization’s private cloud environment.
-   Deploy and manage Linux-based services and containerized workloads (Docker).
-   Design and manage CI/CD deployments using Docker, GitHub Actions, or GitLab CI.
-   Manage relational databases (SQL Server, Postgres, MySQL), including schema design and performance tuning.
-   Utilize AI-assisted tools (Cursor AI, GitHub Copilot) to enforce quality and accelerate delivery.
-   Collaborate with IT, engineering, and operations teams to ensure seamless integration and interoperability across business systems.
-   Participate in Agile ceremonies, structured change workflows, code reviews, and automated testing.

## Requirements

**Required Qualifications**

-   3+ years of hands-on experience with .NET Framework / .NET Core development.
-   Experience building cross-platform mobile applications using Flutter (Dart).
-   Proficiency with Go or another compiled back-end language (Rust, Java, etc.).
-   Practical experience with Linux service deployment, CLI workflows, and diagnostics.
-   Solid understanding of Docker and containerization concepts.
-   Experience deploying applications into private cloud or on-premises virtualized environments.
-   Strong experience with SQL Server; additional experience with Postgres/MySQL is a plus.
-   Ability to support and modernize legacy on-premise applications while designing new cloud-hosted replacements.
-   Working knowledge of API design, REST, GraphQL, microservices, and distributed systems.
-   Hands-on experience with AI-assisted development tools.
-   Familiarity with Git, GitHub, Bitbucket, or Atlassian

**Preferred Skills**

-   Experience converting monolithic applications into microservice or container-based architectures.
-   CI/CD engineering with GitHub Actions, GitLab CI, or Jenkins.
-   Strong UX/UI fundamentals, wireframing, and component-driven design.
-   Familiarity with authentication systems (OAuth2, SAML, JWT).
-   Exposure to distributed logging and monitoring platforms such as Sentry.
-   Experience working with Atlassian tools (Jira, Confluence) and formal change-order or ticket-based development workflows (helpful but not require)
-   Background in logistics, ERP, or enterprise operational platforms is a strong plus.

**Soft Skills**

-   Excellent communication and cross-team collaboration abilities.
-   Strong analytical and problem-solving mindset.
-   Adaptable, self-directed, and eager to adopt new technologies.
-   Strong sense of ownership, accountability, and architectural quality.
-   Passionate about automation, UX/UI consistency, performance, and clean engineering principles.
