Job description

Crusoe's mission is to accelerate the abundance of energy and intelligence. We’re crafting the engine that powers a world where people can create ambitiously with AI — without sacrificing scale, speed, or sustainability.

Be a part of the AI revolution with sustainable technology at Crusoe. Here, you'll drive meaningful innovation, make a tangible impact, and join a team that’s setting the pace for responsible, transformative cloud infrastructure.

About This Role

We’re seeking a Senior API Integration Engineer to serve as a strategic technical partner driving enterprise-wide digital transformation through intelligent automation and scalable system integrations. This role will lead the design and delivery of mission-critical integrations across our People Tech ecosystem, with a strong emphasis on Workday HCM, while setting integration standards, mentoring engineers, and partnering closely with business leaders to modernize workflows at scale.

What You’ll Be Working On
  • Architecting and building enterprise-grade integrations using the Workato ONE platform to enable intelligent workflow automation

  • Designing, developing, and maintaining deep API integrations across Workday HCM and the broader People Tech stack (payroll, ATS, LMS, compensation, benefits, performance, analytics)

  • Leveraging AI-powered automation within Workato to improve efficiency, resiliency, and predictive process optimization

  • Establishing reusable integration architecture patterns, frameworks, and governance standards that scale across both human-led and automated workflows

  • Partnering with business and IT stakeholders to gather requirements, lead discovery sessions, assess ROI, and translate complex needs into scalable technical solutions

  • Leading integration initiatives end-to-end, from concept through deployment, including sprint execution, technical reviews, and delivery accountability

  • Providing senior-level escalation support, ensuring reliability, monitoring, alerting, and incident response for critical integrations

What You’ll Bring to the Team
  • 7+ years of experience as an API Developer or Integration Engineer in enterprise environments

  • 3+ years of hands-on production experience with Workato, ideally with Workato ONE

  • Deep expertise building and operating complex Workato recipes, including error handling, monitoring, batch processing, custom connectors, SDK development, and API collections

  • Interest in and exposure to AI-assisted development workflows and intelligent automation — you don't need to be an expert, but you should be excited about where integration engineering is heading

  • Collaborating with internal software engineering teams to ensure integration patterns and API access are available for custom-built internal tools and automations

  • Proven experience integrating Workday HCM (Core HCM, Recruiting, Talent, Compensation, Time, Absence, Benefits)

  • Strong background integrating People Tech platforms across payroll, ATS, LMS, compensation, performance, and benefits systems

  • Expert knowledge of enterprise integration best practices, EAI/SOA patterns, and iPaaS architectures

  • Proficiency with RESTful APIs, webhooks, JSON/XML, OAuth 2.0, SAML, SOAP, RBAC, and API security best practices

  • Experience with Agile/Scrum delivery, Jira/JSM, Confluence, and CI/CD workflows

  • Strong understanding of HR data models, compliance requirements (e.g., GDPR, SOC 2), and secure handling of sensitive PII

Bonus Points
  • Workato Foundations or Integration Developer certifications

  • Workday certifications or experience with Workday Studio, EIB, and Web Services

  • Experience with additional iPaaS platforms (e.g., MuleSoft, Boomi, Informatica)

  • Background in HR technology consulting or HRIS implementations

  • Experience with cloud platforms (AWS, Azure, GCP), IaC tools, or identity and SSO integrations

  • Experience in high-growth or highly regulated environments

Benefits:

  • Industry competitive pay

  • Restricted Stock Units in a fast growing, well-funded technology company

  • Health insurance package options that include HDHP and PPO, vision, and dental for you and your dependents

  • Employer contributions to HSA accounts

  • Paid Parental Leave

  • Paid life insurance, short-term and long-term disability

  • Teladoc

  • 401(k) with a 100% match up to 4% of salary

  • Generous paid time off and holiday schedule

  • Cell phone reimbursement

  • Tuition reimbursement

  • Subscription to the Calm app

  • MetLife Legal

  • Company paid commuter benefit; $300/month

Compensation Range

Compensation will be paid in the range of up to $165,000 - $200,000 + Bonus. Restricted Stock Units are included in all offers. Compensation to be determined by the applicants knowledge, education, and abilities, as well as internal equity and alignment with market data.
