WHY PAYNOVATE ?

Paynovate is a Belgium-based fintech with more than 80 employees. As a growing e-money institution, we are bringing payment solutions to the next level. We value ownership, leadership, and the ability to follow through in a context where impact is real and visible.

CONTEXT

We are in the middle of a major infrastructure evolution, moving from a traditional bare-metal environment to a modern and scalable AWS setup. The migration has started and key foundations are already in place.

We are looking for a hands-on technical leader to take this transformation further. This role sits at the core of one of our most strategic initiatives and combines deep technical involvement with technical leadership in a regulated fintech environment.

The infrastructure team currently consists of two engineers with 3 to 5 years of experience. As part of the team's growth, we are strengthening the infrastructure function by recruiting both a Lead System Engineer and an additional System Engineer.

  • Ensure infrastructure implementations comply with PCI-DSS and National Bank of Belgium requirements
  • Manage MySQL databases, including backup, recovery, security, performance tuning, and optimization
  • Mentor junior engineers and contribute to the growth of the infrastructure team
  • Collaborate closely with developers to design scalable, reliable, and secure systems, and communicate technical topics clearly to non-technical stakeholders
  • Troubleshoot software development infrastructure issues (build, deployment, test failures)
  • Help prioritize and follow up on infrastructure-related projects and coordinate with third-party providers
  • Participate in an on-call rotation (shared 24/7 support, approximately 1–2 times per month)
  • Maintain clear and structured technical documentation

What You Bring

  • At least 10 years of experience in systems engineering
  • Strong AWS experience (at scale).
  • Solid expertise in Infrastructure as Code (Terraform, Ansible).
  • Strong Linux and Docker skills.
  • Proficiency in Bash scripting.
  • Good understanding of networking
  • Experience with both on-premise and cloud infrastructure.
  • MySQL database administration (performance, backup and restore)
  • Basic knowledge of HSMs.
  • Experience operating 24/7 production systems.
  • Demonstrated technical leadership skills, with the ability to coach and guide others
  • Strong problem-solving and analytical skills
  • Ability to communicate effiectively with both tech and non-technical audiences
  • Excellent communication skills with technical and non-technical audiences.
  • Proactive, organized, communicative and team-oriented mlindset

What We Offer

  • A key technical role in a profitable and fast-growing fintech environment
  • Direct and tangible impact on a strategic infrastructure transformation
  • A collaborative team environment with room for growth and development
  • A modern working environment with a structured hybrid work policy
  • A competitive salary package including 32 days of holiday, mobility budget, meal vouchers, health and group insurance, phone, and homeworking allowance
