The role is about:
We are looking for a Lead SecOps Engineer to design and build security operations for a regulated payments group: the SIEM, the vulnerability management programme, and the security incident process. You will report directly to the Head of Information Security, own the technical direction of the detection and response stack, and operate with a high degree of independence.

The force multiplier is AI. We are deliberately building a security operations model where AI agents handle alert triage, enrichment, correlation and first-draft incident timelines — so your time goes into engineering, detection logic and real incidents, not alert-console-watching.

• Location: Limassol, Cyprus or Remote from Poland or Portugal
• Reporting to: Head of Information Security

What will you do:

• Design, build and operate our SIEM from the ground up — architecture, deployment, tuning and run
• Plan and execute log-source onboarding across cloud and application estates
• Build AI-assisted triage and enrichment into the pipeline from the start: agent-based alert handling, correlation summaries, draft incident timelines
• Stand up the vulnerability management programme: deployment, asset coverage, risk-based prioritization, remediation SLAs and reporting
• Implement process and procedures to ensure an effective vulnerability lifecycle
• Operate and continuously improve the security incident process end to end: detection, classification, response, post-incident review
• Develop and maintain runbooks, playbooks and event handlers — and automate them wherever they repeat
• Harden and monitor our AWS estate: GuardDuty, Security Hub and native findings triaged, deduplicated and driven to remediation
• Drive security hardening across our infrastructure and runtime security
• Automate routine security operations aggressively — scripting, APIs, infrastructure-as-code and AI agents are all fair game
• Run proof-of-concepts, evaluate tooling and shape the technical roadmap of the security stack
• Provide security engineering consultancy to Engineering, IT and DevOps teams

What we need:

• 5+ years in security operations or security engineering in financial services or another environment with formal incident-reporting obligations (DORA, PCI DSS)
• Strong hands-on experience with SIEM platforms (Elastic/OpenSearch, Wazuh, Splunk or similar) and log pipeline engineering
• Solid AWS security knowledge: GuardDuty, Security Hub, IAM, VPC-level controls and cloud-native logging, hardening
• Practical experience running vulnerability management: scanners, prioritisation, remediation tracking
• Strong IaaC skills
• Genuine enthusiasm for AI-assisted security operations — using LLMs and agents to triage, enrich, summarise and automate is core to how this role works
• The independence to own a domain end to end: prioritise, decide, deliver and explain

Nice to have:

• Kubernetes security hands-on: admission controllers, runtime detection (Falco or similar), cluster hardening
• Detection-as-code practices (Sigma, version-controlled rules, CI for detections)
• Certifications such as CCSP, CISSP, OSCP or equivalent

Hiring Process:

• Step 1 - Thinking in Action (40 minutes) Your first conversation will be with our Talent Acquisition team. We'll explore your background, career journey, motivations, and overall fit for the role. As part of this discussion, you'll also complete a short technical screening that will be reviewed by our engineering team. This stage helps us understand both your experience and how you approach technical challenges
• Step 2 - Hiring Manager interview (60-minutes) you will meet the hiring manager Head of Information Security, to explore your skills, achievements, and alignment with the role
• Step 3 - Final Interview (45 minutes) The final stage is a group interview with senior members of our Technology squad, which may include the CTO, CPO and Head of Security. Together, we'll discuss team fit, collaboration style, expectations from both sides, and any remaining questions about the role, team, or technology domain. This is also an opportunity for you to learn more about our culture and ways of working

The perks of being a payabl.er:

• Future-Proof Your Finances: Once you've passed probation, we'll kickstart your Provident Fund to secure your future.
• Grow with Us: Annual Learning Budget for professional development (eligible after probation)—because your growth is our growth.
• Wolt Your Way Through Lunch: €150 monthly Wolt allowance to keep you fueled and happy
• Stay Active Your Way: Enjoy a SportsBenefits membership giving you access to a wide variety of gyms and sports facilities to support your active lifestyle
• Drive in Style: After one year with us, you may be eligible for a company car—performance and availability permitting.
• Park with Ease: Complimentary parking space just steps from the office, so your commute is as smooth as your workday
• Max Out Your Downtime: 25 days of vacation + public holidays + 10 days of sick leave
• Shop & Save: Exclusive local discount card + tickets for exciting events like Beonix, basketball games, and more.
• Speak Like a Local: Join free Greek language classes, twice a week, open to all team members.
• Celebrate Together: We bring colleagues from all offices together for unforgettable company celebrations
• Global Collaboration & Events: Opportunities to participate in international company events and initiatives, connecting with colleagues from all regions and contributing to a truly global community

The benefits listed above are for our Cyprus office location only, a list of benefits and contract type will be assessed subject to your location and discussed in the first interview with your Talent Acquisition Partner.
Let's embark on a journey to redefine the landscape of payments together. We're not just offering a role; we're inviting you to be a part of something bigger. Join our team, and let's innovate, disrupt, and lead the future of payments. Together, we can make an impact that resonates. Welcome to the team!

Please review our Privacy Policy to understand how we process your personal data during the recruitment process: https://payabl.com/privacy\-policy

You'll define the technical direction for a mission-critical, regulated platform, driving its evolution towards a more scalable and resilient architecture while keeping a live trading system running 24/7.

• Architecture ownership:
  Define the target-state architecture for the trading backend and lead a pragmatic, low-risk evolution toward more modular, independently deployable, and horizontally scalable services
• Resilience & scale:
  Strengthen the platform's ability to scale and fail over safely, making capacity and deployment changes predictable, validated, and reversible
• Execution quality & latency:
  Ensure critical paths - risk evaluation, stop-out / close-out, margin, and order execution - behave correctly and with predictable latency, including under peak load and high-volatility market events
• Engineering standards:
  Establish patterns, performance budgets, observability, and testing practices for a real-time trading system, and mentor senior engineers
• Technical leadership:
  Lead through code and design - write reference implementations, run the hardest investigations, and turn incident learnings into durable architecture
• Cross-functional partnership:
  Work closely with SRE/infra, risk, product, pricing, compliance, and the client-facing teams (web, mobile, partner APIs) whose contracts depend on the core

About you

You are an experienced technical leader who has built and evolved large-scale, business-critical trading platforms. You enjoy solving complex engineering problems, thrive in high-performance environments and are passionate about building resilient systems where every millisecond matters.

You bring:

• Deep expertise building trading-core or execution-engine backends within a broker, exchange or trading venue

• Strong hands-on knowledge of trading platform risk management, margin calculations, order execution and real-time financial processing
• Experience designing scalable distributed systems with strong resilience, messaging and failover capabilities
• A proven track record of modernising complex production systems while maintaining availability and stability

Highly desirable

• Experience extending trading platforms with new derivative products or trading functionality
