Success at Zelis Healthcare requires more than just coding proficiency; it demands a "systems-thinking" mindset. You must be able to demonstrate how your technical decisions impact the broader financial health of the organization.

Technical & Domain Knowledge – You will be evaluated on your ability to apply engineering best practices to financial data.

The pace is generally professional and structured, focusing on your ability to work independently while contributing to high-impact team goals.

You will likely encounter a mix of technical screens, architectural design sessions, and behavioral interviews. Because this is a role with high accountability, interviewers will look for evidence of your ability to handle ambiguity, prioritize competing initiatives, and maintain the highest standards of data integrity.

The visual timeline above illustrates the typical progression from initial outreach to final decision.

Financial Data Engineering

This is the heart of the role. You must demonstrate that you can handle the complexities of financial data, where accuracy is non-negotiable.

Be ready to go over:

• Auditability and Lineage: Explain how you track data transformations to satisfy regulatory requirements.

As a Data Engineer at Zelis Healthcare, your primary focus is the end-to-end delivery of financial data services. You will act as a technical lead, taking ownership of the architecture and implementation of data pipelines that support everything from revenue and payments to claims and billing.

You will collaborate daily with Finance, Accounting, and FP&A teams. Your work involves translating their business needs into scalable, audit-ready data models. You are expected to be hands-on with Snowflake and DBT, while also setting the engineering standards for the team. This includes conducting code reviews, mentoring junior engineers, and ensuring that all data products meet the organization's stringent quality and observability standards.

A strong candidate for this role possesses a blend of deep technical skill and a mature, ownership-oriented mindset.

• Must-have skills: 7+ years of data engineering experience, 2+ years in a lead role, advanced SQL expertise, and proven experience with Snowflake and cloud-native data platforms.
• Domain experience: Demonstrated ability to work within the finance or accounting domain (general ledger, billing, etc.).
• Nice-to-have skills: Proficiency in Python, experience with AI-assisted development tools, and familiarity with Azure DevOps or similar CI/CD environments.

Q: How difficult are the technical interviews? A: Expect a high level of rigor. Interviewers will focus on your ability to solve real-world problems, so be prepared to explain your design choices and the trade-offs you considered.

Q: What is the team culture like? A: Zelis Healthcare prides itself on a "Get Stuff Done" culture. You will be expected to work with a high degree of independence and accountability, while still being a collaborative partner to the finance and accounting functions.

Q: What is the typical interview-to-offer timeline? A: While it varies, the process is designed to be efficient. Focus on maintaining momentum by clearly communicating your availability and progress throughout the stages.

• Focus on Business Impact: Always connect your technical solutions to the financial or operational outcome. Don't just say you built a pipeline; explain how it enabled a faster financial close or improved reconciliation accuracy.
• Master the Domain: If you haven't worked in healthcare or finance recently, brush up on common financial data models and the challenges of regulated reporting.
• Be Ready for Behavioral Questions: Use the STAR method (Situation, Task, Action, Result) to structure your answers, ensuring you highlight your personal leadership and ownership in every example.
