Our Engineering Standards

Balance Speed and Quality

Engineers are expected to balance delivery speed with a strong commitment to quality, meeting agreed timelines while producing reliable, maintainable, and well-tested solutions. Sound judgment in making trade-offs between velocity and long-term sustainability is essential.

Collaborate Effectively

Engineering is collaborative by default. Team members are expected to contribute constructively in design discussions, reviews, and planning, communicate clearly about progress and risks, and support shared team outcomes in both hybrid and distributed environments.

Build and Maintain Systems

Engineers are responsible for building new capabilities while maintaining and improving existing systems. This includes designing scalable solutions, reducing technical debt, supporting operational stability, and contributing to continuous improvement.

Operate with Autonomy

A high degree of autonomy is expected. Given clear objectives, engineers should independently translate problems into actionable technical approaches, proactively identify improvements, and continuously expand relevant technical expertise.

Ownership and Accountability

Ownership is fundamental. Engineers are accountable for the quality, performance, and customer impact of their work from design through post-release support, and are expected to follow through on commitments.

AI-Enabled Engineering

AI is reshaping how software is built, and we are committed to leveraging it as a force multiplier for creativity, impact, and capability. Engineers are expected to confidently apply strong technical fundamentals while embracing AI tools and approaches to enhance productivity, problem-solving, and innovation. Curiosity, adaptability, and enthusiasm for integrating AI into meaningful product development are essential.

Contribute to Team Culture

Engineers contribute positively to a culture of professionalism, transparency, low bureaucracy, and mutual respect, strengthening team performance through authenticity, curiosity, and collaboration.

About the Role

You’ll design and deliver scalable, high-impact solutions across our .NET and modern JavaScript stack. You’ll work on complex, real-world problems where performance, reliability, and maintainability matter. You’ll influence technical direction, elevate engineering standards, and help shape how we build as we scale.

AI is reshaping how software gets built — and we’re leaning in. We see AI as a force multiplier for strong engineers. If you’re excited to combine solid fundamentals with modern AI tooling to move faster and think bigger, you’ll thrive here.

What You’ll Own:

• Architecting and delivering scalable services using C#, .NET (Core, MVC, Web API), and SQL Server.
  
  
• Building modern, responsive applications using TypeScript and React (React Native a plus).
  
  
• Driving high engineering standards across testing, observability, performance, and security.
  
  
• Leading technical design discussions and influencing architectural decisions.
  
  
• Identifying and reducing technical debt while improving system resilience and scalability.
  
  
• Mentoring engineers and raising the overall capability of the team.

What Sets You Apart!

• 5-8+ years of professional software engineering experience, with significant experience delivering enterprise-grade systems.
  
  
• Strong expertise in C# and .NET (Core, MVC, Web API) within layered or service-oriented architectures.
  
  
• 3-5+ years working with SQL Server, including performance tuning, indexing strategies, query optimization, and data modeling for large datasets.
  
  
• Hands-on experience with Microsoft Azure, including services such as App Services, Azure Functions, Azure SQL, Service Bus, Storage Accounts, and Key Vault..
  
  
• Experience building and maintaining secure, compliant, enterprise-scale systems, including authentication/authorization (OAuth, OpenID Connect, Azure AD).
  
  
• Familiarity with microservices or modular monolith architectures in regulated or large organizational environments.
  
  
• Strong understanding of CI/CD pipelines (Github Actions preferred) and infrastructure-as-code practices such as ARM templates or Terraform.
  
  
• Experience implementing monitoring, logging, and observability using tools such as Datadog, Elastic, or Application Insights.
  
  
• Solid understanding of software architecture, scalability, and distributed system design within structured enterprise ecosystems.
  
  
• Experience collaborating across large, cross-functional teams with formal SDLC processes.

Our Core Technology Stack!

We build modern, scalable software on a thoughtfully designed stack:

• Frontend: TypeScript and JavaScript across Ember (today), React, and React Native.
• Backend: .NET / C# (Web API, .NET Core) powering distributed services.
• Data: SQL Server with performance and integrity at scale.
• Cloud: Microsoft Azure.
• Observability: Metrics, logging, alerting, and dashboards in Datadog — because we believe you can’t improve what you don’t measure.

Our architecture continues to evolve as we scale. We invest in event-driven systems, well-defined microservices, and containerized deployments (Azure Container Apps) to build resilient, decoupled, and high-performing software.

If you care about clean service boundaries, reliable systems, and shipping with confidence — you’ll feel right at home here.
