Ajax Systems

Ajax Systems is a full-cycle company working from idea generation and R&D to mass production and sales. We do everything: we produce physical devices (the system includes many different sensors and hubs), write firmware for them, develop the server part and release mobile applications. The whole team is in one office in Kyiv, all technical and product decisions are made locally.

Not so long ago we released a new version of our Hub OS and named it Malevich, now we are looking for Lead Embedded Engineer who is ready to make our system better with us. For us never could be enough: there are still a lot of new functionality, sensors, features to make our system even cooler.

Responsibility zone

• Lead a feature team of embedded engineers to achieve goals and challenges;
• Participate in the full embedded software life cycle: design, implementation, code reviews, documentation, testing and validation;
• Analysis and systematic problem solving for SW/HW reported issues;
• Cooperate with electrical engineers to perform verification of new hardware from software team perspective. Review and provide feedback on the firmware specific aspects of hardware design;
• Delivery new platforms support for Malevich OS;
• Work with high-level and technical requirements for research and development new features;
• Participate in making design decision to develop high performance and reliable embedded systems;
• Organization of stands development, needed to test platforms and track metrics (such as consumption, boot time etc);
• Be ready to mentoring of newcomers|trainee coworkers.

What we offer

With us you will enjoy:

• Working with a team of people to build the future of an industry;
• Non-trivial challenges and various range of interesting tasks;
