Role
Who you are
- 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
What the job involves
- 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
- 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
Our take
Innovations in fintech infrastructure have dramatically changed how people invest, but despite such developments, investors still face limitations when trading assets. Exchanges often list out-of-date pricing information which limits investors' abilities to make strategic investment decisions, a problem that is heightened through knock-on effects from other unstable stock prices.
IEX provides a registered US stock exchange for investors and broker-dealers, focussing on providing a more stable trade execution experience than existing exchanges. The company achieves this through its "Speed Bump" strategy that delays trades to gather up-to-date pricing information whilst assessing them for price stability, ensuring that trades are not executed based on stale data, and helping to notify other orders to react to other stock price stability levels.
Whilst the company must share the stock exchange sector with many competitors, IEX show great promise through its focus on maintaining pricing accuracy and stability. The company also stands out by providing a cloud platform for the selling, sharing, and use of financial data, in addition to an investment lifecycle advice tool for institutional investors.
