The Pros and Cons of Working at a Startup Company

The Good• It's a unique experience

• You learn A LOT

The Not-So-Good

• The workload is heavy

• Job stability/security

Some more Linux Kernel BSP stuff.

• Customer – Israeli network equipment production company.• Product - Beamforming Wi-Fi solutions for indoor & outdoor deployments

of 3G/4G data offload, Wi-Fi access and enterprise networks.

Embedded Projects

• Knowledge of Linux and Linux Kernel is a key to success.• Get acquainted with Git + Gerrit for version control and code review;

Jenkins for continuous integration.• Medical projects last long, development and test process should

comply with respective quality regulations norms. Tasks and schedule are well defined and documented. Big “paperwork” overhead.

• While working for start-up projects be prepared to work hard on many topics from different areas. The scope of work is undefined. Schedule is tight.

• Automotive projects are trending now.
