What You'll Do

• Own the technical direction of the Account Security group, driving architecture, engineering standards, and long-term technical strategy across multiple teams.
• Be accountable for system design, architecture, code quality, reliability, scalability, and production readiness of mission-critical security services (authentication, MFA, real-time risk, bot protection, and abuse prevention).
• Define and enforce engineering best practices and coding standards, ensuring high-quality, secure, and maintainable code across the group.
• Design and evolve secure, scalable, and highly available backend systems that operate under real-time, high-throughput, and high-risk environments.
• Partner closely with Product, Risk, Data, DevOps, and other R&D teams to align technical solutions with business and security needs.
• Lead technical decision-making and navigate complex trade-offs between security, performance, scalability, and time to market.
• Represent the group in architectural forums and design reviews, sign off on critical designs, and influence company-wide security architecture.
• Proactively identify technical gaps, scalability risks, and security weaknesses, and drive cross-group initiatives to address them.
• Continuously raise the engineering bar through design reviews, code reviews, testing strategies, observability, and operational excellence.
• Mentor senior engineers and emerging technical leaders, shaping technical thinking and ownership across the group.
• Play a key role in hiring, technical interviews, onboarding, and defining what "great" looks like for engineers in the group.

Who You Are

• 7+ years of hands-on backend engineering experience, including leading complex technical systems and influencing architecture across teams.
• Deep expertise in C#, Java, or similar object-oriented languages, with a strong focus on clean architecture and high-scale production systems.
• Advanced SQL and strong database design skills, with experience in performance optimization and data consistency at scale.
• Deep understanding of software design principles, distributed systems, data structures, and algorithms.
• Strong experience building and operating microservices-based architectures in cloud environments.
• Proven ability to lead technically without direct people management, driving alignment, standards, and execution through influence.
• Demonstrated experience solving novel and ambiguous problems, especially in security-sensitive, high-traffic environments.
• Experience working on security-critical domains is a strong advantage: authentication, authorization, fraud prevention, identity, or real-time risk systems.
• Strong collaborator and mentor, capable of elevating the technical capabilities of others.
• BA/BSc in Computer Science, Software Engineering, or equivalent elite technical training (e.g., military technology units such as 8200).

Advantage

• Practical experience with Agile development methodologies.
• Familiarity with cloud platforms such as AWS, Azure, or Google Cloud.
• Knowledge of non-relational databases (e.g., MongoDB).
• Hands-on experience with message queues or streaming platforms like RabbitMQ, SQS, or Kafka.
