Be ready to go over:

• Terraform State & Modules – Structuring reusable Terraform modules to deploy cloud data resources across development, staging, and production environments.
• CI/CD Pipelines – Automating data quality testing, unit testing, and deployment of data assets using tools like GitHub Actions or Azure DevOps.
• Monitoring & Alerting – Setting up operational dashboards, logging, and alerting for pipeline failures and performance anomalies.
• Advanced concepts (less common) – Managing Terraform state locks in a team environment, blue-green deployments for data pipelines, and cost-optimization automation.

Example questions or scenarios:

• "Walk us through how you would configure a CI/CD pipeline to automatically test and deploy a new dbt model to production while ensuring zero downtime for downstream dashboard users."
• "How would you use Terraform to provision a secure, private network connection between an Azure Data Factory instance and a secure Azure SQL database?"

As a Data Engineer at Virtual Vocations, your day-to-day work will center on building and maintaining a world-class data platform. You will be responsible for the entire data lifecycle, from ingestion to consumption.

Your primary responsibilities will include:

• Architecting Data Solutions – Designing and implementing core data warehouse architectures, data lakes, and transactional databases that support business intelligence and advanced machine learning initiatives.
• Building Ingestion Pipelines – Developing highly scalable, reliable ETL/ELT pipelines using Azure Data Factory, Apache Airflow, and dbt to ingest high-volume data from various internal and external sources.
• Optimizing Data Platforms – Monitoring, troubleshooting, and tuning cloud data platforms (such as Databricks, BigQuery, or Snowflake) to ensure high performance, cost efficiency, and reliable query execution.
• Enforcing Engineering Standards – Setting and maintaining technical standards for the data team, including version control, automated testing, code reviews, and continuous integration/continuous deployment (CI/CD) pipelines.
• Collaborating Across Teams – Partnering with Product Managers, Data Scientists, and Business Analysts to understand their data requirements, design self-service capabilities, and transform raw data into reusable, well-governed data products.

By driving these initiatives, you will help establish a highly reliable, self-service data culture that empowers everyone at Virtual Vocations to make data-driven decisions with confidence.

We look for candidates who bring a strong blend of software engineering discipline and deep data domain expertise. While we value specific tool experience, we prioritize a strong understanding of fundamental engineering principles.

Technical Requirements

• Programming Languages – Expert-level proficiency in Python and advanced, highly optimized SQL.
• Cloud Platforms – Extensive hands-on experience with at least one major cloud provider, preferably Azure (ADF, ADLS, Databricks) or Google Cloud Platform (BigQuery, Cloud Composer).
• Big Data Technologies – Deep expertise in Apache Spark for distributed data processing and data lakehouse architectures (such as Delta Lake).
• DataOps Tools – Strong proficiency with Terraform for infrastructure as code, and workflow orchestration tools like Apache Airflow or dbt.
• Software Engineering Best Practices – Proven experience implementing CI/CD pipelines, version control (Git), unit testing, and automated data quality checks.

Experience & Education

• Professional Experience – Typically, 3+ years of experience for mid-level roles, 5+ years for Senior/Manager roles, and 10+ years of cloud data engineering experience for Staff-level positions.
• Educational Background – Bachelor’s degree in Computer Science, Data Engineering, Software Engineering, or a related technical discipline, or equivalent relevant practical experience.
• Must-have skills – Experience building production-grade, scalable cloud ETL/ELT pipelines and managing infrastructure programmatically.
• Nice-to-have skills – Experience in a B2B or fintech environment, familiarity with streaming/event-driven architectures (Kafka), and experience deploying machine learning pipelines.

Q: What is the typical timeline from the initial screen to an offer? A: We respect our candidates' time and aim to move through the process efficiently. The entire interview loop typically takes between two to four weeks, depending on scheduling availability. We provide updates and constructive feedback at every stage of the process.

Q: How much preparation time should I dedicate before the technical interviews? A: We recommend spending a few hours reviewing core distributed computing concepts (especially Apache Spark memory management), practicing SQL query optimization, and brushing up on system design principles for cloud data warehouses. Familiarizing yourself with basic Terraform structures is also highly beneficial.

Q: What differentiates successful candidates in the system design round? A: Successful candidates do not just present a single solution; they actively discuss trade-offs. They explain why they chose a specific tool or architecture, how their design handles failure scenarios, how it scales, and how they balance performance with cloud infrastructure costs.

Q: Is Virtual Vocations a fully remote company, and what are the working style expectations? A: Yes, Virtual Vocations is a pioneer in the remote work space and operates as a 100% remote company. We value asynchronous communication, thorough documentation, and self-motivated execution. You must be comfortable managing your own schedule while collaborating closely with remote teammates across different time zones.

Q: How does the team handle data governance and security? A: Data governance is built into our engineering workflow. We use infrastructure as code to manage access controls, enforce strict data classification and masking policies, and integrate automated data quality testing directly into our deployment pipelines.

To help you perform at your absolute best during your interviews, keep these practical tips in mind:

• Communicate Your Thought Process: During coding and system design rounds, talk through your reasoning out loud. Our interviewers are more interested in how you approach and decompose a problem than whether you write flawless syntax on the first try.
• Focus on Trade-offs: In data engineering, there is rarely a single "correct" tool. Whether discussing Spark vs. Pandas, or Snowflake vs. Databricks, always explain the pros and cons of your choices regarding cost, complexity, and maintenance.
• Emphasize Data Quality: Never treat data quality as an afterthought. Throughout your technical discussions, highlight how you would monitor, validate, and test the data flowing through your pipelines to ensure downstream reliability.

• Brush Up on Infrastructure as Code: Be prepared to explain how you manage cloud state and infrastructure lifecycle. Show that you treat infrastructure with the same software engineering discipline as your application code.
• Show Your Remote Collaboration Strengths: Since we are a remote-first organization, highlight your experience with asynchronous collaboration, writing clear technical specifications, and maintaining comprehensive documentation.

Joining Virtual Vocations as a Data Engineer means taking on a highly impactful role where your work directly powers a platform that connects millions of remote job seekers with their dream careers. It is an exciting opportunity to build, scale, and optimize a modern cloud data platform using cutting-edge technologies like Databricks, Spark, Terraform, and Airflow. You will work alongside a passionate, collaborative, and entirely remote team of engineers who value technical excellence and continuous learning.

To prepare effectively, focus your energy on mastering distributed data systems, designing resilient and secure cloud pipelines, and demonstrating strong software engineering practices such as CI/CD and infrastructure automation. Approach your interviews with a problem-solving mindset, be ready to discuss technical trade-offs, and showcase your ability to collaborate in a remote environment.
