Job Overview

At Yellowbrick, we’re building the world’s most advanced, parallel, scale-out elastic cloud data warehouse. It is in business-critical use at dozens of large enterprise customers who depend on it for their operations. It runs in public clouds and on-premises. Our software scales out to hundreds of nodes on multiple clusters. It’s a complex software stack, highly available, supports replication for disaster recovery, and shouldn’t go down. Our R&D team solves the hardest computer science problems at all levels of the stack. What we do isn’t easy: We design hardware, build an SQL UI for Kubernetes, build an operating system, have created an entire enterprise-grade database from scratch with remote support capability, and actively build and maintain business continuity functions and a growing set of ecosystem integrations.

We are looking for a highly motivated and driven engineer to join our quality team, finding new ways to break our product end-to-end, modelling customer workloads, qualifying releases and creating new scenarios that take the entire stack and permutation volume into consideration.

You’re an individual that takes pleasure in looking at the solutions holistically. Where others see software that seems to work well, you imagine all the holes and are passionate about finding them. You think about the use cases and patterns of customers and ensure the entire experience not only functions as expected but is resilient to deviation.

You love automation of everything, appreciate randomness, and are comfortable in taking a white-box, black-box, and grey-box approach to end-to-end systems testing. You’re familiar with asynchronous, reactive programming and understand how to poke holes in a software stack. You’re good at SQL and understand the basics of database architecture. You love containers and Kubernetes and are comfortable building automation that makes the best use of these technologies. Endless curiosity means that, whenever a customer encounters an issuein the field, you ask yourself “how come we didn’t find that?”

Responsibilities

Review functional/unit coverage and identify the gaps in the full system plan
Develop new and exotic test cases to break our software stack from start to finish
Understand how different workloads, data sets, and use cases change the test scope and focus of the validation
Monitor and document client load impacts new software versions
Automate the cases defined and be responsible for the maintenance and evolution of the use cases as new capability is introduced in the product

Qualifications

2-5 years of experience testing complex software stacks
Strong knowledge of and experience with automation tools
Strong scripting skills in python or other high-level languages
Strong debug and analysis skills of failures and failures patterns
Strong correlation skills with failure patterns and existing validation capabilities
Good working knowledge of cloud monitoring
Good working knowledge of chaos injection
Good working knowledge of SQL
Good communication skills
Fundamentals – as many of these as possible:

Black and white-box testing experience
Networking – error injection, benchmarking and monitoring, TCP and/or RDMA
Experience testing concurrent and distributed systems
Experience testing highly available software stacks
Understanding of transactional databases
Authentication protocols and APIs
Observability – monitoring, logging, tracing stacks
Basic database operations – load, unload, backup and restore
Experience with data generation tools
