Pros

Good industry because not too many companies making optic network devices and the competition is relatively low.

Cons

- Very high turnover rate since 2014, hired around 10 new VPs and replaced or left about 5. About 5 directors were hired and then fired within less than a year. - Most political company I ever seen - when they don't like someone, they will make rumors to blacken him/her. - Horrible system test and automation team - they don't know how to reject unreasonable requirement and they can't find valuable bugs using minimum resources. They wasted too much money on outsourcing.

Pros

Calix offers a highly collaborative, customer‑first environment where strong cross‑functional partnerships are genuinely valued. The culture encourages ownership, accountability, and proactive problem‑solving, especially when supporting high‑impact customers and complex initiatives. Leadership is accessible and supportive, and there’s a real emphasis on continuous improvement, process refinement, and professional growth. If you enjoy meaningful work, transparency, and being trusted to make decisions that positively impact both customers and the business, Calix is a great place to build and grow your career.

Cons

As with many fast‑growing, customer‑focused organizations, the pace at Calix can be demanding, particularly during peak periods or when managing complex, cross‑functional initiatives. Processes and tools are continuously evolving, which can occasionally create ambiguity and require adaptability. Aligning across multiple teams and priorities sometimes takes persistence, and success often depends on being proactive, detail‑oriented, and comfortable navigating change. That said, these challenges tend to come with opportunities for visibility, impact, and growth.
