Principal Integration Engineer

Key Responsibilities

• Act as the principal technical authority for integration engineering across Maximus UK, providing deep leadership across Boomi-based integration solutions.

• Define and maintain integration engineering standards, patterns, guardrails, and best practices for system-to-system integrations, APIs, events, and workflows.

• Provide hands-on technical leadership for the design and implementation of complex integrations built on Boomi and related integration technologies.

• Design scalable integration architectures connecting cloud services, SaaS platforms, enterprise applications and data platforms.

• Drive adoption of modern integration patterns, including API-first design, event-driven architectures, microservices-aligned integrations, and reusable integration components.

• Guide the team's technical direction, improve engineering quality, and support consistent delivery standards.

• Lead technical discovery sessions, design workshops, and integration architecture discussions with business stakeholders, architects, product teams, and engineering colleagues.

• Translate business and operational requirements into robust integration designs and implementation plans that balance speed, resilience, supportability, and long-term value.

• Establish governance approaches for integration code quality, peer review, CI/CD, testing, deployment, observability, and operational readiness.

• Ensure integrations are secure by design, with appropriate controls for authentication, authorisation, encryption, auditability, and protection of sensitive data including PII and PHI.

• Drive the development of reusable integration components, frameworks, and reference implementations that improve delivery speed, quality, and consistency across projects.

• Mentor and develop integration engineers, raising technical capability, architectural understanding, and engineering discipline across the integration team.

• Evaluate opportunities to simplify the integration and automation estate, reduce platform dependency, and introduce more cost-effective and flexible integration approaches.

• Collaborate with automation specialists (e.g.

Automation Anywhere engineers) to define clear boundaries between integration and automation layers and ensure coherent end-to-end designs.

• Monitor technology trends, platform capabilities, and industry best practice in integration engineering, using insight and evidence to evolve the organisation's integration roadmap
