Current Employees of Happen Bank: Please apply via your internal Workday Account Happen Bank (formerly LendingClub) is built around a simple purpose: to clear the way to help people turn intention into action, and action into financial progress. That means offering focused products, a frictionless mobile-first experience, and clear terms with no gotchas. Respect and fairness is part of our DNA, and that ideal shapes how we work, how we treat each other, and how we invest in our employees and our community. Join us in using data, bold thinking, and a commitment to innovation to help clear the way for millions of Americans to achieve more. About the Role Happen Bank is building a modern enterprise data and AI platform on Databricks. Our Data Engineers, Data Scientists, and Analytics teams build the pipelines. This team builds what they build on. As a Principal Data Engineer, you'll own the technical architecture and development of the platform frameworks and infrastructure that make downstream pipelines faster, safer, and more consistent. This includes configuration-driven ingestion frameworks, secure connectivity to source systems, reusable data protection libraries for anonymization and tokenization, and the infrastructure-as-code foundation that brings these capabilities together. This is a framework and platform engineering role, not a pipeline-delivery role. Success means enabling teams to onboard new data sources, protect sensitive information, and promote work to production through configuration rather than custom code. What You'll Do Own ingestion architecture: Define the technical vision and architecture for a declarative, configuration-driven ingestion framework that brings data from relational databases and object-store files into the raw data layer. Establish reusable patterns and contracts for downstream teams while evaluating tradeoffs between ingestion approaches Build scalable platform frameworks: Lead the design and implementation of reusable, versioned libraries that support policy-driven data protection, including configurable rules, governed access, consistent outputs, secure-by-default failure behavior, and audit trails. Maintain backward compatibility across shared capabilities used by multiple teams Set infrastructure and deployment standards: Define infrastructure-as-code practices for safe deployment, replacement, rollback, and lifecycle management, including data ownership considerations for managed pipeline objects. Establish compute, cost, and sizing guidance for large initial loads and steady-state incremental processing at billion-row scale Drive platform reliability and observability: Establish monitoring, alerting, reconciliation, recovery, and data validation capabilities that ensure reliable operations from source to destination. Identify and address observability gaps in underlying platform tools Lead evidence-based technology decisions: Conduct structured proofs of concept with measurable success criteria, document architectural decisions and tradeoffs, and engage technology vendors to resolve product gaps and influence future capabilities Drive cross-functional platform delivery: Translate ambiguous technical challenges into clear requirements, interfaces, dependencies, and phased delivery plans. Partner with Data Engineering, Data Governance, Information Security, DBAs, and source-system owners to deliver early solutions while building scalable long-term capabilities and driving framework adoption Raise engineering standards: Mentor senior and staff engineers, lead technical design and code reviews, and establish best practices for testing, documentation, release management, and maintainability across shared platform capabilities About You 10+ years of software or data platform engineering experience, including designing and delivering platform-level frameworks, libraries, or infrastructure used across multiple engineering teams Bachelor's degree or higher, or equivalent combination of education and experience Strong experience with infrastructure as code, including Terraform and CI/CD pipelines for data platforms Deep experience building ingestion capabilities across diverse data sources, including relational databases, files, APIs, and custom systems, with expertise in incremental processing, change data capture (CDC), schema evolution, and protecting production source systems from excessive load Advanced programming skills in Python, SQL, and a JVM language such as Scala or Java, with experience developing Spark UDFs and reusable libraries using strong testing, packaging, and versioning practices Deep hands-on expertise with Databricks, including Delta Lake, Unity Catalog, Auto Loader, workflows, compute configuration, and governance capabilities, or equivalent data platform experience Strong knowledge of security and privacy engineering for sensitive data, including encryption, key management, tokenization or format-preserving techniques, role-based access controls, and audit logging Experience designing and operating large-scale data systems processing billions of rows, including performance testing, cost optimization, monitoring, and recovery strategies Excellent written and verbal communication skills, including the ability to develop clear technical designs, architecture decision records, interface contracts, and documentation while influencing senior stakeholders without direct authority You navigate ambiguous technical challenges, evaluate tradeoffs thoughtfully, and take ownership of delivering durable solutions that improve engineering effectiveness across teams You have deep experience applying AI tools to complex engineering work, including architecture exploration, development, testing, and problem-solving. You help shape how AI is incorporated into engineering workflows while maintaining strong judgment around security, accuracy, maintainability, and where human oversight remains essential Nice to Have Experience in banking, lending, or another regulated environment with model risk management, SOX, or similar audit requirements Experience with data quality, lineage, catalog tooling, and data contract approaches Prior experience as a Principal Engineer, Staff Engineer, or technical lead for a platform engineering team Experience with Databricks Asset Bundles or equivalent deployment tooling Work Location San Francisco The above locations are eligible offices for this role.
