Software Engineer (Cloud, Cross-Platform & .NET Systems)

Al Warren Oil Company Inc.
Bensenville, IL

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.

Benefits

  • 401(K) with company match from Day 1
  • Blue Cross Blue Shield health insurance – medical, dental, vision, prescription
  • Paid vacation, holidays, and personal time
  • Optional life and disability insurance
  • Safety bonuses for clean roadside inspections and safe driving records
  • Paid training, PPE, and late-model, well-maintained trucks
  • Boot reimbursement program
  • Up to $2,400 company contribution to Health Savings Account (HSA)
