Our software runs in production across more than two dozen jurisdictions in the United States and Canada, where reliability and auditability are contractual obligations rather than aspirations.\nWe are seeking a Senior Software Engineer to design, build and maintain data-intensive enterprise applications across that portfolio. The majority of this work is in C# and .NET, backed by SQL Server. Our front ends vary: some applications are built entirely in Vue.js, one of our primary applications uses Vue selectively, and another uses none at all - so you will move between modern component-based front ends and traditional server-rendered views. Some of our highest-throughput components are written in C++, so working proficiency there - or the appetite to develop it - matters, but .NET is where most of your time will be spent.\nSuccess requires strong problem-solving skills, comfort moving across mixed technology stacks, and genuine ownership of delivering reliable solutions in real production environments. You will work in systems that carry years of accumulated business logic, and you will help modernize them without disrupting the jurisdictions that rely on them daily.\nDuties and Responsibilities:\nDesign, build and support web applications and services using C# and .NET MVC\nDesign and optimize SQL Server queries and data access patterns for high-performance transactional systems, with emphasis on query efficiency, indexing strategy and minimizing latency\nContribute to front-end development across a mixed estate - Vue.js applications, partial Vue adoption, and traditional server-rendered views\nMaintain and extend core application logic in C++ where our highest-throughput components require it\nTroubleshoot and resolve complex production issues spanning database, backend and UI layers\nWork within and improve complex legacy systems while maintaining production stability\nContribute to ongoing modernization efforts across legacy and current platforms\nDeliver jurisdiction-specific change requests and configuration work to committed dates\nCollaborate with QA, Product and cross-functional teams to deliver high-quality releases\nParticipate in code reviews and help raise development standards\nSupport automated testing and CI/CD pipeline improvements\nMentor engineers and contribute to the technical growth of the team\nEducation and Experience:\nStrong professional experience with C# and .NET, building and maintaining production web applications and services\nStrong experience with SQL Server, including query design and optimization, performance tuning and efficient data access patterns\nStrong object-oriented design skills, with a working commitment to SOLID principles and the judgment to apply them pragmatically in existing code\nExperience with systems where performance and reliability are critical to business operations\nWorking proficiency in C++, sufficient to read, debug and modify existing production code, with the willingness to deepen it. We do not expect a C++ specialist, but you will encounter it.\nExperience with modern front-end frameworks such as Vue.js, or the ability to pick one up quickly, alongside comfort working in traditional server-rendered front ends\n5-8 years of professional software development experience\nExperience conducting code reviews and mentoring other engineers\nExperience in complex, multi-system or legacy-integrated environments\nExperience with modern AI-assisted development tools such as Claude Code, Cursor or GitHub Copilot\nExperience modernizing legacy systems or working in hybrid environments\nExperience with mobile development frameworks such as React Native\nExperience with UWP\nExperience in regulated or compliance-driven environments, for example PCI\nExperience working with government or public-sector customers\nExperience with CI/CD pipelines, including building and maintaining automated build and release workflows\nAzure cloud development experience, including cloud architecture and deploying and operating services in Azure\nDeeper C++ experience in production systems\n\nKnowledge, Skills and Abilities:\nAbility to debug complex issues across multiple layers - database, backend and UI\nProven ability to design and implement maintainable, scalable systems\nStrong collaboration across engineering, QA and product teams\nAbility to take ownership of deliverables and drive work to completion\nAbility to understand existing systems quickly and make safe, incremental improvements in production\nWe are looking for an object-oriented developer in the fullest sense: someone who designs with SOLID principles in mind and writes code that others can safely change.\nDemonstrated understanding of reliability, scalability, security and maintainability, and the judgment to know which matters most in a given change.\nWorking knowledge of OWASP secure coding practices\n\nWork Environment\nOffice setting with a moderate noise level.\nThe employee will work at an individual workstation, using a telephone and computer.\n\nPhysical Demands\nMust be able to remain seated for extended periods.\nRegular use of a computer and other office machinery, such as printers and copy machines.\nOccasional movement around the office.\nFrequent communication via telephone.\n\nNeumo Summary\nWith the backing of four decades of public sector expertise and corporate capability, Neumo has successfully supported government services.
