Archers Product Lifecycle Engineering (PLE) team builds and runs the engineering systems that help define Archer products. As Senior Staff Software Engineer Full Stack you will own one or more of Archers internally developed engineering applications: systems of record that engineering teams rely on to manage critical configuration-controlled technical data across product releases. You will develop the application run it as a production service and support the engineers across several disciplines who depend on it every day.

• Develop maintain and extend one or more C#/.NET ( Core) Blazor web applications with a layered Domain/Application/Infrastructure architecture and a schema-driven data model
• Own the full development lifecycle - feature development bug fixes code review testing release and technical documentation
• Build and maintain importers and exporters for data including SysML (Cameo) model ingestion CAN DBC import and ICD report generation
• Administer your applications as production services: deployment monitoring backups upgrades user access and protected-branch policies
• Own the CI/CD pipeline and the applications Git-based configuration control model: branching tagging merges and release/hotfix workflows
• Create/maintain integrations with other enterprise tools such as Jira Cameo Polarion and coordinate ICD data flow from the MBSE model to downstream avionics software hardware and integration test consumers
• Triage and resolve user-reported issues and data-integrity problems with heightened availability around ICD release and hotfix windows
• Partner with Systems Engineering to translate ICD change requests into correct traceable tool updates
• Produce user documentation release notes training and operational runbooks for the user community

• Bachelors degree in Computer Science Software Engineering or a related field.
• 5 years of professional software engineering experience including production-grade C#/.NET ( Core) development
• Experience with Blazor or a comparable modern component-based web UI framework
• Comfort working in a layered / Domain-Driven Design architecture and evolving a schema-driven domain model
• Solid Python scripting for data import processing and automation
• Hands-on experience with Docker-based build and deployment
• Deep Git proficiency: branching merging tagging protected branches pull-request and release workflows (Bitbucket)
• Experience maintaining and troubleshooting CI/CD pipelines (Bitbucket Pipelines and/or TeamCity)
• Ability to independently own a mission-critical internal application from feature development through production operations and to communicate clearly with a technical engineering user base
• Hands-on experience using Claude Code (or comparable AI coding agents) to generate refactor test and document production code.

• Working knowledge of avionics data buses (ARINC 429 ARINC 664/AFDX ARINC 717 CAN RS-422 analog discrete) and Interface Control Document concepts
• Aerospace or regulated-industry experience including configuration management and change-control discipline
• Experience with MBSE/SysML tooling (Cameo) and model-based interface definitions
• JSON/structured schema design and validation for interface data
• Experience building plugin/extension architectures or application authentication/SSO integration
• Comfort with AI-assisted development workflows
