Platform Engineer

Job summary

The Platform Engineer will be responsible for the reliability, security, performance, and day-to-day operational excellence of the Shopify Plus platform and its critical integration ecosystem.

The engineer will also take ownership of vendor-delivered CI/CD pipelines, maintaining release controls, access, configuration, and continuous improvement within Shopify's SaaS constraints.

Benefits

Qualifications

• Platform/SRE/operations experience supporting high-traffic ecommerce, with strong incident management and operational discipline
• Experience maintaining CI/CD pipelines delivered by others (e.g., GitHub Actions/Azure DevOps): permissions, secrets, environment configs, release controls/quality gates, and troubleshooting
• Strong observability and reliability engineering experience (New Relic/Sentry/Datadog/etc.): defining SLIs/SLOs, improving alert quality, incident analysis, RCA/problem management, and measurable MTTR/incident reduction
• Strong integration operations experience across iPaaS/ERP flows: queues/backpressure, rate-limiting, idempotency, retries/DLQs, replay/backfill, reconciliation, and data integrity monitoring
• Practical understanding of operating within Shopify Plus SaaS constraints (limited edge/WAF control) and implementing controls in the layers you do own (apps, services, integrations, tooling, processes, vendor escalation)
• Experience operating/supporting D365 environments (Dev/Sandbox, UAT, Prod): environment management, release coordination, upgrade rehearsals/testing in lower environments, and go/no-go support
• Strong governance capability: access reviews (joiner/mover/leaver), least privilege, audit evidence, and secure operational practices across Shopify/Patchworks/D365 and monitoring tools
• Experience with D365 licensing and capacity/storage management, plus cost observability and optimisation
• Strong stakeholder management under pressure: clear communications, structured updates, escalation with evidence packs, and calm coordination during peak/trading events
• Strong Shopify Plus operational knowledge: Admin API/GraphQL + webhooks, rate-limit strategies, bulk operations, and navigating Shopify Plus support/escalation processes
• Patchworks (or similar iPaaS) experience: mapping/versioning, error handling patterns, replay/reprocessing, and operational reporting
• Hands-on D365 platform administration: environment refreshes, release validation, upgrade rehearsals, role/security model familiarity, and capacity/storage optimisation
• Infrastructure-as-Code familiarity (Terraform or equivalent) for the integration/runtime layer (cloud resources, queues, secrets, monitoring as code)
• Experience with SLO tooling and incident/problem management practices (post-incident reviews, stability backlogs, automation/runbook maturity)
• Experience implementing synthetic monitoring and RUM for ecommerce journeys, including peak-readiness monitoring uplift

Responsibilities

• Own the reliability, security, performance, and day-to-day operational excellence of the Shopify Plus platform and its critical integration ecosystem (Shopify Patchworks D365)
• Lead observability, incident response, stability and problem management, and the operational governance that keeps trading safe and predictable
• Take BAU ownership of vendor-delivered CI/CD pipelines—maintaining release controls, access and configuration, and continuous improvement—while operating effectively within Shopify's SaaS constraints (Shopify-managed hosting/CDN/WAF, with clear escalation paths where required)
• Maintain vendor-delivered pipelines for themes/apps/integration services; manage access, configurations, release controls, and quality gates; ensure pipelines remain reliable, secure, and well-documented
• Own the change calendar, release readiness checks, environment parity checks, and exception processes during freeze/peak windows
• Understand Shopify-managed protections and operate the process to engage Shopify Plus Support (e.g., bot protection schedules) when required
• Define and maintain dashboards/alerts across storefront experience (RUM/synthetics where available) and integration services; ensure actionable alerting, clear ownership, and on-going tuning
• Define ownership boundaries, SLIs/SLOs (availability, latency, data freshness), alert thresholds, and regular reporting for platform and integration services
• Lead triage, stakeholder communications, mitigation, RCA and preventative actions; maintain a stability backlog and drive repeat-incident themes to closure to improve MTTR and reduce recurrence
• Operational ownership of Shopify APIs/webhooks and Patchworks/D365 flows—rate-limit safe patterns, idempotent processing, retries/DLQs, replay tooling, reconciliation, and data correctness checks
• Implement operational controls for key flows (orders, inventory, pricing, fulfilment) including mismatch detection, audit trails, and repeatable replay/backfill procedures
• Oversee Dev/Sandbox, UAT and Production environments (access, refresh cadence, config hygiene, and release readiness)
• Manage D365 version upgrades by testing in lower environments first; coordinate regression validation and go/no-go decisioning
• Manage user/licence reviews and access governance; monitor and optimise storage/capacity; track and report cost/consumption drivers and optimisation actions
• Manage secrets, least privilege, auditability, dependency hygiene, and secure configuration for apps/services; coordinate security reviews and remediation plans
• Develop trading-event readiness plans (monitoring uplift, incident playbooks, change risk controls/freeze coordination, validation checklists) and business continuity/degraded-mode procedures for integration failures
• Manage Shopify Plus / Patchworks / D365 support escalations with evidence packs (logs, timelines, impact) and track actions to closure
• Run periodic access reviews across Shopify apps, Patchworks, D365, and monitoring tooling; maintain joiner/mover/leaver processes and audit evidence
• Maintain runbooks, operational standards, and “how-to-operate” documentation; ensure onboarding for Engineering/Support is clear and current
