Job title: Senior .NET Developer

Job type: Contract

Contract Length: 6 months contract to hire 

Rate: $60 - $80 per hour 

Role Location: United States 

We’re looking for an experienced Senior Software Engineer to join our growing team — someone who loves tackling complex challenges, mentoring others, and delivering high-quality, production-ready software.

In this role, you’ll work as part of a cross-functional, DevOps-driven Agile team covering the full development lifecycle — from concept to deployment and continuous improvement. You’ll collaborate closely with product managers, architects, designers, and engineers to deliver solutions that are as elegant as they are effective.

Role and Responsibilities:
 

  • Lead and contribute to the design and development of modern software solutions across the stack.

  • Collaborate with architects, engineers, designers, and product managers to deliver high-impact products.

  • Drive discussions around technical design and architecture, ensuring scalability, security, and reliability.

  • Write clean, maintainable code and documentation using best practices and design patterns.

  • Coach and mentor other engineers, fostering a culture of quality and continuous learning.

  • Build and maintain APIs, services, and microservices that power next-gen user experiences.

  • Apply Test-First and Acceptance Criteria–driven approaches to ensure robust, high-quality releases.

  • Stay current on emerging tools, frameworks, and practices, and bring fresh thinking to the team.

Job Requirements:

  • 5–10 years of hands-on software product development experience.

  • Strong skills in .NET 6+, C# 10+, React (16+), Redux, TypeScript, and databases such as SQL Server and MongoDB.

  • Solid experience with cloud environments (Azure preferred) and infrastructure-as-code principles.

  • Proficiency with containers (Docker) and Kubernetes for deployment and orchestration.

  • Deep understanding of microservices, API design, and event-driven architectures.

  • Familiarity with Git, CI/CD pipelines, automated testing, and Agile methodologies (Scrum, Kanban, XP).

  • Knowledge of secure coding practices, compliance standards (GDPR, PCI-DSS, ISO 27001), and performance optimization.

  • A proactive, collaborative attitude and strong communication skills — you enjoy working closely with others to get things done.
