About The Position

We are seeking a full-time Senior Full-Stack Software Engineer to lead the technical design, development, and ongoing support of an internal manufacturing and operations platform. The platform will support supply chain, inventory, purchasing, material planning, production execution, and traceability. The role involves evaluating an existing codebase, improving established software, and designing new systems. It is a hands-on senior engineering position requiring experience delivering and maintaining production business applications. The engineer will work closely with the Supply Chain & Operations Software Manager, who identifies operational needs and establishes priorities. The engineer will own technical implementation, communicate tradeoffs, and deliver reliable software in manageable phases. The engineer will partner with business users to understand workflows and translate operational needs into maintainable software; assess the existing B4Bridge application, available licensed source code, database structure, and integrations; and design, develop, test, and maintain frontend interfaces, backend services, APIs, and relational databases. The engineer may extend and refactor the existing licensed application or establish the architecture and foundation for a new platform. The platform will provide capabilities for product and part records, bills of materials, revision control, purchasing, receiving, inventory, material allocation, work orders, production reporting, serial and lot traceability, material consumption, quality status, and auditable transaction history. The role also involves protecting data integrity; building interfaces and dashboards for office and shop-floor users; integrating approved business systems; supporting data migration and reconciliation; implementing security and approval workflows; establishing automated tests and deployment pipelines; and maintaining releases, production support, monitoring, performance, and technical documentation. The engineer will work with IT and security personnel to deploy and support the platform in approved environments and must use approved development tools and protect proprietary, sensitive, and export-controlled information. Employment is contingent on the ability to obtain and maintain a U.S. government Secret-level security clearance. Applicants must be U.S. citizens and willing to complete the required background investigation and government adjudication process. An active clearance is not required at application time; clearance eligibility is determined solely by the U.S. government. Baxter Aerospace develops satellite communication equipment used for critical missions, including aerial firefighting, aircraft camera data transmission, and deployed team coordination. The company describes its environment as collaborative and fast-paced, with an emphasis on innovation, precision, and quality.
