Principal Algorithms & Data System Engineer

PRINCIPAL ALGORITHMS & DATA SYSTEMS ENGINEER

SUMMARY OF ROLE:

Imagine building algorithms that directly save lives. At Element Science, we're on a mission to change how sudden cardiac events are detected, treated, and prevented, starting with our breakthrough wearable technology. As our Principal Algorithms & Data Systems Engineer, you'll lead the development of cutting-edge algorithms that power life-saving interventions and provide data insights that shape our future product evolution. This is a rare opportunity to operate at the intersection of machine learning, physiological signal processing, and cloud-scale data analysis with the chance to see your work make a direct, tangible impact on patient lives. If you have the following, we would love to hear from you:

• You’re a hands-on technical leader who thrives in startup environments and enjoys working close to both product development and patient outcomes.

• You’re fluent in the language of data, and confident architecting algorithmic solutions that span edge devices and the cloud.

• You’ve led complex algorithm efforts from concept through regulatory approval and commercialization and understand the rigor required in the medical space.

• You balance theory and pragmatism; you know when to reach for deep learning vs. robust signal processing, and how to explain your decisions to a cross-functional team.

This is a hybrid role based in our Potrero Hill, San Francisco, California office.

RESPONSIBILITIES:

• Invent and lead the design, development, and testing of algorithms used to detect and respond to critical cardiac events in our wearable medical device.

• Shape the future of our Cloud-based analytics platform, developing algorithms that interpret device data and generate meaningful clinical and operational insights.

• Collaborate cross-functionally to define system-level requirements, data flows, and scalable machine learning pipelines in partnership with Software, Cloud, and Product teams.

• Build the foundation for scalable ML development processes, from data curation to model validation and deployment.

• Lead with influence, serving as a technical mentor across engineering and contributing to the strategic direction of our data science roadmap.

• Support clinical and commercial success by providing robust, validated algorithms and hands-on support during studies, deployments, and product iterations.

QUALIFICATIONS:

• Bachelor’s degree in CS, EE, Physics, Math, or related field; advanced degree preferred.

• 8+ years of industry experience in algorithm development, ideally including regulated product development (e.g., medical devices).

• Deep knowledge of ML fundamentals, model selection, training, and validation.

• Strong mathematical foundation: linear algebra, statistics, optimization.

• Expert in Python (NumPy, SciPy, scikit-learn, etc.). MATLAB proficiency is a bonus; C/C++ familiarity helpful for embedded understanding.

• Experience working in or leading cross-functional teams including software, systems, and clinical development.

• Proven success navigating algorithm development from feasibility to commercial launch.

• Strong written and verbal communication skills.

EEXTRA CREDIT (Nice to Have, NOT Required): 

• Physiological signals (ECG, PPG, EEG, etc.)

• Digital signal processing techniques

• AWS or other cloud platforms for data processing

• Predictive analytics in a healthcare or clinical setting

• Building compliant pipelines in GxP, HIPAA, or FDA-regulated environments

BENEFITS:

Element Science offers a very competitive salary and benefits package including, but not limited to:

• Stock Options
• 90% employer-paid medical, dental, and vision insurance
• Company-paid Basic Life Insurance
• 401(k) retirement plan (Traditional and Roth)
• Competitive Paid Time Off
• Paid Holidays
• FSA (Flexible Spending Accounts)
• HSA (Health Savings Account)
• Employee Assistance Program through PEO

The salary for this exempt-level position will be based on experience and qualifications within an established pay range.

• Pay range: $200,000 - $210,000
