Senior Security Engineer

Security at Shakepay is a company-wide responsibility, supported by a small, high-impact team focused on protecting our customers, systems, and data while enabling product velocity and business growth. The Security team works across application and product security, cloud and infrastructure security, enterprise security, security tooling, incident response, and emerging areas such as AI security. We work closely with Engineering, Platform, Risk, Compliance, and Product to build pragmatic controls and scalable security capabilities in a regulated fintech environment.

We’re building a modern security function where automation and thoughtful use of AI help us reduce repetitive operational work and increase our impact. We’re looking for a Senior Security Engineer to help safeguard Shakepay’s infrastructure, products, and customer data while levelling up our AI platform, security capabilities, and observability.

In this role, you’ll be a hands-on technical contributor across multiple associated security domains, such as application, product, infrastructure, enterprise, and observability. You’ll partner closely with engineering teams to design and implement scalable security solutions that balance risk reduction, customer experience, and product growth. You’ll be expected to work in an AI-forward way. Using AI tools, agents, and automation to increase your reach and keep pace with the scope and scale of Security at Shakepay is a core part of the role, not an optional skill.

• Design and drive security solutions across multiple associated domains, including product, internal applications, infrastructure, enterprise systems, and observability.
• Conduct threat modeling for existing systems and new product initiatives.
• Partner with engineering teams to embed security into development and delivery workflows.
• Build, tune, and automate security alerts, detections, observability, and response workflows, using AI and agents where they can increase scale and effectiveness.
• Participate in and help lead incident response as part of the on-call rotation.
• Support governance, compliance, and regulatory efforts (SOC 2, ISO 27001, PCI, etc.).
• Mentor engineers and share security best practices across the organization.
• Help shape security priorities and technical direction while building strong relationships with internal stakeholders and external security vendors.

Benefits:

• Equity benefits: We believe everyone at Shakepay should benefit from building a generational company, so every shaker owns stock options.
• Get paid in bitcoin: You can choose to take a percentage of your salary in bitcoin.
• Remote friendly: With a flexible schedule, you can work on your own time, from home or anywhere.
• Generous vacation: Every team member is expected to take at least 20 days of vacation each year.
• Insurance coverage: We offer health, dental, paramedical, disability, life, and travel coverage.
• Personal development: Every shaker gets a $2,000 yearly budget to spend on learning and development.
• Working from home: Every shaker gets $1,200 to spruce up their home office and a monthly stipend for home and internet expenses.
• Self-sovereignty: We offer a budget for shakers to get a self-hosted wallet and to build a self-hosted node.

Qualifications:

• Strong technical depth in one or more security domains, with the ability to operate effectively across associated domains.
• Strong communication skills, technical judgment, and a clear sense of ownership.
• Hands-on experience with incident response and on-call rotations.
• 5+ years of experience in security engineering, software engineering, or a related technical discipline, with meaningful experience working in security.
• Advanced, hands-on experience using AI tools, agents, and automation to increase the scale and effectiveness of security engineering work.
• Experience working in cloud environments (AWS preferred).
• Experience working in fintech, crypto, or other regulated environments.
• Exposure to product security and influencing product design.
• Experience with AI-assisted security testing, offensive security, vulnerability research, detection engineering, or security observability.
• Knowledge of Bitcoin and excitement to learn more.
• Comfort using Git/GitHub for collaboration and process management.
