Successful candidates will need to pass a standard background check.

What we offer

• Work that matters in the financial domain: Work on a trading system at an established financial institution, processing millions of transactions daily.

• Professional growth: Collaborate with smart, highly capable developers in a supportive and challenging environment.

• Direct collaboration: You will work directly with the bank’s team in North America and in Poland.

• 1st-tier work: This is not a technical support or legacy maintenance role. The system is functional and is actively being built and you will take part in updating it. The people who built the system are still part of the team.

• Long-term commitment: This is not a fixed-scope or fixed-term outsourcing role; we value people who want to grow and contribute long-term.

• Fully remote work: Fully remote position based in Poland.

• Competitive Compensation: Above-average pay and ample time-off options.

Responsibilities

• Own one or more technology domains end-to-end such as the AWS multi-account landing zone (Control Tower, SCPs, Organizations, IAM Identity Center), EKS greenfield buildout (service mesh, GitOps/ArgoCD, Karpenter), CI/CD pipeline architecture, or AI/ML infrastructure (Bedrock, GPU workloads, MLOps).

• Lead platform buildouts from design through production. Architect, implement, and operate the systems your domain covers, making and documenting architecture decisions within your scope.

• Author and enforce IaC standards. Write production-grade Terraform/Terragrunt modules and establish patterns the entire team adopts.

• Design and implement CI/CD pipelines for infrastructure and application workloads using Jenkins on ECS and GitOps workflows.

• Understand and troubleshoot hybrid connectivity across co-location facilities, AWS Transit Gateway, Direct Connect, and cross-region networking; partner with the Networks team to resolve issues and implement changes.

• Mentor two Mid-level Engineers (L3). Review code and designs, pair on complex problems, drive their technical growth.

• Collaborate with the Governance and Security SME on security posture, vulnerability remediation prioritization, and regulatory compliance.

• Participate in on-call as a senior escalation point for production infrastructure incidents.

• Leverage AI-assisted developer tooling to accelerate delivery and reduce operational toil across the team.

Requirements

Must have

• 6+ years building and operating production infrastructure on AWS.

• Deep expertise in at least one of: AWS multi-account architecture (Control Tower, SCPs, Organizations, TGW) or Kubernetes at scale (EKS, service mesh, GitOps/ArgoCD, Karpenter).

• Terraform and Terragrunt proficiency. You create the modules, not just consume them.

• CI/CD pipeline design and maintenance (Jenkins, GitHub Actions, or equivalent).

• Linux systems administration (Amazon Linux, RHEL, or equivalent).

• Python and Bash scripting for automation.

• Experience mentoring engineers through code reviews, design reviews, and pairing.

• Ability to take ambiguous problems, ask the right questions, and deliver without hand-holding.
