Job description

At ASI, our purpose is straightforward: we help people achieve great things through innovative solutions. Since 1991, we have built the iMIS® engagement management software that lets non‑profits, associations, and unions focus on their mission rather than their technology. Our founder‑led team of more than 300 people now serves over 4,000 clients across 28 countries, supporting more than 51 million users worldwide. Your work at ASI reaches further than you might expect.

We are guided by our three Core Values - Courage, Excellence, and Respect - and by a mission we hold to closely: keeping our clients for life. ASI is a genuine melting pot, a place where deep experience and fresh thinking sit side by side and sharpen one another. We offer the stability of a company with more than thirty years behind it and the momentum of one that is still growing and still innovating.

About the role

ASI is looking for a Senior .NET Software Developer: a creative and skilled engineer with a strong foundation in software performance and scalability. In this role you will build Microsoft-based software applications and products, with a particular focus on the performance and reliability of new software infrastructure. You will work exclusively within a .NET technology stack and partner closely with our software architects to deliver solutions that our clients can depend on.

What you will do

• Collaborate with software architects on product development and on the performance and reliability of new software infrastructure.
• Conduct code review, performance testing, and analysis across a range of software solutions, including legacy systems and microservices.
• Meet project milestones and complete architecture and enabler stories within sprints, as specified by the architectural runway.
• Work with the quality assurance team to integrate performance testing into the CI/CD pipeline, ensuring continuous performance validation.
• Follow established standards and guidelines to deliver work that is high in quality and value to ASI and its customers.
• Learn, follow, adapt, and apply SAFe Agile software principles.
• Receive, act on, and contribute to constructive feedback in support of continuous process, product, and self‑improvement.
• Work with Technical Support to reproduce and resolve customer issues as needed.
• Perform other job‑related duties and responsibilities as assigned.

What you will bring

• A bachelor’s degree in computer science, information science, or a related field, or equivalent experience.
• 8+ years of experience developing integrated suites of full‑featured web‑based applications, including user interfaces, database access, and networked components.
• Demonstrated knowledge of Microsoft tools and technologies: C#, .NET Core, .NET MVC, Entity Framework Core, SQL Server or Azure SQL, and Visual Studio.
• Experience with non‑Microsoft web application stacks, such as Java 8+, Spring and Hibernate, TypeScript, NodeJS, and Postgres or MySQL, may be considered in lieu of Microsoft technology experience. This role works exclusively with a .NET technology stack, with a focus on .NET Core.
• A solid object‑oriented analysis and design background, including automated unit and integration test writing, with proven experience implementing and testing high‑quality software.
• Experience benchmarking application page‑turn and API endpoint performance using JMeter, WAPT, or similar tools.
• Experience building and monitoring highly observable web applications using structured logging data, Azure Application Insights, and .NET Aspire.
• The ability to analyze legacy code based on MS Web Forms, Web Apps, and Web API, the MS .NET Framework, and AngularJS.
• Experience deploying and maintaining cloud‑based applications in a DevOps environment using Azure platform services, including Azure Application Insights, Azure App Service, Azure Containers, and Azure SQL, or similar.
• Experience implementing performance optimizations and tuning for legacy codebases and SQL schemas.
• Solid interpersonal skills and strong written and verbal communication.
• An excellent ability to collaborate with others, both in person and remotely.

What we offer

• Work that matters, supporting the organizations that serve communities, professions, and causes around the world.
• A modern technology stack built on Microsoft Azure, .NET, and SQL.
• A learning culture organized around continuous performance improvement, for our clients and for ourselves.
• The stability of a founder‑led company with more than thirty years of history, and genuine room to grow within it.
• A collaborative team that works well together both in person and remotely.
