About Toptal

Toptal is a global network of top freelance talent in business, design, and technology that enables companies to scale their teams, on-demand. With $100+ million in annual revenue and over 40% year-over-year growth, Toptal is the world’s largest fully remote company.

We take the best elements of virtual teams and combine them with a support structure that encourages innovation, social interaction, and fun. We see no borders, move at a fast pace, and are never afraid to break the mold.

Position Description

Toptal is a quality-first company. While quality is the responsibility of the whole team, our Software Engineers in Test lead this effort. We believe that top quality can only be reached by ensuring this on the product, engineering, and team level. We believe that QA is more about communication and collaboration over documentation and processes and because of that, we follow a holistic approach.

In reference to the product, you will work closely with product managers to ensure the team builds the proper software that reaches company goals and brings value to its users. In reference to engineering, you will support fast and reliable delivery of software, leading and coordinating software assessment and testing activities. Last but not least, in your team, you will lead process transformations to improve quality and mentor your teammates to achieve exceptional quality outcomes.

You will be working in one of the multiple teams that make up the Growth Squad. Some teams focus on building content and applications that increase our engagement with prospective talents or clients, while other teams will work on the foundations - tools that streamline content creation and administration.

Every bit of work you do will have a direct impact on the company’s revenue.
