Staff Engineer, Security Engineering

Grubhub is seeking a seasoned Staff-level Software Engineer to design, develop, and maintain security infrastructure and tools to protect the company's platform and data. Grubhub is in growth-mode and we need standardized processes and tools that can be scaled across the organization, to ensure that security measures keep up with the pace of the business. You will work closely with cross-functional teams, including software engineering (FE + BE), IT, and SRE, to ensure our security practices are robust and scalable. Your expertise will help us achieve our goal of building secure, resilient, and efficient systems. A key part of your role will be to develop and maintain "paved roads" for security, creating standardized and streamlined paths that make secure practices the easiest and most efficient options for our teams. This role reports directly to the head of cybersecurity with broad latitude to work with both senior and new-grad engineers to make a measurable impact on Grubhub’s security posture.

Your Impact

• You will enhance the overall security posture of Grubhub by identifying and mitigating security defects proactively.
• You will contribute to a culture of cybersecurity awareness and continuous improvement within the organization, enabling Grubhub to launch and sustain key business initiatives with minimal risk.
• You will champion high-integrity + high-assurance outcomes in order to ensure the delivery of secure and trustworthy experiences
• You’ll tangibly reinforce our #1 technology philosophy: “security first” by integrating security into the development process from the start, rather than as an afterthought.

What You Will Do

• Identify lacking security-sensitive functionality in Grubhub’s applications and services, translating those control gaps into actionable engineering remediation plans and solutions
• Design, build, deploy and drive adoption of embedded security tooling in conjunction with internal services and platform teams
• Perform threat modeling, design, and code reviews to assess security implications and requirements for the introduction of new security systems and technologies
• Drive initiatives with outside teams to re-engineer existing services to ensure that Grubhub remains resilient against the latest security threats
• Bridge security domain knowledge gaps through technical mentorship of a team of passionate engineers while also delivering uniquely challenging projects.

What we’re expecting you to have

• Bachelor's in Computer Science, Engineering or a related field
• Professional experience of 8+ years in at least two security domains: web security (inclusive of APIs, backends, frontend and microservices), edge/perimeter security, mobile security, cloud security, systems security, or reverse engineering
• 7+ years of industry experience in a software development environment with expert-level proficiency in programming languages like Java, Python, or C++
• Demonstrable experience developing libraries and frameworks that are pre-vetted for security, which developers can use to avoid common vulnerabilities.
• Hands-on experience incorporating security checks and tests into the CI/CD pipeline so that every code change is automatically reviewed for security issues before it is deployed.
• Demonstrable experience in conducting code reviews to identify security deficiencies in how business logic is implemented.
• Experience designing, implementing, and deploying production-quality security engineering systems and incorporating security standards into supporting subsystems as needed.
• Hands-on experience with middleware, message queues, caches, and other related technologies.
• Strong experience in architecture design, high-availability, high-performance, distributed systems and working with 5x9/ zero-downtime systems.
• Demonstrable commitment to engineering and operational excellence–to include development + monitoring of SLOs/SLIs to assure adherence to EOE standards–with direct experience in driving security outcomes within an engineering culture.
• A broad knowledge of attack vectors, exploits and mitigations that work at scale or may be linked together for chained attacks
• Working familiarity with version control systems (Git), issue tracking tools (Jira) and ability to define + support your commitments within an Agile working model.
• Ability to communicate ideas and proposals concisely to a wide-range of audiences
• Ability to author both technical and non-technical documentation on a continuous cadence.
• Ability to fully participate in our on-call rotation as a service owner

What does a strong candidate have?

• Master’s (or Ph.D) in Computer Science, Engineering or a related field
• A security industry-related certification such as Certified Information Systems Security Professional (CISSP) or Offensive Security Certified Professional (OSCP)
• Knowledge of both iOS and Android architecture and development
• Expert-level knowledge within identity and access management security domain, inclusive of role-based access controls, factors-based authentication and identity-based attack (both legacy and emergent) patterns.
• Willingness to participate in incidents as needed as a security SME
• Familiarity with industry-standard threat modeling, risk modeling and vulnerability classification.
• Prior experience leading the design or reconstruction of complex systems, preferably in e-commerce or retail-related fields.
• Deep understanding of the related theories of distributed systems, such as load balancing, distributed transactions, CAP/BASE, etc
• (Bonus) Experience with hardware or embedded device security such as what you would find in a kiosk or a point-of-sale system
