That’s why we focus on making your day-to-day the best it can be while empowering you to achieve your goals and aspirations.    What does that mean?   - It means you’ll have the autonomy to make your own decisions and focus on what’s important to you and your role. - It means having access to a senior team that supports you and wants to see you succeed. - You’ll have a smart team you can learn from, collaborate with, and grow with. - It means being able to make an impact and have a voice in the future of the feature, product or company direction.

And when we say we only hire top talent, we actually mean it. Because of this, our interview process is different too - and we’re proud of it.  We let your work do the talking. We don’t go in for six rounds of interviews, live whiteboard or live-coding. We don’t hire people that can talk a good game. We only want the best. And for that, we need to see what you can do,  in your own time, in your own way.  For real.   But interviews are a two-way street. Through the project, you’ll get a real taste of life at Teleport, including:    - We’re flexible - you’ll have plenty of time to complete your project, if life gets in the way, that’s ok. We can - work around you.  - We give you autonomy  - you’ll have the space and freedom to figure things out, make decisions, and problem-solve. - We’re collaborative -  Got questions? - We have answers. You’ll have support from your team - the one you’ll be working with day in day out if you’re successful in getting the role. - We progress careers - During the project,  see how much you learn. That’s what working at Teleport is like. We like learning, on the job. All-the-time.  - We can move fast (if you can) - two weeks sound like a long time? No problem? Early submissions are fine, and we’ll keep the process moving.    Think you’ve got what it takes? We’d love to see it! Unconvinced? We can guarantee three things:  - It’ll challenge you. - You'll learn a lot.  - If you love the process, you'll love working at Teleport.   Teleport is an equal opportunity employer and does not discriminate against any employee or applicant on the basis of age, color, disability, gender, national origin, race, religion, sexual orientation, veteran status, or any classifications protected by federal, state, or local law.   Candidate Privacy Notice: For information about our collection and processing of job applicant personal data for this position, please see our Job Applicant Privacy Policy and Notice of Collection at https://goteleport.com/legal/apply/job-applicant/
