Senior Software Engineer, Product Security

About us Pomelo Care is the leading virtual medical practice for women and children, providing care across pregnancy, postpartum, pediatrics, menopause, and perimenopause. We combine proactive, 24/7 clinical care with technology that helps us reach patients earlier, identify risks sooner, and deliver personalized care throughout their journey. Our team includes clinicians, technologists, operators, and problem-solvers working together to make high-quality care more accessible for families nationwide. What you'll do As our first Product Security Engineer, you will sit at the intersection of Security and Software Engineering. Reporting through our Security Engineering function, you will be a "Security Builder": embedded within our engineering teams with the autonomy needed to build the automation, tools, and workflows that make security a seamless part of the software development lifecycle. This is a unique opportunity for a talented software engineer with a passion for cybersecurity to pivot into a full-time security role and help us protect mission-critical systems, applications, and valuable patient data at Pomelo. You aren't just finding bugs; you are building the systems that prevent and fix them at scale. Your work will be centered on three core strategic pillars: Secure architecture and auth: you will design and implement auth enhancements such as magic link improvements and access/audit log features to monitor access and improve transparency. Privacy engineering: you will lead the privacy engineering initiatives including DSAR integration, building automated data deletion capabilities directly into the Pomelo mobile app and our internal platform to ensure seamless compliance. You will also help improve privacy-preserving data de-identification and anonymization as needed. Full-cycle remediation: you will own the end-to-end pentest-to-fix lifecycle. This means you don't just triage reports; you write the code to fix penetration test findings, remediate SAST issues, and build greenkeeping systems for high-volume dependency patching with regression testing. Beyond these pillars, you will serve as a high-leverage engineering partner to the broader InfoSec team by: Building secure-by-default libraries: reducing the load on core Software Engineering by creating internal libraries and patterns that make security the default path. Threat modeling: partnering with engineering leads to conduct threat modeling and ensure secure design at the earliest stages of the development process. Scaling through collaboration: as a security resource embedded in our engineering teams, you will help engineering squads navigate complex security use cases, translating GRC requirements into elegant code rather than manual checklists. Who you are You’re an enthusiastic and collaborative engineer who enjoys solving meaningful problems through code. You view security as a product challenge, and you believe the best way to secure a system is to make the "secure way" the "easy way." In particular, you: Your foundation is in Engineering: You have 5+ years of software engineering experience and are ready to pivot to a full-time security role, bringing a strong foundation in computer science and a track record of shipping production-grade code (Python, Go, Kotlin or similar). Have a security mindset: You understand the OWASP Top 10, identity flows and prompt injections, but you’d rather build a system that eliminates a class of vulnerability than manually triage individual alerts. You believe security expertise should be embedded into the development process, not bolted on at the end. Are an automation enthusiast: you enjoy tackling complex problems with practical automation and are keeping up with trends in LLM agents to multiply your engineering impact. Navigate ambiguity: as a floating resource across various engineering teams, you are comfortable context-switching and can quickly build rapport with different engineering teams to understand their needs.
