£29 - £34 per hourEstimated

About Nscale

Nscale is the GPU cloud engineered for AI. We provide cost-effective, high-performance infrastructure for AI start-ups and large enterprise customers.  Nscale enables AI-focused companies to achieve superior results by reducing the complexity of AI development. Our GPU cloud bolsters technical capabilities and directly supports strategic business outcomes, including cost management, rapid innovation, and environmental responsibility.

We thrive on a culture of relentless innovation, ownership, and accountability, where every team member takes pride in their work and drives it with excellence and urgency. As an Nscaler, you’ll build trust through openness and transparency, where everyone is inspired to do their best work. If you join our team, you’ll be contributing to building the technology that powers the future.

 

About The Role

We're hiring a Systems Integration Engineer to design, build, and maintain the connective tissue between Nscale's rapidly expanding application landscape. As we scale from 1000 to 10,000+ people, our internal systems need to work together seamlessly - not as isolated silos.

This is a hands-on technical role where you'll architect and implement integrations across our core business systems. You'll define integration patterns, build automation workflows, and ensure data flows reliably across the enterprise. You'll work closely with the Senior Director of Systems Integrations to translate business requirements into technical solutions, evaluate integration tools and platforms, and establish standards that enable the company to scale without creating technical debt. This role sits at the intersection of enterprise architecture, solution design, and hands-on implementation.

 

What You'll Be Doing (Responsibilities)

Integration Design & Implementation

  • Design and build integrations between core business systems (ERP, HRIS, CRM, ATS, ITSM, project management, finance, procurement)
  • Implement API-based integrations, webhooks, scheduled data syncs, and event-driven workflows
  • Work with the Palantir Foundry team to enable as the primary integration platform
  • Build and maintain data transformation logic, field mappings, and validation rules
  • Design error handling, retry logic, and monitoring for production integrations Solution Architecture
  • Act as technical advisor for integration requirements - translating business needs into technical designs
  • Define integration patterns and standards (REST APIs, webhooks, batch ETL, SCIM provisioning, SSO/SAML
  • Evaluate trade-offs between point-to-point, hub-and-spoke, and event-driven architectures
  • Create architectural decision records (ADRs) and integration documentation
  • Collaborate with the Enterprise Architecture function to ensure integrations align with target state architecture

JML Automation (Joiner/Mover/Leaver Workflows)

  • Design and implement automated user lifecycle workflows across the full application estate
  • Build joiners workflow: recruitment platform → HRIS → identity provider → application provisioning → hardware ordering 
  • Build movers workflow: role changes trigger access reviews and re-provisioning
  • Build leavers workflow: termination triggers immediate deprovisioning, device wipe, licence reclaim
  • Ensure JML workflows meet SOX and SOC 2 compliance requirements (auditable, controlled, no manual workarounds)

Data Quality & Governance

  • Ensure data consistency across systems - single source of truth for users, customers, contracts, financial data
  • Build data validation and quality checks into integration pipelines
  • Identify and resolve data sync issues, duplicate records, and mapping errors
  • Work with business owners to define data ownership and master data management rules

Tooling & Platform Evaluation

  • Evaluate and recommend integration tools, platforms, and SaaS connectors
  • Conduct proof-of-concept builds to validate technical feasibility
  • Assess API capabilities, rate limits, authentication methods, and webhook reliability of SaaS platforms
  • Maintain awareness of integration technology landscape and emerging patterns

Operational Support & Monitoring 

  • Monitor integration health - track API errors, failed syncs, data discrepancies
  • Build dashboards and alerting for integration pipelines
  • Troubleshoot integration failures and implement fixes
  • Document runbooks and support procedures for production integrations
  • Provide Level 2/3 support for integration-related issues

Compliance & Audit Support

  • Ensure integrations meet audit and compliance requirements (SOX, SOC 2, ISO 27001)
  • Document data flows, access controls, and change management procedures
  • Support audit evidence collection for ITGCs (IT General Controls)
  • Implement logging and audit trails for sensitive data movements

M&A Integration Support

  • Assess acquired companies' application landscapes and integration points
  • Design integration strategies for merging technology estates
  • Implement system migrations and data consolidation post-acquisition
  • Build repeatable integration playbooks for future acquisitions

 

About You (Skills / Qualifications)

 

Required

  • 3–5 years hands-on experience building enterprise integrations across SaaS applications
  • Strong understanding of REST APIs, webhooks, OAuth/SAML, SCIM provisioning
  • Experience with at least one integration platform (Workato, Celigo, MuleSoft, Boomi, Zapier, Make) or custom API development
  • Proficiency in at least one scripting/programming language (Python, JavaScript, or similar)
  • Experience integrating core business systems: ERP (NetSuite/SAP), HRIS (Workday/BambooHR), CRM (Salesforce/HubSpot), ATS (Greenhouse/Lever) 
  • Solid understanding of data modeling, ETL/ELT patterns, and data transformation logic
  • Experience with Identity & Access Management (IAM) integrations - JumpCloud, Okta, Azure AD, or similar
  • Ability to read and write SQL for data validation and troubleshooting
  • Strong troubleshooting skills - comfortable diving into API logs, requests, JSON payloads

Nice to have

  • Experience with Palantir Foundry or similar enterprise data integration platforms
  • Background in solutions architecture or enterprise architecture for internal systems
  • Experience designing and implementing JML (Joiner/Mover/Leaver) automation workflows
  • Knowledge of SOX, SOC 2, or ISO 27001 compliance requirements for integrations
  • Experience in high-growth tech scale-ups
  • Exposure to M&A integration - assessing and merging application landscapes post-acquisition
  • Familiarity with data governance, master data management (MDM), and data quality frameworks
  • Experience with CI/CD for integration pipelines (version control, automated testing, deployment automation)
