Software Engineer, Enterprise Systems

General Matter, Inc. is an American nuclear energy company based in California that is focused on developing domestic nuclear energy solutions. The company aims to harness nuclear technology to increase national energy prosperity, reduce dependence on foreign energy sources, and support the expansion of American capabilities in the energy sector. Their work centers on making nuclear energy more accessible and practical by advancing technologies that can be developed and deployed within the United States. General Matter's mission is rooted in the belief that nuclear power represents a critical pathway toward a cleaner, more energy-independent future. By turning domestic nuclear potential into operational reality, the company positions itself at the intersection of national security, economic growth, and climate-conscious energy production. Their approach emphasizes building nuclear energy infrastructure that is homegrown rather than reliant on foreign supply chains or expertise. The company brings together leaders from nuclear engineering, technology, government, and finance, reflecting a multidisciplinary approach to solving the complex challenges of modern nuclear energy development. As a startup operating in the green and climate technology sector, General Matter represents a new wave of private investment in nuclear energy as a viable and scalable low-carbon power source for the United States.

About the Company

General Matter is enriching uranium in America. 

Our goal is to design, build, and operate the world’s lowest-cost enrichment services in the United States.  

Our mission is to restore America’s ability to produce nuclear fuel—fuel that will power AI, advanced manufacturing, critical industries, and the next generation of nuclear reactors. 

Ultimately, our work will help power national ambitions and enable a high-energy society. 

We were incubated by Founders Fund, like Anduril and Palantir before us, and are backed by top-tier investors. Our lean, world-class team of engineers and operators is applying a first-principles approach to solving the problem of nuclear fuel production.  

We are a mission-driven company with a culture of urgency, accountability, and transparency. 

Help us build a high-energy society by making the cleanest, safest form of baseload energy the most affordable. 

About This Role

 

As a Software Engineer, Enterprise Systems, you will build and own the integrations that connect our engineering, manufacturing, and business systems.

Your first project is the PLM/PDM-to-MES pipeline that moves released parts, bills of materials, and engineering data into manufacturing. You will own this integration end to end, from API and data mapping through production monitoring and troubleshooting, and then expand into integrations across our MES, WMS, QMS, and ERP systems as the company scales.

This is a hands on software engineering role. You will write production code in C#/.NET, work directly with REST APIs and enterprise platforms, and build the infrastructure needed to move data reliably across the organization.

 

Responsibilities 

• Build, own, and operate integrations across the manufacturing and business landscape (MES, WMS, QMS, PLM/PDM, ERP, and, over time, CRM and HRIS) as the systems grow. 
• Own and extend the PLM/PDM-to-MES pipeline, including released-part master data, bills of materials, and engineering files, as the program's first integration. 
• Develop and maintain API integrations, custom services, and add-ins in C#/.NET against platform REST APIs, including notification and alerting workflows. 
• Extend and customize platforms directly through their native tools, such as server-side scripting, query languages, workflow automation, and custom objects, when out-of-the-box configuration is not enough. 
• Build production-grade monitoring, logging, retry, reconciliation, and exception handling, and keep data mappings, interface specifications, and source-to-target documentation current. 
• Enforce the controlled-versus-uncontrolled data boundary and partner with Security and IT on authentication, authorization, encryption, secrets management, and access control, with CI/CD and version control throughout. 
• Own data migration as systems move to implementation, including extraction, mapping, cleansing, validation, and cutover, and drive integration failures and data discrepancies to root cause. 

Basic Qualifications 

• Experience with systems integration, software development, or enterprise or manufacturing systems engineering. 
• Hands-on experience building and supporting production integrations using REST APIs, SDKs, and custom services. 
• Strong software development experience in C#/.NET, or strong proficiency in a comparable language such as Python, Java, or C++ with the ability to work in C#/.NET. 
• Solid grasp of APIs, data mapping, and integration patterns, including authentication, error handling, retries, and reconciliation, with strong SQL and data-modeling fundamentals. 
• Experience with source control and CI/CD, such as Git and modern pipelines, and disciplined release practices. 
• Bachelor's degree in Computer Science, Engineering, Information Systems, Data Science, or a related field, or equivalent experience. 

Preferred Skills and Experience 

• Hands-on customization of enterprise ERP platforms using their native development tools, including application languages, built-in query languages, and workflow builders. Experience with major ERP platforms such as SAP or Oracle is a plus. 
• Extending CRM platforms through their native programming language and component-based UI framework, along with their query languages and declarative automation. 
• Automating or integrating CAD, PDM, or PLM tools through their scripting interfaces and COM or .NET APIs. 
• Integrating or administering manufacturing execution (MES), quality (QMS), or warehouse (WMS) platforms, including cloud MES REST APIs. 
• Experience with integration platforms (iPaaS) and middleware, such as MuleSoft, Boomi, or Workato, and with event-driven patterns, webhooks, and message queues. 
• Proficiency in JavaScript or TypeScript and Python alongside C#/.NET, and comfort picking up the proprietary scripting and query languages that enterprise platforms expose. 
• Familiarity with engineering data formats and transmittals, such as STEP files, drawings, and bill-of-materials structures, and with label-printing or barcode systems. 
• Experience with cloud data warehouses, such as Snowflake, BigQuery, Redshift, or Databricks, and migrating data across enterprise systems, including from legacy finance systems. 
• Experience in regulated industries, such as aerospace, defense, energy, medical device, automotive, or nuclear, and familiarity with governance and compliance frameworks, such as SOX, SOC 2, ISO 27001, NIST, or NQA-1. 
• Experience with cloud services, such as AWS (including GovCloud), Azure, or Google Cloud. 

Additional Requirements 

• Based in Los Angeles, CA, and onsite full-time. Hybrid and remote arrangements will not be considered.
