Why Paynovate?

Paynovate is a Belgium based fintech with more than 80 talented employees. We’re building a company where dreams are shaped, where bold initiatives are taken, where your leadership, ownership and ability to follow-through are valued. As a growing e-money institution, we are bringing payment solutions to the next level – and you could be a part of that.



Context

We’re in the middle of a major infrastructure evolution — moving from a traditional, bare-metal environment to a modern, scalable AWS setup. The foundations are there, the migration has begun, and now we’re looking for a technical leader who can take it further.

This role blends hands-on engineering with technical leadership: guiding a team, shaping architecture, and rolling up your sleeves to solve complex problems. You’ll be at the heart of one of our most strategic projects, helping us deliver reliable, secure, and future-ready systems in a high-stakes, regulated environment.

What you’ll do

  • Lead the AWS migration: take our mix of on-prem/data center systems and design, plan, and execute the move to AWS.
  • Maintain legacy systems until their migration to the cloud.
  • Be hands-on: architect, build, fix, and troubleshoot alongside the team.
  • Modernize the stack: Infrastructure as Code (Terraform, Ansible), Docker, AWS services, MySQL.
  • Own compliance: ensure infrastructure meets PCI-DSS and National Bank of Belgium standards.
  • Manage databases: backup, recovery, security, performance tuning, and optimization.
  • Coach and grow: mentor junior engineers (including a talented but less experienced teammate) and help hire the next one.
  • Collaborate cross-team: work with developers to design applications with scalability, reliability, and security in mind, and communicate tech clearly to non-technical stakeholders.
  • Troubleshoot software development infrastructure issues, including build, deployment, and test failures.
  • Coordinate: help prioritize and follow up on infra-related projects, oversee third-party solutions and service providers.
  • Be on-call: shared 24/7 support, about 1–2 times per month.
  • Document: maintain clear and structured technical records.

What you bring

  • Minimum 10 years experience in systems engineering.
    • Strong AWS experience (at scale).
    • Expertise in Infrastructure as Code: Terraform, Ansible/Incebel.
    • Strong Linux and Docker skills.
    • Proficient in Bash scripting.
    • Excellent understanding of networking
    • Balanced knowledge of on-premise and cloud infrastructure.
    • MySQL database administration (performance, backup/restore).
    • Basic knowledge of HSMs.
    • Experience operating 24/7 highly available production systems.
  • Leadership skills
    • Able to coach, delegate, and make decisions.
    • Strong problem-solving and analytical skills.
    • Excellent communication skills with technical and non-technical audiences.
    • Mindset: proactive, organized, communicative, team player, and comfortable stretching beyond your comfort zone.
