Principal Engineer
Confirmed on the employer's own hiring board on Oct 9, 2026. First seen by Alion on Oct 6, 2026.
About the role
SteelEye, now merged with FundApps, provides communications, trade and order surveillance to some of the world’s largest financial institutions.
As a Principal Engineer you will set technical direction across the Surveillance estate and work through our most senior engineers on its hardest problems.
We deliver enterprise SaaS to hundreds of clients, many of them running the same platform under very different regulatory, security and scale expectations, and doing that well is an engineering problem in every layer rather than an operational one. Delivery sits with the teams building our products. What sits with you is whether the whole thing holds together: whether the architecture is coherent, whether the standard of engineering craft is rising, whether the security model makes sense end to end, whether we know production is working, and whether our most senior engineers are getting better.
Our clients expect strong technical assurance and our platform runs across AWS and Azure. The decisions you influence determine how safely teams can make changes, how quickly we can activate clients and how efficiently we can operate.
This is a Principal role with real leadership attached, and it stays technical. You will stay hands on: reviewing architecture, reading and writing code, and joining incidents. The role moves between deep technical detail and a 10,000 foot view, often on the same day.
