We are working against objectives, milestones not against tickets. We welcome any ideas, innovations and celebrate self-driven activities improving our solutions.<\/p>\n<h4>The Mission<\/h4>\n<p>Our platform is entering a major architectural evolution. We are redesigning significant parts of the backend and gradually moving toward a more event-driven architecture.<\/p>\n<p>This transition will involve working on:<\/p>\n<ul>\n<li>distributed workflows<\/li>\n<li>eventual consistency<\/li>\n<li>asynchronous processing<\/li>\n<li>service decoupling<\/li>\n<li>data integrity across services<\/li>\n<li>performance and database optimization<\/li>\n<\/ul>\n<p>The work ahead is complex and challenging, but also a great opportunity to shape the system architecture and grow technically.<\/p>\n<p>We are currently hiring multiple, backend engineers who want to contribute to this journey.<\/p>\n<h4>What You Will Work On<\/h4>\n<p>You will design and implement backend services that power our platform, including:<\/p>\n<ul>\n<li>REST APIs built with .NET<\/li>\n<li>Decoupled, asynchronous background services<\/li>\n<li>Distributed workflows<\/li>\n<li>Event-driven system components<\/li>\n<li>Cloud-native services running on AWS (mostly)<\/li>\n<\/ul>\n<p>This is not purely an implementation role. You are expected to participate in architecture discussions, design decisions, and system evolution.<\/p>\n<h4>Must-Have Skills<\/h4>\n<ul>\n<li>Strong experience with C# and .NET<\/li>\n<li>Experience building ASP.NET web applications<\/li>\n<li>Experience with asynchronous programming<\/li>\n<li>Experience designing maintainable backend architectures<\/li>\n<li>Experience implementing background services \/ job processing<\/li>\n<li>Ability to reason about system behavior, edge cases, and failure scenarios<\/li>\n<\/ul>\n<h4>Highly Preferred<\/h4>\n<ul>\n<li>Working experience with AI assistants (CoPilot, Codex, Claude, etc.)<\/li>\n<li>Strong SQL knowledge<\/li>\n<li>raw SQL queries<\/li>\n<li>stored procedures<\/li>\n<li>transaction handling<\/li>\n<li>isolation levels<\/li>\n<li>indexing and performance optimization<\/li>\n<li>Experience using Dapper and\/or Entity Framework<\/li>\n<li>Experience designing or working with event-driven systems<\/li>\n<\/ul>\n<h4>Nice-to-Have<\/h4>\n<ul>\n<li>Angular \/ TypeScript familiarity<\/li>\n<li>Experience using REST API tools (Postman, Insomnia, etc.)<\/li>\n<li>Experience with AWS cloud services (Cognito, S3, ECS \/ EC2, Lambda, Bedrock)<\/li>\n<li>Interest or experience with AI-related services such as AWS Bedrock<\/li>\n<li>Hands on experience with Agentic solutions<\/li>\n<\/ul>\n<h4>What Kind of Engineer Thrives Here<\/h4>\n<h5><strong>We value engineers who:<\/strong><\/h5>\n<ul>\n<li>are self-driven and proactive<\/li>\n<li>are comfortable challenging the status quo<\/li>\n<li>propose conceptual and architectural improvements<\/li>\n<li>communicate clearly and confidently<\/li>\n<li>can explain technical decisions and trade-offs<\/li>\n<li>are comfortable interacting with technical leadership or management<\/li>\n<li>can push back on unrealistic timelines or risky design choices<\/li>\n<\/ul>\n<p>Strong communication and reasoning skills are just as important as coding ability.<\/p>\n<h4>Why This Role Is Interesting<\/h4>\n<h5><strong>You will have the opportunity to:<\/strong><\/h5>\n<ul>\n<li>contribute to a major backend architecture redesign<\/li>\n<li>work with event-driven systems<\/li>\n<li>influence technical decisions<\/li>\n<li>build systems in AWS cloud infrastructure<\/li>\n<li>tackle complex engineering problems<\/li>\n<li>learn deeply about distributed system design<\/li>\n<\/ul>\n<p>If you enjoy understanding systems deeply,
