INNOVATION. VALUES.

Our teams are made up of industry-leading experts who are passionate about doing great work and making a difference. We don’t just develop solutions, we support efforts that strengthen communities and serve the public good. \nRIVA’s culture is built on four core values: Results, Innovation, Values, and Accountability. They guide how we work, how we collaborate, and how we measure success. Our employee-first approach is rooted in trust, ownership, and meaningful work. By investing in our people and fostering a flexible, supportive environment, employees have the opportunity to grow their skills, contribute ideas, and make an impact from day one. all while supporting missions that matter. \nPOSITION OVERVIEW\nRIVA Solutions is hiring an Application Developer to maintain and extend the Manufacturing Extension Partnership Enterprise Information System (MEIS) for NIST MEP at the U.S. Department of Commerce. MEIS is two live C# applications running behind a single menu: a 15-year-old ASP.NET MVC application of roughly 200 pages, and a newer .NET Core application built in Blazor with Telerik components. Both run as containers on AWS EKS over one SQL Server database with several hundred SSRS reports, plus integrations to Salesforce and Dun & Bradstreet.\nYou will spend your week writing SQL data extracts, fixing and enhancing business modules, maintaining integrations, and working directly with federal users to turn vague problems into working software.\nCORE RESPONSIBILITIES\nMaintain and enhance both MEIS applications: the legacy ASP.NET MVC application and the newer .NET Core application in Blazor with Telerik UI components. The two run side by side behind a shared menu in a strangler- pattern migration, so you will work in both on the same day.\nWrite and tune SQL Server queries, views, and stored procedures to produce ad hoc data extracts. This is the single largest recurring demand on the team.\nBuild and maintain SSRS reports against an existing catalog of several hundred reports.\nPackage schema changes as DACPAC deliverables for the government database team to execute. Your own database access is read-only, so the packages have to be right the first time.\nMaintain the Salesforce integration, which maps each center's customized Salesforce data model to the MEIS datamodel using SOQL over Salesforce SOAP web services.\n\nMaintain the Dun & Bradstreet API integrations, including a cost-controlled manufacturer verification call and a bulk business metadata pull.\nMaintain the ServiceNow API integration that drives external user provisioning into Azure AD, covering roughly 2,000 guest accounts, and the custom-coded role-based authorization model that centers administer.\nLoad and transform annual reference data files, including Census County Business Patterns and ZIP to congressional district mappings, whose formats change between releases.\nSit with federal users who describe symptoms rather than requirements, elicit the real need, write the functional specification, then build it. This is a core part of the job, not an occasional extra.\nOwn your own testing. There are no dedicated testers and no automated test environment today.\nDeploy through GitLab CI/CD on a monthly release cadence with frequent out-of-band fixes, working Kanban with a two-week customer review.\nImprove technical documentation as you go. Documentation on the legacy application is thin.\nMINIMUM QUALIFICATIONS\nBachelor's degree in an information technology or related field from a accredited US University.\n8 or more years of professional software development experience.\nStrong C# across both .NET Framework and .NET Core.\nProduction experience with ASP.NET MVC.\nStrong SQL Server: complex queries, views, stored procedures, and performance tuning.\nSSRS report development.\nWeb service integration experience with both REST and SOAP.\nGit-based source control and CI/CD pipelines.\nDemonstrated ability to gather requirements directly from non-technical business users and write the specification yourself.\nU.S. citizenship. Must be able to pass a National Agency Check with Inquiries (NACI) background investigation and obtain an HSPD-12 badge, which typically takes 14 to 21 days.\nPREFERRED QUALIFICATIONS\nBlazor with Telerik UI components.\nLLBLGen Pro, or another commercial ORM such as NHibernate or Entity Framework.\nSalesforce SOQL and data model mapping between Salesforce and an external system.\nIntegration with commercial data APIs such as Dun & Bradstreet.\nContainerized .NET workloads running on AWS EKS.\nWindows scheduled services or background job processing.\njQuery and JavaScript maintenance in older web applications.\nSharePoint Online page and web part development.\nPrior federal experience, particularly on a program where a separate government team owns the infrastructure and the database\nThe salary or salary range for this role reflects an estimated range informed by multiple compensation factors. Final offers may vary based on considerations such as relevant experience, education and training, critical skillsets, and overall business needs.\nPay range\n$130,000—$145,000 USD\nEQUAL EMPLOYMENT OPPORTUNITY & ACCOMMODATION\nWe believe great teams are built from different backgrounds, perspectives, and lived experiences, and we mean that beyond the buzzwords. \nRIVA is an equal opportunity employer. We welcome applicants of every race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, veteran status, and any other characteristic protected by law.\nIf you need an accommodation at any point in our process, send an email to , we'll be happy to help.\nVETERAN SUPPORT & ACCESSIBILITY\nAs a federal contractor, RIVA follows the requirements of the Vietnam Era Veterans' Readjustment Assistance Act (VEVRAA) and Section 503 of the Rehabilitation Act, supporting the employment and advancement of protected veterans and individuals with disabilities. If you're a veteran, we encourage you to self-identify during the application process, it helps us track our hiring commitments and, in some cases, may support priority referral for open roles.\nRIVA also invites applicants to voluntarily self-identify as having a disability during the application process, not because it affects your chances of being hired, but because it helps us measure how well we're living up to our commitments and identify where we can do better.
