Job description

Paydock is a leading payments orchestration platform, empowering businesses to manage and scale their payment strategies seamlessly. We provide a single, elegant API to connect to a vast ecosystem of payment gateways and methods, simplifying complexity and unlocking new revenue opportunities for our merchants worldwide. As a geodistributed team, we thrive on asynchronous communication and a culture of ownership, trust, and innovation. We're looking for passionate engineers to help us build and maintain the highly available, scalable, and resilient infrastructure that powers global commerce.

The Role

We are seeking an experienced and proactive Senior Site Reliability Engineer (SRE) to join our global infrastructure team. You will be a guardian of our production environment, responsible for its health, performance, and scalability. Your mission is to apply software engineering principles to solve operational problems, automate everything, and ensure our platform exceeds the reliability expectations of our customers.

You’ll work with a talented, distributed team of engineers across different time zones, making your mark on a platform that processes millions of transactions. This role requires a deep passion for eliminating toil, a proactive approach to system stability, and excellent communication skills to thrive in a remote‑first environment.

What You’ll Do

• Architect & Automate: Design, build, and maintain our core infrastructure using Infrastructure as Code (IaC) principles. You’ll be instrumental in evolving our CI/CD pipelines to ensure safe, rapid, and reliable releases.
• Enhance Reliability & Scalability: Proactively identify and address performance bottlenecks, single points of failure, and scalability limits. You’ll define and monitor Service Level Objectives (SLOs) and Service Level Indicators (SLIs) to maintain and improve platform health.
• Champion Observability: Implement and manage comprehensive monitoring, logging, and alerting systems (e.g., Prometheus, Grafana, ELK Stack) to provide deep insights into system behavior and ensure rapid incident detection.
• Lead Incident Management: Participate in our on‑call rotation, acting as a key player in incident response and resolution. You’ll lead blameless post‑mortems to identify root causes and implement preventative measures.
• Collaborate & Empower: Work closely with software engineering teams to foster a culture of reliability. You’ll provide guidance on building resilient services, implementing best practices for observability, and improving the developer experience.
• Secure the Foundation: Implement and maintain security best practices across our cloud infrastructure, ensuring our platform is robust and compliant.

What You’ll Bring

Must‑Haves

• Extensive Cloud Experience: 5+ years of hands‑on experience with a major cloud provider, preferably AWS (EC2, S3, RDS, VPC, IAM, etc.).
• Infrastructure as Code (IaC) Mastery: Deep proficiency with tools like Terraform or CloudFormation to manage infrastructure declaratively.
• Containerization Expertise: Strong experience with Docker and container orchestration systems like Kubernetes (EKS) or ECS.
• CI/CD Pipeline Development: Proven ability to build, optimize, and manage CI/CD pipelines using tools like GitLab CI, Jenkins, or CircleCI.
• Observability Skills: Hands‑on experience with modern monitoring and logging tools (e.g., Prometheus, Grafana, Loki, Alertmanager, ELK Stack).
• Strong Scripting/Coding Ability: Proficiency in at least one programming language, such as Go, Python, or Bash, for automation and tooling.
• Remote Work Pro: Excellent written and verbal communication skills, with a proven ability to work effectively and asynchronously in a distributed team environment.

Nice‑to‑Haves

• Experience in the payments or FinTech industry.
• Familiarity with service mesh technologies like Istio or Linkerd.

Why Join Paydock?

• Work from Anywhere: Enjoy the flexibility and autonomy of a fully remote, geodistributed team.
• Make a Global Impact: Build and scale the infrastructure for a platform trusted by businesses worldwide.
• Culture of Growth: We encourage continuous learning and provide opportunities for professional development in a supportive and collaborative environment.
