Job summary

Archer is seeking a Senior Staff Software Engineer, Full Stack, to own and evolve internal engineering apps that manage critical MBSE data and product configurations. You will develop, deploy, monitor, and document production services, collaborating across engineering disciplines.

You will build data import/export tools (SysML/Cameo, CAN DBC, ICD reports), manage CI/CD pipelines, and implement integrations with Jira, Cameo, and Polarion, while ensuring high availability and clear user

Qualifications

• Bachelor's degree in Computer Science, Software Engineering, or a related field.
• 5+ years of professional software engineering experience, including production-grade C#/.NET (ASP.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.

Responsibilities

• Develop, maintain, and extend one or more C#/.NET (ASP.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 application's 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.
