What You'll Do

• Provide production support for critical internal trading, integration, and event-driven messaging platforms across user-acceptance and production environments. • Diagnose and resolve application, messaging, infrastructure, connectivity, latency, throughput, and data-delivery issues; coordinate escalations with subject-matter experts and external vendors as needed. • Communicate clearly and promptly with trading staff and internal stakeholders during incidents, platform disruptions, releases, and exchange-related events. • Partner with global teams across North America, Europe, and APAC to deliver seamless production support coverage and coordinate incident, problem, change, and release-management activities. • Monitor platform health, identify emerging risks, and strengthen operational readiness through dashboards, alerting, capacity planning, runbooks, post-incident reviews, and root-cause analysis. • Design, implement, administer, and support Solace PubSub+ event-driven integration solutions, including event brokers, message VPNs, client profiles, queues, subscriptions, ACLs, certificates, authentication, authorization, and monitoring. • Establish and maintain event-driven architecture standards for topics, schemas, versioning, security, retention, resiliency, and lifecycle management; use Solace Event Portal and AsyncAPI-based practices to govern reusable event contracts. • Develop source-controlled automation, configuration, and operational tooling using Python, shell scripting, GitHub, Artifactory, CI/CD pipelines, and infrastructure-as-code practices to improve reliability, observability, deployment, and recovery procedures.

What You Bring • Experience supporting business-critical production systems in a fast-paced environment, ideally within financial services, trading technology, or another highly available enterprise setting. • Hands-on experience with Solace PubSub+, including broker configuration, queues, topics, subscriptions, ACLs, client connectivity, routing, and operational support. • Strong knowledge of event-driven architecture, asynchronous messaging, distributed systems, and integration patterns, including one or more of JMS, AMQP, MQTT, REST, WebSocket, or SMF. • Strong Linux skills, including command-line troubleshooting, log analysis, process management, networking fundamentals, and shell scripting. • Strong Python and shell scripting skills, with experience automating platform operations, environment management, configuration, deployment, monitoring, validation, or recovery. • Experience with GitHub and Git-based workflows, including pull requests, branching strategies, CI/CD practices, and artifact repositories such as Artifactory. • Demonstrated ability to troubleshoot complex incidents across application, messaging, infrastructure, and network layers, while communicating effectively with technical teams, business stakeholders, and trading staff. • Bachelor’s degree in Computer Science or a related field.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
