DevOps & Technology Controls Engineer
📍 Kraków
🏢 Hybrid model – 6 days per month in the office
We’re looking for skilled individuals to join the DOME Payments Team, working in a mission-critical environment across a broad range of technologies—from vendor products to in-house developed microservices. With ever-increasing real-time customer demands, our key business drivers are platform availability and service stability.
This is a hands-on role for someone who can work autonomously, bring order to complexity, and drive delivery while keeping risk under control including Vulnerabilities and patching activities.
As a DevOps Engineer, you’ll primarily dedicate your time to both Run the Bank and Change the Bank activities—supporting projects that deliver new services, integrations, and enhancements. Support spans mainly EU and UK services and integration layers. Day-to-day responsibilities include pipeline support, consultancy, IT service oversight, guidance to L1 support teams, Service Management, Quality Assurance, security patching, and a wide range of related activities such as Change Management, design and testing.
YOUR RESPONSIBILITIES
- Own the day-to-day reliability, change delivery, and continuous improvement of a complex SEPA payments technology estate spanning IBM WebSphere Application Server (WAS), IBM MQ, Oracle, SFTP integrations, APIs, and microservices running on Kubernetes
- Engineering work consisting of building and supporting CICD pipelines, working on the delivery of orchestration solutions, support and maintenance of payment services, service oversight and a service management activity
- Manage incidents end-to-end: assess impact, coordinate teams, keep stakeholders updated, restore service quickly, and complete root-cause reviews with tracked actions
- Maintain clear support guides (runbooks), on-call readiness, and service health monitoring with effective alerts and dashboards
- Support IBM MQ and IBM WAS to ensure reliable connectivity and performance, including security (TLS), configuration, tuning, and troubleshooting message flow issues
- Support application connectivity to Oracle, working with DBAs on performance, connection management, and resilience (HA/DR)
- Manage secure SFTP integrations, including keys/certificates, automated transfers, monitoring, and operational controls
- Ensure file/batch and message-based processing meets agreed SLAs, with strong traceability and audit readiness
- Operate microservices on Kubernetes, covering deployments, scaling, configuration, secrets, ingress, and observability (and service mesh where used)
- Improve CI/CD and release practices across both WAS-based applications and Kubernetes workloads
- Work with API and engineering teams to standardise operational best practice (health checks, SLOs, logging, metrics, and tracing)
- Automate repeatable tasks (provisioning, deployments, drift checks, patching, and validation) using scripting and/or Infrastructure as Code
- Strengthen operational maturity through consistent standards, high-quality documentation, and SRE-style practices (SLOs, error budgets, blameless post-incident reviews)
- Coordinate changes across teams and components, balancing delivery speed with stability and payments regulatory expectations
- Communicate clearly with both technical and non-technical stakeholders on status, risks, dependencies, and timelines
- Take ownership of outcomes: identify blockers early, drive resolution, and keep work progressing
- Help in ITSO activities, helping drive service health, sustainability, and operational readiness—ensuring proper service governance, clear ownership, effective incident/problem follow-up, and continuous improvement across the stack
- Risk and Control is a core part of the role: help to identify and manage operational and technology risks, maintain robust controls (including audit-ready evidence), support risk assessments, and ensure compliance with required standards and change processes
- Co-ordinate delivery and operational priorities, mentoring and supporting colleagues, setting good engineering and operational practices, and partnering effectively with stakeholders across projects, support teams, and vendors. Teamwork is pivotal to our success and underpins daily interactions
- Working closely with various stakeholders located in different places in the world
SKILLS & EXPERIENCE WE REQUIRE
- Fluency in English,
- Strong hands-on DevOps/Platform Engineering experience in a regulated, high-availability environment (payments/financial services strongly preferred)
- Proven experience running workloads on Kubernetes (deployments, scaling, config/secrets, troubleshooting)
- Strong operational knowledge of Oracle from an application/platform perspective (connectivity, performance triage, HA/DR concepts; DBA collaboration)
- Experience in SQL
- Experience in Linux
- CI/CD and automation capability (e.g., Git-based workflows; scripting in Bash/Python; configuration management/IaC preferred)
- Strong experience IBM MQ support and troubleshooting (including security/TLS and performance)
- Strong experience supporting IBM WebSphere Application Server (WAS) in production
- Experience managing SFTP integrations securely and at scale (keys/certs, automation, monitoring)
- Observability and troubleshooting strength: logs/metrics/traces, performance tuning, capacity
- Following Agile & DevOps working methodology and tools (Jira, Confluence, SharePoint etc)
- High autonomy: able to prioritise, decide, and deliver with minimal supervision
- Strong organisation and management skills: plans work effectively, handles competing priorities, and drives actions to closure
OPTIONAL/NICE TO HAVE
- Experience in Payments (e.g. SEPA) is an advantage
- Experience with API gateways/management, service mesh, container security, and vulnerability management
