    Description
    About IEX
    At IEX, we're passionate about building technology that moves industries forward. Our story began when we built a stock exchange designed to deliver high-performance results for all investors. Our belief is that technology should level the playing field so that opportunity is equitable. We are applying what we learned from building a high-performance stock exchange to build technology that solves for complexity and accelerates growth in other areas. We aspire to build a trusted, disciplined, and diversified business. Our goal is to build transformative technology without ever compromising our integrity - and we're just getting started
    About the Role
    We're looking for a Platform Engineer, Development to design and build high-performance tooling and infrastructure that supports QA testing, simulation environments, and core developer workflows. This role is critical to improving automation, scalability, and reliability across engineering, and will play a key part in how teams build, test, and deploy software.
    You'll contribute directly to the platform's technical foundation - writing clean, efficient code, improving internal tooling, and enhancing the developer experience. This is a hands-on role for a strong engineer who enjoys solving deep technical problems, debugging complex systems, and collaborating with teams across the organization.
    What You'll Do
    • Design, build, and maintain platform tooling for QA testing, simulation, and deployment workflows.
    • Develop performant, maintainable systems primarily in Java and C++.
    • Automate deployment processes and streamline tooling for Linux environments.
    • Partner with QA, Data, and Development teams to improve testing coverage, reliability, and developer efficiency.
    • Handle straightforward bug fixes and contribute to platform-level codebases to ensure stability and usability.
    • Evaluate new technologies and approaches to optimize platform performance and internal developer experience.
    • Create clear, reproducible documentation and help establish platform engineering best practices.
    • Collaborate closely with downstream teams to gather requirements, clarify needs, and support platform adoption.
    What We're Looking For
    • Strong programming skills in Java and/or C++.
    • Demonstrated experience building engineering tools or internal platforms - not just using them.
    • Strong Linux fundamentals, including deployment workflows, scripting, debugging, and automation.
    • Ability to troubleshoot issues, contribute to shared codebases, and improve internal platform reliability.
    • A tinkerer mindset - curious, self-directed, and comfortable figuring things out independently.
    • Excellent communication skills and the ability to work effectively with QA, Development, and Data teams.
    • Financial services experience is a plus but not required.
    • Rust and/or Python experience preferred.
    Why you should apply:
    • Comprehensive Benefits
    • Unlimited PTO
    • 100% coverage for medical, dental, and vision
    • New hire stock equity (RSUs)
    • 401K employer match
    • OneMedical membership
    • 16 weeks paid parental leave
    • Flexible workplace
    • Employer charity match
    • Learning stipend
    • Commuter benefits
    • Jump Start onboarding program
    • Internal mentor program cross-departmentally
    • Friendly and inclusive workplace culture
    Here at IEX, we are dedicated to an inclusive workplace and culture.
