Product Development Engineer

Product Development Engineer

As a Product Development Engineer, you will independently design, implement, and tune threat detections that support both internal SOC operations and customer-facing security outcomes. You are expected to bring a solid understanding of cybersecurity concepts and apply them to solve practical detection challenges at scale. In this role, you will handle a wide range of troubleshooting scenarios raised by internal stakeholders—including DevOps, the SOC, and TAMs—and determine root causes across systems, escalating when appropriate. You will contribute directly to the global tuning of detection logic by identifying patterns that affect detection quality and performance across customer environments. You will also collaborate on cross-functional initiatives to improve detection reliability, performance, and quality, ensuring that what is deployed aligns with SOC workflows and customer impact expectations. Your growing judgment, autonomy, and problem-solving capabilities are critical to the success of the broader Product Development function. As part of your responsibilities, you will validate new product functionality and detections against defined requirements and service criteria. You may create formal bug reports for issues encountered during QA, provided they are reviewed and approved by a Senior Product Development Engineer or Manager.

Functional Responsibilities:

• Independently design, tune, and validate threat detection logic aligned with product requirements
• Conduct quality assurance testing for new features; file bug reports with Manager or Senior PDE approval
• Troubleshoot technical issues raised by internal stakeholders across systems and escalate when needed
• Analyze global detection behavior to identify trends in false positives and lead tuning recommendations.
• Document detection behavior, test cases, and tuning rationale for internal knowledge sharing
• Collaborate cross-functionally to ensure detections align with SOC workflows and customer use cases
• Contribute to refining QA procedures and internal documentation practices

Professional Competencies:

• Accountability: Consistently delivers assigned work with minimal oversight; takes responsibility for outcomes and follows through on escalations
• Initiative: Identifies opportunities to improve detection, tuning, or workflows and suggests actionable improvements
• Communication: Proactively communicates status, blockers, and resolution paths across stakeholders; contributes constructively in cross-team interactions
• Adaptability: Adjusts to shifting priorities, scope, or requirements with minimal disruption; works well in fast-paced or ambiguous situations
• Collaboration: Actively supports teammates; shares context, troubleshooting insights, and documentation to improve team efficiency
• Time Management: Effectively balances multiple tasks or projects; demonstrates focus and reliability under competing priorities
• Attention to Detail: Independently catches false positives, logical gaps, or test failures; contributes to process refinement
• Professionalism: Maintains a consistent, dependable presence in daily work; models integrity and respect in communication and delivery

Qualifications:

• Bachelors Degree in Information Technology or Cyber Security, or equivalent on-the-job experience
• 1-3 years experience in detection engineering, SOC operations, or SIEM utilization
• Demonstrated ability to independently analyze technical requirements and translate them into detection or product-level outcomes
• Strong troubleshooting skills with ability to determine root causes across systems and escalate effectively
• Experience working in high-urgency or cross-functional environments with shifting priorities
• Proven ability to deliver accurate, scalable work both independently and as part of a collaborative team
• Must be dependable, responsive, and detail-oriented with strong communication and documentation habits
