Senior Staff Applications Engineer

Headquartered in Silicon Valley, California, Archer is a leader in the next-gen aerospace sector building an end-to-end advanced air mobility platform that delivers air taxis, unmanned aircraft systems (“UAS”), aviation-related physical artificial intelligence (“AI”) solutions, and other technologies to customers worldwide across the commercial aerospace and defense sectors.

Our sights are set high and our problems are hard, and we believe that diversity in the workplace is what makes us smarter, drives better insights, and will ultimately lift us all to success. We are dedicated to cultivating an equitable and inclusive environment that embraces our differences, and supports and celebrates all of our team members.

About the Role

Archer's 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 Archer's 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.

What You'll Do:

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

What You Need:

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.

Bonus Qualifications:

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
