Senior Platform Engineer (Architect)

Trading Technologies is in the middle of a massive infrastructure shift within the high-stakes world of capital markets. We’re removing our legacy VMware datacenter, upgrading our Red Hat ecosystem, and modernizing our AWS footprint to support low latency, high-performance trading systems. To pull this off, we’re restructuring our engineering org into dedicated Cloud and Platform teams.

If you are looking to gain deep, hands-on experience building the highly robust, low-latency platforms that power capital markets, this is your chance. We need a Senior Platform Engineer to join the new Platform Team. Your main goal?

Make life incredibly easy for our developers while maintaining the ironclad reliability our industry demands. We want to stop treating infrastructure as a ticketing system and start treating our platform as a product. To do that, we are making Backstage the center of our universe, building it out as the core data model and source of truth for all of our platform engineering operations Role will be expected to be on call as part of the standard on call rotations.

Own Backstage: You will architect and build out Backstage so it acts as our central software catalog, holding all the metadata, ownership data, and telemetry for our high-performance engineering systems. Modernize Deployments: Our current deployment pipelines need an overhaul. You’ll help us move toward modern practices (GitOps, containerization, progressive delivery) so developers can ship code without friction—and without breaking critical financial workflows.

Fix the DevEx: Build "golden paths" and self-service tools that abstract away the complexity of AWS. If a developer needs infrastructure, they shouldn't have to wait for someone to click buttons. SRE in Capital Markets: Bring your deep Linux SRE expertise to an environment where microseconds matter.

You’ll support the upgrade and optimization of our Red Hat (RHEL) environments while we actively migrate latency-sensitive workloads off VMware and into a modernized AWS setup. ) to ensure everything we build is reproducible, version-controlled, and tuned for maximum performance. Pipelines: create and improve the pipelines to drive quality, and ensure that what we deliver does not put our services at risk.

Experience: 7+ years primarily focused on Platform Engineering, SRE, or modern DevOps. Platform & DevEx Focus: You genuinely care about the developer experience. You have real experience building Internal Developer Platforms (IDPs), and ideally, you've gotten your hands dirty configuring Backstage plugins and data models.

Linux / SRE Chops: You are a Linux expert, specifically with Red Hat Enterprise Linux (RHEL). You know how to tune the OS for performance, troubleshoot complex issues, and scale systems under heavy load. Cloud Modernization: You know your way around AWS and have a track record of moving workloads out of legacy on-prem datacenters (especially VMware) into the cloud.

Deployment Mastery: You are highly familiar with modern CI/CD, container orchestration (Docker/Kubernetes), and GitOps (ArgoCD/Flux). Scripting: You can write solid automation and tooling in Python, Go, TypeScript (helpful for Backstage), or Bash. Bonus Points You’ve contributed to open-source tools or built custom Backstage plugins.
