Role Description We’re looking for a Software Development Engineer in Test (SDET) who can leverage their depth and breadth of experience to help us continue to grow our platform while maintaining high standards for efficiency, quality, performance, integrity, and technical excellence. Index’s exchange operates at a global scale, handling millions of transactions every second of every day. Achieving our mission means holding the highest bar for Quality (functional, performance, reliability, resiliency, efficiency, yield) at all times; every millisecond quite literally counts in our business. What we’re looking for: - Leaders: You know how to work with a team of engineers, mentoring and guiding members of the team, as well as leveraging your own knowledge and experience to make sound decisions. - Problem Solvers: You are tenacious at finding solutions and find creative ways to solve problems while working with others amicably and presenting your viewpoints. You like figuring out where things break so others can collaborate to make them better. - High Standards: You take the quality of every release personally. You have a passion for building comprehensive test suites for complex software, and bring a robust CI/CD DevOps tooling culture to bear to keep the signals flowing. - Knowledge Hungry: Learning new frameworks and languages is exciting to you – you’re not satisfied with the status quo. Our solution space exists on the cutting edge. Here’s what you’ll be doing: - Testing the control plane for cutting edge programmatic ad tech that touches millions of users every single day. - Operating side-by-side with platform and feature engineers, developing comprehensive tests for each build as a core component of the quality strategy and SDLC. - Interpreting functional requirements and designs to plan, develop, execute, and automate the full spectrum of validation, operating a crucial gateway on the critical path to production. - Driving daily test result reviews, issue diagnosis, resolution, and closure. - Leading or assisting in data analysis to determine data health and consistency, or root cause of issues. - Identifying and addressing gaps in testing over time, proactively as well as through responding to release blockers and production incidents. - Taking long-term responsibility for an ever-improving test suite. - Being a key technical leader in driving the architecture evolution of our software/data test automation framework and related capabilities. - Leading the definition, design, development, documentation, and maintenance of tools, test cases, and automation frameworks. - Providing feedback and influence into the design process to help us build a testable platform, applications, and data models. - Designing and building quality, performance, and reliability in from day one, and inspiring other team members to do the same. Here's what you need: - You are a talented, fast learner and embrace change. - 5+ years of experience as a Software Engineer. - 3+ years designing and implementing automated validation systems, test infrastructure, or developer tooling as production-quality software. - Experience designing and building simulation software to validate functionality and performance of end-to-end software solutions. - Experience validating high-throughput, low-latency distributed systems where correctness, resiliency, and performance characteristics matter at scale. - A passion for designing, writing, and testing high-quality code. We use a lot of different languages and frameworks including JavaScript (Node, React), Golang, MySQL and more. - Experience in performance test design, load modeling, profiling and identifying systemic bottlenecks in distributed systems. - Excellent problem-solving skills, the ability to think differently, and an understanding that compromise, negotiation and practicality are important qualities. - A desire to work with and learn from the people around you – we greatly value people and interactions. - We’re looking for the right combination of personality and ingenuity to push our product to the max, inspire those around you and have fun doing it.
