Job description

[\]formal is an AI transformation partner dedicated to turning technology promises into real, measurable business benefits. By blending Eightfold’s top-tier AI engineering with our thoughtful approach to strategy and execution, we support organizations in moving beyond the hype to achieve clear, scalable, and impactful results.

What You’ll Be Doing

• Lead the technical architecture of large-scale Eightfold implementations for enterprise clients, often some of the world's biggest companies. Own technical decisions from discovery through go-live, tackling complex integrations, high-volume data, and challenging migrations.
• Sit across the table from CIOs, IT directors, and CHROs, push back when needed, and turn ambitious goals into architectures that will hold up at scale.
• Get hands‑on when it counts: write and debug code, troubleshoot JSON configurations, trace API calls, and find the root cause others missed.
• Join pre‑sales conversations to run technical discovery, shape solutions, scope work realistically, and present architectures that win trust.
• Partner closely with the Delivery Manager to define and uphold technical standards, integration patterns, and data governance practices across projects.
• Raise the technical bar across the delivery organization by mentoring consultants, reviewing designs, and developing reusable solutions that make the entire team better.
• Track Eightfold's roadmap ahead of time and decide how new capabilities should change the way we deliver.
• Develop deep expertise in HR technology ecosystems and talent processes, ensuring technical decisions support real business needs and end‑to‑end workflows.

What You Bring

• 10+ years of experience in enterprise SaaS implementations, technical architecture, or systems integration, with expertise in complex data schemas, high-volume ETL, and large-scale migrations.
• Strong experience with enterprise SaaS ecosystems (e.g., HR tech, CRM, ERP), with the ability to quickly develop expertise in HR technology and business processes.
• Experience designing and delivering integration architectures that are scalable, secure, and performant.
• Strong technical proficiency in JSON, APIs (REST, SOAP), file-based integrations, and common integration patterns.
• Hands‑on programming or scripting experience (Python or equivalent), with the ability to read, write, and debug code independently.
• Exceptional technical judgment and problem‑solving skills, with the ability to turn ambiguous, high‑stakes challenges into practical solutions without waiting for a playbook.
• Executive presence: you can explain a data architecture to engineers in the morning and defend it to a C‑suite in the afternoon.
• A collaborative leadership style. You lead through influence, invite debate, and develop the technical capabilities of those around you.
• Real fluency with AI tools, using them to speed up your work and raise its quality, and helping others do the same.

Highly Desirable

• Experience with HRIS, ATS, or talent platforms such as Workday, SuccessFactors, Oracle, iCIMS, Eightfold, Phenom, or Beamery.
• Experience delivering enterprise‑scale HR technology transformations, including recruiting, talent management, or skills‑based workforce processes.
