Senior Software Development Engineer in Test (SDET)
As an SDET at Radix, you will apply your boundless cunning to break distributed systems in new and interesting ways. You will study and emulate known attacks, and then concoct some new ones. You will make sure that happy path scenarios function as advertised, and that a massive array of potential error conditions all fail gracefully, predictably, and in a recoverable fashion.
During your first few months, your focus will be on creating automated tests verifying predictable pre- and post-conditions against a distributed, trustless system while coming up to speed on how the network operates and where the limitations are. With that understanding under your belt, you’ll start in on chaos testing and acting as a knowledgeable, malicious actor on our test networks.
Of course, you’ll also be contributing to test plans, highlighting gaps in coverage, creating regression tests to ensure fixed bugs stay fixed, and all the usual responsibilities of a test role. You’ll just have more fun doing those things, because we only hire fun and interesting people to work with. Your brain will bend in ways it wasn’t meant to be bent, you will form lifelong bonds with a team of incredible people, and you will forever remember the journey.
Whenever you look at a specification or an API, your mind goes straight to the edge cases.
You’re a flexible coder and are confident in your ability to learn “enough to be dangerous” if you need to pick up a new language or tool.
If asked about a familiar product or system, you have no trouble describing the various sub-systems that contribute to its overall function.
You don’t get easily frustrated when trying to nail down difficult-to-reproduce issues. You are able to methodically narrow a bug investigation down to the critical elements.
You’re intelligent and you pick up new concepts quickly. A lot of what we do here is rolling back the boundaries of known space, and there’s no playbook to refer to.
What skills do you need?
At least 3 years in a quality assurance or development role for production software.
Experience building test automation frameworks. Can write such code from scratch.
Can integrate tests in CI, e.g., Jenkins.
Experience with load testing.
Understanding or experience with BDD, TDD, or contract testing.
Docker and AWS experience is important.
Nice to have - experience with distributed systems.
At Radix, we're a team of like-minded thinkers who have long been convinced that we're living in the earliest stages of a global financial revolution. This revolution is being fuelled by decentralized finance (or DeFi for short), which is enabling an assortment of pioneering developers and entrepreneurs to re-invent almost every financial product that is currently traded and invested in traditional markets, without requiring central authorities or siloed infrastructure. DeFi has captured a great deal of attention and investment in the crypto-aware niche, growing assets under management to $90 billion in the last year. Impressive as its growth has been, its current market size isn't even a rounding error on the over $111 trillion held in traditional finance. We're focused on what it will take to go from billions to trillions.
Radix went back to first principles to come up with the right technical solution—the first layer-one protocol built specifically for mainstream DeFi—and we have already tested out at over 1 million transactions per second. We're keenly aware that the need for an infinitely scalable platform is only one prerequisite among many for mass adoption, and we're also blazing new ground in the areas of purpose-built developer tools, user experiences, and regulatory integration.
We have forged a path deep into the future of what distributed ledger technology is going to look like and we need you to come and be part of the team that is making that happen right now.

Alternatively, if you feel like you don’t match all of the requirements, we would love you to still apply anyway.
