Seal Security is a rapidly growing cybersecurity startup. We help customers save developer hours and headaches while reducing both software supply-chain risk and organizational friction- by making the process of remediating open-source vulnerabilities easier and more efficient with fully compatible, security-patched versions of the libraries our customers are using.

We’re backed by top-tier VCs, led by world-class cybersecurity and GTM experts, and recently closed our Series A funding, with numerous Fortune 500 customers

We’re hiring an Open Source Engineering Manager to lead our growing OS team.

As the OS Engineering Manager, you’ll play a dual role: both guiding and mentoring the team and working hands-on to build, deliver, and troubleshoot critical security patches. This is a deeply technical leadership position focused on keeping our customers’ systems secure, resilient, and reliable.

You’ll lead by example- diving into complex debugging and patching challenges, shaping workflows and tooling, and mentoring engineers to elevate their experties. You’ll also collaborate closely with our automation and machine learning teams, driving improvements in patching velocity, reliability, and scale.

This is your opportunity to shape and scale a mission-critical security function at an early-stage startup, driving impact that will resonate across the entire engineering teams.

Are you up for the challenge?

• Lead, mentor, and scale a high-performing team of open-source engineers.
• Drive patch development by actively contributing code, resolving complex issues through debugging and troubleshooting, and guiding team members throughout the process.
• Conduct in-depth security analyses and translate findings into clear, actionable strategies.
• Continuously evaluate and develop new tools for patch automation, vulnerability scanning, and system monitoring.
• Track and report patching KPIs to leadership.
• Collaborate with Customer Success, Sales, and Engineering teams to accelerate patch releases and optimize delivery processes.

• 2+ years of experience in a team lead or management role (formal or informal).
• 3+ years of hands-on experience with high-level programming languages (e.g., Python, JavaScript).
• Proven expertise in low-level programming (e.g., C, Assembly) and strong knowledge of security concepts, including vulnerabilities and exploits.
• Strong understanding of operating systems (Linux/Unix, Windows) and containers.
• Ability to quickly learn and adapt to new software and technologies.

An advantage:

• Experience with vulnerability scanners and remediation tools.
• Familiarity with open-source projects and ecosystems.
• Background in DevSecOps practices or CI/CD pipelines.
