Senior Full Stack Developer Jobs in Edgartown, MA

Spear AI is seeking an engineer to provide DevOps and infrastructure for the embedded software team on our hardware platforms. This person will also serve as an informal interface between the embedded software team and the company-wide software group, reporting to the VP of software but co-located with the hardware team.
Your job will be to provide best practices for HIL, SIL, CI/CD, Deployment, Provisioning, Configuration, etc., to the firmware team using Spear AI’s cloud-based infrastructure and applications.
