Senior DevOps Engineer

Senior DevOps Engineer, EMEA

Interested in becoming a key technical contributor supporting EMEA operations for a global financial-technology environment? We'd like to hear from you.

Work arrangement: Fully remote Region: EMEA Preferred locations: Belfast, Northern Ireland / Dublin, Ireland

Own production operations across EMEA for a U.S.-based financial technology company supporting global financial markets.

Xelure Technologies is recruiting on behalf of our U.S.-based FinTech partner for an experienced Senior DevOps Engineer to take a key role in supporting its clients and production operations across EMEA.

Our partner is a U.S.-based financial technology company providing technology and services supporting sophisticated financial-market participants. Its environment sits at the intersection of internal technology, external systems, and business-critical financial workflows.

Our partner operates a remote-first model in EMEA, with an existing distributed team across Northern Ireland. While there is currently no physical EMEA office, the team occasionally comes together in Belfast for in-person training, collaboration, and team-building, so some travel will be required.

The role also includes participation in weekend and/or on-call coverage rotations, with the specific schedule and frequency determined by operational requirements.

The Role

As the Senior DevOps Engineer supporting EMEA, you will be a senior-level individual contributor, not a people manager, with significant autonomy and hands-on responsibility for production support, incident response, troubleshooting, automation, and customer-facing technical operations during EMEA hours.

You’ll go beyond monitoring and escalation by investigating issues, making evidence-based technical judgments, communicating clearly with customers and colleagues, and knowing when to resolve problems independently or bring in the right specialists.

Working across production systems, applications, databases, networking, logs, and monitoring tools, you’ll also help strengthen operations through better automation, runbooks, documentation, incident management, and observability practices.

What You'll Be Doing

Monitor and support business-critical production environments during EMEA operating hours, responding to alerts and owning routine Level 1 incidents and service requests through resolution or appropriate escalation.

Troubleshoot across Linux systems, applications, databases, networking, customer connectivity, and external dependencies, using logs and system data to investigate customer-specific activity and identify failure domains.

Communicate clearly with customers and internal teams during incidents, providing accurate updates even when the root cause is still being investigated.

Develop Python, shell, and utility scripts to automate operational tasks and improve efficiency.

Work with PostgreSQL, including connectivity testing, data loading/dumping, schema-related troubleshooting, and query optimization.

Support Git and CI/CD workflows and troubleshoot deployment and operational issues.

Work with monitoring, logging, alerting, and observability tools, contributing to improvements in operational visibility and practices.

Improve runbooks and knowledge documentation, participate in postmortems, and help strengthen incident-management processes.

Participate in weekend and/or on-call coverage rotations based on operational requirements.

What We're Looking For

Technical Background

You should bring strong hands-on experience with:

Linux production environments, including shell, SSH, filesystem navigation, systemctl, cron/crontab, sudo, and production-safe troubleshooting

Linux log investigation, including tools such as grep, awk, sort, and uniq and working efficiently with large or compressed log files

Python 3, particularly scripting, automation, operational tooling, and one-off utilities

PostgreSQL, including connectivity, querying, dumping/loading data, schema concepts, and query optimization

Message buses and middleware technologies, including troubleshooting communication and integration between systems

Git and CI/CD pipelines

Networking fundamentals, including connectivity testing, DNS, and VPN troubleshooting

Monitoring, logging, alerting, metrics, and observability tools

Ansible and infrastructure/operational automation

Financial markets experience, with hands-on exposure to capital markets, trading technology, or financial-services environments, including B2B customer support and business-critical systems connecting internal applications with external or customer platforms. Fix Protocol a plus but not required.

The Way You Work Matters

The strongest candidate will be someone who:

Remains calm and communicates clearly when production issues are unfolding.

Can confidently explain what is known, what is not yet known, and what is being investigated.

Uses evidence rather than assumptions when troubleshooting.

Knows when a quick operational fix is appropriate and when deeper investigation is necessary.

Can deal professionally with customers who may be under pressure because of an incident.

Is comfortable operating independently in a highly asynchronous, distributed environment.

Communicates clearly when blocked and knows when to ask for help.

Enjoys learning unfamiliar systems and expanding their technical range.

Documents what they learn rather than allowing important knowledge to remain tribal.

Has excellent spoken and written English.
