As the renowned digital assets exchange in Brazil (voted best 3 times in a row by the largest Bitcoin community) and elected the most secure by aCCESS Security Lab and Passfolio, by independent research, Walltime is growing fast. Our current focus is exchange BRL ⇔ BTC in Brazil but we intend to launch additional cryptocurrencies, others fiat currencies and operate in multiple countries.


Walltime is a technology company at heart — launched by a cryptocurrencies expert & an experienced IT executive. Built by an amazing team — and we strongly believe in doing code right, even when it takes longer and costs more. We have a deceptively simple user interface hiding a huge level of sophistication and care underneath.

To support this growth while keeping our reputation of excellence we are hiring worldwide.

Current opportunities are in software development (we are a functional programming shop - we do Scheme, Clojure, Javascript, Java & Python), support and operational, finance, administrative roles, accounting, marketing and design. For software developers only, we demand an advanced English (Portuguese knowledge is optional); for other positions we currently require fluency in Portuguese and also English proficiency.

To build and keep an excellent team we seek for high potential candidates, and we understand that very capable people under-perform in traditional interviewing processes. An important reference to understand our perspective on hiring: The Hiring Post, by Thomas & Erin Ptacek.

Our team is diverse — we already had in our team administrators, aeronautical and mechanical engineers, system analysts, musicians, computer scientists, lawyers and law students, economists and programmers (among other profiles). At Walltime we encourage independence and give the opportunity to exercise real influence in the company. We are looking for autonomous people who like challenges of this type.

Walltime is a distributed company with the majority of employees working remotely at full time (although we hang out occasionally). Our headquarters office where the minority non-remote staff works is in the CambuĂ­ neighborhood in Campinas, SP, Brazil.
