Senior Site Reliability Engineer (EMEA)

Reap; Ireland; On-site; EUR 120,000 - 180,000; Full time

Job summary

Reap is expanding its Site Reliability Engineering practice to own a payments platform, across multiple regions and PCI DSS compliance. You will lead by example, define SLIs/SLOs, and drive infrastructure as code, automation, and self-service capabilities for engineering teams.

You will help design a scalable, secure, and observable platform that supports agent-initiated payments and future growth while maintaining high reliability across the ecosystem.

Qualifications

• Senior Site Reliability Engineer with hands-on experience building and operating large, PCI-compliant cloud platforms.
• Proven ability to drive IaC adoption, define SLIs/SLOs, and lead incident response programs.
• Experience across multiple AWS regions, compliance, security, and financial services considerations.

Responsibilities

• Define reliability metrics (SLIs/SLOs) with product teams and implement budgets.
• Participate in on-call rotations and postmortem processes.
• Shift remaining infrastructure to IaC, reduce drift, and ensure reproducible provisioning.
• Consolidate Terraform state into a coherent, governed codebase with modules.
• Automate account provisioning and environment setup for new regions/services.
• Build self-serve interfaces for provisioning, deployment, and observability.
• Design ephemeral environments for developers and agents with automatic cleanup.
• Implement observability across logging, metrics, and tracing with actionable alerts.
• Own cloud operations for PCI DSS and regulated financial systems.
• Embed security, least-privilege IAM, and network segmentation in infrastructure.
• Enable AI assistants to operate safely with isolated, auditable actions.

Backed by leading investors including Index Ventures and HashKey Capital, Reap is building the future of borderless, stablecoin-enabled finance.

About The Role

Reap is building a Site Reliability Engineering practice, and this role is central to it. We run card issuing, payouts, FX and stablecoin settlement across multiple AWS regions, under PCI DSS and financial regulation. The platform is growing quickly - into new markets, new products, and now agent-initiated payments - and the infrastructure underneath it needs to grow up with it. That means real service ownership, reliability measured in SLIs and SLOs rather than intuition, and a platform that engineering teams can serve themselves from instead of queueing for.

That work is largely still ahead of us, which is the appeal. You will help decide what reliability means at Reap, what the platform looks like, and what good engineering practice is in this domain - rather than inheriting someone else's answers.

This is a deeply hands-on senior individual contributor role. We expect you to lead by example and drive technical excellence through the systems you build, the standards you set, and the way you help the engineers around you level up. The team is deliberately flat and distributed across time zones.

Technologies You'll Use

• Cloud: AWS, multi-account across multiple regions - Transit Gateway, PrivateLink, site-to-site VPN, WAF, KMS


• Compute: ECS/Fargate, Lambda and EKS


• Infrastructure as Code: Terraform and CloudFormation


• CI/CD: GitHub Actions, Argo CD


• Databases: Aurora PostgreSQL, ElastiCache/Redis


• Messaging and streaming: SQS, EventBridge, Kafka


• Observability: New Relic, CloudWatch


• Languages and scripting: Python, Go and Bash

What You'll Do

As a Senior Site Reliability Engineer at Reap, you will join a team of experienced engineers transitioning a DevOps organisation into Site Reliability Engineering. You will own the reliability of a payments platform while rebuilding the foundation it runs on - the lights stay on while the platform gets replaced underneath them. We treat repetitive manual work as a bug in the platform, not a chore for a human, and your job is to delete whole categories of it rather than absorb them faster.

• Define what reliability means here: set SLIs and SLOs with product and engineering teams, introduce error budgets, and make \"ship or stabilise?\" a matter of arithmetic rather than argument


• Take part in our on-call rotation, and help build the incident response and blameless postmortem practice around it


• Drive Reap to full Infrastructure as Code coverage: bring the remaining legacy infrastructure under IaC, and get to no manual provisioning, no drift, and every resource defined, versioned and reproducible


• Consolidate our Terraform estate into a coherent, well-structured codebase with module standards, governance and automated drift detection


• Automate account provisioning and environment setup so that new regions and services can be stood up repeatably and consistently


• Build the golden paths and self-service interfaces that let product and engineering teams provision, deploy and observe without filing a ticket, with escape hatches for the cases they do not cover


• Design and implement an ephemerally environment platform so any developer, and any coding agent, can get an isolated production-like environment on demand and have it cleaned up automatically


• Implement industry-standard observability across logging, metrics and distributed tracing, with alerting that is actionable and trusted


• Own cloud operations for PCI DSS and regulated financial systems - uptime, failover, capacity, disaster recovery and incident response


• Embed security into the infrastructure layer: secrets management, least-privilege IAM, network segmentation and compliance controls


• Build infrastructure that lets AI assistants and agents operate safely: sane blast radius, strong isolation, auditable actions
