Our benefits

At Calix, we strive to provide work that’s rewarding, innovative and impactful.

As part of a purpose-driven team committed to solving global challenges, our people are given the opportunity to grow both personally and professionally.

We understand our people are more than employees, so we also provide benefits to foster balance and wellbeing, and build connections to community.

Flexible working

Calix offers flexible working arrangements to support employees to be their best at work and home. Core collaboration hours, working from home arrangements and office hours are agreed on a case by case basis.

Calix proactively fosters employees’ professional development and career progression. Through an annual review, every employee creates a development plan with their manager that includes personal development and growth objectives linked to their strengths, passions and interests. 

An Employee Incentive Scheme (EIS) provides employees with rewards for performance to enable them to hold a stake in the company they are working diligently to build, also aligning their interests with shareholders.

Mental health and wellbeing are important aspects of Calix’s strong safety culture. Employees and their families can access an independent Employee Assistance Program (EAP) for confidential support and counselling when personal, family or work-related concerns are affecting their health and wellbeing.

Calix is committed to prioritising and investing in the health and wellbeing of our employees, offering additional leave in some locations for employees to dedicate to their physical and mental health and wellbeing.

Calix supports parents to build connections with their families, offering unpaid and paid parental leave for primary and secondary caregivers in some locations, as well as support to enable parents to maintain connections with the company and a successful return to the workplace.

Calix supports access to healthcare for its employees and their partners, in some locations, by subsidising and providing access to health insurance providers.
