About the Role

We’re looking for a Senior Software Engineer who enjoys building scalable, high-quality software and influencing how products are designed and delivered.

This role is ideal for someone who thrives in a collaborative environment, likes solving complex problems, and wants to help shape engineering standards while mentoring other developers.

What You’ll Do

• Design, build, and evolve modern web applications and services using .NET and contemporary front-end frameworks.
• Lead technical design decisions and contribute to architecture for complex, business-critical systems.
• Own features end-to-end—from requirements and estimation through development, testing, and deployment.
• Provide technical leadership and mentorship to engineers across the team.
• Write clean, maintainable, well-tested code and continuously look for ways to improve performance and scalability.
• Partner closely with Product and cross-functional teams to align technical solutions with business goals.
• Support production releases and serve as a technical point of contact during deployments.
• Troubleshoot and resolve production issues, participating in an on-call rotation as needed.
• Advocate for modern engineering practices, tools, and technologies that improve quality and developer experience.

• Experience designing and working within distributed systems and service‑oriented architectures.

Technical Skills

• Strong expertise in C# and the .NET ecosystem (.NET Framework 4.5+ / .NET Core).
• Solid understanding of object-oriented design and software architecture principles.
• Experience with relational databases, advanced SQL, and performance optimization.
• Web application development and API design/integration.
• Asynchronous communication technologies (e.g., SignalR).
• Message-based systems such as RabbitMQ.
• Proficiency with Git and modern development workflows.

How You Work

• You take ownership and are comfortable driving work forward with minimal direction.
• You’re curious, adaptable, and enjoy learning new technologies.
• You communicate clearly and collaborate well with both technical and non-technical partners.
• You’re organized, pragmatic, and balance quality with delivery.
• You’re comfortable working in a remote or hybrid environment.

Education

• Bachelor’s degree in Computer Science, Information Technology, or a related field preferred.
• Equivalent professional experience will be considered in place of a degree.
