About the Position

The Senior QA Engineer will be responsible for ensuring our software platform meets the high functional, stability, and performance standards of Gradient. You’ll have a unique opportunity to shape the development of our privacy-preserving, low-latency, highly distributed compute infrastructure and the services it empowers.

You will work closely with the rest of the engineering team to understand the features and technical implementation, to develop and manage Gradient’s build and scripting environment, and to develop test plans, automation, and test suites that approximate real-world environments, customer use cases, and business needs to ensure proper functionality, improve the stability of the existing network, and develop test automation for future services.

You will work closely with our managers, PMs, developers, and other stakeholders to build and expand testing coverage for our applications. You will develop test plans and build regression suites, and own the quality of features that form the building blocks of our platforms.

This is an opportunity to be a key contributor to a world-class, highly scalable, distributed, low-latency platform that delivers best-in-class privacy and security services.

Why Gradient

Gradient Technologies® is a Boston-based, venture-backed technology company building a trust fabric for the connected world.

At Gradient we see a world in which the authenticity and integrity of every electronic device, the software it operates, data it originates, stores, and computes, are provable qualities by construction. Gradient is committed to getting security right, without sacrificing privacy. We have developed a truly full-stack approach to security: from secure software architecture and fault tolerant distributed systems to firmware and OS modules, state-of-the-art anonymous cryptographic signatures -- all the way to state of the art secure enclave processor hardware architecture. Our technology stack is the culmination of decades of secure architecture, systems, and cryptography research at MIT, Brown, Berkeley, and elsewhere.

Advised by industry leaders from healthcare to finance, our founding team comprises world-leading experts in cryptography and secure hardware. We believe in taking a first principles approach to problem solving — and share a common desire to build impactful technology for the betterment of society. In previous lives, Gradient team members have built human brain-machine interfaces, the Macbook Air, satellite constellations, and mission critical hardware and software. (We’ve also been known to, for example, hack the office espresso machine — sometimes open loop temperature control just don’t cut it.)

We have a lot to build! If you are a talented, productive, and curious engineer excited by a startup environment and comfortable tackling lightly scoped problems with others of your caliber, then at Gradient you will have the opportunity to help build and shape the technologies that bring much-needed reform to the field of secure systems.
