Site Reliability Engineer – Equity Trading Platform

Location: New York | Practice Area: Capital Markets - Technology & Engineering | Type: Permanent

Keep critical equity trading platforms resilient, reliable, and ready for the markets.

The Role

We are seeking a highly motivated Site Reliability Engineer (SRE) to join our Equity Trading Platform Engineering team, supporting critical trading applications and Fidessa flows used by internal business users and external clients.

You will focus on the stability, resiliency, performance, and availability of front-office equity trading systems across trading hours, late-evening processing, and weekend support rotations. Working closely with business users, application development, infrastructure, QA, middle office, and global support teams, you will troubleshoot complex production issues, strengthen platform reliability, and support ongoing business growth.

This is an opportunity for someone with strong technical troubleshooting skills and hands-on trading platform experience who enjoys working in a collaborative, fast-moving production environment.

What You’ll Do

• Provide front-line SRE and production support for equity trading systems and Fidessa flows, covering order routing, FIX connectivity, client onboarding, drop-copy, DMA, algorithmic trading, and high-touch/low-touch workflows.
• Investigate and resolve complex application, infrastructure, connectivity, and trading workflow issues, supporting incident response, root-cause analysis, post-mortems, and permanent remediation.
• Build and enhance monitoring and observability across applications, infrastructure, databases, messaging, and trading flows, using operational metrics to support performance tuning, capacity planning, and fault isolation.
• Develop automation, scripts, operational tooling, and CI/CD capabilities to reduce manual effort, strengthen reliability, and streamline deployments, releases, and production checkouts.
• Partner with business, development, QA, infrastructure, and global support teams to improve production readiness, documentation, operational standards, and platform stability, while participating in late-evening, weekend, and on-call support rotations.

What We’re Looking For

• Strong experience supporting front-office trading systems in a production environment, ideally within Equities or Capital Markets, with hands-on knowledge of Fidessa, OMS/EMS platforms, order routing, client connectivity, and post-trade processing.
• Strong understanding of the trade lifecycle and FIX Protocol, including FIX 4.2, 4.4 and 5.0, message analysis, session behaviour, sequence resets, rejects, cancels/replaces, drop copy, and client onboarding flows.
• Strong troubleshooting capabilities across Linux/Unix, Windows Server, networking, databases, messaging, and application layers, alongside scripting or automation experience using Python, Bash/Shell, SQL, PowerShell, or Perl.
• Experience with monitoring and observability technologies such as Splunk, Grafana, Prometheus, Nagios, Datadog, OpenTelemetry, CloudWatch, or ELK Stack, plus database and messaging technologies relevant to production trading environments.
• Clear communication, prioritisation, and problem-solving skills, with the ability to collaborate effectively with traders, business users, technology teams, infrastructure teams, and stakeholders while carefully assessing business and operational impact.

Bonus Points For

• Experience supporting Cash Equities alongside additional asset classes such as Futures, Options, ETFs, Swaps, Bonds, or Derivatives.
• Knowledge of TCP, UDP, multicast/unicast, latency analysis, firewall flows, connectivity troubleshooting, and packet-level diagnostics.
• Experience with CI/CD and DevOps tooling such as Jenkins, Bamboo, Bitbucket, Git, GitHub Actions, JFrog, Ansible, Terraform, ArgoCD, ServiceNow, JIRA, or Confluence.
• Familiarity with AWS or Azure and container platforms and tooling such as Docker, Kubernetes, OpenShift, Terraform, Helm Charts, or Lens.
• Experience supporting compliance, legal, audit, or regulatory queries relating to trading activity, client flows, production logs, or production events.
