Senior Embedded Engineer

About the role

The Systems is responsible for owning the complete lifecycle of hardware products, ensuring that each circuit path is meticulously managed from initial schematic capture through to deployed firmware updates in the field. You will translate abstract sensor concepts into concrete and robust hardware and firmware implementations that reliably function across the distributed hub ecosystem. This role requires close collaboration with engineering peers in both Lviv and Kyiv, while granting you the local authority to make technical and product decisions for your assigned scope. You will actively participate in defining product requirements, validating hardware revisions, and coordinating with distributed stakeholders to align on goals. A core part of your work involves designing circuit behavior and writing firmware for complex sensor modules and hub platforms that are built upon the Malevich OS foundation. You will coordinate the intake of hardware change requests and user feedback, converting this input into concrete and actionable improvement targets for the product. The position also requires you to define partner interfaces to guarantee reliable communication between mobile applications and updated hub firmware. Additionally, you will implement integration tests that validate sensor drivers and network stacks under diverse load conditions to ensure system stability.
