The Role

Giant Group is developing n8n as a strategic automation and integration platform across the business. We're looking for an experienced n8n Engineer to accelerate delivery of production automation, system integrations and AI-augmented workflows across operational and development functions.

This is a hands-on engineering role. You'll work directly with the UK-based CTO and teams across Giant Group to design, build, test, deploy and support reliable n8n workflows that reduce manual effort, connect key platforms and introduce AI-assisted processing where it creates measurable value.

We're looking for a delivery-focused engineer who can work independently, communicate clearly across locations and time zones, and produce secure, maintainable working solutions rather than specifications alone.

Key Delivery Areas

1. Workflow Engineering

• Design, build, test and deploy production-grade n8n workflows across Giant Group's key operational areas
• Integrate platforms including Microsoft SQL Server, Azure DevOps, Zendesk, Smartsheet, Microsoft 365 and SendGrid
• Engineer workflows with robust validation, exception handling, retries, idempotency where appropriate, logging, monitoring and alerting
• Use modular, reusable workflow patterns and consistent naming/versioning conventions
• Document workflows, dependencies, credentials/configuration requirements and support procedures so internal teams can maintain them

2. AI-Augmented Process Automation

• Implement LLM-augmented workflow steps using approved AI services and APIs, including Anthropic Claude and/or OpenAI where authorised
• Build document parsing, classification, extraction, validation and routing workflows
• Integrate AI-assisted processing into operational processes such as allocations, onboarding and screening support
• Apply human review, confidence thresholds, deterministic rules and audit trails where the process or data sensitivity requires them
• Identify when conventional rules-based automation is more appropriate than an LLM-based approach

3. Integration Architecture

• Build secure integrations between Giant Group systems, including Giant Precision payroll (SQL Server/.NET), iChex/Giant Screening, messaging platforms and external APIs
• Work confidently with REST APIs, webhooks, JSON payloads, authentication, pagination, rate limits and asynchronous processing
• Design reusable integration patterns that can be extended without unnecessary rework
• Apply least-privilege access, secrets management and appropriate data-handling controls, particularly for payroll, identity and screening data

4. Worker & Contractor Communications

• Build and optimise automated notification workflows supporting contractor and worker onboarding
• Implement multi-channel communication logic across email, WhatsApp and SMS, including fallback, delivery tracking and exception handling
• Support scalable communication flows capable of handling high-volume programmes, including volumes of approximately 20,000 workers per week where required

5. Development & Operations Automation

• Build Azure DevOps automations for pull-request triage, notifications, status tracking and engineering workflow support
• Automate test-result aggregation, reporting and operational status information
• Route incidents and alerts from monitoring platforms to the appropriate teams
• Develop automation supporting operational teams, including allocations and onboarding

6. Handover & Knowledge Transfer

• Produce concise technical documentation and runbooks for each production workflow
• Transfer knowledge to Giant Group engineers and operational owners so workflows can be supported and extended internally
• Maintain clear workflow structure, naming, versioning and change records

Technical Environment

n8n (self-hosted) · Microsoft SQL Server · Azure DevOps · Microsoft .NET/C# services · Microsoft 365 (Exchange, SharePoint, Teams) · Zendesk · Smartsheet · SendGrid · Anthropic Claude API and other approved AI services · Respond.io/WhatsApp Business API · Microsoft Azure infrastructure

Connectivity – Nice-to-Have Experience (desirable, not essential — no candidate expected to have all)

Webflow · Twenty · Avaya Call · Microsoft Teams & Teams Webinars · Clay · PostHog · SE Ranking · Sendr · Microsoft Outlook · AWS Email · Google Search Console · Google Analytics · Google Workspace · Google Tag Manager · Microsoft Office (Word, PowerPoint) · LinkedIn Ads Manager · Meta Ads Manager · Reddit Ads · Microsoft/Bing Ads · Bing Webmaster Tools · Trumpet · Mermaid diagrams · Draw.io · Microsoft OneDrive

Essential Experience

• Demonstrable hands-on experience building and operating production n8n workflows (essential)
• Strong REST API and webhook integration skills, including OAuth 2.0, API keys, JWT and secure credential handling
• Strong JavaScript/Node.js capability for n8n expressions, Code nodes, data transformation and workflow logic
• Experience integrating SQL databases; Microsoft SQL Server experience preferred
• Practical experience designing resilient workflows with error handling, retries, logging, alerting and recovery paths
• Ability to diagnose integration failures using logs, API responses and execution data
• Ability to work independently, manage delivery against agreed priorities and communicate blockers early
• Professional written and spoken English sufficient for technical collaboration with UK-based stakeholders

Highly Desirable

• Experience building LLM-augmented n8n workflows using Anthropic, OpenAI or comparable APIs
• Experience with self-hosted n8n, including credentials, environments, deployment, upgrades and operational monitoring
• Familiarity with Microsoft 365 integrations and Azure DevOps APIs
• Experience with WhatsApp Business API or comparable messaging integrations
• Experience with Zendesk and/or Smartsheet APIs
• Background in payroll, HR technology, screening, financial services or another regulated/data-sensitive environment
• Understanding of secure software delivery, source control, testing and change management

How We Work

• Delivery first: working, tested automation is the primary output
• Pragmatic engineering: choose the simplest reliable solution that meets the requirement
• Security by design: treat personal, payroll and screening data appropriately throughout the workflow lifecycle
• Observable automation: production workflows must be supportable, diagnosable and recoverable
• Documentation as part of delivery, not a post-project activity
• Clear communication across distributed teams and UK working hours

What Success Looks Like

• Production n8n workflows operating reliably across priority business processes
• Integrations implemented using reusable, maintainable patterns
• AI-augmented workflows deployed where they provide a clear operational benefit and appropriate controls are in place
• High-volume worker communication flows operating reliably where included in scope
• Monitoring, error handling and support procedures implemented for production workflows
• Clear documentation and runbooks completed
• Internal engineers able to maintain and extend delivered workflows
• A prioritised backlog of further automation opportunities for subsequent phases
