Senior Software Engineer, Platform

Stack

Responsibilities

• ▹Design, build and operate Payabli's cloud infrastructure, making architectural decisions around networking, compute, storage and security
• ▹Own and evolve CI/CD pipelines end to end: fast, safe, repeatable production pushes, automated testing, staged rollouts, rollback strategies and deployment observability
• ▹Own the local development experience so engineers are productive in minutes and the environment mirrors production closely
• ▹Build environments that let engineers use AI coding agents and assistants safely and effectively within a PCI-compliant infrastructure
• ▹Define and drive the platform roadmap and prioritize infrastructure investments with engineering leadership
• ▹Harden the infrastructure: PCI-DSS scoping, network segmentation, secrets management, access controls and audit trails
• ▹Build the monitoring, alerting and observability stack that gives real-time visibility into system health
• ▹Document patterns, write runbooks and establish infrastructure standards that make the engineering organization more self-sufficient

Requirements

• ▹5+ years of professional infrastructure or platform engineering experience; built and operated production AWS environments serving real traffic at scale, not just sandbox accounts
• ▹Deep AWS expertise: native command of AWS services (ECS/EKS, RDS, Lambda, VPC, IAM, CloudFormation/CDK/Terraform) and understanding of the trade-offs between them
• ▹Strong CI/CD experience: designed and maintained deployment pipelines (GitHub Actions, GitLab CI, Jenkins or similar) that teams trust and rely on
• ▹Infrastructure-as-code fluency: defining infrastructure declaratively, versioning, reviewing and deploying it the way application code is handled
• ▹Security-minded by default: network segmentation, least-privilege access, secrets management, and encryption at rest and in transit, especially in environments handling financial data
• ▹Proactive and opinionated: seeing what is broken or missing, proposing a path forward and driving it without waiting for a ticket
• ▹Strong communication: translating infrastructure decisions into business impact for engineering leadership and explaining complex systems clearly to engineers who are not infrastructure specialists

Nice to have

• ▹Prior experience in fintech, payments or a PCI-DSS-regulated environment
• ▹Experience supporting or enabling AI/ML development workflows, coding agents or LLM-based tooling within engineering teams
• ▹Familiarity with the .NET ecosystem and how it runs on AWS (ECS, App Runner, Lambda, etc.)
• ▹Experience building developer platforms or internal tooling that measurably improved developer velocity
• ▹Background with observability stacks (Datadog, Grafana, CloudWatch, OpenTelemetry) and on-call/incident response processes
• ▹Kubernetes experience, particularly EKS on AWS

Soft skills

What we offer

• ▹Competitive salary
• ▹Stock options with the potential to unlock more equity as the company grows
• ▹Flexible PTO and paid parental leave
• ▹Medical, dental and vision insurance
• ▹401K, HSA and pre-tax savings programs
