Where & How We Work

We are a global, diverse group across age, gender, and race and offer a truly flexible and family friendly work environment. Kids, pets, and the occasional delivery person are all actively encouraged to appear on our Zoom screens. All of us at Linktree work either fully remote or a hybrid "remote, but in-office sometimes" approach and that will continue even when COVID is behind us.

We currently have offices in Melbourne, Sydney and LA is coming next, but our team is spread across Australia, United States, and New Zealand. Growing from 20 people in early 2020, to 50 in 2021 and over 200 in 2022, Linktree is still growing!

Being globally distributed doesn't mean working to one timezone and we offer autonomy and flexibility in how you structure your days and weeks. There will be the need for some collaboration outside of a "normal" 9-5 being a global company, but we aim to work asynchronously where possible.


Our Culture & Benefits

Linktree's company culture and values are based around collaboration, diversity, inclusion, and flexibility. Those are all nice words but to give you some more specific examples:

- We recognise that each person is unique and have designed our benefits with this in mind. Each person has up to $6000 AUD annually to spend across Wellness, Growth, Lifestyle, and Impact pillars. This could be spent on things like (but not limited to): fitness memberships, development courses, books, childcare, pet insurance, mental health support, bike equipment, travel, or green energy initiatives.

- Employee Stock Option Program - we want each and every employee to share in the company’s success as we go further together.

- We have a paid 18-week parental leave program that is inclusive of birth and non-birthing parents and supports the whole parenting lifecycle. We also offer 4 weeks of paid leave for early pregnancy loss and the full parental leave for later pregnancy loss, in addition to a support program.

- We are proud to offer all regular full-time and part-time employees 20 hours paid volunteering leave per calendar year.

- Flexibility is at the core of Linktree, so whether you prefer fully remote, the office, or a bit of both, the choice is up to you. We trust you to get the work done.

- We have several diversity and inclusion initiatives underway, including a D&I council, training for all staff on neurodiversity, unconscious bias, and the incorporation of a transpositive inclusion policy.

- We prioritise our team's mental health, with all employees having free access to Headspace and Uprise, including 1:1 coaching sessions from qualified psychologists or counsellors.

- All Linktree staff receive $1000 AUD towards setting up their work from home space.


The Linktree Story

We created and defined the “link in bio” category in 2016 to solve a common pain point for creators, brands and businesses: they had no way to consolidate their content and digital identities. The internet was becoming increasingly  fragmented, so we launched a simple tool that allows anyone to manage their corner of the digital universe. We’re giving our users control of how the world discovers them – because why should you be defined by only one link?

Fast forward to 2022: Linktree is now used by some of the world’s biggest brands including TikTok, the LA Clippers, The UN Environmental Programme, Manchester United, and Wear it Purple, as well as celebrities including Selena Gomez, Alicia Keys, Shawn Mendes, and Dwayne 'The Rock' Johnson.

With close to 40,000 signups per day (and no sign of stopping), we’re on a mission to empower anyone to curate and grow their digital universe – come join us for this ride!



At Linktree, we celebrate and support everyone’s perspective and background, and we’re proud to be an equal opportunity workplace. We aim to foster a diverse and inclusive environment where all team members have a sense of belonging, because we believe in going further together. Linktree welcomes all people regardless of sex, gender identity, race, ethnicity, disability, pregnancy, age, or other lived experience.
