Platform Engineer in Newcastle upon Tyne

Who We Are

Inspired by a shared love of fashion, sneakers and the surrounding culture, END. was founded in Newcastle upon Tyne in 2005. The first UK store brought together a curated mix of celebrated designers and emerging brands, many of which were previously hard to find outside of London. From day one, the company nurtured a community of like‑minded individuals united by a love for this ever‑evolving culture. Today, END. serves over 2 million customers worldwide through a seamless blend of online and physical retail. The industry‑leading stores in Newcastle, Glasgow, Manchester, London, and Milan reflect a commitment to innovation, influence and inspiration. A carefully curated selection of menswear, womenswear, sneakers, homeware and lifestyle products is offered to a global audience. At the heart of END. is the customer, and it’s the people and culture that make the difference. With over 600 employees across headquarters, offices and retail locations, a customer‑first mindset continues to guide everything the company does.

The Role

Own the reliability, security, performance and day‑to‑day operational excellence of the Shopify Plus platform and its critical integration ecosystem (Shopify Patchworks D365). The role leads observability, incident response, stability and problem management, and operational governance that keeps trading safe and predictable. It also takes 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 and clear escalation paths).

Responsibilities

• CI/CD maintenance & governance: maintain vendor‑delivered pipelines for themes, apps and integration services; manage access, configurations, release controls and quality gates; ensure pipelines remain reliable, secure and well‑documented.
• Release & change governance: own the change calendar, release readiness checks, environment parity checks and exception processes during freeze/peak windows.
• Shopify Plus security posture: understand Shopify‑managed protections and operate the process to engage Shopify Plus Support when needed.
• Observability & monitoring: define and maintain dashboards and alerts across the storefront experience (RUM and synthetics) and integration services; ensure actionable alerting, clear ownership and ongoing tuning.
• Service ownership & SLOs: define ownership boundaries, SLI/SLOs (availability, latency, data freshness), alert thresholds and regular reporting for platform and integration services.
• Incident management, stability & problem management: lead triage, stakeholder communication, mitigation, RCA and preventative actions; maintain a stability backlog and drive repeat‑incident themes to closure to improve MTTR and reduce recurrence.
• Integration runtime operations: 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.
• Data reconciliation & control reporting: implement operational controls for key flows (orders, inventory, pricing, fulfilment) including mismatch detection, audit trails and repeatable replay/backfill procedures.
• D365 environment management: oversee Dev/Sandbox, UAT and Production environments (access, refresh cadence, config hygiene and release readiness).
• D365 upgrades & release support: manage D365 version upgrades by testing in lower environments first; coordinate regression validation and go/no‑go decisioning.
• D365 licence, storage & cost observability: manage user licence reviews and access governance; monitor and optimise storage and capacity; track and report cost/consumption drivers and optimisation actions.
• Security & compliance controls: secrets management, least privilege, auditability, dependency hygiene and secure configuration for apps and services; coordinate security reviews and remediation plans.
• Peak readiness & resilience: trading‑event readiness plans (monitoring uplift, incident playbooks, change risk controls and freeze coordination, validation checklists) and business continuity procedures for integration failures.
• Vendor/platform escalation: manage Shopify Plus, Patchworks and D365 support escalations with evidence packs and track actions to closure.
• Access governance & audit: run periodic access reviews across Shopify apps, Patchworks and D365; maintain joiner/mover/leaver processes and audit evidence.
• Platform documentation & guardrails: maintain runbooks, operational standards and “how‑to‑operate” documentation; ensure onboarding for engineering and support is clear and current.

Qualifications

• Platform/SRE/operations experience supporting high‑traffic e‑commerce, 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 SLI/SLOs, improving alert quality, incident analysis, RCA/problem management, measurable MTTR/incident reduction.
• Strong integration operations experience across iPaaS and 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 and implementing controls in the layers you own (apps, services, integrations, tooling, processes, vendor escalation).
• Experience operating/supporting D365 environments (Dev, Sandbox, UAT, Prod): environment management, release coordination, upgrade rehearsals, lower‑environment testing and go/no‑go support.
• Strong governance capability: access reviews, least privilege, audit evidence and secure operational practices across Shopify, Patchworks and D365 and monitoring tools.
• Experience with D365 licensing and capacity/storage management, plus cost observability and optimisation.
• Strong stakeholder management under pressure: clear communication, 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 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 e‑commerce journeys, including peak‑readiness monitoring uplift.
