- 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

- 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
What the job involves
- 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
- 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
Our take
Crusoe is tackling one of the biggest challenges facing the digital age: the enormous energy demand of data centres and AI infrastructure. As AI models grow more powerful, they require immense computing power (and therefor electricity) to train and operate. This surge in energy use has put some pressure on power grids, driven up costs, and raised environmental concerns. Crusoe is on a mission to make this process more sustainable by finding smarter, cleaner, and more efficient ways to power the data centres that drive modern computing.
The company started out by putting wasted energy to work. Originally known as Crusoe Energy, it captured natural gas that would otherwise be burned off ("flared") at remote oil sites and used it to power modular data centres. Today, Crusoe has evolved into a major player in AI infrastructure, designing and operating large-scale data centres near renewable or stranded energy sources. It's now one of a handful of "neocloud" companies (next-generation cloud providers focused on flexible, efficient computing for AI workloads). And its facilities are helping tech giants like OpenAI handle the massive computing requirements of training advanced AI models.
Recently, Crusoe has attracted some huge investor attention, tripling its valuation to over $10B and raising $1.4B in its latest funding round. It's building OpenAI's first major US data centre campus and even experimenting with bold new frontiers. In partnership with Starcloud, Crusoe plans to deploy the world's first space-based cloud computing infrastructure, powered by solar energy and orbiting the Earth by 2027. If successful, this could redefine how and where computing happens, opening up a cleaner, virtually limitless source of energy for AI's next generation.
