• Build Release Confidence Systems: Design and implement automated smoke tests and workflow validations for our most important payment flows, and integrate them into CI and release gates • Improve Environment Fidelity: Make testing and staging behave more like production by improving stability, data hygiene, environment health checks, and repeatable test scenarios • Develop Test Infrastructure: Build frameworks and harnesses for API and event-driven workflow testing, including partner simulations and contract checks where appropriate • Enable Developer Productivity: Build internal self-service tooling and automation that reduces manual steps, improves debugging workflows, and increases engineering velocity • Improve Release Observability and Documentation: Strengthen release dashboards, visibility, and documentation practices to improve triage, bug tracking, and regression prevention over time • Strengthen CI and Developer Workflows: Improve CI speed and signal, reduce flaky tests, and make failures easy to debug with useful artifacts and visibility • Add Operational Guardrails: Partner with engineering to define monitors, canaries, rollout strategies, and rollback patterns for higher-risk changes • Close the Loop on Regressions: Turn production regressions into durable prevention by adding automated checks, checklist steps, improved documentation, or better safety rails

• Own the design, implementation, and operation of shared Resource Plane services used across the organization • Operate and evolve Kafka, RabbitMQ, Redis, and Elasticsearch platforms in production • Apply SRE principles to ensure availability, scalability, reliability, and safe upgrades of stateful systems • Build and maintain Infrastructure-as-Code and GitOps-based automation for provisioning and lifecycle management • Define and enforce supported usage patterns, guardrails, and golden paths for platform consumers • Integrate Resource Plane services into the Internal Developer Platform for self-service consumption • Participate in on-call rotation (initially may include 24x7 weekly rotation; target state is business-hours primary) • Lead incident response, root cause analysis, and reliability improvements for owned services • Collaborate closely with Kubernetes Platform Team, IDP and other teams as required • Act as a senior technical voice in architecture discussions and platform roadmap planning

• Ensure that our platform is compliant with the best industry practices and standards for security (ISO27001, C5, SOC2) • Help us to introduce security on every step of our platform lifecycle • Make sure that all of our services are deployed in a way that makes them highly available. • Developing and maintaining tools for Global Security in order to deliver vulnerability management platforms for application triaging and continuous compliance • Fixing urgent issues and optimizing performance. • Support other team members in their daily work. • Collaborate on platform compliance, risk management, and act as a technical point of contact during escalated incidents such as DDoS or abuse cases. • Audit existing systems, support secure migration to the central platform, and interpret global security and legal requirements in the context of PMS implementations. • Provide guidance on infrastructure-related application security topics, secure encryption practices, and collaborating on secure CSP integrations.
