About The Position

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.

Requirements

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.

Nice To Haves

Financial services experience is a plus but not required.
Rust and/or Python experience preferred.

Responsibilities

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.
