The interview process at Archer is comprehensive, rigorous, and designed to evaluate both theoretical engineering knowledge and practical execution capabilities. Given the multidisciplinary nature of eVTOL aircraft development, candidates interface with recruiters, hiring managers, cross-functional engineers, and technical directors throughout the pipeline.

The hiring workflow typically starts with a standard recruiter conversation followed by a technical screen with the hiring manager or a senior engineer. Candidates who advance are invited to a comprehensive final round, which frequently includes an intensive case study presentation. For this stage, you are given an open-ended technical prompt or architecture exercise several days in advance, which you present to a panel of senior engineers and leadership, followed by dedicated 1-on-1 deep dives.

The timeline above illustrates the typical progression from initial application through final evaluation stages. Candidates should expect a process that balances speed with technical depth, often wrapping up within three to six weeks. The case study presentation is the core differentiator in Archer's evaluation process, requiring you to showcase clear architectural decision-making and strong verbal communication.

System Architecture & Testing Pipelines

This evaluation area assesses your ability to design robust software systems, define clear operational interfaces, and build automated verification frameworks. Safety-critical environments require strict traceability from initial change requests down to build artifacts and hardware-in-the-loop (HITL) tests.
