Note: The job is a remote job and is open to candidates in USA. Moderna is a biotechnology company advancing mRNA medicines and developing a broad pipeline of programs across diseases. The Senior Security Data Engineer will own and scale vulnerability risk management data products across ingestion, normalization, risk modeling, data quality, operational reporting, and remediation workflows.

Responsibilities

• Design, build, and operate reliable ingestion pipelines for asset, vulnerability, finding, remediation, threat intelligence, and business-context data sources
• Build reusable ingestion patterns that can absorb new sources without brittle, one-off logic
• Support batch and incremental processing patterns from raw source capture through normalized, model-ready data products
• Partner with source-system owners to clarify schema changes, source freshness, field semantics, and operational constraints
• Own transformations from raw evidence into normalized security entities such as assets, vulnerabilities, findings, owners, exposure context, risk-reduction actions, and validation states
• Engineer model-ready features that encode asset ownership, exposure, business importance, exploitability, remediation state, and organizational context
• Support risk model outputs and operational reporting datasets used by remediation owners and leadership
• Model ownership and accountability signals across code, artifacts, platforms, infrastructure, and application contexts to reduce ambiguity in remediation routing
• Make pragmatic normalization decisions for messy, heterogeneous data while documenting assumptions, confidence, and tradeoffs
• Adapt vulnerability detection and triage data flows to support increasing AI-driven finding volume without losing ownership, severity, or remediation context
• Build data foundations for scanning workflows across code repositories, build artifacts, deployed platforms, and runtime environments
• Connect vulnerability signals to remediation workflow needs, including owner routing, action state, validation evidence, exception paths, and closure reporting
• Partner with security, engineering, and platform teams to unify how findings are represented from discovery through remediation
• Implement data quality checks for schema validity, completeness, freshness, duplication, drift, and unexpected distribution changes
• Maintain lineage documentation so risk scores, reports, and owner views can be traced back to source inputs
• Build monitoring, alerting, and runbooks for data pipeline reliability and source degradation
• Partner with downstream users to resolve data defects and improve trust in pipeline outputs
• Prepare reliable, pre-aggregated data products for dashboards, operational views, risk reporting, and experimentation
• Collaborate with partners to translate new questions into durable data features
• Improve data contracts, documentation, and self-service access patterns for technical and non-technical stakeholders
• Continuously refine feature hypotheses and data products as the vulnerability risk model and remediation operating model mature

Skills

• 5+ years of experience in data engineering, analytics engineering, security data engineering, or related technical disciplines
• Strong hands-on proficiency with Python and SQL in production data pipeline environments
• Experience designing, building, and operating ETL/ELT pipelines across heterogeneous source systems
• Experience with data modeling, schema evolution, incremental processing, and data quality controls
• Ability to work with messy, incomplete, or inconsistent datasets and make pragmatic normalization decisions
• Experience supporting data products from source ingestion through reporting, analytics, model inputs, or decision-support outputs
• Experience designing data models that support ownership routing, triage, workflow state, or operational decision-making
• Strong analytical, troubleshooting, documentation, and communication skills
• This position may involve access to technology or data that is subject to U.S. export control laws, including the Export Administration Regulations (EAR). As such, employment is contingent upon the applicant's ability to access export-controlled information in accordance with U.S. law. Due to the nature of the work and regulatory requirements, only individuals who qualify as U.S. persons (citizens, permanent residents, asylees, or refugees) are eligible for this position. For this role Moderna is unable to sponsor non-U.S. persons to apply for an export control license
• Experience with medallion, lakehouse, or data-product architecture patterns
• Experience engineering features for probabilistic, predictive, prioritization, or risk models
• Experience in regulated environments such as biotech, pharmaceutical, healthcare, GxP, SOX, or similar control environments
• Exposure to cybersecurity, vulnerability management, threat intelligence, security operations, or security data platforms
• Exposure to application security, software supply chain security, shift-left scanning, artifact security, platform security, or unified remediation workflows
• Experience building lineage, observability, monitoring, and operational runbooks for critical data pipelines
• Familiarity with orchestration, data catalog, data contract, business intelligence, or operational reporting patterns
• Exposure to AI/Agentic/LLM-assisted coding tools

Benefits

• Competitive healthcare, plus voluntary benefit programs to support your unique needs
• A holistic approach to well-being, with access to fitness, mindfulness, and mental health support
• Family planning benefits, including fertility, adoption, and surrogacy support
• Generous paid time off, including vacation, volunteer days, sabbatical, global recharge days, and a discretionary year-end shutdown
• Savings and investments to help you plan for the future
• Location-specific perks and extras
• The successful candidate may be eligible for an annual discretionary bonus, other incentive compensation, or equity award, subject to company plan eligibility criteria and individual performance.
