Job Description:

Archer is an aerospace company based in San Jose, California building an all-electric vertical takeoff and landing aircraft with a mission to advance the benefits of sustainable air mobility. We are designing, manufacturing, and operating an all-electric aircraft that can carry four passengers while producing minimal noise. 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. What You’ll Do: In the Battery Controls Integration Engineer role, you will be responsible for integrating Archer’s high voltage battery controls system onto test platforms and verifying BMS safety-critical functionality – enabling the use of electric vertical-takeoff-and-landing aircraft for urban air mobility. Your deliverables will span all phases of the product development life cycle: development, implementation, validation, and continuous improvement. Specifically, you will… Core Responsibilities and Development Focus Verification and Testing Strategy: Develop and execute verification procedures and test plans across various environments: Simulation, Software-in-the-Loop (SIL), Hardware-in-the-Loop (HIL). Integrated Testing Ownership : Own the Battery Management System (BMS) controls hardware/software integrated system functionality testing on safety-critical components, utilizing HIL, SIL, and high-voltage (HV) integrated labs. Automation and Infrastructure: Implement updates to automated test cases in synchronization with BMS functionality development for verification and regression testing, specifically using model-based environments. Test System Development : Provide commissioning and maintenance support for the complete testing infrastructure required to enable HIL testing of BMS controls, algorithms, and software. Process and Infrastructure Improvement: Own the automated testing platform to enhance the efficiency, accuracy, and level of automation for BMS control system verification. Support continuous test infrastructure improvement, including writing and debugging test scripts on HV HIL systems. Cross-Functional Collaboration and Integration Coordination and Liaison: Coordinate all integrated BMS test infrastructure and verification activities across Archer teams. Serve as the verification liaison between the Systems Engineering organization and the High Voltage Power System / BMS's Controls and Software groups. Integration Activities: Perform essential integration activities for the BMS in the dedicated battery labs and integrated system labs. Feedback and Resolution: Provide feedback on issues and verification gaps discovered during integration to the relevant System/Software teams and collaborate on effective resolution and subsequent verification. Lab Stakeholder: Collaborate with lab staff to ensure continuous improvement of process and infrastructure, and assure the continuity of integration learnings into both prototype and production aircraft functional testing. Cross-Functional Alignment: Work closely with mechanical, electrical, system architecture, software development, and integration teams to understand new component-level hardware changes and ensure corresponding software support. Compliance, Reporting, and Safety Certification Support: Maintain traceability between requirements and test results, generating all required artifacts to support software certification. Data Analysis: Analyze test data and present clear summaries via dashboards and failure reports. Failure Analysis: Investigate and lead device failure analysis to determine root cause, driving subsequent product improvements.
